Introduction

The 1-port serial WAN interface card (WIC-1T) provides serial connections to remote sites or legacy serial network devices such as Synchronous Data Link Control (SDLC) concentrators, alarm systems, and packet over SONET (POS) devices.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

This document is not restricted to specific software and hardware versions.

Product Number

WIC-1T

One Port Serial WAN Interface Card

Features

One serial port.
Uses the Cisco 60-pin "5-in-1" connector. This connector is DB-60 on one end and can be V.35, RS-232, RS-449, X.21 or EIE-530 on the other end depending on your needs
Uses the same cabling as Cisco 2500 and Cisco 7000 serial ports.
Does not support hot swap, however no hardware damage will occur if it is swapped while the power is on.
Each serial card has one LED, labeled CONN for each port, which lights when the serial port is connected. When the port is in data terminal equipment (DTE) mode, the CONN LED indicates that Data Set Ready (DSR), Data Carrier Detect (DCD), and Clear To Send (CTS) have been detected. When the port is in data communications equipment (DCE) mode, it indicates that Data Terminal Ready (DTR) and Request To Send (RTS) have been detected.

Note: All parameters mentioned in this table for the Cisco 1700 series routers are also applicable to Cisco 1800 series routers.

Configuration

This section provides a sample configuration for the WIC-1T interface card.

Note: There are no framing, clocking, or linecode parameters or commands being used here. The WIC-1T interface card does not have an integrated CSU/DSU. You need to use an external CSU/DSU.

Configure the serial interface just as you would any other serial interface. For example,

maui-soho-01(config)#interface Serial 0
maui-soho-01(config-if)#ip add 10.0.0.1 255.255.255.0
maui-soho-01(config-if)#encapsulation ppp
maui-soho-01(config-if)#no shutdown

If your platform supports async, then use the physical-layer async command for async mode. Such an application is useful to connect an external modem to the router. Refer to the document 2 Port Async/Sync WAN Interface Card (WIC-2A/S) for an example.
