Cisco Catalyst 4000 Access Gateway Module Installation and Configuration Note
OL-3008-01
Chapter 5 Configuring the Voice Interfaces
MGCP Configuration
Step 3 Enable MGCP for the port by entering the following commands:
Gateway(config)# dial-peer voice 1 pots
Gateway(config-dial-peer)# application mgcpapp port <portnumber>:<ds0group>
Replace portnumber with the port number on the voice gateway you are configuring and ds0group with
the DS0 group number.
Example 5-2 illustrates a typical configuration of T1-CAS E&M emulation with MGCP:
Example 5-2 T-1 CAS E&M Emulation for MGCP
Gateway(config-controller)# ds0-group 0 timeslots 1 type e&m-wink-start
Gateway(config)# dial-peer voice 1 pots
Gateway(config-dial-peer)# application MGCPAPP
Gateway(config-dial-peer)# port 1/0:0
Configuring T1/E1 (ISDN-PRI) Ports
To configure an E1/T1 multiflex interface with ISDN-PRI signalling, use the Cisco IOS command line
to perform the procedures in this section.
Configuring T1 Interfaces
To configure a new T1 interface or to change the configuration of an existing interface, perform the
following procedure:
Step 1 Identify the port number and enter line-specific information provided by your local carrier.
a. Choose the T1/PRI interface to configure:
Gateway(config)# controller t1 1/0
This example configures a T1 interface in slot 1 and unit 0.
b. Specify which end of the circuit provides clocking:
Gateway(config-controller)# clock source line
Set the clock source to use internal clocking only for testing the network. Set one end of the T1 line to
internal.
c. Specify the framing type:
Gateway(config-controller)# framing esf
d. Specify the line code format:
Gateway(config-controller)# linecode b8zs
Step 2 Configure parameters for the voice interface.
a. Specify the PRI group and time slots to be mapped:
Gateway(config-controller)# pri-group timeslots 1-24 service mgcp
For multiflex trunk interfaces, you can configure only channel 0.
b. Configure each PRI group as a virtual serial interface:
