摘要

The monitoring system verifies the channel status signals, for free or occupied indication associated with each transmission channel between the peripheral stationspral sa (BLMC) and the central star point (gs). Only when a status signal for an occupied indication is received is the corresponding information signal processed, otherwise the transm'ssion channel is blocked for signal reception at the star point (gs). Pref. the status signals are defined by the parity bits for each information signal transmitted in conjunction with the information signal words.
