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