In service route rollover
A user can move VT or STS channels onto an alternate span.

Retrieving, adding, editing and deleting BLSR protection
A user can provision and deprovision an optical facility to be BLSR-protected.
Retrieving, adding, editing, deleting a non-RPR nodal cross-connect
A user can add, edit or delete a non-RPR cross-connect involving
BLSR-protected optical facilities as AIDs.
Retrieving, adding and deleting an End-to-End Connection over BLSR
Site Manager Release 6.0 supports end-to-end connection provisioning over
BLSR. Users can choose ‘Long’ or ‘Short’ path around the ring.
Note: OPE end-to-end connections are not supported.
Adding and deleting a BLSR configuration
A user can add or delete a BLSR Configuration to/from the NPx.
The operation of adding involves the creation of a ‘temporary configuration’
to which a user may add or edit BLSR configuration attributes. At any point
before ‘committing’ a BLSR configuration to the NPx, a user may ‘cancel’ the
operation, thereby backing out of the entire procedure. When the user is
comfortable with the provisioned attributes of a ‘temporary configuration’, the
user may then ‘commit’ that configuration to the NPx and to the remaining
nodes (SPx circuit packs) in the BLSR ring. The BLSR configuration stored
on the NPx is considered by the system to be the master copy.
The operation of deleting requires that the user:
• delete all connections
• remove the entire BLSR configuration
Forcing a BLSR configuration / connection audit
BLSR configuration / connection audits can be run on demand from the NPx.
Audits can only take place if the NPx Provisioning State is IDLE.
