as Figure 3-53 illustrates. A user may also retrieve performance monitoring statistics for a VC Group
rather than retrieving those same statistics for each of the several constituent STS-Nc subfacilities.
Figure 3-53 VC Groups
VC Groups, coupled with the TN-Connect connection routing feature, allow one-step provisioning of STS-
Nc-Xv connections across a network of Turin Networks systems. When a Gigabit Ethernet card or Fast
Ethernet PLM is inserted in a PLM slot, VC groups are automatically provisioned. They are labeled with
the AIDs of VC#V#-[AID]Autoprovision as described in Table 3-23 . VC connection can be made using
these VC groups or different VC groups can be created at different speeds.

A user may enter a single ENT-CRS-RTD TL-1 command to make an STS-Nc-Xv connection between
two GbE ports; to do this, the user enters the VC Group IDs of the two GbE ports as the two endpoints of
the routed connection in the ENT-CRS-RTD command.
3.10.10 Protected Ethernet (Enhanced GbE PLM)
The TE-206 already (R4.0) supports user provisionable equipment protection for GbE ports. Since most
applications involve using the TE-206 for access with the TE-2020 as a hub node, the lack of comparable
equipment protection on the TE-2020 E-GbE PLM leaves the feature only half finished.
The Ethernet protection feature involves the use of a 50/50 optical power tap (splitter/combiner) cable
