BERT Config
(Where BERT is the acronym for Bit Error Rate Test) Use the drop-down lists to:
• Configure the Tx or Rx BERT State as On or Off.
• Configure the Tx or Rx BERT Pattern as 2^23-1 (2 23 -1) or 2047.
• Set Error Insertion as either Off or 10E-3.
Select the desired BERT settings. Click [Submit] to save the settings and execute the test.
BERT Monitor
This section displays the ongoing BERT. Click [Restart] to restart the BERT Monitor. Otherwise,
click [Update] to refresh a test already in progress.
Once the Tx BERT is executed, the entire outbound carrier transmits a BERT pattern.
All IP communications are halted during this test.
Note also that the Rx BERT State for the CDM-840 must be enabled for a CDM-800
Gateway Router to properly receive and monitor the BERT pattern.
Redundancy
• Current Redundancy State (read-only) – Status is listed as On Line or Off Line.
• Offline Unit Status (read-only) – This indicates the status of the offline unit.
If the unit is not connected to a redundancy switch, the status is listed as No_1F1.
Otherwise, its status is listed as On Line or Off Line.
If the unit is part of a 1:1 or 1:N redundant pair of CDM-840s, and this unit is currently On Line,
click [Force Redundancy Switch] to cause the unit to switch to standby.
Console Configuration
Use the drop-down list to select the desired communications protocol for the rear panel
‘CONSOLE’ port. Click [Submit] to save. The available selections are:
o RS232-8N1-38400 o RS485-8N1-9600 o RS485-8N1-19200
