This chapter provides information on the Cisco 1600 series of modular routers for small offices. The information is organized into the following sections:
The Cisco 1600 series of access routers delivers the next-generation set of features and benefits for small-office Internet and intranet access: WAN flexibility, end-to-end security, end-to-end quality of service, ease of use, deployment, and management. The Cisco 1600 series routers connect small offices with Ethernet LANs to the public Internet and to a company's internal intranet or corporate LAN through several WAN connections such as ISDN, asynchronous serial, and synchronous serial. The Cisco 1600 series routers include the following models: the Cisco 1601, Cisco 1602, Cisco 1603, Cisco 1604, and Cisco 1605-R.
All Cisco 1600 series models include one Ethernet port, one built-in WAN port, and one WAN interface card expansion slot for additional connectivity and flexibility. The Cisco 1601 (see Figure 114) includes a built-in serial WAN port; the Cisco 1602 (see Figure 115) has an onboard 56-kbps, four-wire Channel Service Unit/Data Service Unit (CSU/DSU); the Cisco 1603 (see Figure 116) has an ISDN BRI S/T port; the Cisco 1604 (see Figure 118) includes an ISDN BRI U interface with a built-in NT1 device; and the Cisco 1605-6 (see Figure 118) includes an ISDN BRI U interface with a built-in NT1 device.
The WAN-card slot in the Cisco 1600 series allows you to change or add WAN interface cards as your WAN requirements grow or change over time. With this feature, the Cisco 1600 series routers offer you more flexibility and investment protection than any other products in their class.
The Cisco 1600 series routers help protect your investment in an environment of rapid change in WAN requirements and telecommunications. If your business requirements or choices from the service provider change, simply add or change (upgrade) the WAN interface card to use a new WAN technology or service. Most WAN interface cards are interchangeable with any Cisco 1600 and Cisco 3600 series routers. The ISDN WAN interface cards are not supported by the Cisco 1603 and Cisco 1604 routers.The Cisco 1605-R router has an integrated WAN interface.
The Cisco 1600 series routers offer the most complete set of internetworking software features for a small-office Internet or intranet access device. Cisco IOS software and its suite of protocol and applications support differentiates the Cisco 1600 from the competition in the following areas:
The Cisco 1600 series routers are designed to be plug-and-play devices--installation can be performed by nontechnical personnel while ongoing administration can be performed through a centralized site. Preconfigured software can be loaded into a PC Flash memory card at a central site and then sent to remote sites, where users can simply perform plug-and-play installation. The Cisco 1600 also comes with a variety of easy, user-friendly installation features such as Web browser-based ClickStart for initial configuration. AutoInstall allows you to download software upgrades and configuration modifications from a central site over the Frame Relay or leased line WAN. Additionally, the Cisco 1600 allows for centralized administration/management using SNMP, Telnet, or through the console port. These features combine to give the lowest total-cost-of-ownership (the sum of deployment costs, administrative costs, and WAN costs).
Table 60 lists the features common to all Cisco 1600 series routers.

The Cisco 1600 series routers support Cisco IOS Releases 11.2 and 11.1.
The following types of feature sets are offered:
The Cisco IOS feature set tables use the following conventions to identify features:
Software feature packs consist of CD-ROMs that contain Cisco IOS software feature set images and a Windows 95 application, which loads the images onto a router.
Software feature packs are available for most of the Cisco IOS Release 11.2 feature set images. Table 64 lists the product numbers for feature sets and feature packs available in Cisco IOS Release 11.2. Software feature packs are available only for Cisco IOS Release 11.2 and later releases
For more information about software feature packs, see the "Cisco IOS Feature Packs" section in the "Cisco IOS Software" chapter earlier in the catalog.
