OVERVIEW  
Digital Modem Network Modules  
for the Cisco 3600 Platform  
Introduction  
1. Note: These digital modem network modules must operate in conjunction with a  
TI/EI/PRI/BRI network module. For details on supported PRI network modules, see  
the “Technical Specifications” section.  
The Cisco 3600 Series is a family of modular, multifunction access  
routers for medium and large-sized offices and smaller Internet  
Service Providers. With over 70 modular interface options, the Cisco  
3600 family provides solutions for voice/data integration, virtual  
private networks (VPNs) dial access, and multiprotocol data routing.  
Using Cisco’s Voice/Fax network modules, the Cisco 3600 Series  
allows customers to consolidate voice, fax, and data traffic on a  
single network infrastructure. The high-performance, modular  
architecture of the Cisco 3600 Series protects customers’ investment  
in network technology and integrates the functions of several devices  
into a single, manageable solution.  
Now, with this announcement of the new digital modem  
network modules, the Cisco 3600 expands its role as a multifunction,  
branch/enterprise orientated platform that, supports voice over data,  
dial access and LAN-to-LAN or routing in one modular platform,  
making it an ideal solution for the “power branch” environment.

Utilizing TACACS+, Challenge Handshake Authentication  
Protocol/Password Authentication Protocol (CHAP/PAP), 56-bit  
Data Encryption Standard (DES) encryption and the built-in firewall  
capabilities of the Cisco 3600 allows secure access for remote users  
to sensitive company data.  
Digital Modem Applications  
Historically, branch office connectivity has been synonymous with  
connecting the local LAN to a regional or central site. With the rapid  
growth in mobile computing and telecommuting, more and more  
branch offices need to add user-to-LAN capabilities.  
Using ISDN PRI, ISDN BRI or Fast Ethernet/ISDN PRI, and  
digital modem network modules, the Cisco 3600 provides the ideal  
functionality for the branch and enterprise offices.  
Life Cycle-Focused Support Solutions  
Cisco’s comprehensive support portfolio delivers solutions  
that enhance the network throughout its life cycle. From design and  
installation, to preventive and scheduled maintenance, to performance  
optimization, Cisco’s solutions promote network reliability,  
efficiency, and flexibility. Designed to function as an integral product  
component, these programs deliver seamless support. Together, they  
proactively help organizations sharpen their competitive edge.  
Through access to the Cisco Connection Online (CCO) Web site,  
customers can both use and market expanded functionality and new  
features as soon as they become available. Moreover, access to Cisco’s  
technical expertise is available around the clock and around the globe.  
This virtual team of the world’s top networking engineers is equipped  
to address every need from troubleshooting to network design  
and planning.  
Figure 1 illustrates a typical application for the ISDN PRI and  
digital modem network modules.  
For basic telephone users, both 33.6K and 56K modem calls  
can be terminated through a PRI/BRI connection into a digital  
modem network module, including mobile workers and people  
working from hotel rooms. For teleworkers with access to Basic  
Rate Interface (BRI), the same phone number could be used to  
connect to the same Cisco 3600, achieving 64 kbps non-compressed,  
or with multilink PPP, 128 kbps.  
Multiple backhaul options are available to link back to  
a corporate network, at speeds up to 8 Mbps. Additionally, a slower  
speed (T1 or Frame Relay, for example) connection could link the  
branch to the World Wide Web.

with products from the Cisco 2509-12 series, through the  
Cisco 3600 series, to the Cisco 5X00 series, making up a broad  
range of dial solutions targeted at different market segments,  
including small branch, enterprise, ISPs, telcos, and carriers.  
Other dial-focused network modules of the Cisco 3600  
include 16 and 32 port high-density async network modules,  
ISDN network modules, eight and 16 port analog modem  
network. These modules address the high-density async market  
(up to 192 async ports) for external modems banks and terminal
