•Overview

•Managing Circuits

•Managing BLSRs

•Managing MS-SPRings

•Managing VLANs for E-Series Cards

•Managing VLANs (ML-Series Cards)

•Managing VLAN Database Profile

•Provisioning Data Services

•Managing QoS Profiles

•What Is Connection Provisioning?

7.1  Overview

A metro network is a network that aggregates customer traffic and connects customers to services. The metro network is responsible for receiving network traffic from long-haul transport networks and routing this traffic to and from enterprises and end users.

The service point-of-presence (POP) performs service adaptation and packet switching. This layer performs the following functions:

•Grooming of traffic from the metro network

•Edge packet switching, where IP services are enabled

•Core packet switching, where POPs are interconnected over the IP backbone

The service POP is the hub of high-value Internet services. The core network, where optical technologies predominate, is the domain of the long-haul carrier. This high-speed transport fabric interconnects service POPs and has traditionally been built as SONET ring architectures.

CTM simplifies operations support system (OSS) integration for service providers for the end-to-end management of transport networks.

7.2  Managing Circuits

A circuit represents an end-to-end connection between two or more connection termination points (CTPs). A circuit consists of an alternating series of cross-connections and link connections. In its simplest form, a circuit consists of a single cross-connection (if the circuit is defined between two CTPs on the same NE). A circuit can be bidirectional or unidirectional, point-to-point (PTP) or point-to-multipoint, and protected or unprotected.

CTM allows you to create unidirectional and bidirectional circuits for CTC-based NEs and DWDM optical channel client connection (OCHCC) circuits for CRS-1 NEs. For unidirectional path switched ring (UPSR) circuits, you can create revertive or nonrevertive circuits. CTM can route the circuits automatically, or you can route them manually. For CRS-1 and CTC-based NEs (including the ONS 15305 R3.0), circuits can be viewed, created, modified, traced, and deleted. For the ONS 15530 or ONS 15540, a circuit is an end-to-end connection between two ports on ONS 15530 or ONS 15540 NEs in terms of lambda (wavelength). For the ONS 155xx, circuit services provide the following major capabilities:

•Finding all end-to-end connections between NEs in terms of client ports, provided the entire path was traversed within ONS 15530 and ONS 15540 NEs.

•Displaying the protection information associated with each circuit.

•Displaying all directional-based paths that have been configured and are in use for a protected circuit.

•Displaying the active and standby paths that have been configured and are in use for a protected circuit.

Note Circuit information is not available for the ONS 15216, ONS 15302, ONS 15501, ONS 15800, ONS 15801, ONS 15808, Cisco Catalyst 6509, Cisco 7600, or Cisco XR 12000. For the ONS 15302 and ONS 15305, circuits can be created through CEC (Configuration > ONS 15302 or ONS 15305 > Launch Cisco Edge Craft).

For ONS 15305 NE releases 3.0 and later, circuits can be created in CTM, CTC, and CEC. Circuits that are created in CTM or CTC can be managed in CTM, CTC, and CEC. But circuits that are created in CEC show unpredictable and erroneous behavior in CTM and CTC.

For ONS 15305 NE releases earlier than R3.0, the circuit information is not available in CTM. Circuits can be created in CEC but cannot be managed in CTM.

Note Circuit management performance depends on an efficient DCN network. Refer to the ONS 15454 user documentation for details.

The following table defines the circuit terms and options that are used throughout this chapter.

Table 7-1 Circuit Terms and Options

Circuit Option

Description

Link

Represents a topological relationship between two physical termination points (PTPs) for a particular layer rate. The possible set of layer rates is determined by the layer rates terminated by the PTP. For example, an OC-N port will terminate a physical layer rate and a SONET layer rate.

Circuit

Represents an end-to-end connection between two or more CTPs.

Cross-connection

A (normally flexible) connection between two CTPs within the same NE.

Link connection

An inflexible (or fixed) connection between two CTPs that are contained by two PTPs connected by a link. It represents a portion of the transport capacity of a link, such as an STS-1 channel within an OC-N link.

PTP

A termination point that is the actual or potential endpoint of a link that might be abstracted as a PTP. It is the representation of a physical port.

CTP

Represents the actual or potential endpoint of a cross-connection, link connection, or circuit. A CTP is contained within a PTP. In some cases, there is a single CTP associated with a PTP, such as with a DS-1 PTP. There could also be multiple CTPs, such as with STS-1 or STS-Nc CTPs contained within an OC-N PTP.

Source

The circuit source is where the circuit enters the network.

Destination

The circuit destination is where the circuit exits the network.

Automatic circuit routing

CTM routes the circuit automatically on the shortest available path based on routing parameters and bandwidth availability.

Manual circuit routing

Manual routing allows you to choose a specific path, not just the shortest path chosen by automatic routing. You can choose a specific STS or VT for each circuit segment for SONET nodes, or a specific VC4, VC3, or VC12 for each circuit segment for SDH nodes. You can also create circuits from work orders prepared by an OSS such as the Telcordia TIRKS system.

Low-order tunnel

Low-order tunnels allow VC3 and VC12 circuits to pass through an SDH node without using cross-connect card (XC10G and XCVXL) resources. Low-order circuits using tunnels use cross-connect capacity only at the source and destination nodes. One low-order tunnel can carry three VC3s, and each VC3 can carry 21 VC12s. One tunnel can carry one VC3 circuit span and 42 VC12 circuit spans, and each VC3 is a separate container that can contain a VC3 circuit span or 21 VC12 circuit spans.

Low-order aggregation point

Low-order aggregation points (LAPs) allow low-order VC12 and VC3 circuits to be aggregated into a VC4 for handoff to non-ONS networks or equipment, such as interoffice facilities (IOFs), switches, or digital access cross-connect systems. The VC4 grooming end of the LAP requires an STM-N card. LAPs can be created on MS-SPRings, 1-1, or unprotected nodes, but cannot be created on subnetwork connection protection (SNCP) nodes.

VT tunnel

VT tunnels allow VT1.5 circuits to pass through a SONET node without using cross-connect resources. VT circuits using VT tunnels use cross-connect capacity only at the source and destination nodes. One VT tunnel can carry 28 VT1.5 circuits.

VT aggregation point

VT aggregation points (VAPs) allow VT circuits to be aggregated into an STS for handoff to non-ONS networks or equipment, such as IOFs, switches, or digital access cross-connect systems. VAPs reduce VT matrix resource utilization at the node where the VT1.5s are aggregated onto the STS. This node is called the STS grooming end. The STS grooming end requires an OC-N, EC-1, or DS3XM-6 card. VT aggregation points can be created on BLSR, 1+1, or unprotected nodes, but cannot be created on UPSR nodes.

7.2.3  Viewing the Circuit Table

The Circuit table shows circuit information for all circuits that make up a topology. A circuit describes a fixed-size bandwidth pipe that is fully cross-connected from one user-defined source point (node, slot, or port) to a second user-defined destination point across some number of node-to-node optical spans (zero if the circuit is local to a single NE).

An endpoint can be an actual physical drop port (DS-1, DS-3, and so on) or an STS-n or VT1.5 channel in an optical line. A multicast circuit consists of circuit spans that have one source endpoint and a sequence of destination endpoints.

Figure 7-1 Circuit Table

Note See Appendix A, "Icons and Menus Displayed in CTM" for details of all the icons displayed in this window.

To launch the Circuit table, do any of the following:

For non-VCAT members, the value of this field is always N/A.

Circuit Name

Displays the name of the selected circuit.

Note If there are multiple circuits with the same name displayed in the Circuit table, the label Duplicate appears in this column.

Note If a card is upgraded or changed on an NE and an existing circuit terminates on the changed card, the Circuit table display does not reflect the new card type for the circuit until CTM next reads the circuit information from the network. You can force all circuits involved with the upgraded card in the Circuit table to update by marking the NE as Out of Service and then In Service.

Caution For TL1 circuits, if you simultaneously mark all of the NEs involved in the circuit as Out of Service, CTM loses the EMS attributes (such as circuit alias, customer ID, and service ID). If you later mark all of the NEs involved in the TL1 circuit as In Service, the circuits are discovered, but the EMS attributes remain missing. To retain EMS attributes, you must upgrade the TL1 circuits to regular CTC circuits before adding EMS attributes and marking the NEs as Out of Service. To do this, select the TL1 circuit in the Circuit table and choose Configuration > Reconfigure Circuit(s).

7.2.4  Creating Circuits Using the Circuit Wizard

The Create Circuit wizard (Configuration > Create Circuit) allows you to create circuits on CTC-based and CRS-1 NEs. Use the Create Circuit wizard to create an end-to-end circuit through a subnetwork. A subnetwork is defined as a set of NEs that are interconnected directly or indirectly through links known by CTM. CTM supports circuit provisioning across a heterogeneous network. Establish a circuit by specifying the A and Z termination points (TPs). You can create multiple circuits using the Create Circuit wizard; however, for VT tunnel circuits, the number you can create is limited by the bandwidth available on the VT tunnel being used. The maximum number of VT circuits that can be routed through a VT tunnel is 28.

Caution When adding CTC-based circuits, examine the links in the network to ensure correct operation. If any links are down, verify that the ports are not data communications channel (DCC) enabled. For information about viewing links, see 3.6.4  Viewing the Link Table, page 3-43.

Note New circuits can be created across subnetworks. To create a new circuit across subnetworks you must first disable automatic grouping of NEs in the Control Panel. See 4.4.9  Configuring Application-Specific Parameters, page 4-62 for more information.

The following table describes the launch points and the expected behavior for the Circuit wizard.

Note Low-order (LO) circuit options are not available for LO_VCAT circuits. Routing a LO_VCAT circuit, by selecting LO routing options to create a LAP/VC tunnel automatically, is not supported. If the LAP/VC tunnel already exists, and bandwidth is available, the LAP/VC tunnel is used to route LO_VCAT circuits.

Note When you create a low-order circuit and choose to create a tunnel automatically (by selecting the VT Tunnel on Transit Nodes option), the alias for the tunnel circuit will be the same as that provided for the low-order circuit. When you create multiple low-order circuits, the alias for the tunnel will be the same as the alias of the first low-order circuit.

The following table describes the fields in the Create Circuit wizard for optical devices.

Table 7-7 Field Descriptions for the Create Circuit Wizard—Optical Devices

Field

Description

Navigation Pane

The navigation pane on the left side of the Create Circuit wizard tells you where you are in the process of creating the circuit. The list of tasks shown initially is the default list of all possible tasks. As you move through the circuit creation, you are taken to the appropriate task. You can use the navigation pane to jump quickly from one task to the next, or to an already visited task.

Using the navigation pane is faster than using the Back and Next buttons, because you can jump over multiple panes in one step versus clicking Back or Next and moving through the panes sequentially.

Tip As you proceed through the wizard, the panes you have visited are highlighted in white and identified by a number. Panes that are not applicable to the current circuit creation sequence are shown in italics.

Tip Click the Maximize button to expand the Create Circuit wizard. After you expand the Create Circuit wizard, the Maximize button changes to the Reset Size button. Click the Reset Size button to reduce the Create Circuit wizard to its original size.

•IS AINS (In Service-Auto In Service)—Alarm reporting is suppressed, but the circuit is able to carry traffic.

•OOS DSBLD (Out of Service-Disabled)—The circuit is out of service and unable to carry traffic.

•OOS_MT (Out of Service-Maintenance)—The circuit is in maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit.

For SDH circuits, corresponding values are:

•Unlocked

•Unlocked,autoInService

•Locked,disabled

•Locked,maintenance

Apply to Source/Destination Ports, If Allowed

Check this check box to apply the selected state to the source and destination ports.

Trunk Filtering

(available for OCHCC circuit type only)

G.709 OTN

Disables or enables the G.709 OTN feature. Check this check box to filter the list of circuits to display only G.709 OTN-compatible circuits.

FEC

Disables or enables forward error correction.

Customer Information

Customer ID

Optional text field that displays the customer ID of the circuit. The customer ID can contain 0 to 256 alphanumeric and special characters.

Service ID

Optional text field that displays the service ID of the selected circuit. The service ID can contain 0 to 256 alphanumeric and special characters.

VCAT

Symmetric

Check this check box to create a symmetric VCAT circuit.

Member Size

Select a size for each VCAT member.

Number of Members

Specify the number of members to be configured for the VCAT circuit.

Mode

Choose the protection mode for the VCAT circuit:

•None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail.

•SW-LCAS—Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth.

•LCAS—Uses a signaling protocol where the members in a virtual concatenation group (VCG) can be dynamically changed without interrupting the operation of uninvolved members. If implemented correctly, there are no errors. LCAS allows the source and destination nodes of a VCG to signal to each other so that the addition or deletion of a member from the VCG can be synchronized without errors.

Protection

Protected

Check this check box to specify that circuit endpoints have to be selected only from cards that have embedded splitter-type protection.

Protected Drops (Non-Ethernet)

Specify whether protected drops are indicated. If selected, this option restricts the set of displayed source or destination termination points to those in 1:1, 1:n, or 1+1 protection groups.

Provision Working Go and Return on Primary Path

Check this check box to provision SNCP/UPSR protection routes in a Go and Return fashion as detailed in ITU-T G.841, to avoid too long a delay on another direction of traffic. This feature applies only to bidirectional UPSR/SNCP circuits. Unidirectional UPSR/SNCP circuits are not affected and the shortest path to the destination is always used as the working path.

Revertive

Specify whether traffic is reverted back to its original path when the conditions that diverted the circuit to the protect path are repaired. If you do not choose Revertive, traffic remains on the protect path.

Reversion Time

Specify the amount of time (in minutes) after which traffic reverts back to the original working path when conditions that caused the switch are cleared. The range is from 5.0 to 12.0 minutes. The Cisco default is 5 minutes.

SF Threshold (for SONET circuits only)

Set the UPSR path-level signal failure (SF) threshold.

Revert/Reversion Time

(For protected circuits) Select the splitter-type protection.

Routing Preferences

Route Automatically

Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. Alternately, you can disable automatic route selection and manually route the circuit where you specify all the intermediate hops on a hop-by-hop basis (up to 64 hops per circuit). You can manually route the circuit using either one of the following views:

•Graphical—Provides a map view that displays the nodes and links you can use to create the circuits. You can select the nodes and links that you need for your circuit from the map view.

•Textual—Provides a text view that lists the nodes and links you can use to create the circuits.

Note If the source and destination of the circuit are on the same node, automatic routing is enabled.

Using Required Nodes/Links

(Available only if Route Automatically is checked) If checked, CTM automatically routes the circuit through the required nodes and/or links. There are two ways you can specify the required nodes and links. Choose one of the following:

•Graphical

•Textual

Review Route Before Creation

(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

VT-DS3 Mapped Conversion

(Available only if Route Automatically is checked) If checked, you can route the circuit using the DS3XM12 card. Not applicable for data cards (ML-series and CE-100T-8 cards). VT-DS3 mapped conversion is for VAP circuits and is automatically selected while creating a VAP circuit using a DS3 port.

Time Slot Restriction

If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks.

Note Time Slot Restriction is not available for OCHCC and OCHNC circuit types.

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter in the Time Slot Restriction field cannot be identical, or circuit creation will fail with an error message.

Common Fiber Routing

(For VCAT circuits) Click this radio button to route each member circuit on the same fiber.

Split Routing

(For VCAT circuits) Click this radio button to route member circuits on separate paths.

Member Preferences

(For VCAT circuits) Specify the following information for member circuits:

•Number—Enter a number between 1 and 256 to identify the member.

•Name—Enter a unique name to identify the member. The name can contain up to 48 alphanumeric characters, including spaces.

•Protection—Specify the member circuit protection type (Fully Protected, PCA, or Unprotected).

•Node Diverse—Specify the node diversity for each member circuit:

–Required—Ensures that the primary and alternate paths are node-diverse.

–Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse.

–Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse. The paths might be node-diverse, but CTM does not check for node diversity.

•Set Protection for All—Allows you to choose the same protection type for all members.

•Set Node Diversity for All—Allows you to specify the same node diversity for all members.

Fully Protected Path

If selected, CTM ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking the Dual Ring Interconnect check box. Alternately, if the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications:

•Required—Ensures that the primary and alternate paths of the UPSR portions of the complete circuit path are node-diverse.

•Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path.

•Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.

Protection Channel Access

To route the circuit on a BLSR protection channel, if available, uncheck the Fully Protected Path check box, and check the Protection Channel Access check box.

Dual Ring Interconnect

If you selected Fully Protected Path and the circuit will be routed on a DRI, check the Dual Ring Interconnect check box.

Note For DRI and iDRI manually created circuits, you must double-click the DRI span for it to become DRI. A single-click does not enable the DRI span.

Diverse Shared Risk Link Group (SRLG)

If checked, fully protected circuits will be routed through working and protected links that do not share risk groups.

Conversion Route Constraints

(available only if VT-DS3 Mapped Conversion is checked)

NE ID

Select from the list of available NE IDs to specify the source NE ID.

Subnetwork ID

Display only. Displays the ID of the subnetwork associated with the circuit source.

Slot

Specify the source slot that contains the DS3XM12 card.

DS3 Mapped STS

Choose Circuit Source or Circuit Dest.

VT/VC LO Circuit Options

(available only for VT and VC LO path circuits)

VT/VC LO Tunnel on Transit Nodes

This option is available if the VT or VC circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VT/VC circuits to pass through NEs without consuming low-order cross-connect card resources. In general, creating tunnels is a good idea if you are creating many low-order circuits from the same source and destination.

VT Aggregation Point (VAP)/VC LO Aggregation Point (LAP)

(For SONET) This option is available if you are creating a VT1.5 circuit to a DS-1, EC-1, DS3XM-6; or an OC-N port on a BLSR, 1+1, or Unprotected node. A VAP allows VT1.5 circuits to be routed through a node using one STS connection on the cross-connect card matrix rather than multiple connections on the VT1.5 matrix.

(For SDH) This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix.

Circuit Source is STS/VC4 Grooming Node

Creates the VAP or LAP on the VT or VC circuit source node. This option is available only if the VT circuit originates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit originates on an STM-N card.

Circuit Destination is STS/VC4 Grooming Node

Creates the VAP or LAP on the VT or VC circuit destination node. This option is available only if the VT circuit terminates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit terminates on an STM-N card.

None

Choose this option if you do not want to create a low-order tunnel or a VAP/LAP. This is the only available option if CTM cannot create a low-order tunnel or VAP/LAP.

VLAN Selection

(available only for Ethernet cards or EtherGroups)

VLANs

Select from the list of available VLANs to associate an existing VLAN to the circuit. If the Circuit VLANs list is empty, CTM assigns the default VLAN.

To create a new VLAN, click the New VLAN button. Enter a unique VLAN name and ID. The VLAN ID must be an integer greater than 1 but less than 4093. Click OK; then, click OK in the Successfully created VLAN confirmation dialog box. The new VLAN appears in the list of VLANs. The list is ordered alphanumerically by VLAN name, where numbers precede letters and uppercase letters precede lowercase ones.

Note Gigabit Ethernet G-series, ML-series, and E-series cards that are configured in port ML-series mode do not support VLAN assignment.

Enable Spanning Tree

Check this check box to enable spanning tree protection for the circuit. This option is disabled for intranode and multicard Ethernet circuits.

This pane also indicates the source (and secondary source, if applicable) and destination (and secondary destination, if applicable) NEs selected for circuit creation. The map view displays information about the spans selected during autorouting in the subnetwork. The selected spans are shown in blue. When you select a span, its corresponding details are displayed in the Selected Span pane. The circuit summary displays the total hops and the cost for working and protect paths for the routed circuit.

Source NE ID

Displays the ID of the NE selected as the source node.

Destination NE ID

Displays the ID of the NE selected as the destination node.

Included Spans

If you enabled automatic route selection in the Routing Preferences pane, CTM automatically selects spans to route the circuit. This field lists all the spans that the CTM server selected automatically.

Selected Span

Displays detailed information about the span selected in the Included Spans list.

Add and Remove buttons

You can review and modify the automatic route that is selected for circuit creation. Click Add to change the automatically selected route by adding a route to the Selected Spans list. Click Remove to remove a route from the list.

This functionality is similar to manual routing, except that the route from the source to the destination is preselected.

Note You can modify the review route only for the following circuit types: STS_CIRCUIT, VT_CIRCUIT, VT_TUNNEL, VT_AGGREGATION, STS_VCAT_CIRCUIT, VT_VCAT_CIRCUIT, VC_HO_PATH_CIRCUIT, VC_LO_PATH_CIRCUIT, VC_LO_PATH_TUNNEL, VC_LO_PATH_AGGREGATION, VC_HO_VCAT_CIRCUIT, and VC_LO_VCAT_CIRCUIT.

Table 7-8 Field Descriptions for the Create Circuit Wizard—CRS-1 Devices

Field

Description

Navigation Pane

The navigation pane on the left side of the Create Circuit wizard tells you where you are in the process of creating the circuit. The list of tasks shown initially is the default list of all possible tasks. As you move through the circuit creation, you are taken to the appropriate task. You can use the navigation pane to jump quickly from one task to the next, or to an already visited task.

Using the navigation pane is faster than using the Back and Next buttons, because you can jump over multiple panes in one step versus clicking Back or Next and moving through the panes sequentially.

Tip As you proceed through the wizard, the panes you have visited are highlighted in white and identified by a number. Panes that are not applicable to the current circuit creation sequence are shown in italics.

Tip Click the Maximize button to expand the Create Circuit wizard. After you expand the Create Circuit wizard, the Maximize button changes to a Reset Size button. Click the Reset Size button to reduce the Create Circuit wizard to its original size.

7.2.4.1  Creating an STS (Including Ethernet), STS-V, VT, VT-V, VT Tunnel, or VT Aggregation Circuit

Step 1 Select the node for which to create a circuit and open the Circuit wizard. For an explanation of Circuit wizard launch points, see Table 7-5.

Step 2 In the Type pane, choose STS (including Ethernet circuits), STS-v, VT, VT-v, VT Tunnel, or VT Aggregation. (Choose STS for ML-series circuits. For ONS 15454, choose STS for circuits starting and ending at a fiber channel [FCMR] card). In the Number of Circuits field, enter the number of circuits you want to create. The Cisco default is 1. If you enter more than one, you can use autoranging to create the additional circuits automatically.

Step 3 Click Next.

Step 4 In the Attributes pane, enter the following information; then, click Next:

•Name—Enter a unique name for the new circuit. The circuit name is a free-format string of up to 48 ASCII characters.

•Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

•Description—Enter a circuit description of up to 256 characters.

•Size (STS circuits only)—Specify STS-1, STS-9c, STS-12c, STS-24c, STS-48c, STS-96c, or STS-192c. The valid size for circuits involving the DS3i card is STS-3c. Valid sizes for circuits involving the FC_MR-4 card are STS-1, STS-3c, STS-24c, and STS-48c.

For a single-card EtherSwitch, only STS-1, STS-3c, STS-6c, and STS-12c apply. For a multicard EtherSwitch, only STS-1, STS-3c, and STS-6c apply.

Valid circuit sizes for an ML-series circuit are STS-1, STS-3c, STS6c, STS-9c, STS-12c, STS-24c, and STS-96c.

•Bidirectional—Check this check box to create a two-way circuit; uncheck it to create a one-way circuit. (For STS and VT circuits only; E-series circuits, G-series circuits, ML-series circuits, VAP circuits, and VT tunnels are bidirectional.)

•Number of Circuits—Enter the number of circuits to be created. For ML-series circuits, only one circuit can be created.

•State—Choose an administrative state to apply to the circuit:

–IS—The circuit is in service.

–OOS—The circuit is out of service. Traffic is not passed on the circuit.

–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service.

–OOS-MT—The circuit is in maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit.

•Apply to source/destination ports—Check this check box to apply the selected state in the State field to the circuit source and destination ports. Uncheck this check box for ML-series circuits.

•Protected Drops (Non-Ethernet)—Check this check box if you want the circuit routed on protected drops only. If selected, this option restricts the set of displayed source or destination termination points to those in 1:1, 1:N, or 1+1 protection groups. Uncheck this check box for ML-series circuits.

•Provision working go and return on primary path (bidirectional UPSR/SNCP protection only)—Check this check box to provision the working path to go or return to the primary path.

Note CTM currently provisions unidirectional SNCP/UPSR circuits following the GR-1400 standard. For bidirectional SNCP/UPSR circuits, you can check the Provision working go and return on primary path check box to route the working and protect paths in one direction following the ITU-T G.841 standard. Unidirectional UPSR/SNCP circuits are not affected by this new routing, and the shortest path is always used as the working path.

•Path Selectors (UPSR protection only)—If the circuit will be routed on a UPSR, set the UPSR path selectors as follows:

–Revertive—Check this check box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If you do not choose Revertive, traffic remains on the protect path.

–Reversion Time—If Revertive is checked, specify the amount of time (in minutes) after which traffic reverts back to the original working path when the conditions that caused the switch are cleared.

–SF Threshold (for STS circuits only)—Set the UPSR path-level SF bit error rate (BER) threshold. This field is visible only for point-to-point topologies.

–SD Threshold (for STS circuits only)—Set the UPSR path-level SD BER threshold. This field is visible only for point-to-point topologies.

–Switch on PDI-P (for STS circuits only)—Specify whether or not traffic should switch based on a received STS payload defect indication. This field is visible only for point-to-point topologies.

•(Optional) Specify the customer information:

Step 5 In the Source pane, enter the following information; then, click Next:

•NE ID—Select from the list of available TPs to specify the source TP.

•Source—Specify the source slot, port, STS, DS1-14, and VT.

•Use Secondary Source—Check this check box to create a secondary source. Then, specify the NE ID, slot, port, STS, DS1-14, and VT for the secondary source.

Note The secondary source is applied to open-ended UPSR and DRI.

Step 6 In the Destination pane, enter the following information; then, click Next:

•NE ID—Select from the list of available TPs to specify the destination TP.

•Destination—Specify the destination slot, port, STS, DS1-14, and VT.

•Use Secondary Destination—Check this check box to create a secondary destination. Then, specify the slot, port, STS, DS1-14, and VT for the secondary destination.

Note The secondary destination is applied to open-ended UPSR and DRI.

Step 7 In the VLAN Selection pane (available only if an E-series Ethernet card or EtherGroup is chosen as the source or destination slot), complete the following substeps; then, click Next:

a. Select from the list of available VLANs to associate an existing VLAN to the circuit. If the Circuit VLANs list is empty, CTM assigns the default VLAN.

Note Gigabit Ethernet G-series, ML-series, and E-series cards that are configured in Port Mapped mode do not support VLAN assignment.

b. To create a new VLAN, click the New VLAN button. Enter a unique VLAN name and ID. The VLAN ID must be an integer greater than 1 but less than 4093. Click OK; then, click OK in the Successfully created VLAN confirmation dialog box. The new VLAN appears in the list of VLANs. The list is arranged alphanumerically by VLAN name, where numbers precede letters and uppercase letters precede lowercase ones.

c. Check the Enable Spanning Tree check box to enable spanning tree protection for the circuit. This option is disabled for intranode and multicard Ethernet circuits.

Step 8 In the Routing Preferences pane, complete the following substeps; then, click Next.

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. VT-DS3 Mapped Conversion—(Available only if Route Automatically is checked) If checked, you can route the circuit using the DS3XM12 card. Not applicable for data cards (ML-series and CE-100T-8 cards). VT-DS3 mapped conversion is for VAP circuits and is automatically selected while creating a VAP circuit using a DS3 port.

e. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM uses to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks.

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter in the Time Slot Restriction field cannot be identical or circuit creation will fail with an error message.

f. Fully Protected Path—If not selected, choose Protection Channel Access to route the circuit on a BLSR protection channel.

g. Fully Protected Path—If selected, CTM ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking Dual Ring Interconnect. Alternately, if the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications:

•Required—CTM ensures that the primary and alternate paths within the UPSR portions of the complete circuit path are node-diverse.

•Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path.

•Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.

•Dual Ring Interconnect—If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

Step 9 In the VT Options pane (available only if you are creating a VT circuit and automatic routing is selected), choose one of the following radio buttons; then, click Next:

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM uses to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks.

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Member Preferences table > Time Slot Restriction field. The STS/VC4 values that you enter in the Time Slot Restriction field cannot be identical, or circuit creation will fail with an error message.

e. Select the routing preference for VCAT members. If all members are to be routed on a single fiber, choose Common Fiber Routing. If members are to be routed through different fibers in case one fiber does not have sufficient bandwidth, choose Split Routing.

f. Specify the following member preferences:

•Number—Select the member number, a unique number from 1 to 256.

•Name—Edit the name for the member circuit. By default, <VCAT_NAME>_<Default MemberNumber> is the member name, where <VCAT_NAME> is the parent VCAT circuit name being created.

•Protection—Select the protection mechanism for member circuits. To route the circuit on a protected path, choose Fully Protected (default). A fully protected circuit route is created based on the diversity option you choose. Fully protected paths might or might not have UPSR/SNCP path segments with primary and alternate paths. The path diversity options apply only to UPSR/SNCP path segments, if any exist. To create an unprotected circuit, choose Unprotected.

•Node Diversity—Select node diversity for each member circuit.

g. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended UPSR/SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended UPSR/SNCP mesh network portion of the complete circuit path.

•Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended UPSR/SNCP mesh network portions of the complete circuit path are needed.

•N/A (Not Applicable)—Dual Ring Interconnect is not supported from CTM.

7.2.4.3  Creating a VC_HO_Path_Circuit

The E1-N-14 card, STM-N cards, and Ethernet cards all use high-order path circuits. You can create unidirectional or bidirectional, revertive or nonrevertive, high-order path circuits. CTM can route the circuits automatically, or you can route them manually. The E3-12 and DS3i-N-12 cards use VC low-order path tunnels.

Step 1 Select the node for which to create a circuit and open the Circuit wizard. For an explanation of Circuit wizard launch points, see Table 7-5.

Step 2 In the Type pane, choose VC_HO_Path_Circuit. The circuit type determines the provisioning options that are displayed. In the Number of Circuits field, enter the number of circuits you want to create. The Cisco default is 1. If you enter more than one, you can use autoranging to create the additional circuits automatically.

Step 3 Click Next.

Step 4 In the Attributes pane, enter the following information; then, click Next:

•Name—Enter a unique name for the new circuit. The circuit name is a free-format string of up to 48 ASCII characters.

•Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

•Description—Enter a circuit description of up to 256 characters.

•Size—Select the circuit size. VC high-order path circuits can be VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-16c, or VC4-64c for optical cards and for some Ethernet cards (depending on the card type). Of the Ethernet cards, only the G-1000 can use VC4-3c, VC4-8c, and VC4-16c. The "c" indicates concatenated VC4s.

•Bidirectional—Check this check box to create a two-way circuit; uncheck it to create a one-way circuit.

•State—Specify the circuit state. Options vary depending on the type of circuit selected.

•Apply to source/destination ports—Check this check box to apply the selected state to the source and destination ports.

•Protected Drops—Check this check box if you want the circuit routed to protected drops only; that is, to cards that are in 1:1, 1:N, or 1+1 protection.

•Provision working go and return on primary path (bidirectional UPSR/SNCP protection only)—Check this check box to provision the working path to go and return to the primary path.

Note CTM currently provisions unidirectional SNCP/UPSR circuits following the GR-1400 standard. For bidirectional SNCP/UPSR circuits, you can check the Provision working go and return on primary path check box to route the working and protect paths in one direction following the ITU-T G.841 standard. Unidirectional UPSR/SNCP circuits are not affected by this new routing, and the shortest path is always used as the working path.

•SNCP path selector defaults—If the circuit will be routed on an SNCP, set the defaults as follows:

–Revertive—Check this check box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If Revertive is not chosen, traffic remains on the protect path.

–Reversion time—If Revertive is checked, set the reversion time. This is the amount of time that elapses before the traffic reverts to the working path. Traffic can revert when conditions causing the switch are cleared. (The Cisco default reversion time is 5 minutes.)

–SF threshold—Choose from 1 E-3, 1 E-4, or 1 E-5.

–SD threshold—Choose from 1 E-5, 1 E-6, 1 E-7, 1 E-8, or 1 E-9.

–Switch on PDI-P—Not applicable.

•Customer ID (optional)—Identify the end user of the circuit.

•Service ID (optional)—Enter the service ID of the circuit.

Step 5 In the Source pane, set the circuit source. The options displayed depend on the circuit type, the circuit properties selected in the Attributes pane, and the cards installed in the node. Click Use Secondary Source if you want to create an SNCP bridge/selector circuit entry point in a multivendor SNCP.

Step 6 Click Next.

Step 7 In the Destination pane, set the circuit destination. The options displayed depend on the circuit type, the circuit properties selected in the Attributes pane, and the cards installed in the node. Click Use Secondary Destination if you want to create a circuit destination point for unidirectional/bidirectional circuits.

Step 8 Click Next.

Step 9 In the Routing Preferences pane, complete the following substeps; then, click Next:

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM uses to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks.

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Member Preferences table > Time Slot Restriction field. The STS/VC4 values that you enter in the Time Slot Restriction field cannot be identical, or circuit creation will fail with an error message.

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 10.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 10.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended SNCP mesh network portion of the complete circuit path.

•Don't Care: Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended SNCP mesh network portions of the complete circuit path are needed.

•Dual Ring Interconnect—Provisions the circuit in a DRI topology. If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

7.2.4.9  Creating a DWDM OCHCC—CRS-1

CTM allows you to create OCHCC circuits between two CRS-1 or ONS 15454 MSTP products. ONS 15454 MSTP is a DWDM optical product designed to provide transparent, reliable, and manageable transport capacity to Cisco Metro optical products such as ONS 15454 MSPP, ONS 15530, and ONS 15540. OCHCC increases ONS 15454 MSTP platform functionalities, allowing you to create a new end-to-end circuit layer with transponder/muxponder client ports or ITU-T line card trunk ports as endpoints.

OCHCC can be created in a peer-to-peer setup, where the trunk ports are directly connected by a routable virtual link, or in an MSTP setup, where the circuit is routed through a tunnel circuit, which is created between the trunk ports (OCH trail tunnel), and which in practice contains an OCHNC-type circuit.

OCHCC circuit creation is supported on CRS-1 NEs with ITU Physical Layer Interface Modules (PLIMs) on 10 GE C-band and OC768 interfaces. OCHCC circuit creation between CRS-1 NEs is supported in the following scenarios:

•Trunk ports of CRS-1 peers pass through an ONS 15454 MSTP and the PLIM TXP card is connected to the ONS 15454 MSTP through two manually routable unidirectional physical links at 10G-ITU layer rate. One unidirectional link is from the CRS-1 trunk port to the ONS 15454 MSTP DEMUX card port; the other unidirectional link is from the ONS 15454 MSTP MUX card port to the same trunk port on the CRS-1.

If there is more than one ONS 15454 MSTP NE connection between CRS-1 peers, an OCHNC circuit is created automatically between the ONS 15454 MTSP NEs. The following figure shows a graphical representation of this scenario.

Figure 7-2 CRS-1 DWDM OCHCC Circuit Creation—Scenario 1

•Trunk ports of CRS-1 peers do not pass through an ONS 15454 MSTP and the PLIM cards are directly connected to the trunk ports of the CRS-1 NEs. The following figure shows a graphical representation of this scenario.

7.2.4.11  Creating a Monitor Circuit—CTC-Based NEs

Use the Create Monitor Circuit wizard to create a new monitor circuit on CTC-based NEs.

Note A monitor circuit's alias is based on the alias of the original circuit. CTM does not generate unique numbers; therefore, two monitor circuits created on the same circuit will have the same alias, while their names will be different (including two unique numbers appended in the network).

Step 1 Select the CTC-based NE where you want to create a monitor circuit and open the Circuit table. For an explanation of Circuit table launch points, see Table 7-2.

Step 2 In the Circuit table, select the bidirectional circuit to be monitored.

Step 3 Choose Configuration > Modify Circuit (or click the Modify tool). The Modify Circuit dialog box opens.

Step 4 In the Modify Circuit dialog box, click the Monitor tab. The Monitor tab displays the ports that can be used to monitor the circuit selected in Step 2.

If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM uses to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks.

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Member Preferences table > Time Slot Restriction field. The STS/VC4 values that you enter in the Time Slot Restriction field cannot be identical, or circuit creation will fail with an error message.

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 10.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 10.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended SNCP mesh network portion of the complete circuit path.

•Don't Care: Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended SNCP mesh network portions of the complete circuit path are needed.

•Dual Ring Interconnect—Provisions the circuit in a DRI topology. If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

Step 10 In the Modify Circuit dialog box, click Close.

7.2.4.13  Creating G1000-4 Circuits

This section explains how to provision G1000-4 point-to-point circuits and Ethernet manual cross-connects. Ethernet manual cross-connects allow you to cross-connect individual Ethernet circuits to an STS channel on the ONS 15454 SONET or ONS 15454 SDH optical interface and to bridge non-ONS SONET network segments.

7.2.4.13.1  G1000-4 Point-to-Point Ethernet Circuits

G1000-4 cards support point-to-point circuit configuration. Provisionable circuit sizes are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c. Each Ethernet port maps to a unique STS circuit on the SONET side of the G1000-4.

The G1000-4 card supports any combination of up to four circuits from the list of valid circuit sizes; however, the circuit sizes can add up to no more than 48 STSs. Due to hardware constraints, the initial release of the G1000-4 card (software release 3.2) imposes additional restrictions on the combinations of circuits that can be dropped onto a G1000-4 card. These restrictions are transparently enforced by the ONS 15454 SONET and ONS 15454 SDH, so there is no need to keep track of restricted circuit combinations.

•The restriction occurs when a single STS-24c is dropped on a card. In this instance, the remaining circuits on that card can be another single STS-24c or any combination of circuits of STS-12c size or smaller that add up to no more than 12 STSs (that is, a total of 36 STSs on the card).

•No circuit restrictions are present if STS-24c circuits are not being dropped on the card. The full 48 STSs of bandwidth can be used (for example, a single STS-48c circuit or 4 STS-12c circuits).

•Since the restrictions apply only when STS-24c circuits are involved but do not apply when two STS-24c circuits are on the same card, the impact of these restrictions can be easily minimized. Group the STS-24c circuits together on a card separate from circuits of other sizes. The grouped circuits can be dropped onto other G1000-4 cards on the ONS 15454 SONET or ONS 15454 SDH. The G1000-4 uses STS cross-connects only. No VT-level cross-connects are used. All SONET-side STS circuits must be contiguous.

Caution G1000-4 circuits connect with OC-N cards or other G1000-4 cards. G1000-4 cards do not connect with E-series Ethernet cards.

Caution The G1000-4 card requires the XC10G card to operate. The G1000-4 card is not compatible with XC or XCVT cards.

Step 1 In the Domain Explorer, select the ONS 15454 SONET or ONS 15454 SDH NE to use as one of the Ethernet circuit endpoints.

Step 2 Complete the following in the Domain Explorer:

a. Select the source circuit.

b. Choose Configuration > Create Circuit.

c. Select the destination circuit. The Create Circuit wizard opens.

Step 3 From the Type field, choose STS; then, click Next. The Attributes pane opens.

Note The VT and VT Tunnel types do not apply to Ethernet circuits.

Step 4 In the Name field, enter a name for the circuit.

Step 5 In the Circuit Alias field, enter a unique alias name for the circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

Step 6 From the Size field, choose the size of the circuit. The valid circuit sizes for a G1000-4 circuit are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c.

Step 7 Verify that the Bidirectional check box is checked.

Note The states of the Number of Circuits check box and the Protected Drops check box are provided.

Caution If provisioning a G1000-4 circuit on a UPSR, do not check the Switch on PDI-P check box. Checking the Switch on PDI-P check box might cause unnecessary UPSR protection switches.

Step 8 (Optional) Specify the customer information:

•Customer ID

•Service ID

Step 9 Click Next.

Step 10 In the Source pane, choose the circuit source node. Either end node can be the circuit source.

Step 11 From the Slot field, choose the slot containing the G1000-4 card to use as one end of the point-to-point circuit.

Step 12 In the Port field, choose a port.

Step 13 Click Next.

Step 14 In the Destination pane, choose the circuit destination node.

Step 15 In the Slot field, choose the slot containing the G1000-4 card to use as the other end of the point-to-point circuit.

Step 16 From the Port field, choose a port.

Step 17 Click Next. The Routing Preferences pane opens.

Step 18 In the Routing Preferences pane, complete the following substeps; then, click Next:

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM uses to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks.

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Member Preferences table > Time Slot Restriction field. The STS/VC4 values that you enter in the Time Slot Restriction field cannot be identical, or circuit creation will fail with an error message.

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 19.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 19.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended SNCP mesh network portion of the complete circuit path.

•Don't Care: Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended SNCP mesh network portions of the complete circuit path are needed.

•Dual Ring Interconnect—Provisions the circuit in a DRI topology. If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

Step 19 In the Manual Provisioning pane (available when Route Automatically is unchecked and the Graphical radio button is selected), do the following; then, click Next:

a. Use the map view to manually route the circuit from the source to the destination specified by the addition of the links selected. Use the right-click menu options to navigate within the map view:

7.2.4.13.2  G1000-4 Manual Cross-Connects

ONS 15454 SONET and ONS 15454 SDH NEs require end-to-end CTC visibility between nodes for normal provisioning of Ethernet circuits. When equipment from other vendors is placed between the ONS 15454 SONET and ONS 15454 SDH, equipment based on Open System Interconnection/Target Identifier Address Resolution Protocol (OSI/TARP) does not allow tunneling of the ONS 15454 SONET or ONS 15454 SDH TCP/IP-based data communications channel (DCC). To circumvent a lack of continuous DCC, the Ethernet circuit must be manually cross-connected to an STS channel riding through the non-ONS network. This allows an Ethernet circuit to run from ONS node to ONS node while utilizing the non-ONS network.

Note In this chapter, cross-connect and circuit have the following meanings: Cross-connect refers to the connections that occur within a single ONS 15454 SONET or ONS 15454 SDH to allow a circuit to enter and exit an ONS 15454 SONET or ONS 15454 SDH. Circuit refers to the series of connections from a traffic source (where traffic enters the ONS 15454 SONET or ONS 15454 SDH network) to the drop or destination (where traffic exits an ONS 15454 SONET or ONS 15454 SDH network).

Step 1 In the Domain Explorer, select the ONS 15454 SONET and ONS 15454 SDH Ethernet circuit endpoint nodes.

Step 2 Complete the following in the Domain Explorer:

a. Select the source circuit.

b. Choose Configuration > Create Circuit.

c. Select the destination circuit. The Create Circuit wizard opens.

Step 3 From the Type field, choose STS; then, click Next. The Attributes pane opens.

Note The VT and VT Tunnel types do not apply to Ethernet circuits.

Step 4 In the Name field, enter a name for the circuit.

Step 5 In the Circuit Alias field, enter a unique alias name for the circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

Step 6 From the Size field, choose the size of the circuit. The valid circuit sizes for a G1000-4 circuit are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c.

Step 7 Verify that the Bidirectional check box is checked.

Step 8 (Optional) Specify the customer information:

•Customer ID

•Service ID

Step 9 Click Next.

Step 10 In the Source pane, choose the circuit source node.

Step 11 From the Slot field, choose the slot containing the Ethernet card.

Step 12 From the Port field, choose a port.

Step 13 Click Next.

Step 14 In the Destination pane, choose the current node as the circuit destination.

Step 15 From the Slot field, choose the optical card that will carry the circuit.

Step 16 Choose the STS that will carry the circuit from the STS field; then, click Next. The Routing Preferences pane opens.

Note For Ethernet manual cross-connects, the same ONS 15454 SONET or ONS 15454 SDH serves as both source and destination.

Step 17 In the Routing Preferences pane, complete the following substeps; then, click Next:

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM uses to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks.

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Member Preferences table > Time Slot Restriction field. The STS/VC4 values that you enter in the Time Slot Restriction field cannot be identical, or circuit creation will fail with an error message.

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 18.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 18.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended SNCP mesh network portion of the complete circuit path.

•Don't Care: Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended SNCP mesh network portions of the complete circuit path are needed.

•Dual Ring Interconnect—Provisions the circuit in a DRI topology. If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

Step 18 In the Manual Provisioning pane (available when Route Automatically is unchecked and the Graphical radio button is selected), do the following; then, click Next:

a. Use the map view to manually route the circuit from the source to the destination specified by the addition of the links selected. Use the right-click menu options to navigate within the map view:

•Find Node—Opens the Find Node dialog box, which lists all of the nodes displayed on the map view. Select a node from the drop-down list and click OK. The selection context in the map view changes to show the selected node highlighted in the visible map area.

•Zoom In—Allows you to zoom in on an object in the map view.

•Zoom Out—Allows you to zoom out on the map view.

•Reset Zoom—Resets the current zoom level to the default.

•Add—Allows you to add the selected span. Right-click a link and choose Add in the right-click menu. The selected link is added to the Available Spans list. The Add option applies to manual provisioning across all circuit types.

b. In the VCAT Member Number list box, select the member for which the route is to be selected.

c. In the circuit display, select the span to use for the next hop.

d. In the Available Spans area, complete the following information:
