4.2.5.3 Configuring MGCP Attributes
The MGCP (Media Gateway Control Protocol, RFC 3435) configuration specifies how the card will communi-
cate with the network call agent for call signaling. Once the IP provisioning is done for the card’s virtual Ether-
net interface, the MGCP attributes can be provisioned.
Note: Any modification of MGCP parameters requires the card to be disabled.
4.2.5.4 Configuring RTP Attributes
The RTP (Real-Time Protocol, RFC 3550) configuration specifies how the card will exchange bearer packets
with the call agent over the network. Once the IP provisioning is done for the card’s virtual Ethernet interface,
the RTP attributes can be provisioned.
Note: Any modification of RTP parameters requires the card to be disabled.
Note: Users cannot provision country code, it is internally set to North America.
4.2.5.5 POTS24 Port
Configurable attributes for each line interface specify the capabilities of the line that affect analog waveform
transmission and packetization of the analog waveform.
The
SET PORT command with the POTS qualifier is used to modify these attributes.
Note: Modification of these attributes requires the port to be disabled.
A description of the POTS24 port parameters is included in the Telesyn User Guide. Following are the key
parameters for correct configuration:
• MINPACKETIZATION - To support Call Waiting with Caller ID, this attribute should be set to 10 millisec-
onds.
• MAXPACKETIZATION - To support Call Waiting with Caller ID, this attribute should be set to 10 millisec-
onds.
• BUFFERMODE - If a user does not have a modem, then DYNAMIC at 10 msec delay will work. However,
if a modem is ever used, the delay in packets must be deterministic to keep the modems from retraining;
therefore, use STATIC at 10 msec.

4.2.6.1 MGCP Statistics
Statistics supported for the MGCP application running on the POTS24 card are defined in the ATN SNMP
Enterprise MIB. This MIB defines proprietary MIBs for the Telesyn product family. For MGCP, the MIB con-
tains the atnMgcpStatsTable that contains instances of atnMgcpStatsEntry. Supported card specific counters in
atnMgcpStatsEntry include the following:
