Software Installation and Verification

Installation Verification

Asampleconfigurationfile/opt/acc/cfg/lapd_4ch_sample.answ file is

provided with the ACC Developer Software Suite product. This sample

file can be used to verify that the HDLC/LAP-D protocol module has been

properly installed and is functional. Note that you need to customize this

file, to reflect the location of the mux card(s) and to reflect the mux ports

to be used. (The lapd_4ch_sample.answ file is shown in Appendix A ,

“Sample Configuration Files,”.)

The steps in the verification process are listed below. It is assumed that

the ACC Developer Software Suite product is installed on the system,

and that there is at least one ACC Multiplexer card installed with

cabling attached.

A loopback cable should be used to connect two of the ports on the

multiplexer. For the configuration file provided, it is assumed that the

first two ports of the mux card are connected with a loopback cab le.

Using the HDLC/LAP-D Protocol Module

The ACC Installation and Configuration Guide contains the general

procedure for configuring the network configuration file, and starting up

the ACC subsystem with the new protocol and new configuration. Refer

to Chapter 4 , “Protocol Specific Configuration,” for HDLC/LAP-D

specific configuration requirements w hen building the network

configuration file.

Verification Procedure

The procedure described involves using the ttgen, zmntr,andzterm

utilities. These utilities are described in the ACC Ut ilities Reference

Guide.

Step 1. Modify the Mux definition statement in the

/opt/acc/cfg/lapd_4ch_sample.answ to reflect the location of the ACC

Mux cards if necessary. (Refer to Chapter 4 , “Protocol Specific

Configuration,” for information on how to modify this statement.)

Step 2. Thesamplefileonlyconfiguresthefirsttwoportsofonemuxcard.If

desired, expand the configuration file to include additional ports.
