Figure 1 Cisco 2600 Series Modular Access Routers
The WAN Interface Cards available for the Cisco 1600,
1700, 2600, and 3600 routers support a variety of serial,
Integrated Services Digital Network Basic Rate Interface
(ISDN BRI), and integrated channel service unit/data
service unit (CSU/DSU) options for primary and backup
WAN connectivity. Network modules available for the
Cisco 2600 and 3600 Series support a broad range of
applications, including multiservice voice/data integration,
analog and ISDN dial access, and serial device
concentration.
The field-installable AIMs supported on all Cisco 2600
Seriesmodels and theCisco3660,enhancethe performance
of the router by off-loading compute-intensive function(s)
onto a dedicated coprocessor while preserving external
interfaceslotsforotherapplications.Various AIMs support
high-performance hardware-assisted data compression or
data encryption (ideal for VPNs). The new AIM-ATM
enables cost-effective ATM over one to four T1/E1
connections, or when used with the high density packet
voice network modules, Voice over ATM (VoATM) can
be provisioned.
Key Benefits
AspartoftheCiscocomprehensiveend-to-endnetworking
solution, the Cisco2600 Seriesallows businesses toextend
a cost-effective, seamless network infrastructure to the
branch office with the following benefits:
• Investment protection—Because the Cisco 2600
Series supports field-upgradable modular
components, customers can easily change network
interfaces without a “forklift upgrade” of the entire
branch office network solution. The AIM slot of the
Cisco 2600 platform further protects investments by
offering the expandability to support advanced
services such as hardware-assisted data compression,
data encryption, or ATM data/voice access.
• Lower cost of ownership—By integrating the
functions of CSU/DSUs, ISDN Network Termination
(NT1) devices, firewall, modems, compression or
encryption devices, and other equipment found in
branch office wiring closets in a single, compact unit,
the Cisco 2600 Series provides a space-saving solution
that can be managed remotely using network
management applications such as CiscoWorks and
CiscoView.
• Multiservice voice/data integration—Cisco offers the
industry’s broadest, scalable multiservice voice/data
integration solution set. The Cisco 2600 Series allows
network managers to reduce long-distance interoffice
calling costs and enables next-generation applications
such as integrated messaging and Web-based call
centers. Using the Voice/Fax modules, the Cisco 2600
may be deployed in both Voice over IP (VoIP) and
Voice over Frame Relay (VoFR) networks. The packet
voice trunk network module supports up to 60
simultaneous voice calls in a Cisco 2600 as well as
supporting routing and other services. When used
with the ATM-AIM, VoATM using AAL2 or AAL5
can be deployed.
• Enterprise/Provider class solution—Meets the
requirements of multiservice enterprises and their
managed service CPE providers with high reliability
features,multiple WANconnections,and theabilityto
migrate from data-only to TDM voice and data to
packetized voice and data infrastructure.
