Video Conferencing
9161-A2-GH30-40
The OCU-DP APM supports Switched 56 video as shown in the following
example. Here, an external video codec is connected to OCU-DP ports using
external Switched 56K DSU/CSUs. This connection can be up to 18,000 feet. The
OCU-DP APM converts the 56K digital format from the line side into a digital DS0
format. This DS0 format contains the 56K of data plus the necessary signaling
information required to set up the call to the far-end video equipment.
