2.1  Common Control Card Overview

The cards for the ONS 15454 SDH include front mount electrical connection (FMEC) cards, common control cards, electrical cards, optical cards, and Ethernet cards. Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 SDH shelf assembly. The cards are then installed into slots displaying the same symbols (refer to the Cisco ONS 15454 SDH Procedure Guide for a list of slots/symbols). The overview in this section provides a summary of the cards.

Note The ONS 15454 SDH is a flexible metro optical transport system supporting a wide variety of applications. The power consumption of the shelf assembly varies depending upon shelf configuration. Design your power distribution network based on your maximum ONS 15454 SDH system power draw, or the ONS 15454 SDH's maximum rated shelf power draw.

If you select to design your power plant to your maximum planned ONS 15454 SDH system configuration, the Cisco ONS 15454 SDH Reference Manual lists the power consumption for each card that can be used to determine your maximum ONS 15454 SDH system power draw. The general guideline for fuse selection is 20 percent above the maximum calculated system power draw.

If you design your power system to the ONS 15454 SDH's maximum rated shelf power draw, Cisco recommends that you select a power distribution system supporting a minimum capacity of 30 A for each A and B power feeder on each ONS 15454 SDH shelf assembly. Feeder lines should be fused at 30 A. This recommendation is based on the shelf assembly's current rated maximum power draw of 30 A at -48 VDC. The maximum power draw configuration on the ONS 15454 SDH, based on the hardware available with Release 4.0, requires 30 A at -48 VDC.


2.2  Advanced Timing Communications and Control (TCC2) Card

The TCC2 performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SDH section overhead (SOH) data communications channel/generic communication channel (DCC/GCC) termination, and system fault detection for the ONS 15454 SDH. The TCC2 also ensures that the system maintains Stratum 3 (ITU-T G.812) timing requirements. It monitors the supply voltage of the system.


Note The TCC2 card can work with the XC10G, XC-VXL-10G, or XC-VXL-2.5G cross-connect cards. It requires Software Release 4.0.0 or later.



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



Note The TCC2 has been designed to support both -48 VDC and -60 VDC input requirements.


Figure 2-1 shows the TCC2 faceplate.

Figure 2-2 TCC2 Block Diagram

2.2.1  TCC2 Functionality

The TCC2 supports multichannel, high-level data link control (HDLC) processing for the DCC/GCC. 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 SDH. The TCC2 monitors the recovered clocks from each traffic card and two building integrated timing supply (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 10BaseT LAN interface and an EIA/TIA-232 ASCII interface for local craft access. It also has a 10BaseT LAN port for user interfaces via the backplane to the port accessible on the front of the MIC-C/T/P FMEC.


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



Note CTC software does not monitor for the presence or absence of FMECs unless the TCC2 card(s) have reached the Active/Standby state. During transitional states such as power-up or TCC2 reset, CTC ignores the FMEC inventory displayed in node view.



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

Table 2-3 describes the two card-level LEDs on the TCC2 faceplate.

Table 2-3 TCC2 Card-Level Indicators  

Card-Level LEDs

Green RING LED

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


2.6.2  User-Defined Alarms

The AIC-I card provides input/output alarm contact closures. You can define up to 16 external alarm inputs and four external alarm inputs/outputs (user configurable). The physical connections are made using the MIC-A/P. The alarms are defined using CTC. For instructions, refer to the Cisco ONS 15454 SDH Procedure Guide.

LEDs on the front panel of the AIC-I indicate the status of the alarm lines: one LED representing all the inputs and one LED representing all 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 sixteen 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), 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 unprovision 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, as follows:

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 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.

2.6.3  Orderwire

Orderwire allows a craftsperson to plug a phone set into an ONS 15454 SDH and communicate with craftspeople working at other ONS 15454 SDHs or other facility equipment. The orderwire is a pulse code modulation (PCM) encoded voice channel that uses E1 or E2 bytes in the multiplex section overhead and in the regenerator section 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 SDH facility. The ONS 15454 SDH 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 multiplex section-shared protection ring (MS-SPRing) and subnetwork connection protection (SNCP).


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

The ONS 15454 SDH 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/STM-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 (EOW) channel.


The AIC-I supports selective dual tone multifrequency (DTMF) dialing for telephony connectivity which causes specific or all ONS 15454 SDH AIC-Is 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.

The orderwire ports are standard RJ-11 receptacles. The pins on the orderwire ports correspond to the tip and ring orderwire assignments. Table 2-9 describes the orderwire pin assignments.

2.6.4  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 SDH network. Each AIC-I card provides two UDCs, 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 SDH system. For instructions, refer to the Cisco ONS 15454 SDH Procedure Guide.

The UDC ports are standard RJ-11 receptacles. Table 2-10 lists the UDC pin assignments.

2.6.5  Data Communications Channel/Generic Communication Channel

The data communication 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 SDH network. Each AIC-I card provides two DCC/GCCs, 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 SDH system. For instructions, refer to the Cisco ONS 15454 SDH Procedure Guide.


Note DCC/GCC connection cannot be provisioned if DCC/GCC tunneling is configured on this span.


The DCC/GCC ports are standard RJ-45 receptacles. Table 2-11 describes the DCC/GCC pin assignments.
