Cisco 1721 And 1760 Module Interfaces - Cisco 2651 User Manual

Cisco IOS features such as tunneling, data encryption, and termination of Remote Access WANs via
IPSec, Layer 2 Forwarding (L2F) and Layer 2 Tunneling Protocols (L2TP) make the Cisco 1700 an ideal
platform for building virtual private networks or outsourced dial solutions. Cisco 1700`s RISC-based
processor provides the power needed for the dynamic requirements of the remote branch office.

Cisco 1721 and 1760 Module Interfaces

The interfaces for the router are located on the rear panel of the Cisco 1721 and the front panel of the
Cisco 1760 as shown in

The Cisco 1721 and 1760 routers feature console and auxiliary ports, single fixed LAN interfaces, two
Cisco WAN interface card (WIC) slots on the 1721, and two WIC slots and two Voice interface card
(VIC) slots on the 1760. WAN interface cards support a variety of serial, ISDN BRI, and integrated
CSU/DSU options for primary and backup WAN connectivity. All Cisco 1700 series routers include an
auxiliary port supporting 115Kbps Dial-On-Demand Routing, ideal for back-up WAN connectivity.
A WIC is inserted into one of the WIC slots, which are located on the back panel of the 1721 and the
front panel of the 1760. WICs interface directly with the processor, and cannot perform cryptographic
functions; they only serve as a data input and data output physical interface.
The physical interfaces include a power plug for the power supply and a power switch. The router has
one Fast Ethernet (10/100 RJ-45) connector for data transfers in and out. The module also has two other
RJ-45 connectors on the back panel for a console terminal for local system access and an auxiliary port
