22 Installation and Operation
TIF-2000A
Dialing a Call
To
dial a call on the TIF-2000A using a KP-32
, do the following:
1.
Press the
listen key
for the line you wish to dial on.
This allows you to hear dial tone, and your DTMF dialing tones
.
2.
Enter dial mode by entering
PHONE-PGM-T
.
PHONE is the 4 button on the keypad. PGM is on the keypad, and T is the talk key which is programmed to talk to the
TIF-2000A you are dialing on. Leave the talk key in the latched position as you dial the number.
3.
Dial the
number
.
As you enter each digit, it appears in the alpha display above the key you are dialing on. If the listen key is latched, you
hear each DTMF tone as it is generated.
4.
When you have completed dialing, momentarily turn
off
the talk key to exit dial mode.
The alpha numeric display reverts to normal, and you may use the key and keypad in the normal manner.
NOTE:
Digits 0-9 generate the DTMF digits 0-9. PGM generates the #, and CLR generate * (# and * are displayed for
these keys). It is necessary to press CLR twice if you wish to generate an *, as a single CLR is used to trigger the
speed dial and redial features.
To
dial a call on the TIF-2000A using a KP-12 or KP-32
, do the following:
1.
Tap the
phone key
to begin your call.
This places the keypanel in dial mode: the CALL indicator turns on, and the MAN DIAL (manual dial) displays in the call
waiting window. You should also hear the dial tone.
NOTE:
You can hang up the phone line at this time by simply tapping the phone key again.
2.
Tap
SEL
(select) to select MAN DIAL.
The twelve intercom keys can now be used to dial a telephone number. Each key corresponds to the number printed next to
it on the front of the panel. If the keypanel has alphanumeric displays, the key numbers are displayed above each key.
3.
Begin
dialing
the number by tapping the appropriate keys.
After you dial the first digit, END DIAL appears in the call waiting window.
4.
When you have completed the dialing, tap
SEL
to select END DIAL.
This returns the keypanel to normal operating mode. If the called party answers, proceed with your conversation.
Hanging Up
The TIF-2000A detects if the call at the far end has hung up under most circumstances. It detects the hang up by either loop
interrupt, battery reversal, or the presence of a dial tone or busy signal. Some telephone systems do not provide any of the above, so
it is necessary to force a hang up. In addition, if the call was placed to an auto-answer device, it is necessary to force a hang up
when the call is complete.
Enter PHONE-CLR-T, where PHONE is the 4 on the keypad, CLR is the CLR button, and T is the talk key which is programmed
to talk to the TIF-2000A which you want to hang up. This disconnects the line for which you struck the talk key.
NOTE:
If talk is in the on position, you must turn off the key, then momentarily turn it on again to indicate which line you
wish to disconnect. If the line is in dialing mode, then you must first exit dialing mode by turning off the key, then use
PHONE-CLR-T to hang up.
