Abstract:
1. A bus control module as a terminal stage in a multi-stage distribution system disposed in a signaling server operating as a Signal Transfer Point in a telecommunications network, comprising: decoding circuitry to decode a framed control signal received from an upstream stage of said multi-stage distribution system; a status generator receiving a plurality of status signals from at least one line interface card disposed on a bus segment and controlled by said bus control module, said status generator for encoding said status signals in a predetermined frame of a framed serial status bitstream based on control data obtained from said framed control signal; and a Phase Lock Loop (PLL) module to lock on an incoming system clock signal received from said upstream stage of said multi-stage distribution system, said PLL module generating a copy of said system clock to be provided to said at least one line interface card.
