TCC/DTI Card
The Cisco RFGW-10 UEQAM supports two Timing, Communication, and Control (TCC) slots. The
TCC card acts as a secondary processor that controls the overall system clock generation and
distribution, DOCSIS timestamp synchronization, and system control of the Front Panel Display (FPD)
and the RF Switch cards.
The TCC card’s most critical function is distribution of the system clocking, in particular the DTI
interface. The TCC card is a DTI client interface. It supports dual DTI external input allowing DTI server
redundancy. Based on the DTI input information, the TCC card generates DOCSIS 10.24-MHz clock and
timestamp information to every line card in the chassis. All clocks and DOCSIS information are
redundant. When there is no external DTI clock, the TCC provides an internal DOCSIS DTI clock and
time stamp reference.
When two TCC cards are installed, they are configured as active and backup (redundant). If the TCC
card in the first slot is working at system power-up, it automatically becomes the active card and the TCC
card in the second slot becomes the backup card (typically Slot 13 boots as the primary TCC and Slot
14 as the secondary, but this is not mandatory).
