TCC-I Timing Communication and Control Card Description

The TCC-I performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SDH SOH Data Communications Channel (DCC) termination, and system fault detection for the ONS 15454 SDH. The TCC-I also ensures that the system maintains Stratum 3 E (G.813) timing requirements. Figure 1 shows the TCC-I faceplate and Figure 2 shows a block diagram of the card.

TCC-I Functionality

The TCC-I supports multichannel, high-level data link control (HDLC) processing for the DCC. Up to 48 DCCs can be routed over the TCC-I and up to ten DCCs can be terminated at the TCC-I (subject to available optical digital communication channels). The TCC-I selects and processes ten DCCs to facilitate remote system management interfaces.

The TCC-I also originates and terminates a cell bus carried over the module. The cell bus supports links between any two cards in the system, 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 TCC-I non-volatile memory, which allows quick recovery in the event of a power or card failure.

The TCC-I performs all system-timing functions for each ONS 15454 SDH. The TCC-I monitors the recovered clocks from each traffic card and two BITS ports for frequency accuracy. The TCC-I selects a recovered clock, a BITS or an internal Stratum 3 E 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-I to synchronize with the recovered clock, which provides holdover if the reference is lost.

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

The TCC-I uses a 10Base-T LAN port for user interfaces, being led via the back plane to the port accessible on the front panel of the MIC-C/T/P unit.

Note Cisco does not support operating the ONS 15454 SDH with only one TCC-I 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 TCC-I(s) card has reached the active/standby state. During transitional states such as power-up or TCC-I reset CTC ignores the FMEC inventory displayed in node view.

Note When a second TCC-I card is inserted into the shelf, it will synchronize its software, its backup software, and its database with the active TCC-I.
If its software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy from the active TCC-I. This copying will take about 15 to 20 minutes.
If its backup software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy the backup software from the active TCC-I. This copying, again, will take about 15 to 20 minutes.
Copying the database from the active TCC-I will take about 3 minutes.
So, depending on the software existing in the new TCC-I, booting it up will take between 3 and about 40 minutes.

TCC-I Card-Level Indicators

The TCC-I faceplate has eight LEDs. The first two LEDs are card-level indicators.

Table 1 TCC-I Card-Level Indicators

Card-Level LEDs

Definition

Red FAIL LED

This LED is lit during Reset. The FAIL LED flashes during the boot and write process. Replace the unit if the FAIL LED persists.

ACT/STBY LED

Green (Active)

Yellow (Standby)

The ACT/STBY (Active/Standby) LED indicates the TCC-I is active (green) or in standby (yellow). The ACT/STBY LED also provides the timing reference and shelf control. When the TCC-I is writing to the Active or Standby TCC-I, its Active or Standby LED will blink. Do not pull the TCC-I out during this time to avoid memory corruption.

Network-Level Indicators

The TCC-I faceplate has eight LEDs. Six LEDs are network-level indicators.
