The APEX supports reception of DTA in-band messages on any of the Host Fast Ethernet
(FE) Interfaces. When CAT and EMM messages are received, they are re-inserted onto
an output stream under the following conditions:
•
The output stream must be active, and DTA Support must be enabled for that output
stream.
•
The output transport stream is not configured for stream pass through.
•
The CAT PID, NET PID, and EMM PID must not be currently mapped from an input
to that output.
•
The multicast group for CAT/EMM PID and Network PID are not used by other
manual routings.
If any of the conditions mentioned above is not met, then the APEX removes existing
routings and displays an error message for the operator to perform the corrective action.
DTA Configuration (General)
To begin configuring DTA support, click Configuration > DTA Configuration.
The DTA General Configuration screen displays:
CAT/EMMs for DTA are generated on the DAC (DAC 3.11-18), or the CASMR (DAC 4.0
and higher). Settings in this window must match those found in the DAC for DTA to
function on the APEX.
