Sistema de transmissão por fibra ótica e processo para interconectar primeiro e segundo anéis de rede ótica síncrona (sonet)

摘要

A pair of SONET rings (12' and 14') can be interworked by providing at least two gateways (16m-1 and 16m) that are shared by each of the rings. Each shared gateway has the capability of transferring a block of optical information resident in a prescribed time slot in an interchange frame associated with one ring to a time slot in an interchange frame associated with the other ring so the block reaches its intended destination in that ring.
