5.
NOTE:
Ring releases support only manual VT1.5 and STS-1
cross-connections. Manual STS-1 and/or DS1
cross-connections have to be made at each shelf to
configure the transmission path for each DS3/DS1 circuit
being established. Either terminating (drop)
cross-connections or "drop and continue" cross-connections
are made at terminating nodes and pass-through
cross-connections are made at intermediate nodes.
From work order or rtrv-crs-( ) command, determine the
cross-connections for circuit being discontinued.
6.
!
CAUTION:
Removing the wrong cross-connection may cause service
interruption. Use the
rtrv-crs-( )
command to
determine the proper cross-connections.
NOTE:
DS1 LOW SPEED slots cannot be unequipped without an
alarm until all port cross-connections are removed. The
cross-connections must be removed first before removing
circuit packs. In a ring configuration, remove the
cross-connections from the terminating nodes first, then
remove the pass-through cross-connections at the
intermediate nodes. A Major alarm may occur when the first
cross-connection at the terminating node is deleted and
clear when the other terminating cross-connection is
deleted.
