Control processor of access network system and method for expanding capacity of subscriber channel in the processor

摘要

PURPOSE: A control processor of an AN(Access Network) system and a method for expanding a subscriber capacity thereof are provided to apply a TSW(Time SWitch) in a front-end of a subscriber unit, without using the concept of an expansion shelf, so as to expand the subscriber capacity in a shelf. CONSTITUTION: A framer unit(310) processes the transceiving of data frame information delivered from a synchronous transmission module. A TSA(Time Slot Assign) unit(320) assigns a time slot between the framer unit(310) and a subscriber unit(340), to provide a function to connect and disconnect a speech path. A TSW unit(330) arranged between the TSA unit(320) and the subscriber unit(340) provides a concentration function of time slot connection and disconnection when a subscriber attempts or ends a call service. The subscriber unit(340) provides the time slot for connection and disconnection according to subscriber ports in the TSW unit(330). And the subscriber unit(340) receives the assigned time slot in an idle state on data stream between the TSA unit(320) and the TSW unit(330) when a subscriber attempts a call, and provides the assigned time slot to a subscriber unit connected to the subscriber.
