2.1.1 Common Control Cards
The following common control cards are needed to support the functions of the DWDM, transponder,
and muxponder cards:
• TCC2 or TCC2P
• AIC-I (optional)
• MS-ISC-100T (multishelf configurations only)
2.1.2 Front Mount Electrical Connections (ETSI only)
The following Front Mount Electrical Connections (FMECs) are needed to support the functions of the

2.2 TCC2 Card
Note For TCC2 card specifications, see the “A.3.1 TCC2 Card Specifications” section on page A-8.
The Advanced Timing, Communications, and Control (TCC2) card performs system initialization,
provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SONET
section overhead (SOH) data communications channel/generic communications channel (DCC/GCC)
termination, optical service channel (OSC) DWDM data communications network (DCN) termination,
and system fault detection for the ONS 15454. The TCC2 also ensures that the system maintains
Stratum 3 (Telcordia GR-253-CORE) timing requirements. It monitors the supply voltage of the system.
Note The LAN interface of the TCC2 card meets the standard Ethernet specifications by supporting a cable
length of 328 ft (100 m) at temperatures from 32 to 149 degrees Fahrenheit (0 to 65 degrees Celsius).
Figure 2-1 shows the faceplate and block diagram for the TCC2.
