Front Panel Operation
1.6.2 START Key: This key transmits the "Start" signal according to the "Start Signal"
parameter that has been defined by the "DIALING: START SIGNAL" EMULATE parameter.
•
For "dial tone", another press of the key will remove it.
•
For "delay" start signal (similar to "wink"), another press before it's programmed
end time (START TIME: DLY: /ENDms) will terminate it.
•
For "wink", each press will send a "wink" of the programmed duration (WINK:
/DURms).
•
For "immediate" dial, it has no function for a Te/Line that is set for analog (loop)
operation.
1.6.3 RING Key: This key sends ringing to alert the terminal equipment that a call is coming
from the AM8a. Ringing will be applied according to the "RINGING:" parameters given
in the EMULATE Setup. Pressing the RING key again will remove the ringing signal.
CAUTION: Placing an excessive (>5 REN) Load across Tip Ring during Ring
application may cause the AM8a to reset. Ringing will not be
generated if any of the following conditions exist:
1.
Low battery indication on display.
2.
Loop is seized ( i.e. Off Hook).
3.
If > 14mA ring trip current is detected.
4.
An excessive ringer load exists for several minutes.
Unit is emulating a TE/LINE in analog loop mode.
5.
1.6.4 REV Key: This key controls battery polarity for the line under test when emulating a
Switch. Each press changes the polarity on the line. This key is equivalent to the
SEIZE key when Emulating TE/LINE equipment.
1.6.5 SEND TONE ([SHIFT][RING]) key: This is a secondary function of the RING key. Press
[SHIFT] then [RING] and the AM8a will send a single tone at the Level and Frequency
programmed in the EMULATE "SEND TONE:" setup parameters.
