Table 3-22 Fast Ethernet PLM Cross-connect and VC group types
The actual connection on the node is made from a GbE port to another GbE port, or a GbE port to an STS-
1, OC-3, OC-12, OC-48 port, or OC-192 port. An intermediate node that does not have an ethernet inter-
face could have a VC group connection from SONET port to SONET port. As a result, VC groups can be
created on all Ethernet and SONET facilities on the node.
Figure 3-51 Virtual Concatenation Example
STS-3c-Nv N Virtually concatenated STS-3cs using a VC group; N = 1..7
NOTE: An STS-3c-1v is a single STS-3c VC group. It is not the same as using a single
STS-3c (H4 SONET overhead byte is different). A user may choose this option if the
initial signal is a single STS-3c but in the future may grow to multiple STS-3cs. The VC
group could then be modified.
Nomenclature Contents
STS-1 A single STS-1. No Virtual Concatenation is used. The user should select the STS-1 signal
type not the VC signal type to implement this connection.
STS-1-1v A single STS-1 but using a VC group. A user may choose this option if the initial signal is a
single STS-1 but in the future may grow to multiple STS-1s. The VC group could then be
modified.
STS-1-2v 2 Virtually concatenated STS-1s using a VC group. This is line rate for Fast Ethernet.
