Cisco 3600 Series
Product Overview
The Cisco 3600 series is a multifunction platform that combines dial access, routing and LAN-to-LAN services and
multiservice integrationofvoice,videoanddatainthesamedevice.TheCisco 3600 series includes the Cisco 3640 and Cisco
3620 access servers/routers. As modular solutions, the Cisco 3640 and Cisco 3620 have the flexibility to meet both current
and future connectivity requirements. The Cisco 3600 series is fully supported by Cisco IOS software, which includes dialup connectivity, LAN-to-LAN routing, data and access security, WAN optimization, and multimedia features.
The Cisco 3640has four network module slots;the Cisco 3620 has twoslots. Each network module slot accepts a variety of
network module interface cards, including LAN and WAN mixed media cards supporting Ethernet, Fast Ethernet, Token
Ring, and a variety of WAN technologies. These cards provide the foundation of LAN and WAN connectivity on a single,
modular, network module. Additional applications are supported with a series of network module cards offering digital
modems, asynchronous and synchronous serial, ISDN PRI, and ISDN BRI interfaces.
The Cisco 3600 shares networkmodules, WAN Interface Cards, and Voice Interface Cards with the Cisco 2600 Series. The
Cisco 3600 shares WAN Interface Cards with the Cisco 1600 and Cisco 1720 Series.

Key Features and Benefits
The Cisco 3640 and Cisco 3620 routers support the following network applications and services:
• Dial-up services
Slot 0
1
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. New integrated digital modems (with support for PRI,
BRI, CT1 and R2) and new integrted analog modems further enhance the dial access flexibility and scalability of the
Cisco 3600.
• ISDN PRI networks
The Cisco 3600 series offers new levelsof costeffectiveISDN PRI concentration. ACisco 3640 configured with aMixed
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 andthree 8-portnetwork modules,a Cisco3640
connects up to 48 B channels. In thisway,one system provides high-density BRIinterface dial-up support and local LAN
and WAN routing connectivity.
• Serial networks
With support for up to 24 synchronous serial interfaces and a mixed media network module, the Cisco 3600 series and
its RISC processor are the perfect complement to the Cisco 2500 and 1600 series. The Cisco 3600’s higher performance
and modular design are appropriate for locations needing support for multiple 56-kbps 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 3640 is ideal for this scenario. It allows migration between interfaces or
simultaneous support of several technologies.
• Power branch applications
The Cisco 3620 allows new levels of connectivity and performance for branch offices with its smaller size, lower slot
density,and lower cost. A combination of onemixed medianetwork moduleplus another network module providesnew
opportunities for branch offices needing more than a fixed-configuration model. The Cisco 3620, for example, provides
multipleLAN access server support for asynchronousand ISDN 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 Cisco3600 series offers midrange LAN-to-LAN connectivity for branch offices
needing a flexible modular platform. This is different from other low- to mid-range Cisco routers. The Cisco 4500 and
Cisco 4700 are the highest-performance access routers and supporta wide array of high-speed LANand WAN interfaces,
including FDDI and ATM. The Cisco 2500 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.
Network Module Options for the Cisco 3600 Series
The Cisco 3640 and Cisco 3620 routers are 4- and 2-slot modular access routers, respectively, whose LAN and WAN
connections are configured by means of interchangeable network modules and WAN interface cards.
The following network modules are available for the Cisco 3640 and Cisco 3620 routers:
• Single-Port High-Speed Serial Interface (HSSI)
• ATM 25 Mbps Network Module
• ATM OC3 155Mbps Network Module
• 6-, 12-, 18-, 24- and 30-digital modem network modules
—LAN with modular WAN (WAN Interface Cards)

Memory, Power Supply, and Cable Options
The Cisco 3600 series uses two types of replaceable or upgradeable memory: DRAM memory and Flash memory.Both types
of memory are implemented with SIMMs. Each router has two Flash SIMMsockets and four DRAM SIMM sockets. In the
standard Flash memory configuration, the first socket contains a 4-MB Flash SIMM, and the second socket is empty. You
can upgrade the Flash memoryto 16 MBon both routers.Each Cisco 3600router ships standardwith 32 MBof DRAM. The
Cisco 3640 is expandable to 128 MB of DRAM. The Cisco 3620 is expandable to 64 MB of DRAM.
The Cisco 3600 series routers use a DRAM memory configuration that is different from other Cisco routers. Unlikethe Cisco
4000series routers, for example, which haveseparate physical locations for processor memory and packet memory,the Cisco
3600 series routers use one pool of DRAM memory. The DRAM is partitioned into processor memory and packet memory
areas. For example, the memory of a 16-MB DRAM configuration is split into 12 MB for processor memory and 4 MB for
the packet memory.
The Cisco 3600 allows you toload new system imagesusing aPCMCIA Flash memorycard. Youcan alsoload images from
a local or remote PC through the console or auxiliary ports using the Xmodem or Ymodem protocols.
