12.12.4 Two-Fiber BLSR to Four-Fiber BLSR

CTC provides a wizard to convert two-fiber OC-48 or OC-192 BLSRs to four-fiber BLSRs. To convert
the BLSR, you must install two OC-48 or OC-192 cards at each two-fiber BLSR node, then log into CTC
and convert each node from two-fiber to four-fiber. The fibers that were divided into working and protect
bandwidths for the two-fiber BLSR are now fully allocated for working BLSR traffic.

12.12.5 Add or Remove a Node from a Topology

You can add or remove a node from a linear ADM, BLSR, or path protection configuration. Adding or
removing nodes from BLSRs is potentially service affecting; however, adding and removing nodes from
an existing 1+1 linear ADM or path protection configuration does not disrupt traffic. CTC provides a
wizard for adding a node to a point-to-point or 1+1 linear ADM. This wizard is used when adding a node
between two other nodes.
