Abstract :
A low-power CMOS line circuit board controller for digital exchanges will be covered in this report. The device (35mm2) interfaces 16 subscriber line circuits to two independent exchange processors. System provides packet data line control, event-based subscriber signaling, and analog PLL-based clock synchronization.
