Responder Mode
Use the Responder Mode screen to specify the type of
responder for the 925VST. When selected, the
925VST will load software specific to the selected
responder function. To exit responder mode, press the
CLR key then reboot the 925VST.
To access the Responder Mode screens, from the Main Menu press the 2 key to display
the Setup menu, then press the 4 key. The default mode is SMOS. For details on set-up
and control using commands (e.g., setting responder mode defaults, answering a call,
stopping a test) via an RS-232 connection, see Remote Control of the 925VST on page 38.
When a 2-wire interface is selected, all responder modes automatically go off-hook in
response to an incoming call. The 925VST then waits 10 seconds for a DTMF command
digit to switch it to a specific responder type. If no command digit is detected within 10
seconds, the 925VST answers as the test line type previously selected during Test setup.
Testing then starts.
When a 4-wire interface is selected, the responders must be started in one of the following
ways.
•
925VST detects DTMF digits 7243.
•
User presses the F1 key to start, and the F2 key to stop.
•
User sends the command “tlstart” via an RS-232 connection. See Remote Control of
the 925VST on page 38 for more information.
SMOS R
ESPONDER
Use DTMF digit 1 to specify SMOS. The 925VST reboots to a state that emulates the
SMOS Responder function (as opposed to an SMOS Director function). In this state, the
925VST waits for an appropriate “seizure” stimulus from the farend SMOS Director
function. In standard 2-wire loop mode, that stimulus is an incoming “ring” signal from
the telephone company central office. This state also supports interactive testing with the
SMOS Test Director test.
In SMOS responder mode, the 925VSWT will stop and restart for the next call when a test
finishes.
To view the current parameters, press the INFO button.
PVIT S
END
Use DTMF digit 3 to specify PVIT. The 925VST reboots to a state in which it emulates a
farend test responder for the test. In this state the 925VST waits for a “seizure” stimulus
from the farend. When it detects a seizure, the 925VST immediately starts transmitting the
