Setting Up Lines

A circuit line is the physical line that carries frame relay, data, voice, or ATM traffic between customer equipment and an IPX or IGX node. Each piece of equipment in the illustration above is attached to the node through a circuit line. After a card has been "upped" with the upcd command, a circuit line on that card can be "upped" and configured.

This chapter:

Describes input circuit line formats
Summarizes circuit line card combinations
Explains how to set up lines
Describes each command

The following table shows the permissible card combinations for IPX and IGX circuit lines.

Setting Up a Circuit Line

Frame relay, data, and voice connections require an active circuit line. Use the commands in the following steps to establish a circuit line and its parameters. The card must be active (upcd) before these commands can execute.

Step 1 Use upcln to activate a circuit line in a slot that contains the appropriate circuit line card set.

Step 2 Use cnfcln to configure the circuit line.

The upcln and cnfcln commands establish the general parameters for the circuit line. They do not establish specific frame relay, data, or voice parameters. Refer to the appropriate chapter for details of setting up a particular service on a circuit line/ line. For example, the Data Connections chapter describes specific commands for data connections, and the Frame Relay Connections chapter describes specific commands for frame relay connections.

Other Circuit Line Commands

The following describes related commands.

dncln—downs a circuit line. A downed line is inactive, so no drive signals or statistics are generated. All connections on a circuit line must be removed (delcon or delcongrp) before it can be downed with dncln.
dspclncnf—displays the configuration of a specified circuit line.
dspclns—displays the circuit line configuration and alarm status for the node.
prtclns—prints the circuit line configuration and circuit line alarm status for the node.

Next Command:

prtclns

Prints the current circuit line configuration for the IPX or IGX node. This command uses the same syntax, and prints the same information as is displayed using the dspclns command. See the dspclns command for syntax and output information.

Example Description

prtclns

Prints circuit line for the node.

upcln

Activates a circuit line on an IPX or IGX. A circuit line consists of a cable for transmitting data and the interface circuitry for the line. The cable can be a coaxial wire, fiber optic, or a twisted pair. See Table 6-2 for information on card combinations.

The upcln command makes the line visible and usable to the network. You must execute upcln at both ends of the line. Executing upcln at only one end of the circuit line eventually causes an alarm. Once both ends of the line are active, you can configure the line's signal characteristics for the data you intend for the circuit line. See cnfcln for information on defining these characteristics.
