    • PURPOSE: A guide broadcast transmission apparatus when V5.2 interface relay line is over congested, is provided to set up a certain channel based on a pre-allocation function for implementing a guide broadcast transmission function even when a V5.2 interface relay line is over congested for thereby using the set channel for only a guide broadcast. CONSTITUTION: A guide broadcast transmitter(60) is installed outside a V5.2 related system of a digital full electronic switch, and stores an over-congestion related automatic guide broadcast audio data for transmitting a guide broadcast to a system which requests a guide broadcast and reproduce guide broadcast audio data when control information is received and transmits to a guide broadcast matching unit(50). The guide broadcast matching unit(50) transmits guide broadcast data generated by the guide broadcast transmitter(60) to a call controller(20) of the system. The call controller(20) controls a guide broadcast connection and disconnection function so that the guide broadcast audio data are connected with a guide broadcast channel. A V5.2 time slot management unit(10) previously allocates a guide broadcast channel for transferring the guide broadcast audio data to the V5.2 interface unit(40). The V5.2 call processor(30) performs a switching function for carrying the guide broadcast audio data on a guide broadcast time slot of a corresponding E1 trunk.
