TELEPHONE NETWORK SYSTEM USING WIRELESS LOCAL LOOP SYSTEM AND TRANSMISSION LINE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a telephone network system using a wireless local loop system realizing high speed data communication and to provide the transmission control method. SOLUTION: The subscriber setting table of an encoding system based on the use form of a transmission line is registered at every subscriber. At the time of allocating the subscriber system transmission line, a switch control circuit 90 and a switch control circuit 100 respectively change over an encoding system switch 44 and an encoder/decoder switch 54 based on the subscriber setting table stored in a storage device 92. A bypass route 42 through which a PCM signal passes is selected in WAC 80 and a PCM encoder/decoder 52 in WSU 82 for the subscriber executing data communication. The encoding system of the transmission line is set to a PCM system executing high speed data communication.
