摘要: A configuration for a SONET transport node comprises pair of transparent mux/demuxs provided at two sites and connected over high rate span. The T-Muxs provide continuity all tribs maintain lower bit linear or ring system through the higher operates as if it were directly without midsection. For forward direction traffic, T-Mux multi-channel receiver receiving trib signals providing each signal SPE OH. SPEs are multiplexed into supercarrier OHs processed to generate transmitter maps OH transmits same Reverse operations effected reverse traffic. With this invention, an entire does not have be upgraded line due fiber exhaust on single invention is particularly applicable OC-48/OC-12/OC-3 networks span could OC-192 line.
