METHOD AND APPARATUS FOR EGRESS CHANNEL ARCHITECTURE THAT SUPPORTS PROTECTION WITHIN SONET/SDH BASED NETWORKS

摘要

A channel (412) is described that has a backplane interface unit (401) that selects a signal (406) from a backplane. The backplane interface unit is coupled to a cross connect table (411) that provides an indication (450) where the signal may be found on the backplane. The indication is correlated to a logical label. The logical label is correlated to a frame location (402) that the selected signal is transmitted within.
