Cisco NM-8AM-V2 and NM-16AM-V2 Analog
Modem Network Modules with V.92
The Cisco NM-8AM-V2 and NM-16AM-V2 Analog Modem Network Modules with V.92 serve as
integrated analog modem network modules (NMs) for the modular access routers (MARS) family of
routers. These network modules terminate either 8 or 16 analog modem connections through POTS
interfaces.
For information on new features and Cisco IOS commands supported by software for the Cisco
NM-8AM-V2 and NM-16AM-V2 network modules, see the “Additional References” section on page 8.

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.

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
