Cisco 1600 Series — Modular Desktop Access Routers

Product Overview

The Cisco 1600 series have become the proven choice for data access for small branch ofﬁces and small businesses because

they offer a range of features speciﬁcally designed for such applications:

• Modular design for wide-area network (WAN) choice and ﬂexibility

• Advanced security, including optional integrated ﬁrewall, encryption, and virtual private network (VPN) software

• End-to-end quality of service (QoS) and multimedia support

• Integrated data service unit/channel service unit (DSU/CSU) with up to T1 speed and integrated Network Termination

(NT1)

• Low cost of ownership through WAN bandwidth optimization

• Ease of use, deployment, and management

The Cisco 1700 series routers build on the success of the Cisco 1600 routers, delivering multiservice capabilities, as well as

greater modularity, security, and integration to small ofﬁces.

Cisco 1600 Series Modular Routers

Cisco 1600 series routers connect small ofﬁces with Ethernet LANs to WANs through Integrated Services Digital Network

(ISDN), asynchronous serial, and synchronous serial connections.

The ﬁve basic conﬁgurations of the Cisco 1600 product family offer the following ports:

• Cisco 1601 R — one Ethernet, one serial, one WAN interface

• Cisco 1602 R — one Ethernet, one serial with integrated 56-kbps DSU/CSU, one WAN interface card slot

• Cisco 1603 R — one Ethernet, one ISDN Basic Rate Interface (BRI) (S/T interface), one WAN interface card slot

• Cisco 1604 R — one Ethernet, one ISDN BRI with integrated NT1 (U interface), one S-bus port for ISDN phones, one

WAN interface card slot

• Cisco 1605 R — two Ethernet slots, one WAN interface card slot

The serial WAN port on the Cisco 1601 R router supports asynchronous serial connections of up to 115.2 kbps and

synchronous serial connections — such as Frame Relay, leased lines, Switched 56, Switched Multimegabit Data Service

(SMDS), and X.25 — of up to 2.048 Mbps. The Cisco 1602 R router integrates a 56-kbps four-wire DSU/CSU, and it

supports the same synchronous serial connections as the Cisco 1601 R router (except SMDS). The ISDN BRI port on the

Cisco 1603 R router has an S/T interface, while the Cisco 1604 R includes an integrated NT1 with a U interface. The Cisco

1605 R router provides a 10BaseT and an AUI port on the ﬁrst Ethernet interface and a 10BaseT port on the second Ethernet

interface.

Run From RAM Architecture

The 1601 R-1605 R routers have a “run-from-RAM” architecture; the “R” sufﬁx designates run from “RAM”. The Cisco

IOS software image is stored in Flash memory (in compressed form), but is loaded into RAM before being executed by the

router.

The Run-from-RAM models offer the following beneﬁts:

1. Greater Performance — The Cisco 1600 R models deliver greater performance for memory-intensive applications such as

encryption and compression.

2. Easier Upgradability — The Cisco 1600 R routers permit software upgrades over any interface while the router is running

3. Lower Cost — Because the Cisco 1600 R models store the software in compressed form in Flash memory, less ﬂash

memory is required to run advanced feature sets (such as Cisco 1600 series IOS IP Plus). The new Cisco 1600 R routers

(1601 R, 1602 R, 1603 R, and 1604 R) are essentially the same as the original models (1601-1604), but they are “run-from-
