BLSR

•supports BLSR protocol on OC-192 circuit packs equipped with STX-192 circuit packs in slots 13 and 14.

•supports BLSR protocol on OC-48 circuit packs equipped with VTX-series circuit packs in slots 13 and 14.

—BLSR is not supported on OC-48 STS circuit packs equipped in slots 11 and 12.

•VT1.5, STS-1, STS-3c, and STS-12c, connections supported on the OC-48 BLSR ring equipped with VTX-series circuit pack.

•STS-1, STS-3c, STS-12c, STS-24c and STS-48c connections supported on the OC-192 BLSR ring equipped with STX-192 circuit pack.

•supports In service Channel Rollover and In service Route Rollover of VT1.5, STS-1, STS-3c, STS-12c and STS-24c.

Note 1: VT1.5connections require VTX-series circuit pack.

Note 2: STS-24c connections are supported on 2xGigE/FC-P2P, OC-48 STS and OC-192 circuit packs.

•supports OPE connections (RPR rings) at STS-1, STS-3c and STS-12c over OC-48 or OC-192 BLSR.

Connection editing

Connection editing for the optical interface allows the user to change traffic configurations through single or multiple connection type editing, while maintaining live traffic. A forced switch or lockout may be required before the edit to ensure that traffic is maintained.

In-service traffic rollover

In-service traffic rollover allows you to migrate live traffic within the transport network. You can migrate any cross-connect end point to any other end point capable of servicing the cross-connect rate, independent of the protection scheme at the end point.

This operation is also supported to provide reconfigurations, such as merging two UPSRs. This can be done on path-switched connections (1WAYPR and 2WAYPR) to move traffic from one cross-connect termination to a new termination without disrupting service.

In service Channel Rollover in BLSR networks is the act of moving VT or STS channels across time slots within a span. In service Route Rollover in BLSR networks is the act of moving VT or STS channels from the short path to the long path.

Note: In-service traffic rollover is not supported over RPR.
