Cisco 3600 Series

Cisco 3600 Series

This chapter provides information on the Cisco 3600 series access servers/routers. It is organized into the following sections:

Product Overview

The Cisco 3600 series is a multifunction platform that combines dial access, routing, and LAN-to-LAN services and multiservice integration of voice, video, and data in the same device. The Cisco 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 dial-up connectivity, LAN-to-LAN routing, data and access security, WAN optimization, and multimedia features.

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.

Figure 61 and Figure 62 show the Cisco 3600 series router rear views.

The Cisco 3640 and Cisco 3620 routers support the following network applications and 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. New digital modes modules further enhance the dial access flexibility and scalability of the Cisco 3600.
The Cisco 3600 series offers new levels of cost effective ISDN PRI concentration. A Cisco 3640 configured with a LAN network module and three 2-port ISDN PRI network modules supports up to 138 (T1) or 180 (E1) B channels. This is a powerful and cost effective way to aggregate many branch offices and telecommuters onto one corporate network.
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 3640 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.
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.
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.
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 one mixed media network module plus another network module provides new opportunities for branch offices needing more than a fixed-configuration model. The Cisco 3620, for example, provides multiple LAN access server support for asynchronous and 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.
Consistent with its other capabilities, the Cisco 3600 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 support a wide array of high-speed LAN and 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.

4- and 8-Port ISDN BRI Network Modules

Four versions of BRI network modules are available. Each 4- and 8-port module has the option of an S/T interface or an onboard NT1 for each port. (See Figure 76 through Figure 79.) These modules are installed in any slot in the Cisco 3600 series routers. Local SRAM is used for buffer descriptors and input queues. The 4-port module is not field upgradeable to the 8-port module.

With all eight BRI ports running continuous data (144 kbps each) and 50-byte packets, the maximum performance possible is 5760 pps and an aggregate full-duplex data rate of 2.3 Mbps.

The ISDN BRI network modules support the following features:

1-Port and 4-Port Ethernet Network Modules

There are two different Ethernet network modules available for the Cisco 3600 series routers: 1-port and 4-port. The 1-port Ethernet network module has one Ethernet attachment unit interface (AUI) DB-15 connector and one 10BaseT RJ-45 connector. Only one of these two connections can be active at a time. (See Figure 84.)

The 4-port Ethernet network module supports up to four Ethernet connections. Ethernet port 0 uses either the AUI (DB-15) connector on the right side of the module or the 10BaseT (RJ-45) connector next to it, but only one of these two connections can be active at a time. Ethernet ports 1, 2, and 3 use 10BaseT connectors; these ports do not provide an AUI connector. (See Figure 85.)

The 1-port and 4-port Ethernet network modules require Cisco IOS Release 11.2(4)XA, 11.2(5)P, or later.


Figure 84: 1-Port Ethernet Network Module




Figure 85: 4-Port Ethernet Network Module



1-Port Fast Ethernet Network Module

The 1-port Fast Ethernet network module has one RJ-45 port. (See Figure 86.) This port connects to two-pair Category 5 UTP cabling following the 100BaseTX physical layer protocol.


Figure 86: 1-Port Fast Ethernet Network Module



4-Port Serial Network Module

The 4-port serial network module has four DB-60 ports and provides a data rate of 8 Mbps on port 0, 4 Mbps each on port 0 and port 2, or 2 Mbps on all four ports simultaneously. (See Figure 87.)


Figure 87: 4-Port Serial Network Module



Compression Network Module

The compression network module compresses and decompresses data passing through interfaces on other network modules or WAN interface cards in the router. (See Figure 88.) The following interfaces are supported:

Hardware compression is supported only over PPP links and only by means of the Stacker compression algorithm.

Memory, Power Supply, and Cable Options

This section describes the memory, power supply, and cable options for the Cisco 3600 series routers.

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 SIMM sockets 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 memory to 32 MB on both routers. Each Cisco 3600 router ships standard with 16 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 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.

Note For guidelines on how to order the proper amount of memory to support different network module configurations, refer to product bulletin 544, 3600 Series Memory Options and Configuration Guide. This document is accessible from Cisco Connection On-line (CCO). The URL is http://www.cisco.com/warp/public/728/3600/index.html.

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.

Hardware Product Numbers

The Cisco 3600 series routers offer the hardware, network modules, WAN interface cards, memory options, power supplies, and cables listed in Table 49. If a product number ends with an equal sign (=), the item can be ordered only as a spare. If a product number does not end with an equal sign, the item can be ordered as a spare or as a configurable part of a system order. If a base system product number ends with -CH, the item is available either through the Cisco authorized reseller channel, or through your local Cisco sales office. Other hardware options can also be ordered through the Cisco authorized reseller channel.
