In network view, double-click a BLSR node with OC-48 AS trunk (span) cards that will be reconnected
Step 1
after a BLSR node removal.
Double-click one OC-48 AS BLSR trunk card.
Step 2
Click the Provisioning > Line tabs.
Step 3
Record on paper the byte in the BLSR Ext Byte column.
Step 4
Repeat Steps
Step 5
Step 6 If the node at the other end of the new span contains OC-48 AS trunk cards, repeat Steps
the node. If it does not have OC-48 AS cards, their trunk cards are mapped to the K3 extension byte.

Note The Cisco OC-3 IR/STM-1 SH, OC-12 IR/STM-4 SH, and OC-48 IR/STM-16 SH interface optics, all
working at 1310 nm, are optimized for the most widely used SMF-28 fiber, available from many
suppliers.

This task verifies that the extension byte mapping is the same on BLSR
trunk (span) cards that will be connected after a node is removed from a
BLSR.
OC-48 AS cards must be installed at one or both ends of the BLSR span
that will be connected.
