Enabling/disabling data loss
detection
Enabling (or disabling) data loss detection criteria affects Rx data loss counts
and alarms. Enabling the criteria causes the E1/Datacom Tester to register
data loss when no data transitions have occurred for 63 clock transitions in
synchronous timing modes, or 10 seconds in asynchronous timing modes.
To enable or disable data loss detection
1
If you haven’t already done so, launch the Data Communication applica-
tion (see
“Launching the datacom application” on page 52
).
2
On the Configuration menu, select
Data Loss Enable
.
3
Select
On
to enable data loss detection or
Off
to disable.
You have finished specifying data loss detection.
Specifying the Rx input
The following procedure describes how to specify the Rx input.
To specify the Rx input
1
If you haven’t already done so, launch the Data Communication applica-
tion (see
“Launching the datacom application” on page 52
).
2
On the Configuration menu, select
Rx Input
.
3
Select the r
eceive input termination for the balanced Data interfaces
.
You have finished specifying the Rx input.
Specifying the clock loss threshold
Clock loss threshold refers to the number of milliseconds, without transitions
on the clock signal lead, needed for the E1/Datacom Tester to declare clock
loss. The following procedure describes how to configure the clock loss
threshold.
To specify the clock loss threshold
1
If you haven’t already done so, launch the Data Communication applica-
tion (see
“Launching the datacom application” on page 52
).
2
On the Configuration menu, select
Clock Loss Thres (ms)
.
3
Enter a value for the clock loss threshold.
The default value is 50 ms.
You have finished specifying the clock loss threshold.
Specifying async settings
If you selected Asynchronous as the timing mode, you must specify the char-
acter format for the data.
To specify async settings
1
If you haven’t already done so, launch the Data Communication applica-
tion (see
“Launching the datacom application” on page 52
).
