TCC-I Timing Communication and Control Card Description 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.
TCC-I Timing Communication and Control Card Description Figure 2 TCC-I block diagram Flash 10BaseT Processor Modem Ethernet Timing Flash Controller 10BaseT Control Processor Craft Framer/ Message TDM/SCC Mux Router Crossconnect 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).
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. CTC software does not monitor for the presence or absence of FMECs unless the TCC-I(s) card has Note reached the active/standby state.
TCC-I Timing Communication and Control Card Description Table 2 TCC-I System-Level Indicators System-Level LEDs Definition Red CRIT LED Used to indicate critical alarms in the network at the local terminal. Red MAJ LED Used to indicate major alarms in the network at the local terminal. Yellow MIN LED Used to indicate a minor alarm in the network at the local terminal.
Installation Procedures Installation Procedures Use this section if you are installing or removing the TCC-I card for the first time. After you become familiar with ONS 15454 SDH card installation and boot up, use this section as a reference. Caution Always use the supplied electrostatic discharge (ESD) wristband when working with an ONS 15454 SDH.
Removal Procedures Card Turn Up Follow the steps in this section to verify card turn up. If one or more of the Cisco Transport Controller (CTC) software screen conditions according to “Verify Successful Turn Up of the TCC-I Card” section on page 7 are not met, re-install the card.
Removal Procedures To determine whether the TCC-I card is in active mode or standby mode, view it in the CTC software Note and position the cursor over the TCC-I card graphic to display the status. If you need to perform a card pull on an active TCC-I card, initiate a software reset on the active TCC-I Step 1 card first.
