Cisco 1600 Series

The Cisco 1600 series has 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 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 connections: Cisco 1601 R—one Ethernet, one serial, one WAN interface card slot 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 ports, 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.
