Cisco 3700 Series
Modular Access Routers
The Cisco 3700 Series is a new line of modular routers that enable flexible and
scalable deployment of new applications in an integrated branch office access
platform. The Cisco 3700 Series is ideal for sites and solutions requiring the highest
levels of integration at the edge for branch office IP Telephony, voice gateway, and
integrated flexible routing with low-density switching solutions. The Cisco 3700
Series provides a consolidated service infrastructure and high service density in a
compact form factor that enables the incremental integration of branch applications.
High Service Density
This series introduces a new, wider interface
form factor—the High Density Services Module
(HDSM). With four network module (NM) slots,
the Cisco 3745 can accept two HDSMs by
removing the center guides between each pair
of adjacent NM slots. With two NM slots, the
Cisco 3725 can accept an HDSM in one while
still leaving the other free. Each model also
offers three WAN Interface Card (WIC) slots and
two Advanced Integration Module (AIM) slots.
Integrated Flexible Routing
and Low-Density Switching
When configured with the new 16- or 36-port
EtherSwitch Module, the Cisco 3700 Series
offers a single, integrated platform that
combines flexible routing and low-density
switching. This offers high-speed connections
between individual desktops, servers, and other
network resources in a single unit for Layer 2,
and allows WAN connection at Layer 3 through
the router. An optional external power chassis
provides power to IP phones and Aironet 802.11
Base Stations.
Integration/Manageability
Provides a single-platform solution for branch
office IP telephony and voice gateway services,
lowering costs of ownership, simplifying
management, and allowing flexible, incremental
migration and integration.
Versatility/Investment Protection
Thousands of field-upgradable customized
solutions ensure easy migration to future
network requirements. More than 70 WAN
interface cards (WICs), and Network Modules
are shared with the Cisco 1600, 1700, 2600,
and 3600 series products. Modules can be
interchanged between small, midsize, and
regional branch offices. The advanced
integration module (AIM) slot offers
expandability for integration of advanced
services, such as hardware-assisted data
compression, encryption, Voice and ATM
hardware-assisted data compression,
and encryption.
