The TN777B communicates control channel messages between the Processor circuit pack and the distributed network of port circuit packs on the Time Division Multiplexing (TDM) bus. The circuit pack also controls the four data channels that process and route information directly from the Processor circuit pack to customer-connected equipment. Some of the possible equipment connections are data services facilities, Call Detail Recording devices, an on-premises remote pooled modem or administration terminal, or an off-premises administration terminal. Some of these connections require modems such as a Modular Processor Data Module (MPDM) or a Modular Trunk Data Module (MTDM). The TN777B has the time-of-day clock with battery backup for power failure or low voltage conditions. This circuit pack also has a 24-hour clock used with record keeping and system maintenance. The TN777B monitors the status of the system clocks and alerts the Processor circuit pack in the event of a failure of any clock. The TN777B supports the high reliability option and handles all the control channel messages from the PPN or EPN networks over the TDM. This circuit pack uses an AT&T Memory Card (flash card).
