Send and Monitor Pattern Tests

he pattern tests enable a FrameSaver unit to either send or monitor a known bit pattern. These tests generate industry-standard bit patterns that can be used to determine whether information is being correctly transmitted across a circuit.

he following test patterns are available:

QRSS

511

All-zeros

2047

All-ones

2E15-1 (215-1)

1-in-8

2E20-1 (220-1)

3-in-24

User-defined 2-byte test pattern (a0a0)

63

 

A Send Pattern test cannot be started when the following tests are running:

Any Loopback on the same interface.

TSend Pattern Test on any port assigned to this network interface.

Send V.54 or FT1 Loopback, or Data Channel Loopback on any synchronous data port (Port Use set to Synchronous) and assigned to this network interface.

Procedure

To send and monitor a Pattern Test:

1. Follow this menu selection sequence:

Main Menu Test[Network Physical Tests/DSX-1 Physical Tests]

2.Select the desired pattern in the Send or Monitor field. If sending/monitoring a user-defined pattern, enter the the desired 2-byte hexadecimal value in the field next to Send or Monitor.

When sending a pattern, the InjectERR function key appears. Use InjectERR if you want to inject a bit error in the transmitted bit pattern.

3.To send a pattern, highlight the Send command to send a pattern and press Enter.

To monitor the test, highlight the Start command and press Enter.

The length of time that the test has been running is shown in the Result column. An error count is also displayed. When monitoring a pattern, the ResetMon function key appears. ResetMon resets the error count to zero.

4.To stop the test, press Enter to send the Stop command. Start reappears and the status of the test changes back to Inactive.
