Common Control Cards



Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.


This chapter describes Cisco ONS 15454 common control card functions. For installation and turn-up procedures, refer to the Cisco ONS 15454 Procedure Guide.

2.2  TCC+ Card

The timing communications and control card (TCC+) performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SONET data communication channel/generic communication channel (DCC/GCC) termination, and system fault detection for the ONS 15454. The TCC+ also ensures that the system maintains Telcordia timing requirements. Figure 2-1 shows the TCC+ faceplate and a block diagram of the card.

Figure 2-1 TCC+ Faceplate and Block Diagram

The node database, IP address, and system software are stored in TCC+ nonvolatile memory, which allows quick recovery in the event of a power or card failure.

The TCC+ supports multichannel, high-level data link control (HDLC) processing for the DCC/GCC. Up to 48 DCCs/GCCs can be routed over the Serial Communication Interface (SCI) and terminated at the TCC+. The TCC+ selects and processes ten DCCs/GCCs to facilitate remote system management interfaces.

The TCC+ performs all system-timing functions for each ONS 15454. The TCC+ monitors the recovered clocks from each traffic card and two DS-1 (BITS) interfaces for frequency accuracy. The TCC+ selects a recovered clock, a building integrated timing source (BITS), or an internal Stratum 3 reference as the system-timing reference. You can provision any of the clock inputs as primary or secondary timing sources. A slow-reference tracking loop allows the TCC+ to synchronize with the recovered clock, which provides holdover if the reference is lost.

Install TCC+ cards in Slots 7 and 11 for redundancy. If the active TCC+ fails, traffic switches to the protect TCC+. All TCC+ protection switches conform to protection switching standards of less than 50 ms.

The TCC+ features an RJ-45 10BASE-T LAN port and an EIA/TIA-232 DB9 type craft interface for user interfaces. The TL1 craft port runs at 9600 bps.


Caution Do not operate the ONS 15454 with only one TCC+ card. Two TCC+ cards must always be installed.

2.2.1  TCC+ Card-Level Indicators

Table 2-10 describes the two card-level LEDs on the TCC+ faceplate.

Table 2-10 TCC+ Card-Level Indicators  

Card-Level LEDs
Definition
Red FAIL LED

Indicates a TCC+ hardware problem. Replace the unit if the FAIL LED persists.

ACT/STBY LED
Green (Active)
Amber (Standby)

The ACT/STBY (Active/Standby) LED indicates that the TCC+ is active (green) or in standby (amber). The ACT/STBY LED also provides the timing reference and shelf control. When the active TCC+ is writing to its database or to the standby TCC+ database, the card LEDs blink.

To avoid memory corruption, only remove the TCC+ when it is in standby and when the LED is not blinking.


2.2.2  Network-Level Indicators

Table 2-11 describes the six network-level LEDs on the TCC+ faceplate.

Table 2-11 TCC+ Network-Level Indicators  

System-Level LEDs
Definition
Red CRIT LED

Indicates a critical alarm in the network at the local node.

Red MAJ LED

Indicates a major alarm in the network at the local node.

Amber MIN LED

Indicates a minor alarm in the network at the local node.

Red REM LED

Provides first-level alarm isolation. The REM LED turns red when an alarm is present in one or more of the remote nodes.

Green SYNC LED

Indicates that node timing is synchronized to an external reference.

Green ACO LED

After pressing the alarm cutoff (ACO) button, the ACO LED turns green. The ACO button opens the audible alarm closure on the backplane. The ACO state is stopped if a new alarm occurs. After the originating alarm is cleared, the ACO LED and audible alarm control are reset.


2.2.3  TCC+ Card Specifications

The TCC+ has the following specifications:

CTC software

Compliance

ONS 15454 cards, when installed in a system, comply with these standards:
Safety: UL 1950, CSA C22.2 No. 950, EN 60950, IEC 60950

2.3  TCC2 Card

The Advanced Timing Communications and Control (TCC2) card performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SONET section overhead (SOH) DCC/GCC termination, and system fault detection for the ONS 15454. The TCC2 also ensures that the system maintains Stratum 3 (Telcordia GR-253-CORE) timing requirements. It monitors the supply voltage of the system.


Note The TCC2 card requires Software Release 4.0.0 or later.



Note The LAN interface of the TCC2 card meets the standard Ethernet specifications by supporting a cable length of 328 ft. (100 m) at temperatures from 32 to 149 degrees Fahrenheit (0 to 65 degrees Celsius). The interfaces can operate with a cable length of 32.8 ft. (10 m) maximum at temperatures from -40 to 32 degrees Fahrenheit (-40 to 0 degrees Celsius).


Figure 2-2 shows the TCC2 faceplate.

Figure 2-2 TCC2 Faceplate

Figure 2-3 shows a block diagram of the card.

Figure 2-3 TCC2 Block Diagram

The TCC2 supports multichannel, HDLC processing for the DCC/GCC. In Hardware R3.2 or later with Software R4.0 or later, up to 32 DCCs/GCCs can be routed over the TCC2 and up to 32 DCCs/GCCs can be terminated at the TCC2 (subject to the available optical digital communication channels). The TCC2 selects and processes 32 DCCs/GCCs to facilitate remote system management interfaces. The TCC2 hardware is prepared for 84 DCCs/GCCs, which will be available in a future software release.

The TCC2 also originates and terminates a cell bus carried over the module. The cell bus supports links between any two cards in the node, which is essential for peer-to-peer communication. Peer-to-peer communication accelerates protection switching for redundant cards.

The node database, IP address, and system software are stored in TCC2 nonvolatile memory, which allows quick recovery in the event of a power or card failure.

The TCC2 performs all system-timing functions for each ONS 15454. The TCC2 monitors the recovered clocks from each traffic card and two BITS ports for frequency accuracy. The TCC2 selects a recovered clock, a BITS, or an internal Stratum 3 reference as the system-timing reference. You can provision any of the clock inputs as primary or secondary timing sources. A slow-reference tracking loop allows the TCC2 to synchronize with the recovered clock, which provides holdover if the reference is lost.

The TCC2 monitors both supply voltage inputs of the shelf. An alarm is generated if one of the supply voltage inputs has a voltage out of the specified range.

Install TCC2 cards in Slots 7 and 11 for redundancy. If the active TCC2 fails, traffic switches to the protect TCC2. All TCC2 protection switches conform to protection switching standards when the bit error rate (BER) counts are not in excess of 1 * 10 exp - 3 and completion time is less than 50 ms.

The TCC2 card has two built-in interface ports for accessing the system: an RJ-45 10BASE-T LAN interface and an EIA/TIA-232 ASCII interface for local craft access. It also has a 10BASE-T LAN port for user interfaces via the backplane.


Note Cisco does not support operation of the ONS 15454 with only one TCC2 card. For full functionality and to safeguard your system, always operate in a redundant configuration.



Note When a second TCC2 card is inserted into a node, it synchronizes its software, its backup software, and its database with the active TCC2. If the software version of the new TCC2 does not match the version on the active TCC2, the newly inserted TCC2 copies from the active TCC2, taking about 15 to 20 minutes to complete. If the backup software version on the new TCC2 does not match the version on the active TCC2, the newly inserted TCC2 copies the backup software from the active TCC2 again, taking about 15 to 20 minutes. Copying the database from the active TCC2 takes about 3 minutes. Depending on the software version and backup version the new TCC2 started with, the entire process can take between 3 and 40 minutes.


2.3.1  TCC2 Card-Level Indicators

The TCC2 faceplate has eight LEDs. The first two LEDs are card-level indicators. These indicators are described in Table 2-12.

Table 2-12 TCC2 Card-Level Indicators  

Card-Level LEDs
Definition

Red FAIL LED

This LED is on during reset. The FAIL LED flashes during the boot and write process. Replace the card if the FAIL LED persists.

ACT/STBY LED

Green (Active)

Yellow (Standby)

The ACT/STBY (Active/Standby) LED indicates the TCC2 is active (green) or in standby (yellow) mode. The ACT/STBY LED also provides the timing reference and shelf control. When the active TCC2 is writing to its database or to the standby TCC2 database, the card LEDs blink. To avoid memory corruption, do not remove the TCC2 when the active or standby LED is blinking.

2.4  XC Card

The cross-connect (XC) card is the central element for ONS 15454 switching. Available cross-connects are the XC, XCVT, and XC10G cards. The XC establishes connections and performs time division switching (TDS) at the STS-1 level between ONS 15454 traffic cards. Figure 2-4 shows the XC card faceplate and block diagram.

Figure 2-4 XC Card Faceplate and Block Diagram

The switch matrix on the XC card consists of 288 bidirectional ports.When creating bidirectional STS-1 cross-connects, each cross-connect uses two STS-1 ports. This results in 144 bidirectional STS-1 cross-connects. The switch matrix is fully crosspoint, nonblocking, and broadcast supporting. (Any STS-1 on any port can be connected to any other port, meaning that the STS cross-connections are nonblocking.) This allows network operators to concentrate or groom low-speed traffic from line cards onto high-speed transport spans and to drop low-speed traffic from transport spans onto line cards.

Figure 2-5 XC Cross-Connect Matrix

The XC card has 12 input ports and 12 output ports. Four input and output ports operate at either STS-12 or STS-48 rates. The remaining eight input and output ports operate at the STS-12 rate. An STS-1 on any of the input ports can be mapped to an STS-1 output port, thus providing full STS-1 time slot assignments (TSA).

The XC card works with the TCC+/TCC2 card to maintain connections and set up cross-connects within the ONS 15454. The XC, XCVT, or XC10G is required to operate the ONS 15454. You establish cross-connect and provisioning information through CTC. The TCC+/TCC2 establishes the proper internal cross-connect information and relays the setup information to the cross-connect card.


Caution Do not operate the ONS 15454 with only one XC, XCVT, or XC10G card. Two cross-connect cards of the same type (either two XC, two XCVT, or two XC10G cards) must always be installed.

The card has no external interfaces. All cross-connect card interfaces are provided through the ONS 15454 backplane.

2.5  XCVT Card

The XCVT card provides the same STS capability as a standard XC card and also provides VT cross-connection. The XCVT provides nonblocking STS-48 capacity to Slots 5, 6, 12, and 13, and nonbidirectional blocking STS-12 capacity to Slots 1 to 5 and 14 to 17. Any STS-1 on any port can be connected to any other port, meaning that the STS cross-connections are nonblocking.

Figure 2-6 shows the XCVT faceplate and block diagram.

Figure 2-6 XCVT Faceplate and Block Diagram

The STS-1 switch matrix on the XCVT card consists of 288 bidirectional ports and adds a VT matrix that can manage up to 336 bidirectional VT1.5 ports or the equivalent of a bidirectional STS-12. The VT1.5-level signals can be cross connected, dropped, or rearranged. The TCC+/TCC2 assigns bandwidth to each slot on a per STS-1 or per VT1.5 basis. The switch matrices are fully crosspoint and broadcast supporting.

The XC-VT provides:

288 STS Bi-directional Ports

144 STS Bi-directional Cross-connects

672 VT1.5 Ports Via 24 Logical STS Ports

336 VT1.5 Bi-directional Cross-connects

Non-blocking @ STS Level

STS-1/3c/6c/12c/48c Cross-connects

The XCVT card works with the TCC+/TCC2 card to maintain connections and set up cross-connects within the node. The XCVT, XC10G, or XC is required to operate the ONS 15454. You can establish cross-connect (circuit) information through CTC. The TCC+/TCC2 establishes the proper internal cross-connect information and relays the setup information to the XCVT card.


Caution Do not operate the ONS 15454 with only one XC, XCVT, or XC10G card. Two cross-connect cards of the same type (either two XC, two XCVT, or two XC10G cards) must always be installed.

Figure 2-7 shows the cross-connect matrix.

2.5.2  XCVT Hosting DS3XM-6

The XCVT card works with DS3XM-6 (transmux) cards. A single DS3XM-6 can demultiplex (map down to a lower rate) six DS-3 signals into 168 VT1.5s that the XCVT card manages and cross connects. XCVT cards host a maximum of 336 bidirectional VT1.5s. In most network configurations, two DS3XM-6 cards are paired as working and protect cards.

2.5.3  XCVT Card-Level Indicators

Table 2-16 shows the two card-level LEDs on the XCVT faceplate.

The red FAIL LED indicates that the card's processor is not ready. Replace the card if the red FAIL LED persists.

ACT/STBY LED
Green (Active)
Amber (Standby)

The ACT/STBY (Active/Standby) LED indicates whether the XCVT is active and carrying traffic (green), or in standby mode to the active XCVT card (amber).


2.5.4  XC/XCVT Compatibility

The XCVT card is compatible with the XC cards. The XCVT supports run-time compatibility with the XC cross-connect both within a single node and within a ring of mixed XCVT and XC nodes. However, working and protect cards within a single ONS 15454 must be either two XC cards or two XCVT cards.

The XC and XCVT are supported in36 path protectionand bidirectional line switched ring (BLSR) configurations. VT and STS-level cross-connect and protection management are also supported in either type of ring. Nodes that rearrange or drop VTs must use an XCVT. Nodes that only rearrange or drop STSs can use an XC. You do not need to upgrade STS-only nodes to XCVT in a ring that can handle both VT and STS drop/rearrangement. In this scenario, however, the XC must run Software R2.0 or later.

When upgrading from XC to XCVT cards, the first XCVT card installed acts as an XC card until the second XCVT card is installed.

To create an STS-capable ring that allows VT drops at some nodes, all of the nodes in the ring must first run Software R2.0 or later. The nodes that allow VT drops must use XCVT, but the nodes that do not allow VT drops can use the XC or XCVT card.

2.5.5  XCVT Card Specifications

The XCVT card has the following specifications:

Environmental

Operating temperature:

C-Temp (15454-XC-VT): 32 to 131 degrees Fahrenheit (0 to +55 degrees Celsius)

2.6  XC10G Card

The cross-connect 10 Gbps (XC10G) card cross connects STS-12, STS-48, and STS-192 signal rates. The XC10G allows up to four times the bandwidth of the XC and XCVT cards. The XC10G provides a maximum of 576 STS-1 cross-connections through 1152 STS-1 ports. Any STS-1 on any port can be connected to any other port, meaning that the STS cross-connections are nonblocking.

Figure 2-8 shows the XC10G faceplate and block diagram.

Figure 2-8 XC10G Faceplate and Block Diagram

The XC10G card manages up to 672 bidirectional VT1.5 ports and 1152 bidirectional STS-1 ports. The TCC+/TCC2 assigns bandwidth to each slot on a per STS-1 or per VT1.5 basis.

The XC10G, XCVT, or XC is required to operate the ONS 15454. You can establish cross-connect (circuit) information through the Cisco Transport Controller (CTC). The TCC+/TCC2 establishes the proper internal cross-connect information and sends the setup information to the cross-connect card.

The XC10G card provides:

1152 STS Bidirectional ports

576 STS Bidirectional cross-connects

672 VT1.5 Ports Via 24 logical STS ports

336 VT1.5 Bidirectional cross-connects

Non-blocking @ STS level

The ACT/STBY (Active/Standby) LED indicates whether the XC10G is active and carrying traffic (green), or in standby mode to the active XC10G card (amber).


2.6.4  XC/XCVT/XC10G Compatibility

The XC10G supports the same features as the XC and XCVT cards. The XC10G card is required for OC-192 operation and OC-48 any-slot operation. Do not use the XCVT or XC cards if you are using the OC-192 card, or if you placed one of the OC-48 any-slot cards in any of the Slots 1 to 4 or 14 to 17.


Note A configuration mismatch alarm occurs when a XC or XCVT cross-connect card co-exists with an OC-192 card placed in Slots 5, 6, 12, or 13, or with an OC-48 card placed in Slots 1 to 4 or 14 to 17.


The TCC+/TCC2 card, Software R3.1, or later and the new 15454-SA-ANSI shelf assembly are required for the operation of the XC10G. If you are using Ethernet cards, the E1000-2-G or the E100T-G must be used when the XC10G cross-connect card is in use. Do not pair an XC or XCVT with an XC10G. When upgrading from XC or XCVT to the XC10G card, refer to the Cisco ONS 15454 Procedure Guide for more information.

The upgrade procedure from the XC/XCVT cards to the XC10G card only applies to XC/XCVT cards that are installed in the 15454-SA-ANSI (Software R3.1 and later). You cannot perform this upgrade from shelves released prior to Software R3.1. The XC10G requires the 15454-SA-ANSI.

2.7  AIC Card

The optional Alarm Interface Controller (AIC) card provides customer-defined alarm input/output (I/O) and supports local and express orderwire. Figure 2-10 shows the AIC faceplate and a block diagram of the card.

Figure 2-10 AIC Faceplate and Block Diagram

2.7.1  External Alarms and Controls

The AIC card provides input/output alarm contact closures. You can define up to four external alarms and four external controls. The physical connections are made using the backplane wire-wrap pins. The alarms are defined using CTC and TL1. For instructions, refer to the Cisco ONS 15454 Procedure Guide.

Each alarm contact has a corresponding LED on the front panel of the AIC that indicates the status of the alarm. External alarms (input contacts) are typically used for external sensors such as open doors, temperature sensors, flood sensors, and other environmental conditions. External controls (output contacts) are typically used to drive visual or audible devices such as bells and lights, but they can control other devices such as generators, heaters, and fans.

You can program each of the four input alarm contacts separately. Choices include Alarm on Closure or Alarm on Open, an alarm severity of any level (Critical, Major, Minor, Not Alarmed, Not Reported), a Service Affecting or Non-Service Affecting alarm-service level, and a 63-character alarm description for CTC display in the alarm log. You cannot assign the fan-tray abbreviation for the alarm; the abbreviation reflects the generic name of the input contacts. The alarm condition remains raised until the external input stops driving the contact or you provision the alarm input.

The output contacts can be provisioned to close on a trigger or to close manually. The trigger can be a local alarm severity threshold, a remote alarm severity, or a virtual wire:

Local NE alarm severity: A hierarchy of non-reported, non-alarmed, minor, major or critical alarm severities that you set to cause output closure. For example, if the trigger is set to minor, a minor alarm or above is the trigger.

Remote NE alarm severity: Same as the Local NE alarm severity but applies to remote alarms only.

Virtual wire entities: You can provision any environmental alarm input to raise a signal on any virtual wire on external outputs 1 through 4 when the alarm input is an event. You can provision a signal on any virtual wire as a trigger for an external control output.

You can also program the output alarm contacts (external controls) separately. In addition to provisionable triggers, you can manually force each external output contact to open or close. Manual operation takes precedence over any provisioned triggers that might be present.

2.7.2  Orderwire

Orderwire allows a craftsperson to plug a phoneset into an ONS 15454 and communicate with craftspeople working at other ONS 15454s or other facility equipment. The orderwire is a pulse code modulation (PCM) encoded voice channel that uses E1 or E2 bytes in section/line overhead.

The AIC allows simultaneous use of both local (section overhead signal) and express (line overhead channel) orderwire channels on a SONET ring or particular optics facility. Local orderwire also allows communication at regeneration sites when the regenerator is not a Cisco device.

You can provision orderwire functions with CTC similar to the current provisioning model for DCC/GCC channels. In CTC you provision the orderwire communications network during ring turn-up so that all NEs on the ring can reach one another. Orderwire terminations (that is, the optics facilities that receive and process the orderwire channels) are provisionable. Both express and local orderwire can be configured as on or off on a particular SONET facility. The ONS 15454 supports up to four orderwire channel terminations per shelf. This allows linear, single ring, dual ring, and small hub-and-spoke configurations. Keep in mind that orderwire is not protected in ring topologies such as BLSR and path protection.


Caution Do not configure orderwire loops. Orderwire loops cause feedback that disables the orderwire channel.

The ONS 15454 implementation of both local and express orderwire is broadcast in nature. The line acts as a party line. There is no signaling for private point-to-point connections. Anyone who picks up the orderwire channel can communicate with all other participants on the connected orderwire subnetwork. The local orderwire party line is separate from the express orderwire party line. Up to four OC-N facilities for each local and express orderwire are provisionable as orderwire paths.

The AIC supports a "call" button on the module front panel which, when pressed, causes all ONS 15454 AICs on the orderwire subnetwork to "ring." The ringer/buzzer resides on the AIC. There is also a "ring" LED that mimics the AIC ringer. It flashes when any "call" button is pressed on the orderwire subnetwork. The "call" button and ringer LED allow a remote craftsperson to get the attention of craftspeople across the network.

Table 2-19 shows the pins on the orderwire ports that correspond to the tip and ring orderwire assignments.

The optional Alarm Interface Controller-International (AIC-I) card provides customer-defined (environmental) alarms and controls and supports local and express orderwire. It provides 12 customer-defined input and 4 customer-defined input/output contacts. The physical connections are via the backplane wire-wrap pin terminals. If you use the additional alarm expansion panel (AEP), the AIC-I card can support up to 32 inputs and 16 outputs, which are connected on the AEP connectors. A power monitoring function monitors the supply voltage (-48 VDC). Figure 2-12 shows the AIC-I faceplate and a block diagram of the card.


Note After you have upgraded a shelf to the AIC-I card and have set new attributes, you cannot downgrade the shelf back to the AIC card.

Yellow OUTPUT LED

The OUTPUT LED is yellow when there is an alarm condition on at least one of the alarm outputs.

Green RING LED

The RING LED on the local orderwire (LOW) side is flashing green when a call is received on the LOW.

Green RING LED

The RING LED on the express orderwire (EOW) side is flashing green when a call is received on the EOW.


2.8.2  External Alarms and Controls

The AIC-I card provides input/output alarm contact closures. You can define up to 12 external alarm inputs and 4 external alarm inputs/outputs (user configurable). The physical connections are made using the backplane wire-wrap pins. See the "Alarm Expansion Panel" section on page 29 for information about increasing the number of input/output contacts.

LEDs on the front panel of the AIC-I indicate the status of the alarm lines, one LED representing all of he inputs and one LED representing all of the outputs. External alarms (input contacts) are typically used for external sensors such as open doors, temperature sensors, flood sensors, and other environmental conditions. External controls (output contacts) are typically used to drive visual or audible devices such as bells and lights, but they can control other devices such as generators, heaters, and fans.

You can program each of the twelve input alarm contacts separately. Choices include Alarm on Closure or Alarm on Open, an alarm severity of any level (Critical, Major, Minor, Not Alarmed, Not Reported), a Service Affecting or Non-Service Affecting alarm-service level, and a 63-character alarm description for CTC display in the alarm log. You cannot assign the fan-tray abbreviation for the alarm; the abbreviation reflects the generic name of the input contacts. The alarm condition remains raised until the external input stops driving the contact or you provision the alarm input.

The output contacts can be provisioned to close on a trigger or to close manually. The trigger can be a local alarm severity threshold, a remote alarm severity, or a virtual wire:

Local NE alarm severity: A hierarchy of non-reported, non-alarmed, minor, major or critical alarm severities that you set to cause output closure. For example, if the trigger is set to minor, a minor alarm or above is the trigger.

Remote NE alarm severity: Same as the Local NE alarm severity but applies to remote alarms only.

Virtual wire entities: You can provision any environmental alarm input to raise a signal on any virtual wire on external outputs 1 through 4 when the alarm input is an event. You can provision a signal on any virtual wire as a trigger for an external control output.

You can also program the output alarm contacts (external controls) separately. In addition to provisionable triggers, you can manually force each external output contact to open or close. Manual operation takes precedence over any provisioned triggers that might be present.


Note The number of inputs and outputs can be increased using the AEP. The AEP is connected to the shelf backplane and requires an external wire-wrap panel.


2.8.3  Orderwire

Orderwire allows a craftsperson to plug a phoneset into an ONS 15454 and communicate with craftspeople working at other ONS 15454s or other facility equipment. The orderwire is a pulse code modulation (PCM) encoded voice channel that uses E1 or E2 bytes in section/line overhead.

The AIC-I allows simultaneous use of both local (section overhead signal) and express (line overhead channel) orderwire channels on a SONET ring or particular optics facility. Express orderwire also allows communication via regeneration sites when the regenerator is not a Cisco device.

You can provision orderwire functions with CTC similar to the current provisioning model for DCC/GCC channels.

The local orderwire party line is separate from the express orderwire party line. Up to four OC-N facilities for each local and express orderwire are provisionable as orderwire paths.


Note The OC3 IR 4/STM1 SH 1310 card does not support the express orderwire channel.


The AIC-I supports selective dual tone multifrequency (DTMF) dialing for telephony connectivity, which causes one AIC-I card or all ONS 15454 AIC-I cards on the orderwire subnetwork to "ring." The ringer/buzzer resides on the AIC-I. There is also a "ring" LED that mimics the AIC-I ringer. It flashes when a call is received on the orderwire subnetwork. A party line call is initiated pressing *0000 on the DTMF pad. Individual dialing is initiated by pressing * and the individual four-digit number on the DTMF pad.

Ports used for orderwire are standard RJ-11 connectors, shown in Figure 2-13. The pins on the orderwire connector correspond to the tip and ring orderwire assignments, shown in Table 2-21.

When provisioning the orderwire subnetwork, make sure that an orderwire loop does not exist. Loops cause oscillation and an unusable orderwire channel.

2.8.4  Power Monitoring

The AIC-I card provides a power monitoring circuit that monitors the supply voltage of -48 VDC for presence, undervoltage, or overvoltage.

2.8.5  User Data Channel

The user data channel (UDC) features a dedicated data channel of 64 kbps (F1 byte) between two nodes in an ONS 15454 network. Each AIC-I card provides two user data channels, UDC-A and UDC-B, through separate RJ-11 connectors on the front of the AIC-I. Each UDC can be routed to an individual optical interface in the ONS 15454 system. For instructions, refer to the Cisco ONS 15454 Procedure Guide.

The UDC ports are standard RJ-11 receptacles. Table 2-22 lists the UDC pin assignments.

2.8.6  Data Communications Channel/Generic Communications Channel

The data communications channel/generic communication channel (DCC/GCC) features a dedicated data channel of 576 kbps (D4 to D12 bytes) between two nodes in an ONS 15454 network. Each AIC-I card provides two data communications channels, DCC-A and DCC-B, through separate RJ-45 connectors on the front of the AIC-I. Each DCC/GCC can be routed to an individual optical interface in the ONS 15454 system. For instructions, refer to the Cisco ONS 15454 Procedure Guide.

The DCC/GCC ports are standard RJ-45 receptacles. Table 2-23 lists the DCC/GCC pin assignments.
