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.

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.

Information About Cisco NM-8AM-V2 and NM-16AM-V2 Network Modules
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:
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
