STS-3c Cross-Connects
8
The 0x1 OC-3c optical interface provides the ability of transporting STS-3c
services on OC-3c low-speed function units optical interfaces that have been
provisioned for 0X1 applications. The internal system’s application default value
for OC-3 OLIU (22-type) in the function unit is “0x1”. The CIT
ent-crs-sts3c
command is used with a two-way cross-connect type option.
