Chapter 4 Configuring the PA-VXA, PA-VXB, and PA-VXC
Configuring the Interface
Performing a Basic Configuration
This section describes guidelines for performing a basic configuration: enabling the PA-VXA, PA-VXB,
or PA-VXC port adapter, specifying the card type and controller, and entering various controller
subcommands. After configuring the PA-VXA, PA-VXB, or PA-VXC port adapter in a Cisco 7200 series
router, Cisco 7200 VXR router, Cisco 7301 router, Cisco 7401ASR router, or Cisco 7500 series router,
see the
“Configuring Voice over IP” section on page 4-6
for information on configuring your router for
VoIP.
Specifying Card Type is Required
Because the port adapter can be configured for E1 or T1 connectivity, you must specify the card type as
E1 or T1, as described in the following procedure. There is no default card type. The port adapter is not
functional until the card type is set. Information about the port adapter is not indicated in the output of
any show commands unless the card type has been set to E1 or T1.
Before using the configure command, you must enter the privileged level of the EXEC command
interpreter with the enable command. The system prompts you for a password if one has been set.
Use the following procedure to configure the PA-VXA, PA-VXB, or PA-VXC port adapters. Press the
Return key after each configuration step, unless otherwise noted.
Step 1
Confirm that the system recognizes the PA-VXA, PA-VXB, or PA-VXC port adapter by entering the
show running-config command:
Router# show running-config
Step 2
Use the configure terminal command to enter configuration mode and specify that the console terminal
is the source of the configuration subcommands:
Router# configure terminal
Step 3
Specify whether the card is to be used as T1 or E1 by using the card type command in configuration
mode. The example below sets the card in slot 1 of a Cisco 7200 series router to T1:
Router(config)# card type t1 1
The example below sets the card in slot 1 of a Cisco 7200 series router to E1:
Router(config)# card type e1 1
The example below sets the card in port adapter slot 0 on a VIP in interface processor slot 1 of a Cisco
7500 series router to T1:
Router(config)# card type t1 1 0
The example below sets the card in port adapter slot 0 on a VIP in interface processor slot 1 of a Cisco
7500 series router to E1:
Router(config)# card type e1 1 0
Note
To change the card type of the PA-VXA, PA-VXB, or PA-VXC after the card type command
has been entered, you must remove the card from the router, save the running configuration
to startup configuration, and reboot the router. When the router has finished rebooting,
reinsert the card and repeat
