FULL ELECTRONIC EXCHANGE HAVING CALLER ID PRESENTATION SERVICE FUNCTION

摘要

PURPOSE: A full electronic exchange having a caller ID presentation service function is provided to display a call ID such as a caller number and name to a called call to a termination-side subscriber by mounting 2 sheets of circuit pack for the caller ID presentation service on an LSI(Local Service Interface). CONSTITUTION: An upper processor(ASP(Access Switching Processor)) and an internal fault sensing block(FI(Fault Interface)) are composed in the first shelf(S0). A block(CI(Control Interworking)) for supporting a communication between the upper processor(ASP) and a lower processor and a CIP(Control Interworking Processor) for controlling the block(CI) are composed in the second shelf(S1). A block(LSI) for transmitting a tone, a block(CSI(Caller Identity Delivery Service Interface)) for generating an FSK(Frequency Shift Keying) signal corresponding to a caller ID and outputting the FSK signal, and a lower processor(LSP(Local Service Processor)) for controlling the block(CSI) are composed in the third shelf(S2). A block(TEC(Test Equipment Control)) for testing a line, a lower processor(ASMP(Access Switching Maintenance Processor)) for controlling the block(TEC), and an RG(Ring Generator) are composed in the fourth and fifth shelves(S3,S4). An internal fault sensing block(FI) is composed in the sixth shelf(S5). An ASICR(Analog Service Interface Control Ract) controls an ASS-S(Access Switching Subsystem-Subscriber) and transmits various tones, ring sounds and the FSK signal corresponding to the caller ID.
