Analog Modem Network Modules

Cisco is pleased to introduce the latest members of its ever-expanding range of network modules for the 3600 Series and 2600 Series Modular Routers. Two new internal analog modem network modules are now available, an 8 analog modem network module, and a 16 analog modem network module. These new cost-effective network modules support basic telephone service connections (RJ-11) and allow up to 16 remote analog modem users to connect to a Cisco 2600 or 3620, and up to 48 users to connect to a Cisco 3640. Combined with the differentiated services delivered through Cisco IOS software, Cisco 3600 and 2600 customers have best-of-breed scalability, flexibility, and investment protection, all in cost-effective, multifunctional platforms. A Cisco 2600 or 3620 combined with an 8- or 16-port analog modem network module provides the ideal mid-density RAS. A variety of LAN topologies, including Ethernet and Token Ring are supported. Cisco IOS software provides for a wide range of protocols, such as TCP/IP, IPX, NetBEUI, and AppleTalk. Cisco IOS software also provides for a wide range of dial-related software features, such as MP and firewall support.

Key Features and Benefits

8 or 16 internal V.34 analog modems per network module
Color-coded RJ-11 jacks for direct connection to telco
Support for speeds up to 33.6 kbps
Ease of configuration with award winning GUI-based configuration tool, Fast Step.
Centrally managed modem capabilities SNMP based tools used to manage the rest of the network (such as CiscoWorks
Optional enhanced modem management (Managed Modem Technology License [MMTL]) capabilities
Support for a broad range of dial-in features with Cisco IOS dial access software
Modems are software upgradable to support possible future changes

These features enable a wide variety of dial-in clients to utilize the applications and facilities of the branch office network.

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 Protocol/Password Authentication Protocol (CHAP/PAP), 56-bit Data Encryption Standard (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.

Specifications

Software

Network Management:

Fast Step: Graphical user interface (GUI) configuration tool designed to simplify configuration of the Cisco 2610 with analog modems.
CiscoWorks: Allows centralized management of multiple Cisco 2600 and 3600 routers.
In-band and out-of-band management via TCP/IP and SNMP, including Management Information Base II (MIB II) and other extensions, over TCP/IP
TCP/IP addresses can be assigned via Dynamic Host Configuration Protocol (DHCP), per user, via an internal address pool, or selected remotely
Maintains a detailed activity log for accounting, billing, and troubleshooting
Advanced management using the (optional) MMTL
Ability to download image and configuration across routers

Security:

User name, password, and dial-back security
Multilevel administration password support
CHAP and PAP support
Centralized authentication via authentication, authorization, and accounting (AAA)
IP device and network filtering
AppleTalk zone and device filtering

Modem Management:

The Cisco 2600 and Cisco 3600 series ship with general network management capabilities. A managed modem application is available as an option (Part Number: MMTL-3600/2600-8= or MMTL-3600/2600-16=). The Modem Management Technology License (MMTL) is licensed in steps of 8 modems; a part number is available for each. The MMTL, if utilized, must be licensed for all modems in the chassis, a maximum of 16 per 2600 chassis. MMTL is only supported on a Cisco IOS "Plus" image.

The optional Modem Management Technology License support capabilities include:

Provides for modem statistics, real-time call-in-progress, monitoring modem activity log, modem hard/soft busy out, and the ability to accomplish modem firmware upgrades. All these features result in reduced downtime, lower support costs, and lower operating costs.
Sends AT commands (while the modem is connected) for additional testing and debugging capabilities.

Note Country Availability/Homologation: The analog modem network module is being submitted for approval worldwide, but due to specific in-country approval processes, approval dates vary. For the latest availability status, please check Cisco Connection Online at http://www.cisco.com.
