Configuration Example; Configuring The Digital Modem Network Module For The Cisco 3640 Router - Cisco 2611XM Software Configuration Manual

Configuring the Digital Modem Network Module for the Cisco 3640 Router

To configure compression over PPP, perform the following tasks in interface configuration mode:
Step 1
Step 2
Step 3

Configuration Example

The following example enables hardware compression and PPP encapsulation on serial interface 3/1.
Although the Serial interface in slot 3/1 is configured with the compress stac command, the actual data
compression takes place in the hardware compression card inserted in a different slot.
Router(config)# interface serial 3/1
Router(config-if)# encapsulate ppp
Router(config-if)# compress stac
Router(config-if)# exit
Router(config)#
Configuring the Digital Modem Network Module for the
Cisco 3640 Router
The Digital Modem Network Module for the Cisco 3640 is a high-density digital network module
containing 6, 12, 18, 24, or 30 digital (MICA) modems. These modems provide a direct digital
connection to an Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) channel. This
digital modem network module allows the access server to support a mix of both digital data calls
(ISDN) and analog modem calls over a single digital network interface.
Depending on the modem license you purchase with your Cisco 3640, the modems on the Digital Modem
Network Module are either manageable or not manageable by Cisco IOS software commands. If the
license you purchase includes this modem management capability, you can use the modem management
commands to gather call and performance statistics at any time, even if there is an active call on the
modem.
The Digital Modem Network Module for the Cisco 3640 provides the following benefits:
