Introduction

This document provides an overview of the WIC-1DSU-56K4 interface card, and provides a sample configuration to use this interface card on Cisco 1600, 1700, 2600, 3600 and 3700 series router platforms.

Prerequisites

Requirements

Features

The four-wire 56k Channel Service Unit/Data Service Unit (CSU/DSU) implements switched 56k and Digital Data Storage (DDS or leased line) operation, and also:

  • Supports DDS loop rates 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 kbps.

  • Supports Switched 56 operation at 56 kbps (AT&T Pub. 41458, Sprint TS-0046)

  • Has receiver sensitivity of -45db at all loop rates.

  • Has these diagnostic functions:

    • Self Test Function (at power on and user initiated) Network line, and data terminal equipment (DTE) loopbacks.

    • User initiated DTE, line, and remote V.54 loopbacks.

Supported Platforms

This table lists the various platforms that are supported:

Platform Cisco IOS Software Support
1600 CiscoIOS® Software Release 11.2(9)P, 11.3(3)T, and all 12.x releases.
1700 All Cisco IOS Software Releases.
2600, 2600XM All Cisco IOS Software Releases.
3620, 3640 Cisco IOS Software Release 11.2(4)XA, 11.2(5)P, all 11.3, 11.3T, and all 12.x releases.
3631 All Cisco IOS Software Releases.

Sample Configuration

Here is a sample configuration suitable for a WIC-1DSU-56K4 interface card.

Note: There are no framing or linecode commands. This is because the 56k card is not a T1, and does not relate to timeslots. There are 24 timeslots in a T1:

Note: 24 x 64 DS0s=1.544m

Note: This card is strictly 56k, and timeslots are not relevant. Here is the configuration:

Configuration
interface serial 0/0
service-module 56k clock rate 56
service-module 56k clock source internal
ip address 10.1.1.1 255.255.255.0
encapsulation ppp
no shut
