Configuring the Access Gateways

This section describes the commands that are used to configure the following Catalyst 6500 series access gateway modules:

Analog station gateway—24-port FXS analog interface module

Digital trunk gateway—8-port T1/E1 PSTN interface module

Configuring a Port Voice Interface

If DHCP is enabled for a port, the port obtains all other configuration information from the TFTP server. When disabling DHCP on a port, you must specify some mandatory parameters as follows:

If you do not specify the DNS parameters, the software uses the system DNS configuration on the supervisor engine to configure the port.

8-port T1/E1 PSTN interface module only: You cannot specify more than one port at a time because a unique IP address must be set for each port.

To configure a port voice interface for the DHCP, TFTP, and DNS servers, perform this task in privileged mode:
