Arrangement for synchronization of multiple streams of synchronous traffic delivered by an asynchronous medium

摘要: An ATM cell constructor (100) of an transmitter assembles a stream frames constant bit-rate traffic received on listen TDM bus (102) into payloads (1104) using adaptation layer 1 (AAL1). Once every eight cells, the AAL1 structured data transfer (SDT) (112) introduces one-octet SDT offset pointer (1120) payload. This designates traffic-block (TDM frame) boundaries. The payload with attached header forms cell, and transmits cells to deconstructor (2100) receiver. disassembles talk (102). In response each pointer, deconstructor's time slot interchanger (TSI 2108) resets start frame-processing, thereby aligning formed by TSI frames. (2100:2104) detects occurrence synchronizes (aligns) transmission bus. buses are synchronized other.
