Mobile Programming of Auto-dial Numbers
If enabled by parameter 55, mobile users can install or modify telephone numbers in the auto-dial
memory. Following are instructions regarding how this is accomplished.
1. With the PL1877A in the idle state, dial *0* from the mobile DTMF keypad. The PL1877A
responds by transmitting three mid-frequency beeps. The PL1877A is now waiting for you to enter a
valid auto-dial location number (1–25) followed by a *.
N OTE : Auto-dial locations 10–25 are only available for use and modification if the selective
signaling option is present. If you enter an invalid auto- dial location number, the PL1877A
generates 6 disconnect beeps and exit the auto-dial programming mode.
2. Upon receipt of the * following the location number, the PL1877A opens the auto-dial location and
waits for you to enter a phone number. Enter the desired phone number.
You can program the PL1877A to pause between digits of a telephone number. This is useful when
you are dialing out of a PABX and must wait for the PSTN (external) dial tone before continuing
dialing. To place a pause in an auto-dial telephone number, enter a DTMF * at the desired point.
For example, if you want the PL1877A to dial 9 (pause) 948–1490, enter the following into the auto-
dial location: 9*9481490.
If the PL1877A is programmed for pulse dialing, you can cause the PL1877A to dial several auto-dial
digits in pulse then pause and switch to dialing the remaining digits in DTMF. This is called a
“revert” since the PL1877A reverts from pulse dialing to DTMF dialing. To place a revert in an
auto-dial telephone number, enter a DTMF # at the desired point. For example, if you want the
PL1877A to dial 9 (revert) 948–1490 (where the 9 is dialed in pulse and 948–1490 is dialed in
DTMF), enter the following into the auto-dial location: 9#9481490.
N OTES :
•
Only one revert can be placed in an auto-dial telephone number. If you place more than one
revert in a number, all reverts subsequent to the first will only cause the PL1877A to pause in
dialing.
•
Two adjacent pauses or reverts cannot be entered into an auto-dial telephone number. This is
because **, ##, *#, and #* are commands that cause the PL1877A to perform certain functions
(see the paragraphs below). Also, a pause or revert cannot be the last digit of an auto-dial
telephone number. If you wish to cause a long pause, simply modify the pause duration via
parameter 128. The PL1877A automatically pauses when a revert character is encountered, so it
is not necessary to enter adjacent pauses and reverts.
•
You can cause the PL1877A to revert from pulse to DTMF dialing when manually dialing
telephone numbers (that is, when not using the auto-dial feature). To accomplish this, program
the PL1877A for pulse dialing (parameter 31 = 1) and DTMF regeneration subsequent to receipt
of a * (parameter 36 = 1; parameter 37 = 1). Then, when dialing a telephone number, enter a *
where you wish the revert to occur. For example, if you wanted to dial 9 (revert) 948 - 1490, you
would dial 9*. Then, after pausing the required amount of time, you would dial 948 - 1490.
3. While you are entering the auto-dial telephone number, pressing ** causes the PL1877A to key the
transmitter and repeat the input digits received so far. This is useful in determining that you have not
made any mistakes while entering the number.
