16.2.2 TCC2P Card
16.2.2 TCC2P Card
The Advanced Timing, Communications, and Control Plus (TCC2P) card is an enhanced version of the
TCC2 card. The primary enhancements are Ethernet security features and 64K composite clock BITS
timing.
The TCC2P card performs system initialization, provisioning, alarm reporting, maintenance,
diagnostics, IP address detection/resolution, SONET SOH DCC/GCC termination, and system fault
detection for the ONS 15454. The TCC2P 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 TCC2P 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).
The interfaces can operate with a cable length of 32.8 ft (10 m) maximum at temperatures from –40 to
32 degrees Fahrenheit (–40 to 0 degrees Celsius).
shows the faceplate and block diagram for the TCC2P card.
