Abstract
Each node ( ) of a SONET bidirectional line switch ring (BLSR)( ) generates a squelch table. Squelch table generation does not require a separate computer connected to the node. Each node also generates a payload table indicating a type of a synchronous transport signals (STS) on each link ( ) in the ring. The payload table allows each node to quickly determine the STS type on the protection channels when a ring switch occurs.
