Cisco IOS Software Configuration for the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

Prerequisites for the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

Prerequisites for the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

The Cisco 12000 Series Router must have at least one clock and scheduler card (CSC) installed that provides a one-quarter bandwidth to support the requirements of the 1-port channelized OC-12/STM-4 (DS3) line card.

Information About the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

The 1-port channelized OC-12/STM-4 (DS3) line card provides 12 channels of DS3 multiplexed over a single 622-Mbps OC-12 port. The 1-port channelized OC-12/STM-4 (DS3) line card interfaces through an Add Drop Multiplexer (ADM) with other DS3 line cards at DS3 line rates in a configuration that usually consists of a Cisco 7200 Series Router and a Cisco 7500 Series Router configured with the packet-over-E3/T3 (POET) port adapter, or a third-party T3 data service unit (DSU) such as Digital Link, Larscom, or Kentrox.

The 1-port channelized OC-12/STM-4 (DS3) line card interfaces with the Cisco 12000 Series Router switch fabric and provides one OC-12 duplex SC single-mode intermediate-reach Synchronous Optical Network (SONET) connection.

How to Configure the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

The following sections provide information for configuring and verifying the configuration.

•Configuring the OC-12 Controller, page 2

•Configuring the DS3 Serial Interface, page 4

•Cisco Remote Connection Management, page 5

•Using show Commands to Check System Status, page 8

•Using Loopback Commands, page 12

•Configuring DS3 Port BER Testing, page 13

Configuring the OC-12 Controller

Use the configure command to configure the new OC-12 controller. A Cisco 12000 Series Router identifies a controller by slot/port. The current OC-12 controller-configurable parameter settings are displayed as part of the show controller oc12 number/0 command, as in the following example:

Router# show controller oc12 1/0

OC12_CH_DS31/0

The current state of the controller is up

Current configurable parameter settings:

Clock source is LINE, Payload scrambling is ON

Loopback is NONE
