12.8 DS1 VF Tasks
The VF Tasks menu performs a variety of talk/listen functions.
DS1 VF Tasks Setup
Note:
Do not attempt to enter VF Tasks if the Frame LED is not green. Green LEDs indicate that the framing found on the
received signal matches the framing selected in the Setup screen. It is impossible to talk, listen, or perform other channelized
functions in the absence of frame synchronization, since channels can be identified only within a framed signal.
The VF Tasks screen features the following options:
Setup:
Tx and Rx T/S:
Input the number of channels (1-24) to test for transmitting and receiving time slots.
Mode:
Talk or send a tone on the transmit signal. Transmit audio data from the external headset into the selected
timeslot.
Code:
Select u-Law or A-Law.
Transmitted Frequency:
Input a frequency to transmit from 50 to 3950 Hz.
Transmitted Level:
Input a frequency to transmit from -60 to 3dBm.
ABCD:
Options are ON-HOOK, OFF-HOOK, WINK, or User (Manually set). Change the signalling bits transmitted with the
associated transmit channel. In SF-D4 framing these will be A/B and ESF framing will place that signal onto the A/B/C/D
position.
Programmable ABCD:
Manual (User) or IDLE, SEIZE.
Results:
Measure signal frequency and level in selected timeslot
