The introduction of the analog modem network modules for the award-winning Cisco 2600 and, 3600, and 3700 platforms expands the already extensive range of network modules currently available for these modular routers. These new cost-effective network modules support basic telephone service connections (RJ-11) and allow up to 8 or 16 concurrent remote analog modem users per network module 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 2600, and 3600, and 3700 customers have best-of-breed scalability, flexibility, and investment protection, all in cost-effective, multifunctional platforms.

• 8 or 16 internal analog modems per network module-Internal modems provide simple setup of your remote access server. There is no separate external power, no mess of cables, and you can have everything in one chassis!
• Support for speeds up to 33.6 kbps-This feature allows users to achieve maximum data transfer rates available today for analog connections, equating to faster file transfers, speedier Web access, and quicker e-mail downloads.
• Ease of configuration-The Cisco 2610 supports the GUI-based configuration tool, the Fast Step utility. This utility is designed to simplify configuration of the Cisco 2610 with analog modems. Using a PC-based graphical interface, the Cisco 2610 can be up and running within 30 minutes from opening the box!
• Centrally managed modem capabilities-These analog modems can be managed via the same Simple Network Management Protocol (SNMP)-based tools used to manage the rest of the network (such as CiscoWorks), providing network managers with one solution at a central management point. Optional enhanced modem management Managed Modem Technology License (MMTL) capabilities allow for the gathering of 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.
• Cisco IOS dial access software-Cisco IOS software provides a broad range of features for the dial-in user, including:
– Autosensing IPX, TCP/IP, AppleTalk Remote Access (ARA), AppleTalk Control Protocol (ATCP)
– Serial Line Internet Protocol (SLIP), PPP, and MP
– Reverse Telnet support for LAN-based dial-out
– Domain Name System (DNS) Domain Name Server support
• 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 users easier access to their home LAN, while maintaining a high degree of security.
• Robust security features-Utilizing TACACS+, Challenge Handshake Protocol/Password Authentication Protocol (CHAP/PAP), Data Encryption Standard (DES) encryption, and the built- in firewall capabilities of the Cisco IOS software allows secure access for remote users to sensitive company data.
