Collocated OPTera Metro 3000 NE and shared VT-managed STS

A connection that uses a collocated OPTera Metro 3000 NE and shared VT-managed STS has the advantage of not requiring dedicated STS at each site, resulting in more efficient use of bandwidth at the edge. See Figure 2-71 on page 2-187.

With this type of connection, you can use multiple virtual rings at the edge with each virtual ring covering a different physical route and having different termination points. Each virtual ring can operate at STS-1 or higher bandwidth. See Figure 2-72 on page 2-188.

As with the option described in the previous section, this connection is a modular network design with low initial costs and allows efficient bandwidth utilization of the OPTera Metro 3500 STS-managed backbone network.
