This solution features similar benefits to the GbE private line solution: a cost-effective way to deliver
Ethernet-based services and traditional circuit services at an end user location, plus the survivability, man-
ageability, interoperability, and reliability that SONET transport affords.

3.10.3 GbE Ethernet Video Distribution
Figure 3-46 shows how nodes equipped with GbE PLMs can provide Gigabit Ethernet based video distri-
bution. In this application there is a video server that needs to deliver video to multiple ring sites. The
video server interface is Gigabit Ethernet. Using a combination of Line rate Virtual Concatenation and
SONET drop-and continue, a one-way connection is created around the SONET ring dropping the same
Gigabit Ethernet signal at each required site. On the ring, the gigabit ethernet connection, regardless of the
number of drop sites, would consume 21 STSs in the form of 7 Virtually Concatenated STS-3cs. The video
connection is ring protected as well.

3.10.4 Bulk Interoffice GbE Transport
Figure 3-47 shows how TE-2020 nodes equipped with GbE PLMs can provide bulk, point-to-point GbE
transport between service provider locations. In this example, the TE-2020 nodes aggregate line-rate GbE
traffic, possibly in conjunction with other circuit traffic (the lower pair of TE-2020 nodes), onto OC-192
links. In this application, the TE-2020 can cost-effectively aggregate traffic from eight GbE ports onto a
standard OC-192 in just two rack units (3.5") of rack space. The TE-2020 can optionally provide SONET
