STS-3c Video Application ATM Interface
2
Figure 2-21 shows the video application for the DDM-2000 OC-12 ring used to
transport STS-3c signals from one ATM switch to another. In this scenario, each
OC-12 shelf is cross-connected and provisioned as COV type. This provides the
capability of transmitting a point-to-point STS-3c video signal from one shelf to
another. 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.

Customer experience with this application has revealed compatibility issues with some
brands of ATM equipment (e.g., Cisco, Bay Network). For ATM support it is strongly
recommended to use the STS-3c 0x1 application features provided in OC-12 Release 5.2
and later ring releases, unless an unprotected scheme is acceptable.
