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.
Chapter topics include:
2.1 Common Control Card Overview
The card overview section summarizes card functions and compatibility.
Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. The cards are then installed into slots displaying the same symbols. See the "Card Slot Requirements" section for a list of slots and symbols.
2.1.1 Cards Summary

2.2 TCC2 Card
Note For hardware specifications, see the "TCC2 Card Specifications" section.
The 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 2-1 shows the faceplate and block diagram for the TCC2 card.
Figure 2-1 TCC2 Card Faceplate and Block Diagram
2.2.1 TCC2 Card Functionality
The TCC2 card supports multichannel, high-level data link control (HDLC) processing for the DCC. Up to 84 DCCs can be routed over the TCC2 card and up to 84 section DCCs can be terminated at the TCC2 card (subject to the available optical digital communication channels). The TCC2 card selects and processes 84 DCCs to facilitate remote system management interfaces.
The TCC2 card 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 card nonvolatile memory, which allows quick recovery in the event of a power or card failure.
The TCC2 card performs all system-timing functions for each ONS 15454. The TCC2 monitors the recovered clocks from each traffic card and two BITS ports (DS1, 1.544 MHz) 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 on 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 10BaseT LAN interface and an EIA/TIA-232 ASCII interface for local craft access. It also has a 10BaseT LAN port for user interfaces over the backplane.
Note When using the LAN RJ-45 craft interface or back panel wirewrap LAN connection, the connection must be 10BASE T, half duplex. Full duplex and autonegotiate settings should not be used because they might result in a loss of visibility to the node.
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 with two TCC2 cards.
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.
2.2.2 TCC2 Card-Level Indicators
The TCC2 faceplate has ten LEDs. Table 2-8 describes the two card-level LEDs on the TCC2 card faceplate.
2.2.3 Network-Level Indicators
Table 2-9 describes the six network-level LEDs on the TCC2 faceplate.
2.2.4 Power-Level Indicators
Table 2-10 describes the two power-level LEDs on the TCC2 faceplate.
2.3 TCC2P Card
Note For hardware specifications, see the "TCC2P Card Specifications" section.
The TCC2P card is an enhanced version of the TCC2 card. For Software Release 5.0 and later, the primary enhancements are Ethernet security features and 64K composite clock BITS timing.
The TCC2P card performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SONET SOH DCC/GCC termination, and system fault detection for the ONS 15454. The TCC2P card also ensures that the system maintains Stratum 3 (Telcordia GR-253-CORE) timing requirements. It monitors the supply voltage of the system.
Note The TCC2P card requires Software Release 4.0.0 or later.
Note The LAN interface of the TCC2P 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 faceplate and block diagram for the TCC2P card.
Figure 2-2 TCC2P Faceplate and Block Diagram
2.3.1 TCC2P Functionality
The TCC2P card supports multichannel, high-level data link control (HDLC) processing for the DCC. Up to 84 DCCs can be routed over the TCC2P card and up to 84 section DCCs can be terminated at the TCC2P card (subject to the available optical digital communication channels). The TCC2P selects and processes 84 DCCs to facilitate remote system management interfaces.
The TCC2P card 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 TCC2P card nonvolatile memory, which allows quick recovery in the event of a power or card failure.
The TCC2P card performs all system-timing functions for each ONS 15454. The TCC2P card monitors the recovered clocks from each traffic card and two BITS ports for frequency accuracy. The TCC2P card selects a recovered clock, a BITS clock, 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 TCC2P card to synchronize with the recovered clock, which provides holdover if the reference is lost.
The TCC2P card supports a 64 kHz + 8 kHz composite clock BITS input (BITS IN) as well as a 6.312-MHz BITS OUT clock. The BITS clock on the system is configurable as DS1 (default), 1.544 MHz, or 64 kHz. The BITS OUT clock runs at a rate determined by the BITS IN clock, as follows:
If BITS IN = DS1, then BITS OUT = DS1 (default)
A BITS output interface configured as 6.312 MHz complies with ITU-T G.703, Appendix II, Table II.4, with a monitor level of -40 dBm +/- 4 dBm.
The TCC2P card monitors both supply voltage inputs on the shelf. An alarm is generated if one of the supply voltage inputs has a voltage out of the specified range.
Install TCC2P cards in Slots 7 and 11 for redundancy. If the active TCC2P card fails, traffic switches to the protect TCC2P card. All TCC2P card protection switches conform to protection switching standards when the BER counts are not in excess of 1 * 10 exp - 3 and completion time is less than 50 ms.
The TCC2P card has two built-in Ethernet interface ports for accessing the system: one built-in RJ-45 port on the front faceplate for on-site craft access and a second port on the backplane. The rear Ethernet interface is for permanent LAN access and all remote access via TCP/IP as well as for Operations Support System (OSS) access. The front and rear Ethernet interfaces can be provisioned with different IP addresses using CTC.
Two EIA/TIA-232 serial ports, one on the faceplate and a second on the backplane, allow for craft interface in TL1 mode.
Note To use the serial port craft interface wire-wrap pins on the backplane, the DTR signal line on the backplane port wire-wrap pin must be connected and active.
Note When using the LAN RJ-45 craft interface or back panel wirewrap LAN connection, the connection must be 10BASE T, half duplex. Full duplex and autonegotiate settings should not be used because they might result in a loss of visibility to the node.
Note Cisco does not support operation of the ONS 15454 with only one TCC2P card. For full functionality and to safeguard your system, always operate with two TCC2P cards.
Note When a second TCC2P card is inserted into a node, it synchronizes its software, its backup software, and its database with the active TCC2P card. If the software version of the new TCC2P card does not match the version on the active TCC2P card, the newly inserted TCC2P card copies from the active TCC2P card, taking about 15 to 20 minutes to complete. If the backup software version on the new TCC2P card does not match the version on the active TCC2P card, the newly inserted TCC2P card copies the backup software from the active TCC2P card again, taking about 15 to 20 minutes. Copying the database from the active TCC2P card takes about 3 minutes. Depending on the software version and backup version the new TCC2P card started with, the entire process can take between 3 and 40 minutes.
2.3.2 TCC2P Card-Level Indicators
The TCC2P faceplate has ten LEDs. Table 2-11 describes the two card-level LEDs on the TCC2P faceplate.
2.3.3 Network-Level Indicators
Table 2-12 describes the six network-level LEDs on the TCC2P faceplate.
2.3.4 Power-Level Indicators
Table 2-13 describes the two power-level LEDs on the TCC2P faceplate.
2.4 XCVT Card
Note For hardware specifications, see the "XCVT Card Specifications" section.
The Cross Connect Virtual Tributary (XCVT) card establishes connections at the STS-1 and VT levels. The XCVT provides STS-48 capacity to Slots 5, 6, 12, and 13, and STS-12 capacity to Slots 1 to 4 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 2-3 shows the XCVT faceplate and block diagram.
Figure 2-3 XCVT Faceplate and Block Diagram
2.4.1 XCVT Functionality
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 TCC2/TCC2P card 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 XCVT card provides:
•288 STS bidirectional ports
•144 STS bidirectional cross-connects
•672 VT1.5 ports via 24 logical STS ports
•336 VT1.5 bidirectional cross-connects
•Nonblocking at the STS level
•STS-1/3c/6c/12c/48c cross-connects
The XCVT card works with the TCC2/TCC2P cards to maintain connections and set up cross-connects within the node. The cross-connect cards (such as the XCVT and XC10G), installed in Slots 8 and 10, are required to operate the ONS 15454. You can establish cross-connect (circuit) information through CTC. The TCC2/TCC2P cards establish the proper internal cross-connect information and relay the setup information to the XCVT card.
Do not operate the ONS 15454 with only one cross-connect card. Two cross-connect cards of the same type (two XCVT or two XC10G cards) must always be installed.
Figure 2-4 shows the cross-connect matrix.
Figure 2-4 XCVT Cross-Connect Matrix
2.4.2 VT Mapping
The VT structure is designed to transport and switch payloads below the DS-3 rate. The ONS 15454 performs VT mapping according to Telcordia GR-253-CORE standards. Table 2-14 shows the VT numbering scheme for the ONS 15454 as it relates to the Telcordia standard.
2.4.3 XCVT Hosting DS3XM-6 or DS3XM-12
A DS3XM card can demultiplex (map down to a lower rate) M13-mapped DS-3 signals into 28 DS-1s that are then mapped to VT1.5 payloads. The VT1.5s can then be cross-connected by the XCVT card. The XCVT card can host a maximum of 336 bidirectional VT1.5s.
2.4.4 XCVT Card-Level Indicators
Table 2-15 shows the two card-level LEDs on the XCVT card faceplate.
2.5 XC10G Card
Note For hardware specifications, see the "XC10G Card Specifications" section.
The 10 Gigabit Cross Connect (XC10G) card establishes connections at the STS-1 and VT levels. The XC10G provides STS-192 capacity to Slots 5, 6, 12, and 13, and STS-48 capacity to Slots 1 to 4 and 14 to 17. The XC10G allows up to four times the bandwidth of the 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 2-5 shows the XC10G faceplate and block diagram.
Figure 2-5 XC10G Faceplate and Block Diagram
2.5.1 XC10G Functionality
The XC10G card manages up to 672 bidirectional VT1.5 ports and 1152 bidirectional STS-1 ports. The TCC2/TCC2P cards assign bandwidth to each slot on a per STS-1 or per VT1.5 basis.
Two cross-connect cards, installed in Slots 8 and 10, are required to operate the ONS 15454. You can establish cross-connect (circuit) information through the CTC. The cross-connect card 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
•Nonblocking at STS level
•STS-1/3c/6c/12c/48c/192c cross-connects
Do not operate the ONS 15454 with only one XCVT or XC10G card. Two cross-connect cards of the same type (either two XCVT or two XC10G cards) must always be installed.
Figure 2-6 shows the cross-connect matrix.
Figure 2-6 XC10G Cross-Connect Matrix
2.5.2 VT Mapping
The VT structure is designed to transport and switch payloads below the DS-3 rate. The ONS 15454 performs VT mapping according to Telcordia GR-253-CORE standards. Table 2-16 shows the VT numbering scheme for the ONS 15454 as it relates to the Telcordia standard.
2.5.3 XC10G Hosting DS3XM-6 or DS3XM-12
A DS3XM card can demultiplex (map down to a lower rate) M13-mapped DS-3 signals into 28 DS-1s that are then mapped to VT1.5 payloads. The VT1.5s can then be cross-connected by the XC10G card. The XC10G card can host a maximum of 336 bidirectional VT1.5s.
2.5.4 XC10G Card-Level Indicators
Table 2-17 describes the two card-level LEDs on the XC10G faceplate.
2.5.5 XCVT/XC10G/XC-VXC-10G Compatibility
The XC10G and XC-VXC-10G cards support the same features as the XCVT card. The XC10G or XC-VXC-10G cards are required for OC-192, OC-48 any-slot (AS), OC3-8, and OC12-4 operation. Do not use the XCVT card if you are using an OC-192, OC3-8, or OC12-4 card or if you install an OC-48 AS card in Slots 1 to 4 or 14 to 17.
Note A configuration mismatch alarm occurs when an XCVT cross-connect card co-exists with an OC-192, OC3-8, or OC12-4 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.
If you are using Ethernet cards, the E1000-2-G or the E100T-G must be used when the XC10G or XC-VXC-10G cross-connect card is in use. Do not pair an XCVT card with an XC10G or XC-VXC-10G card. When upgrading from an XCVT to the XC10G or XC-VXC-10G card, refer to the "Upgrade Cards and Spans" chapter in the Cisco ONS 15454 Procedure Guide for more information.
2.6 XC-VXC-10G Card
Note For hardware specifications, see the "XC-XVC-10G Card Specifications" section.
The XC-VXC-10G card establishes connections at the STS and VT levels. The XC-VXC-10G provides STS-192 capacity to Slots 5, 6, 12, and 13, and STS-48 capacity to Slots 1 to 4 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 2-7 shows the XC-VXC-10G faceplate and block diagram.
Figure 2-7 XC-VXC-10G Faceplate and Block Diagram
2.6.1 XC-VXC-10G Functionality
The XC-VXC-10G card manages up to 1152 bidirectional high-order STS-1 ports. In addition, it is able to simultaneously manage one of the following low-order VT cross-connect arrangements:
•2688 bidirectional VT1.5 low-order ports, or
•2016 VT2 low-order ports, or
•1344 bidirectional VT1.5 ports and 1008 bidirectional VT2 ports (mixed grooming)
The TCC2/TCC2P card assigns bandwidth to each slot on a per STS-1, per VT1.5, or per VT2 basis. The switch matrices are fully crosspoint and broadcast supporting.
At the STS level (high-order cross-connect), the XC-VXC-10G is always non-blocking (any STS-1 from the system can be cross-connected to any other STS-1 without limitation up to 1152 bidirectional STS-1 ports (576 STS-1 cross-connects).
In addition, for "mixed" VT1.5 and VT2 grooming, 50% of the available VT resources (ports) are allocated to each VT circuit type. The following three modes are supported (only one mode is available at a time):
•Mode 1: full VT1.5 cross-connect, which is 2688 bidirectional VT1.5 ports (1344 bidirectional VT1.5 cross-connects)
•Mode 2: full VT2 cross-connect, which is 2016 bidirectional VT2 ports (1008 bidirectional VT2 cross-connects)
•Mode 3 (mixed grooming): 50% VT1.5 and 50% VT2 XC, which is 1344 bidirectional VT1.5 ports and 1008 bidirectional VT2 ports (672 bidirectional VT1.5 and 504 VT2 bidirectional cross-connects)
The XC-VXC-10G card provides:
•1152 STS bidirectional ports
•576 STS bidirectional cross-connects
•2688 VT1.5 ports via 96 logical STS ports
•1344 VT1.5 bidirectional cross-connects
•2016 VT2 ports via 96 logical STS ports
•1008 VT2 bidirectional cross-connects
•Mixed grooming (50% VT1.5 and 50% VT2)
•Nonblocking at the STS level
•VT1.5, VT2, and STS-1/3c/6c/12c/48c/192c cross-connects
Note VT 2 circuit provisioning works between optical cards and the DS3/EC1-48 card (EC1 ports, not the ports provisioned for DS3)
The XC-VXC-10G supports errorless side switches (switching from one XC-VXC-10G on one side of the shelf to the other XC-VXC-10G on the other side of the shelf) when the switch is initiated through software and the shelf is equipped with TCC2/TCC2P cards.
Cross-connect and provisioning information is established through the user interface on the TCC2/TCC2P card. In turn, the TCC2/TCC2P card establishes the proper internal cross-connect information and relays the setup information to the XC-VXC-10G card so that the proper cross-connection is established within the system.
The XC-VXC-10G card is deployed in Slots 8 or 10. Upgrading a system to an XC-VXC-10G from an earlier cross-connect module type is performed in-service, with hitless operation (less than 50-ms impact to any traffic). The XC-VXC-10G can be used with either the standard ANSI shelf assembly (15454-SA- ANSI) or high-density shelf assembly (15454-SA-HD).
Do not operate the ONS 15454 with only one XC-VXC-10G cross-connect card. Two cross-connect cards must always be installed.
Figure 2-8 shows the XC-VXC-10G cross-connect matrix.
Figure 2-8 XC-VXC-10G Cross-Connect Matrix
2.6.2 VT Mapping
The VT structure is designed to transport and switch payloads below the DS-3 rate. The ONS 15454 performs VT mapping according to Telcordia GR-253-CORE standards. Table 2-16 shows the VT numbering scheme for the ONS 15454 as it relates to the Telcordia standard.
2.6.3 XC-VXC-10G Hosting DS3XM-6 or DS3XM-12
A DS3XM card can demultiplex (map down to a lower rate) M13-mapped DS-3 signals into 28 DS-1s that are then mapped to VT1.5 payloads. The VT1.5s can then be cross-connected by the XC-VXC-10G card. The XC-VXC-10G card can host a maximum of 1344 bidirectional VT1.5s.
2.6.4 XC-VXC-10G Card-Level Indicators
Table 2-19 describes the two card-level LEDs on the XC-VXC-10G faceplate.
2.6.5 XC-VXC-10G Compatibility
The XC-VXC-10G card supports the same features as the XC10G card. Either the XC10G or XC-VXC-10G card is required for OC-192, OC3-8, and OC12-4 operation and OC-48 AS operation.
If you are using Ethernet cards, the E1000-2-G or the E100T-G must be used when the XC-VXC-10G cross-connect card is in use. When upgrading from an XC10G card to an XC-VXC-10G card, refer to the "Upgrade Cards and Spans" chapter in the Cisco ONS 15454 Procedure Guide for more information. Also refer to the "Card Compatibility" section.
2.7 AIC-I Card
Note For hardware specifications, see the "AIC-I Card Specifications" section.
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 through the backplane wire-wrap pin terminals. If you use the additional 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 2-9 shows the AIC-I faceplate and a block diagram of the card.
Figure 2-9 AIC-I Faceplate and Block Diagram
2.7.1 AIC-I Card-Level Indicators
Table 2-20 describes the eight card-level LEDs on the AIC-I card faceplate.
2.7.2 External Alarms and Controls
The AIC-I card provides input/output alarm contact closures. You can define up to twelve 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 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 the 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. You can program each of the sixteen input alarm contacts separately. Choices include:
•Alarm on Closure or Alarm on Open
•Alarm severity of any level (Critical, Major, Minor, Not Alarmed, Not Reported)
•Service Affecting or Non-Service Affecting alarm-service level
•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 unprovision the alarm input.
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 Not Reported, Not 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 network element (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.
2.7.3 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 signal) orderwire channels on an SDH 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. 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 bidirectional line switched rings (BLSRs) and path protection configurations.
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. 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.
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 by pressing *0000 on the DTMF pad. Individual dialing is initiated by pressing * and the individual four-digit number on the DTMF pad.
Table 2-21 shows the pins on the orderwire connector that correspond to the tip and ring orderwire assignments.

When provisioning the orderwire subnetwork, make sure that an orderwire loop does not exist. Loops cause oscillation and an unusable orderwire channel.
Figure 2-10 shows the standard RJ-11 connectors used for orderwire ports. Use a shielded RJ-11 cable.

2.7.4 Power Monitoring
The AIC-I card provides a power monitoring circuit that monitors the supply voltage of -48 VDC for presence, undervoltage, or overvoltage.
2.7.5 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 card. Use an unshielded RJ-11 cable. Each UDC can be routed to an individual optical interface in the ONS 15454. For UDC circuit provisioning, refer to the "Create Circuits and VT Tunnels" chapter in the Cisco ONS 15454 Procedure Guide.
The UDC ports are standard RJ-11 receptacles. Table 2-22 lists the UDC pin assignments.

2.7.6 Data Communications Channel
The DCC 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 DCCs, DCC-A and DCC-B, through separate RJ-45 connectors on the front of the AIC-I card. Use a shielded RJ-45 cable. Each DCC can be routed to an individual optical interface in the ONS 15454.
The DCC ports are synchronous serial interfaces. The DCC ports are standard RJ-45 receptacles. Table 2-23 lists the DCC pin assignments.
