Provisioning Services and Connections

This topic describes how to use Cisco Prime Optical to provision network services. It also explains the tasks required to create new connections, and display, modify, and delete existing connections.

This topic includes the following information:

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.

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

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.

Prime Optical allows you to create unidirectional and bidirectional circuits for CTC-based NEs. For unidirectional path switched ring (UPSR) circuits, you can create revertive or nonrevertive circuits. Prime Optical can route the circuits automatically, or you can route them manually.

You can access the Circuit Table from the Domain Explorer > Configuration > Circuit Report > Circuit Table. The selected circuit’s Circuit Table is displayed.

Note Circuit information is not available for the ONS 15216. For the ONS 15305, circuits can be created through CEC (Configuration > ONS 15305 > Launch Cisco Edge Craft).

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

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

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

Table 7-1 defines the circuit terms and options that are used throughout this topic.

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	Prime Optical 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.

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.

Note See Icons and Menus Displayed in Prime Optical for details of all the icons displayed in this window.

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

Select a node in the Domain Explorer tree and choose Configuration > CTC-Based SONET NEs or CTC-Based SDH NEs > Circuit Table .
(For CTC-based NEs) Open the Layer 2 Topology table and choose Configuration > Circuits .
Select a NE or Rack or Shelf or Slot in the Network Explorer and choose Configuration > Circuit Table .

Note When launching the Circuit Table in a large or high-end network setup and on a larger scope (for example, for the Domain Explorer), a database timeout can occur due to the high volume of data being retrieved. As a workaround, launch the Circuit Table on a smaller scope.

Table 7-2 describes the fields in the Circuit table.

Circuit Status	Displays the status of the selected optical circuit: Discovered—The circuit is completely configured in the network; all components are in place and a complete path exists from the circuit source to the circuit destination. Partial—The circuit is not complete; one or more cross-connections are not in place or one of the spans is missing. Creating—Prime Optical is creating the circuit. Deleting—Prime Optical is deleting the circuit. Discovered_TL1—A TL1-created circuit or a TL1-like Prime Optical-created circuit is complete and has upgradable cross-connects. A complete path from source to destination(s) exists. Partial_TL1—A TL1-created circuit or a TL1-like Prime Optical-created circuit with upgradable cross-connects is missing a cross-connect, and a complete path from source to destination(s) does not exist. The circuit cannot be upgraded until the missing cross-connects are in place. Partial (Split)—The circuit involves NEs that belongs to different network partitions and cannot be fully discovered by Prime Optical.
Circuit Service State	The Circuit Service State is an aggregate of the cross-connect states within the circuit. SONET, SDH, and DWDM circuits have different values. For SONET circuits, values are: In Service (IS)—All cross-connects in a circuit are in the In Service and Normal (IS-NR) service state. Out of Service (OOS)—All cross-connects in a circuit are in an Out of Service (OOS) service state, such as Out of Service and Management, Maintenance (OOS-MA,MT); Out of Service and Management, Disabled (OOS-MA,DSBLD); or Out of Service and Autonomous, Automatic In Service (OOS-AU,AINS). OOS-PARTIAL—PARTIAL is appended to the OOS circuit service state when circuit cross-connect states are mixed and not all in IS-NR. The OOS-PARTIAL state can occur during automatic or manual transitions between states. For example, OOS-PARTIAL appears if you assign the IS,AINS administrative state to a circuit with DS-1 or DS3XM cards as the source or destination. Some cross-connects transition to the IS-NR service state, while others transition to OOS-AU,AINS. OOS-PARTIAL can appear during a manual transition caused by an abnormal event such as a CTC crash or communication error, or if one of the cross-connects could not be changed. The OOS-PARTIAL circuit state does not apply to OCHNC circuit types. For SDH circuits, values are: Unlocked—All cross-connects in a circuit are in the Unlocked-enabled service state. Locked—All cross-connects in a circuit are in a Locked state (such as Locked-enabled,maintenance; Unlocked-disabled,automaticInService; or Locked-enabled,disabled). Locked-partial—Partial is appended to the Locked circuit service state when circuit cross-connect states are mixed and not all in the Unlocked-enabled service state. The Locked-partial state can occur during automatic or manual transitions between states. The Locked-partial service state can appear during a manual transition caused by an abnormal event such as a CTC crash or communication error, or if one of the cross-connects could not be changed. The Locked-partial circuit state does not apply to OCHNC circuit types.
Circuit Service State (continued)	For DWDM circuits, OCHCCs, OCH trails, and OCHNCs occupy three different optical layers. Each OCH circuit has its own administrative and service states: The OCHCC service state is the sum of the OCHCC service state and the OCH trail service state. When creating an OCHCC circuit, you can specify an initial state for both the OCHCC and the OCH trail layers, including the source and destination port states. The ANSI/ETSI administrative states for the OCHCC circuits and connections are: – IS/Unlocked – IS,AINS/Unlocked,AutomaticInService – OOS,DSBLD/Locked,disabled OCH trail ANSI/ETSI administrative states include: – IS/Unlocked – IS,AINS/Unlocked,automaticInService – OOS,DSBLD/Locked,disabled The OCHNC circuit states are not linked to the OCHCC circuit states. The administrative states for the OCHNC circuit layer are: – IS,AINS/Unlocked,AutomaticInService – OOS,DSBLD/Locked,disabled
Is Monitor	A value of True means that the circuit is a monitor circuit. A value of False means that the circuit is not a monitor circuit.
Circuit Protection Type	Indicates the circuit protection scheme. Values are: 2F BLSR—The circuit is protected by a 2-fiber bidirectional line switch ring (BLSR). 4F BLSR—The circuit is protected by a 4-fiber BLSR. BLSR—The circuit is protected by both 2-fiber and 4-fiber BLSR. UPSR—The circuit is protected by UPSR. DRI—The circuit is protected by a UPSR dual ring interconnection (DRI). 1+1—The circuit is protected by a 1+1 protection group. Y-Cable—The circuit is protected by a transponder or muxponder card Y-cable protection group. Protected—The circuit is protected by diverse SONET topologies; for example, a BLSR and a UPSR, or a UPSR and 1+1. Unprotected—The circuit is not protected. 2F-PCA—The circuit is routed on a protection channel access (PCA) path on a 2-fiber BLSR. PCA circuits are unprotected. 4F-PCA—The circuit is routed on a PCA path on a 4-fiber BLSR. PCA circuits are unprotected. PCA—The circuit is routed on a PCA path on both 2-fiber and 4-fiber BLSRs. PCA circuits are unprotected. SPLITTER—The circuit is protected by a splitter protected transponder (TXPP_MR_2.5G or 2.5G_DMP). Unknown—Circuit protection types appear in the Circuit Protection Type column of the Circuit table when the circuit status is Discovered. If the circuit is not discovered, the protection type is Unknown . Lost—The circuit was protected, but the protection has been lost due to changes in the network.
Description	Displays a description of the selected circuit.
No. of VLANs	Displays the number of VLANs associated with the circuit.
No. of SPANs	Displays the number of spans for each contiguous concatenation (CCAT) circuit. For VCAT circuits, N/A is displayed. You must launch the member table for the parent VCAT to see the number of spans per member VCAT.
Is VCAT or Member Circuit	A value of True means that the circuit is a VCAT circuit. A value of False means that the circuit is a normal CCAT circuit.
OCHNC Wavelength	Indicates the wavelength provisioned for the OCHNC, in nanometers (nm). The units are determined as follows: wavelength (nm) frequency (GHz)
OCHNC Direction	Indicates the direction of the OCHNC. Values are east-to-west, west-to-east, or N/A.
VCAT Member State	For VCAT members, indicates whether the members are enabled and active or temporarily disabled. When VCAT members are enabled and active, the value is In Group. If any of the members are disabled temporarily, the value changes to Out of Group. For non-VCAT members, the value of this field is always N/A.
Circuit Alias Name	Displays the alias name of the circuit.
Restoration Status	Indicates the status of the circuit. Values are: None—Circuit does not have any active restoration facility. Note A value of “None” does not indicate that the circuit is not restorable. Restoring—Circuit is restoring and the system is searching for a new optical path. Restored—Circuit has been successfully restored and a new optical path has been found for the circuit. Failed—Restoration facility has failed to retrieve a new optical path for the circuit. Restored and Revertible—Circuit has been successfully restored and can be reverted to the original optical path by a specific user action. Note The Restored and Revertible status can be reached only if the revert option value is Manual.

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 Prime Optical 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, Prime Optical 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).

Note Circuit names are obtained from:

The source NE (for circuits created in Prime Optical or CTC)
Cross-connection names (for circuits created via TL1, or if the source NE is not discovered)

However, some NE versions do not support cross-connection names. For these NEs, circuits created in CTC are always discovered with the name “Unknown” in Prime Optical. Also, if the source NE is not connected, and if the only NEs available in Prime Optical are those NE versions that do not support cross-connection names, circuits created with CTC or Prime Optical have the name “Unknown” until the source NE is discovered.

Creating Circuits Using the Circuit Wizard

The Create Circuit wizard ( Configuration > Create Circuit ) allows you to create circuits on CTC-based 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 Prime Optical. Prime Optical 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 Filtering the Link Table.

Note You can create new circuits across subnetworks. To do so, you must first disable automatic grouping of NEs in the Control Panel. See Configuring Application-Specific Parameters for more information.

Note In earlier CTM releases, circuit creation failed if you tried to use automatic routing to create a circuit with 20 or more spans. In CTM R9.1 and later, you can use SQL to configure the circuit-autorouting-creation-timeout property in the Prime Optical database. This property increases the reply timeout for CORBA requests when you use automatic routing to create a complex circuit that uses 20 or more spans. You cannot configure the circuit-autorouting-creation-timeout property in the Prime Optical GUI; rather, you must use SQL to configure the value in the CTM_CONFIG_TABLE in the Prime Optical database. The range is from 0 to 600 seconds; the default is 150 seconds. Note that you can configure the value as high as 2,147,483,647 seconds; however, Prime Optical considers anything higher than 600 seconds as invalid. Also, a value of 0 (zero) indicates no timeout (or an instantaneous reply from the server), which is impossible in an actual application. Therefore, Prime Optical ignores a zero value or anything higher than 600 seconds and uses the default value of 150 seconds instead. Configuring the circuit-autorouting-creation-timeout property is helpful in large, complex network topologies when circuits involve 20 or more spans. For more information, see the Cisco Prime Optical Database Schema.

Prime Optical 10.6 supports the new functionality in launching the Create Circuit wizard. Choose Configuration > Create Circuit displays the following options:

Create DWDM circuit—creates a DWDM circuit
Create SONET/SDH circuit—creates a SONET/SDH circuit

Note If the Esc key is pressed while the plus symbol is enabled, the operation is canceled and the plus symbol returns to a pointer.

Note • Alien Wavelength (AWL) and FEC provisioning functionality is available on Circuit Wizard Panel and only for UNI circuits (VTXP- to-VTXP, VTXP-to-DWDM).

AWL provisioning functionality is available on Domain Explorer and also from Network Map .
AWL provisioning will apply only on CRS end (CRS node and corresponding peer node) means in case of VTXP-to-DWDM UNI circuit, AWL provisioning will not apply at the DWDM end.

For more information on Creating DWDM circuits, see Creating, Editing or Prerouting a DWDM Circuit. For information on Creating SONET/SDH circuits, see Creating SONET/SDH Circuits.

The Create Alien Wavelength pane opens with provisioned Alien Wavelength and FEC values on Source and Destination peer node.

To change the provisioned AWL or FEC values on CRS and peer node:

a. Edit the supported Alien Wavelength and FEC values: Disabled, Standard, 20% High Gain FEC, and 7% High Gain FEC.

b. Click OK . A Cisco Prime Optical Confirmation dialog box opens to apply changes, Click Yes.

Note

If any mismatch is found in the provisioned AWL and FEC values, the system displays Cisco Prime Optical Confirmation dialog box to fix the mismatch values. Click Yes.
The system displays the Cisco Prime Optical Message dialog box, to ensure the configured message, click OK.
If no mismatch is found in the AWL and FEC values, the system displays Cisco Prime Optical Message dialog message box, click OK.

Click Create or Preroute button to provision the circuit.

– The system validates the provisioned AWL and FEC value on CRS and Peer Node (both Source and Destination in case of CRS-to-CRS UNI circuit). If any mismatch is found, the system displays the Cisco Prime Optical Confirmation dialog box to fix it, Click Yes.

The Create Alien Wavelength pane opens with provisioned AWL or FEC on peer node.
Click OK . User can change the provisioned AWL or FEC value on CRS and peer node. Refer a and the circuit provision starts.
Click No . The system stops the user to provision the circuit.

Step 13 In the WSON Attributes pane (displayed only for WSON), enter the following:

UNI Interface—Check the UNI Interface check box to configure the GMPLS UNI circuit between the ONS and CRS nodes on a DWDM node.

Note UNI circuits can be created either by using the CRS nodes or by using both the ONS and CRS nodes. But the source TP must always be the CRS node.

For UNI circuits in 10.6 NE, the Circuit Wizard allows you to choose between Manual or Automatic revert. However, circuit creation fails if the UNI link is not configured properly. If you choose Manual revert operation, and if the UNI link is not configured properly, then the following error is displayed:

Label—Enter/edit the name to display the circuit label. The label is a unique circuit identifier that is defined during circuit creation. WSON checks the label during circuit creation and restores its unique value along the path. Two identical strings can co-exist if the referred circuits do not use the same span. The label is also reported as an alphanumeric string in the circuit alarm.
Validation—Sets the validation mode. The available modes are:

– Full—The circuit gets created only if the circuit validation result is greater than or equal to the acceptance threshold value.

– None—The circuit is created without considering the acceptance threshold value.

Note You can set or edit the optical validation values for the main and the restoration path from the Create or Edit DWDM circuit window.

Allow Regeneration—Allows the Control Panel to find a regenerator deployed in the network. The regenerators are used when an optical LSP between two endpoints is not optical or lambda feasible with a single DWDM channel.

Allow regeneration check box when selected WSON circuits are allowed to traverse regeneration group and can potentially change wavelength.

Circuit Diversity—Sets the diversity path for the circuit. An existing circuit that is selected from the circuit pane is used as reference for the circuit diversity. This diverse path that will not be taken by the new circuit is displayed in the circuit pane. When selected, user can specify a circuit as diversity path option for the current circuit to be provisioned, the circuit is specified by name. Hints are displayed upon CTRL+SPACE key press or user can type a circuit name.
Ignore Path Alarms—Ignores the alarms on the path and create the circuit.
Restore—Restores the default values. Selects the priority level for the circuit. The priority is used in resolving resource allocation when two or more circuits require the same resource during circuit creation or restoration concurrently. The priority levels are 0 (High) to 7 (Low).

The Revert option reverts the circuit from the restored path to the original path after the failure is fixed. Options are:

– Automatic—Automatically reverts the circuit from the restored path to the original path after the failure is fixed, WSON alarms are acknowledged, and the soak time expires.

– Manual—Manually reverts the circuit from the restored path to the original path after the failure is fixed, the WSON alarms are acknowledged, and the soak time expires.

– Soak Time—The soak time (in hours, minutes, and seconds) is the period that the circuit on the restored path waits before switching to the original path after the failure is fixed. The circuit can revert to the original path after the soak time expires. The minimum value of soak time must be 00:00:01.

The Inherit option inherits the validation and acceptance threshold values from the primary circuit. When validation is selected, quality for working and protected path can be configured (if circuit is protected, the threshold can be applied to protected path too). The possible values are Green, Yellow, Orange and Red. See Table 7-4 for more information on the color definitions.

Note You can set/edit the optical validation values for the main and the restoration path from the Create/Edit DWDM circuit window.

Table 7-4 Color Definition Descriptions
Color	Definition
Green	Indicates that the channel failure risk is 0%.
Yellow	Indicates that the channel failure risk is between 0% and 16%.
Orange	Indicates that the channel failure risk is between 16% and 50%.
Red	Indicates that the channel failure risk is greater that 50%. The channel failure is at great risk if the risk percentage is between 50 and 70.

Channel Power Offset—Set or edit the upstream and downstream power offset of the channel. Options are:

– Upstream (dBm)—Sets the value of offset in dBm, negative or positive, that the COM_TX of the card uses on its PerChannelPower default value. Upstream applies to the card in the outgoing path of the circuit.

– Downstream (dBm)—Sets the value of offset in dBm, negative or positive, that the COM_TX of the card uses on its PerChannelPower default value. Downstream applies to the card in the outgoing path of the circuit.

Step 14 In the Wavelength pane, enter the following:

Working—Working check box is selected when circuit is not protected, when circuit is protected the wavelength settings can be configured for working and protected paths. Wavelength band can be selected from the drop down list.

Specific wavelength and wavelength can be selected from the drop down list.

Protected—specified the slot, port, STS (if applicable), and VT (if applicable) of the protect path.

The units are determined as follows:

wavelength (nm)
frequency (GHz)

Step 15 Expand the Path Constraints pane and enter the following:

ME/Link—contains NEs and links included in the current wizard selection context. Network Elements and links names can be typed by the user or are automatically retrieved by the system by pressing the CTRL+SPACE key combination. NE displayed (CTRL+SPACE). Network Element and links can be added to include list in path constraints pressing the + key and can be added to exclude list by pressing - key.

You can select OMS links from the ME/Link field.

Include—Include and exclude list can be modified (- key on the left side). Click Include to include the selected node in the route. The node appears in the Included Nodes list. You can modify the order of the include constraints by selecting from the list using the drag and drop functionality.
Exclude—Click Exclude to exclude the selected node from the route. The node appears in the Excluded Nodes list.

When the circuit is protected the constraints can be applied to both working and protected circuit paths.

Interaction with the network map (when circuit wizard is started from the map):

Link can be included or excluded to the working and protected path with the following actions:

– mouse right click

– the key combination highlighted in the menu

The following constraints are highlighted in the following colors:

– Links and network elements added to exclude path are highlighted in red color

– the working constraints are highlighted in green color.

Click Preroute to preroute a circuit. Click Create to create a new dwdm circuit. Click Clear to clear the entered details.

Note Preroute option is available only when all the attributes of a circuit are set to 10.6 node and can be opened only from the network map. Preroute functionality is not applicable for protected circuits.

Prerouting a DWDM Circuit

After a DWDM circuit is prerouted, the WSON circuit preview is highlighted in the network map. Available options in the DWDM window after preroute:

Activate
Reroute
Clear

Once the WSON preroute is available, you can include a link from the ME/Link drop-down to enable the Activate button.

Click Activate to activate a circuit.

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 strikethrough 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.

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 0.5 to 12.0 minutes. The Cisco default is 5 minutes.

Show Destinations button	Click this button to launch a table that shows all of the open-ended VCAT primary and secondary destinations by VCAT member number.
Routing Preferences
Route Automatically	Enable or disable automatic route selection. If enabled, Prime Optical automatically determines the route for the circuit. Alternatively, 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. Graphical Enhanced—Provides an enhanced map view that includes top-level and detailed views. Top-level view types are subnetworks or groups to which the nodes belong. Each subnetwork or group view type contains a detailed view that displays the nodes and links that belong to the specific subnetwork or group. From the detailed view, you can select the nodes and links that you need for creating the circuit. 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, Prime Optical automatically routes the circuit through the required nodes and/or links. There are several ways you can specify the required nodes and links. Choose one of the following: Graphical Graphical Enhanced Textual
Review Route Before Creation	(Available only if Route Automatically is checked) Check this check box to review the route before it is created. You can review the route in one of the following ways: Graphical Graphical Enhanced
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 Prime Optical will use to automatically determine the route for the circuit. Circuit creation fails if the same STS/VC4 is not available end-to-end. If circuit creation fails, you can try again using different values. The valid range is from 1 to 192 for SONET, or from 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, DRI, or Unprotected). Node Diverse—Specify the node diversity for each member circuit: – Required—Ensures that the primary and alternate paths are node-diverse. – Desired—Prime Optical attempts node diversity. If node diversity is impossible, Prime Optical uses primary and alternate paths that are link-diverse. – Don’t Care: Link Diverse Only—Prime Optical creates primary and alternate paths that are link-diverse. The paths might be node-diverse, but Prime Optical 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, Prime Optical 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. Alternatively, if the circuit must pass across unprotected links, Prime Optical 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—Prime Optical attempts node diversity. If node diversity is impossible, Prime Optical uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. Don’t Care: Link Diverse Only—Prime Optical 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 Prime Optical 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 are routed through working and protected links that do not share risk groups.
Overlay Ring	Check this check box if your configuration uses multiple cross-connections per node, and you want to provision the circuit across multiple rings. An overlay ring circuit traverses at least one node more than once and results in multiple cross-connections per node, per circuit. An overlay ring circuit can be protected or unprotected. Note that Prime Optical does not support a configuration where the source or destination node requires multiple cross-connections.

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. Note For VCAT circuits, the VC LO Tunnel on Transit Nodes check box is disabled if you selected Split Routing as the routing preference and you specified any route constraints in the Route Constraints pane.
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 Prime Optical cannot create a low-order tunnel or VAP/LAP.
VLAN Selection (available only for Ethernet cards or EtherGroups)
VLANs	Choose from the list of available VLANs to associate an existing VLAN to the circuit. If the Circuit VLANs list is empty, Prime Optical 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.

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

Step 1 Select a node for which to create a circuit, and open the Create Circuit wizard. For an explanation of wizard launch points, see Table 7-3.

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 a number higher than 1, you can use autoranging to create the additional circuits automatically. You can create only one circuit for the following circuit types:

ML-series
VT-v
STS-v
VT aggregation
VT tunnel

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. If you leave the field blank, Prime Optical assigns a default name to the circuit.
Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. International character sets are also supported.
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.)
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 Prime Optical 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:

– Customer ID—Identify the end user of the circuit.

– Service ID—Enter the service ID of the circuit.

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

NE ID—Choose 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—Choose 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), do the following; then, click Next :

a. Choose from the list of available VLANs to associate an existing VLAN to the circuit. If the Circuit VLANs list is empty, Prime Optical 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, do the following; then, click Next .

a. Route Automatically—Enable or disable automatic route selection. If enabled, Prime Optical 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
Graphical Enhanced
Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let Prime Optical 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
Graphical Enhanced
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. You can review the route using one of the following views:

Graphical
Graphical Enhanced

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 Prime Optical uses to automatically determine the route for the circuit. Circuit creation fails if the same STS/VC4 is not available end-to-end. If circuit creation fails, you can try again using different values. The valid range is from 1 to 192 for SONET, or from 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, Prime Optical ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking Dual Ring Interconnect . Alternatively, if the circuit must pass across unprotected links, Prime Optical creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications:

Required—Prime Optical ensures that the primary and alternate paths within the UPSR portions of the complete circuit path are node-diverse.
Desired—Prime Optical attempts node diversity. If node diversity is impossible, Prime Optical uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path.
Don’t Care: Link Diverse Only—Prime Optical 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 Prime Optical 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.

h. Overlay Ring—( For STS high-order circuits only ) Check this check box if your configuration uses multiple cross-connections per node, and you want to provision the circuit across multiple rings. An overlay ring circuit traverses at least one node more than once and results in multiple cross-connections per node, per circuit. An overlay ring circuit can be protected or unprotected. Note that Prime Optical does not support a configuration where the source or destination node requires multiple cross-connections.

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 :

Creating a Regular or Open-Ended VCAT Circuit

This section describes how to create regular and open-ended VCAT circuits (STS-v, VT-v, VC_HO_PATH_VCAT_CIRCUIT, or VC_LO_PATH_VCAT_CIRCUIT).

Prime Optical supports open-ended VCAT circuits that originate on Ethernet or ML-series cards. The destination can be OC-n or STM-n cards. You can route open-ended VCAT circuits to or from any of the cards or ports where VCAT circuits originate or terminate. Compared to a standard VCAT circuit, an open-ended VCAT circuit has only one VCG.

VCAT and open-ended VCAT circuits are supported on the following cards:

CE-100T-8—Supported on ONS 15454 SONET NEs
CE-MR-6—Supported on ONS 15310 MA SONET and ONS 15310 MA SDH NEs
CE-MR-10—Supported on ONS 15454 SONET and ONS 15454 SDH NEs
E100-WAN-8, GigE-WAN-2, STM-1-1-8-LC—Regular VCAT circuits are supported on ONS 15305 CTC NEs

Note Open-ended VCAT circuits are not supported on ONS 15305 CTC NEs.

FCMR—Supported on ONS 15454 SONET and ONS 15454 SDH NEs
ML1000, ML100T, ML-MR-10—Supported on ONS 15454 SONET and ONS 15454 SDH NEs
ML-100T-8—Supported on ONS 15310 CL, ONS 15310 MA SONET, and ONS 15310 MA SDH NEs

Note Each card supports a different number of members. You can create only bidirectional, revertive/nonrevertive, high-order/low-order path circuits. Prime Optical can route the circuits automatically, or you can route them manually. Also, all members can be routed through a single fiber, or you can specify a split-fiber routing preference. You must choose a destination for each member.

Complete the following steps to create a VCAT or open-ended VCAT circuit:

Step 1 Select a node for which to create a circuit, and open the Create Circuit wizard. For an explanation of wizard launch points, see Table 7-3.

Step 2 In the Type pane, select STS-v, VT-v, VC_HO_PATH_VCAT_CIRCUIT, or VC_LO_PATH_VCAT_CIRCUIT.

For SDH nodes:

LO_VCAT circuits from an ONS 15454 SDH CE-100T-8 card to a 15305 E-100 card, and a CE-MR-10 card to another CE-MR-10, ML-series, G1000, or OCn card are supported for VCAT circuits
LO_VCAT (VC3) circuits between a GigE-WAN-2 and ML1000 card (number of members = 2), and between a GigE-WAN-2 card and CE-100T-8 card (number of members = 1) are supported for VCAT circuits

Step 3 In the Number of Circuits field, enter the number of circuits you want to create. The Cisco default is 1. If you enter a number higher than 1, you can use autoranging to create the additional circuits automatically.

Note You can create only one VCAT circuit at a time.

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

Name—Enter a unique name for the new circuit. For VCAT circuits, the circuit name is a free-format string, up to 44 ASCII characters. If you leave the field blank, Prime Optical assigns a default name to the circuit.
Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. International character sets are also supported.
Description—Enter a circuit description of up to 256 characters.
Type—Displays the circuit type.
Bidirectional—In this release, only bidirectional VCAT circuits are supported.
State—Specify IS, OOS_DSBLD, OOS_MT, IS_AINS, or OOS_OOG (Out of Service–Out of Group).
Apply to source/destination ports—Check this check box to apply the selected state to the source and destination ports.
Symmetric— Display only.
Open VCAT—Check this check box to create an open-ended VCAT circuit. You cannot use open-ended VCAT circuits to create L2 topologies.
Member Size—Select the size of the member for the VCAT circuit. This is the unit for VCAT circuit size.
Number of Members—Select the number of members (for the member size previously selected). Different cards support different numbers of members with different sizes.
Mode—Select the LCAS mode (None, Sw-LCAS, or LCAS) for the VCAT circuit. If you select a mode other than None, only the cards supporting the LCAS mode selected are listed for the source and destination selection.
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.
Path Selectors—If the circuit will be routed on an SNCP node, 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.

– Member—Available only if the source slot is a CE-MR-10 card in Manual mode. Click Edit Members to add or remove member CTP(s) of the source TP. In the Member Selection dialog box, you can use the Add button to move the CTP(s) to the Selected CTPs list, use the Remove button to move the CTP(s) to the Available CTPs list, or click Up or Down to reorder the Selected CTPs list. Click OK to close the Member Selection dialog box.

Step 6 In the Destination pane (available for regular VCAT circuits), set the circuit destination. The options displayed depend on the circuit type, the circuit properties selected in the Attributes pane, and the cards installed on the node. Enter the following information; then, click Next :

NE ID—Choose from the list of available TPs to specify the destination TP.
Source—Specify the following:

– Destination slot.

– Port.

Step 7 In the Members Destination pane (available for open-ended VCAT circuits), do the following; then, click Next :

a. Specify the destinations:

To specify only the first member destination, check the Autoranged check box; Prime Optical will automatically choose the remaining destinations. (Note that you will lose previous selections if you switch to Autoranged.) When Autoranged is enabled, available consecutive endpoints are returned, starting from the endpoint that you selected. The destination endpoints can be on different ports only if the source endpoint supports split routing.
To specify all of the destinations, leave the Autoranged check box unchecked.

b. In the VCAT Member Number list box, select the member number to create.

c. If you want to create a secondary destination, check the Use Secondary Destination check box. Then, specify the NE ID, subnetwork ID, slot, port, STS, VC, and VT for the primary and secondary destinations.

Note The Use Secondary Destination check box is dimmed if the source endpoint does not support split routing.

d. Click the Add Destination button to save the selected endpoint for the member number shown in the VCAT Member Number list box.

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

– Fully Protected—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.

– Unprotected—To create an unprotected circuit, choose Unprotected .

– PCA—To route the circuit on a PCA route, choose PCA. PCA circuits are unprotected. Once you enable PCA, a label reading PCA will appear on the link.

– DRI—To configure dual ring interconnect protection on a VCAT circuit, choose DRI . All VCAT members must share the same DRI protection type. You cannot assign DRI protection when textual manual provisioning is enabled.

Node Diversity—Select node diversity for each member circuit.
Diverse SRLG—Select True if fully protected circuits will be routed through working or protected links that do not share risk groups.

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; however, 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)—Prime Optical does not support Dual Ring Interconnect.

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 the Fully Protected Path check box 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; however, 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.
Diverse Shared Risk Link Group—If checked, fully protected circuits are routed through working and protected links that do not share risk groups.

g. Overlay Ring—Check this check box if your configuration uses multiple cross-connections per node, and you want to provision the circuit across multiple rings. An overlay ring circuit traverses at least one node more than once and results in multiple cross-connections per node, per circuit. An overlay ring circuit can be protected or unprotected. Note that Prime Optical does not support a configuration where the source or destination node requires multiple cross-connections.
