The UDPPORT parameter in the AMO SIPCO applies similarly for DMC slave
connections where NCUI2+/NCUI4 is the DMC endpoint. The following ports
are automatically used.
Maximum port number for a board with 120 B channels:
With DMC:
up to 100 ports for the master connections + up to 100 ports for the associated
DMC connections
=> 200 ports for the RTP and 200 ports for the RTCP stream
Without DMC:
up to 120 ports for the master connections
=> 120 ports for the RTP and 120 ports for the RTCP stream
An even port (such as 29000) is always selected for the RTP stream. The next
odd port is selected for the appropriate RTCP port, i.e. RTCP port= RTP port
+1.
IMPORTANT: The ports in use cannot be modified with the exception of
ports for "UDP-Payload".
The following are a few examples to clarify the traffic restrictions applied to certain
ports.
20.2.1 Payload
Depending on the board in use (HG 3500 or HG 3575), ports used are taken from
a certain port range defined by the parameter UDPPORT (AMO SIPCO). The port
range for RTP/RTCP is defined by the following interval: [UDPPORT ..
UDPPORT + 247].
Port 4007 is used for a path test in the case of poor payload quality. See
4.8.1, "When is Payload Survivability Used?"
Architecture (IPDA) and Access Point Emergency (APE)" - keyword "UDP-PINA".
