Dial-up services
The Cisco 3600 is a mid-range dial-up platform that fits between Cisco’s AccessPath and AS5300 products at the high
end and the Cisco 2500 series access servers at the low end. Mixed-mode and high density ISDN and asynchronous
configurations offer substantial flexibility in dial-up applications. Integrated digital modems (with support for PRI, BRI,
CT1 and R2) and new integrated analog modems further enhance the dial access flexibility and scalability of the
Cisco 3600.
ISDN PRI networks
The Cisco 3600 series offers high levels of cost effective ISDN PRI concentration. A Cisco 3640A configured with a
Mixed Media LAN/ISDN PRI network module and three 2-port ISDN PRI network modules supports up to 186 (T1) or
240 (E1) B channels. This is a powerful and cost effective way to aggregate many branch offices and telecommuters onto
one corporate network.
ISDN BRI networks
For areas of the world where ISDN BRI services are more widely available or cost effective, the Cisco 3600 series
supports many BRI interfaces. Configured with a LAN network module and three 8-port network modules, a Cisco
3640A connects up to 48 B channels. In this way, one system provides high-density BRI interface dial-up support and
local LAN and WAN routing connectivity.
Serial networks
With support for up to 96 synchronous serial interfaces on the Cisco 3660, the Cisco 3600 series and its RISC processor
are the perfect complement to the Cisco 2600, 2500, 1700, and 1600 series. The Cisco 3600’s higher performance and
modular design are appropriate for locations needing support for multiple T1/E1 links or the ability to change
configurations in the future.
Mixed WAN services
Many corporate environments require support for a mixture of ISDN PRI, ISDN BRI, asynchronous serial, and
synchronous serial connections. The Cisco 3600 series is ideal for this scenario. It allows migration between interfaces
or simultaneous support of several technologies.
Multiservice access solutions and applications
The three Cisco 3600 models allow new levels of connectivity and performance for branch offices with their scalable size,
slot density, and cost. Combinations of network modules provide new opportunities for branch offices needing more than
a fixed-configuration solution. The Cisco 3620, for example, provides multiple LAN access server support for
asynchronous, ISDN, analog modem and digital modem environments, which complements the Cisco 2500 series access
servers. Alternatively, a Cisco 3620 adds multiple LAN capabilities to branch bank environments needing to assimilate
legacy serial devices, connecting them all to a high-speed Frame Relay network.
LAN-to-LAN services
Consistent with its other capabilities, the Cisco 3600 series offers midrange LAN-to-LAN connectivity for branch offices
needing a flexible modular platform. The Cisco 2600 series, with a multitude of fixed configurations, offers cost effective
branch office solutions including integrated routers and hubs, single and dual LAN routers, and multiple serial routers.
Ethernet Switching
The Cisco 3640A and Cisco 3660 offer integrated Ethernet switching on a network module. Integrated Ethernet switching
combines the benefits of local LAN access with branch office routing. Ethernet switching is available with 16 ports (Cisco
3640A and Cisco 3660) or 36 ports (Cisco 3600 only) of 10/100 Ethernet with optional in-line phone power and optional
gigabit Ethernet uplink.
Content Networking
Content Acceleration and Delivery enhance user productivity while optimizing WAN bandwidth. The Content Engine
Network Modules combine the advanced content acceleration features of the Content Engine 500 Series with the 2600,
3600, and 3700 Series into one easy to manage content networking solution.
