STS-3c Video Broadcast Application
2
Video applications are becoming increasingly more important in the competitive home
entertainment industry. The DDM-2000 OC-12 Multiplexer can be the backbone for
video distribution needs as it supports two STS-3c video cross-connection types:
■
COV - Video cross-connections at central offices
■
RTV - Video cross-connections at remote terminals
Figure 2-20 shows the video broadcast application for the DDM-2000 OC-12
Multiplexer. In this application, incoming STS-3c signals at a "head-end" (cross-
connection type COV) OC-12 shelf are simultaneously dropped at any number of
remote OC-12 terminals (cross-connection type RTV). This provides the capability of
simultaneously transmitting up to eight STS-3c video feeds (using both slots of fn-A/B/C
and D, when equipped with OC-3 or IS-3 interfaces) to remote sites.
Significant features of this application are:
■
Both inner and outer rings (mb1 and mb2) distribute up to four STS-3c
unprotected one-way signals. These signals are then connected to OC-3 or IS-3
circuit packs.
■
The STS-3c signals can be provisioned in pairs (two, four, six, or eight) and
unused time slots can be used for other ring applications.
