On the Cisco uBR10012 universal broadband router, the DTCC card acts as a secondary processor that performs the following functions:
In the default DTI mode, a 10.24 MHz clock and 32-bit DOCSIS timestamp are generated by the DTI Server, propagated to DTI client using DTI protocol, and distributed by DTI client to each cable interface line card.
Allows software to independently power off any or all cable interface line cards.
Drives the LCD panel used to display system configuration and status information.
Monitors the supply power usage of the chassis.
Two RJ-45 cables with the DTI server, which, in turn, can generate the clock using its own oscillator or external timing reference inputs such as GPS or network clock.
