<p>PURPOSE:To simplify hardware and software and to attain high processing capability by applying transmission reception of an intra-station signal between signal processing units by the same common line signal system as the inter- station signal system. CONSTITUTION:Signal processing units 10-1-10-n processing the No.7 common line signal system consists of level 2 processing sections 16-1-16-m, inter-station level 3 processing section 17 and an intra-station level 3 processing section 18. Each signal processing unit is connected by inter-device bus 14 and the intra-station signal between the units is sent/received. The processing of the intra-station signal transmission and reception between the signal processing units is conducted in the lump by the intra-station level 3 processing section, then the processing corresponding to the inter-equipment bus is not required for the inter-station level 3 processing section and only the No.7 common line signal system processing is required. Moreover, since the intra-station level 3 processing section has only to send the signal received from the signal link to the intra-station level 3 processing section having the same function and interface as its own protocol, no overhead of protocol conversion is required, and the the processing capability is improved.</p> |
