BLSR (Node View)
(ONS 15327, ONS 15454, and ONS 15600 node view only) Use the node view BLSR tab to view node bidirectional line switched ring (BLSR) information including the ring name, ring type (two-fiber or four-fiber), status, the node's BLSR ID, any active ring or span reversions, and the node's east and west spans. For ONS 15327, ONS 15454, and ONS 15600 nodes, you can create, delete, and edit two-fiber BLSRs. For ONS 15454 nodes, you can convert two-fiber BLSRs to four-fiber BLSRS and create four-fiber BLSRs.
Displays the BLSR Creation wizard, where you can create a new BLSR.
Displays the BLSR squelch table. The table shows STSs that will be squelched for every isolated node. The STSs are replaced by the appropriate Path AIS to prevent misconnections. For more information about BLSR squelching, see Telcordia GR-1230.
Displays the BLSR ring interworking on protection (RIP) table. The secondary node maintains a RIP table that contains, for each incoming and outgoing inter-ring circuit carried on the protection bandwidth, the source or terminating node address and the primary node address.
(ONS 15454 only) If the highlighted BLSR is two-fiber, the button allows you to upgrade the BLSR to a four-fiber BLSR.
Cancels any BLSR subtab changes and returns the fields to their last-saved settings.
