Overview

Two new analog modem network modules, the Cisco NM-8AM-V2 and NM-16AM-V2 network modules, support basic telephone service connections on Cisco 2600XM series routers, Cisco 3600 series, and Cisco 3700 series. These network modules allow the following:

???Standard telephone connections on RJ-11 connectors

???Up to 16 remote analog modem users to connect to a Cisco 2600XM series

???Up to 32 remote analog modem users to connect to a Cisco 3725

???Up to 64 remote analog modem users to connect to a Cisco 3745

???Up to 96 remote analog modem users to connect to a Cisco 3660

Combined with the differentiated services delivered through Cisco IOS software, users of

Cisco 2600XM series, Cisco 3600 series, and Cisco 3700 series routers have best-of-breed scalability, flexibility, and investment protection, all in cost-effective, multifunctional platforms.

???Virtual private network (VPN) support???This feature allows for cost-effective connections for a geographically dispersed user base. It can reduce access cost support and allow remote users straightforward access to their office LAN through a local Internet service provider (ISP), while maintaining a high degree of end-to-end security.

???Robust security features???Utilizing TACACS+, Challenge Handshake Authentication Protocol/Password Authentication Protocol (CHAP/PAP), Triple Data Encryption Standard (3-DES) encryption, and the built-in firewall capabilities of Cisco IOS software allows secure access for a wide variety of remote users to sensitive company data.

Network Management

???CiscoWorks???Allows centralized management of multiple Cisco 2600XM, Cisco 3600, and Cisco 3700 routers.

???In-band management via TCP/IP and SNMP, including MIB II and other extensions, over TCP/IP.

???TCP/IP addresses can be assigned via DHCP, per user, or via an internal address pool, or they can be selected remotely.

???Maintains a detailed activity log for accounting, billing, and troubleshooting.

???Ability to download image and configuration across routers.

Security

???Username, password, and dial-back security

???Multilevel administration password support

???CHAP and PAP support

???Centralized authentication via AAA

???IP device and network filtering

???AppleTalk zone and device filtering

Modem Management

Chat Script

The Cisco NM-8AM-V2 and NM-16AM-V2 network modules support chat script as well as modem cap entries like other Cisco modem modules. There is no need to put a factory reset parameter in the chat script because this will interfere with the modem settings configured internally by the Cisco NM-xAM-V2 firmware. The same applies to the modem cap entry. If a factory reset parameter is included, the parameter may interfere with how the connection speed is collected and the modem may be unreliable in any reports on the speed.

When using the AT&F reset parameter in a chat-script with Cisco NM-8AM-V2 and NM-16AM-V2 network modules, the reset parameter should be used in conjunction with the connect string setting. For example:

AT&F\\v1s0=1

This setting gives a factory reset, a long connect string, and answers after one ring. For more information, refer to the documentation at:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fdial_c/fnsprt2/dafmchat.ht m

When using the &f0 reset parameter in the modem cap entry with Cisco NM-8AM-V2 and NM-16AM-V2 network modules, the reset parameter should be used in conjunction with the connect string setting. For example:

modemcap entry NM-V2-CONEXANT-MAXSPEED-TEST2:MSC=&f0\V1S0=1

To customize the modem firmware behavior according to the country of deployment, use the modem country smart_acf command in global configuration mode. To set the default value, use the no form of this command.

modem country smart_acf country-name

no modem country smart_acf country-name

Usage Guidelines Use this command to set the modem for use in a specific country. When a country name is specified, the firmware customizes the modem for use in the country where it is deployed. The following table includes valid values for the country-name argument and the country or countries associated with each argument value.
