Cisco 3600 Router Series  
Modular, High-Density Access Routers

Cisco 3600 Series Modular, High-Density Access Routers

Product Overview

The Cisco 3600 series is a multifunction platform that combines dial access, routing, and LAN-to-LAN services and multi-service integration of voice, video and data in the same device. The Cisco 3600 series includes the Cisco 3660, the Cisco 3640, and Cisco 3620 multi-service platforms. As modular solutions the Cisco 3660, 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 analog and digital voice capability, ATM access with T1/E1 IMA or OC-3 interfaces, dial-up connectivity, LAN-to-LAN routing, data and access security, WAN optimization, and multimedia features.

The Cisco 3660 has six network module slots; The Cisco 3640 has four network module slots; the Cisco 3620 has two slots. 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. In addition to the 6 network module slots the Cisco 3660 has 2 internal Advanced Integration Module (AIM) slots for applications such as hardware accelerated compression and the chassis incorporates 1 or optionally 2 integrated 10/100 (Ethernet/Fast Ethernet) ports.

The Cisco 3600 series shares network modules, WAN Interface Cards, and Voice Interface Cards with the Cisco 2600 series. The Cisco 3600 series shares WAN Interface Cards with the Cisco 1600 and Cisco 1700 series.

Options for Cisco 3600 Series

Key Features and Benefits

The Cisco 3660, Cisco 3640, and Cisco 3620 routers support the following network applications and services:

Network Module Options for the Cisco 3600 Series

The Cisco 3660, Cisco 3640, and Cisco 3620 routers are 6-, 4- and 2-slot multiservice access routers, respectively, whose LAN and WAN connections are configured by means of interchangeable network modules and WAN interface cards. The Cisco 3660 also incorporates 1 or optionally 2 integrated 10/100 (Ethernet/Fast Ethernet) ports.The following network modules are available for the Cisco 3660, Cisco 3640, and Cisco 3620 routers:

In addition the Cisco 3660 supports 2 internal AIM slots. The Data Compression Advanced Integration Module (AIM) for the Cisco 3660 Series delivers a cost-effective option for reducing recurring wide-area network (WAN) costs and maximizing the benefit of the advanced bandwidth management features of Cisco IOS. The Data Compression AIM takes advantage of either of the two available Cisco 3660 internal AIM slots, ensuring that external slots remain available for components such as integrated analog voice/fax, digital voice/fax, ATM, channel service unit/digital service units (CSU/DSUs), analog and digital modems.

The figure below shows how a vacant chassis slot on the Cisco 3640 accepts a mixed media network module, which in turn accepts a WAN interface card.

Memory, Power Supply, and Cable Options

The Cisco 3620/40 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 SIMM sockets and four DRAM SIMM sockets. In the standard Flash memory configuration, the first socket contains a 8 MB Flash SIMM, and the second socket is empty. You can upgrade the Flash memory to 32 MB on both routers. Each Cisco 3600 router ships standard with 32 MB of DRAM. The Cisco 3640 is expandable to 128 MB of DRAM. The Cisco 3620 is expandable to 64 MB of DRAM.

The Cisco 3660 series uses two types of replaceable or upgradeable memory: SDRAM memory and Flash memory. Flash memory is implemented with SIMMs whereas SDRAM memory uses DIMMS. The 3660 has two Flash SIMM sockets and two SDRAM DIMM sockets. In the standard Flash memory configuration, the first socket contains a 8 MB Flash SIMM, and the second socket is empty. You can upgrade the Flash memory to 64 MB on a 3660 router. Each Cisco 3600 router ships standard with 32 MB of SDRAM and is upgradable to 256 MB of SDRAM.

The Cisco 3600 series routers use a DRAM memory configuration that is different from other Cisco routers. Unlike the Cisco 4000 series routers, for example, which have separate 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 to load new system images using a PCMCIA Flash memory card. You can also load images from a local or remote PC through the console or auxiliary ports using the Xmodem or Ymodem protocols.
