Foundry AR-Series AR1202 and AR1204 Installation Guide

Network Tests

If the system is not working correctly after verifying that the cabling is correct between the Foundry router and the external network equipment, run these basic tests to isolate the problem to the LAN port, WAN link, or serial interface ports.

Ping Test

The Ping test checks connectivity between the Foundry system and another host system on the LAN. If an “unknown host” error occurs after initiating this test, the destination host is either unreachable or unstable, or it does not exist. If a 100 percent packet loss error occurs, the LAN is either down or unstable.

•ping

Use this command to check connectivity with another system.

Other Tests

To isolate problems with a faulty WAN link, perform line or payload loopbacks at either end of the link and perform a BERT test. These functions isolate a problem to either the AR1202 and AR1204, far-end equipment, interconnect cabling at either end, or the link between the two systems.

Loopback Test

To perform line and payload loopbacks at either end, use the appropriate derivative (T1/E1) of the following commands.

The following loopback command is available.

•test t1 loopback

BERT Test

This command is used to initiate a bit error rate test. The following BERT test command is available to test specific links.

•test t1 bert

The pattern parameter may have any of the following values:

 

Table B.1: BERT Test Patterns

 

 

Pattern

Description

 

 

2^11

Pseudorandom pattern with no more than 10 consecutive zeros and no

 

more than 11 consecutive ones.

 

 

2^15

Pseudorandom pattern with no more than 14 consecutive zeros and no

 

more than 15 consecutive ones. Use this pattern for testing at data rates

 

above 19.2 kbps (G.703-standard test).

 

 

2^23

Pseudorandom signal with no more than 22 consecutive zeros and no

 

more than 23 consecutive ones. This pattern provides the highest stress of

 

all BERT patterns.

 

 

QRW

Quasi-random waveform pattern (default). This pattern simulates live data.
