Chapter 5 Configuring the Voice Interfaces
T1/E1 Configuration (H.323)
Gateway 2 Configuration
This is the sample configuration for gateway 2:
dial-peer voice 1 pots
port 1/0/0
destination-pattern 2000
T1/E1 Configuration (H.323)
This section describes how to configure an ISDN PRI interface or T1/E1 multiflex trunk interface on
your AGM. This section contains the following subsections:
Configuring T1 Interfaces, page 5-22
T1/PRI Configuration Example, page 5-23
Configuring E1 Interfaces, page 5-23
E1/PRI Configuration Example, page 5-24
Configuring T1 Interfaces
Use the following procedure to configure a new T1 interface or to change the configuration of an existing
interface. After completing these steps, configure the route pattern and dial plan and save your
configuration, as described in “H.323 Gateway Configuration” section on page 5-12.
Step 1 Identify the port number and enter line-specific information provided by your local carrier.
a. Select 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
The clock source should be set to use internal clocking only for testing the network or if the full T1
line is used as the channel group. Only one end of the T1 line should be set 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
For multiflex trunk interfaces, only channel 0 can be configured.
b. Configure each pri-group as a virtual serial interface.
gateway(config-controller)# interface serial 1/0:15
