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. 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.

TCC-I Timing Communication and Control Card Description
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
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.

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.

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. Plug the wristband cable into the ESD jack located on the lower right outside edge of the shelf
assembly and ensure the shelf assembly is properly grounded.
Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution
when servicing.
Step 1 Open the card ejectors.
Step 2 Carefully insert the card into the guide rails of the desired slot (Figure 3 on page 6). The TCC-I card
has to be inserted into slot 7 or slot 11.
Step 3 Push the card into the connector on the back plane by closing the ejectors.

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. Replace the unit if the faulty state persists.
Verify Successful Turn Up of the TCC-I Card
Step 1 Verify that power is applied to the shelf assembly.
Step 2 Verify that the TCC-I card has been installed in the correct slot (Slot 7 or slot 11).
Note The TCC-I card takes several minutes to reboot and display the amber standby LED after rebooting.
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.
Removal Procedures
Step 3 Verify that the card appears in the correct slot on the CTC software screen.
Step 4 Verify that the card is white on the CTC software screen.
Step 5 Verify that the card is shown in Inventory on the CTC software screen.
Removal 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. Plug the wristband cable into the ESD jack located on the lower right outside edge of the shelf
assembly and ensure the shelf assembly is properly grounded.
Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution
when servicing.

Removal Procedures
Note To determine whether the TCC-I card is in active mode or standby mode, view it in the CTC software
and position the cursor over the TCC-I card graphic to display the status.
Step 1 If you need to perform a card pull on an active TCC-I card, initiate a software reset on the active TCC-I
card first. (See the “Initiate a Software Reset” section on page 8).
Step 2 When the TCC-I is in standby mode, unlatch the top and bottom ejector levers on the TCC-I card.
Step 3 Carefully remove the card from the shelf.
Initiate a Software Reset
Step 1 Log into the CTC software.
Step 2 Right-click the TCC-I card to reveal a pull-down menu.
Step 3 Click Reset Card. (See Figure 4).
