The RASM structure of the electronic exchanger before the national government (REMOTE ACCESS SWITCHING MODULE STRUCTURE OF FULL ELECTRONICS SWITCHING SYSTEM)

摘要

The present invention relates to a RASM structure of a pre-service electronic exchange, comprising a first module (10) for performing an in-test and an out test on an analog subscriber and a digital subscriber, a second module A third module 14 for controlling the ring relay of the subscriber circuit as well as supplying the call signal current required for the subscriber circuit to the first module 10 and the second module 12, A fourth module 16 for performing registration and signal processing with the host, a fifth module 18 for performing digital trunk matching, a sixth module 20 for performing digital subscriber monitoring / control / maintenance / ), A seventh module (22) that matches the first-group access ISDN subscriber, an eighth module (24) that matches the first-order multiplexer to the exchange, and a transmission characteristic test A ninth module 26 for performing SRA An eleventh module 30 for providing a network synchronization service, a twelfth module 32 for performing a subscriber recording guidance service, a tenth module 30 for performing a signal service for call connection and progress, 13 module 34, a 14th module 36 for performing real-time processing of signals from device devices, a 15th module 38 for providing a control communication channel between the 14th module 36 and the control device, A 16th module 40 for performing call processing, operation and maintenance, control of peripheral devices, a seventeenth module 42 for exchanging interprocessor communication messages, multiplexing and demultiplexing of PCM data, The nineteenth module 46 performing the time slot interchanging operation and the twentieth module 48 performing the packet service so that the load sharing of the INP in the INS The number of processors can be greatly reduced, and more The control packet service is able to process while still enabling faster reliability.
