Alarm type
The Alarm type field allows the user to select type of alarm to be generated.
LOS
: Loss of Signal.
AIS
: Alarm Indication Signal. The transmitter will send all ones.
LOF
: Transmit loss of FRM synchronizing signal.
LOM
: Transmit loss of multiframe synchronization in TS16 (loss of MFAS multiframe synchronizing signal (ITU-T
G.704, sub clause 5.1.3.2)).
RDI
: Remote Defect Indication (ITU-T G.706). The test set transmits “1” in every third bit of the timeslot in zero
frame which does not contain frame synchronization signal. The FAS DISTANT alarm signal could be transmitted
only in PCM-30 and PCM-31 systems.
RMA
: Remote Multiframe Alarm (ITU-T G.732). The analyzer transmits “1” in every sixth bit of the timeslot in zero
frame TS16. The MFAS DISTANT alarm signal could be transmitted only in PCM-30 systems.
LSS
: Test Pattern synchronization loss.
ARTF
: Transmission of unstructured alternating 1s and 0s.
Time
The Time field allows the user to select a duration of the alarm generating process:
0.1
: 0.1 second
0.5
: 0.5 second
1
: 1 second
2
: 2 seconds
5
: 5 seconds
Cont
.: Continuous generation.
Start/stop alarms generating
The Alarm field allows the user to control the process of alarms generating.
Pulse shape
This menu provides the ability to display and analyze the pulses produced by E1 equipment. The pulse height and
overall shape are displayed against the ITU-T pulse mask conformance template.
Operation
1.
Switch the analyzer on.
2.
Connect the measuring cable #1 to the instrument.
3.
In the “Line Interface” menu select the “Terminal” or “Monitor” operation mode.
4.
Connect measuring cable to the tested equipment.
Pulse shape monitoring
Test set will automatically display the single pulse against the ITU-T G.703 pulse shape mask.
