Administration and Provisioning
Issue 8.0 July 2002

â– The VMR Mode parameter (DS3 signals only) for the through-connected
STS-1 tributaries should be provisioned as follows:
â– The incoming and outgoing Path Traces (DS3 signals only) should be the
same for through-cabled STS-1 tributaries; otherwise, a protected node
failure would create a path trace mismatch.
â– All through-cabled connections must have the same time slot assignments
on both sides of the FT-2000 OC-48 Add/Drop-Rings Terminal (for
example, no rearrangement of the STS-1s within the STS-3 or
rearrangement of STS-3s within the STS-48 is allowed for through
connections).
