Detail Programming Setup Values Continued
Ring Hit Counter: (Defaults to 3)
Command to set: 5n Where "n" is the number of rings counted before auto answering.
When the unit is called ring hit cycles are counted.
After the first ring hit, the unit will automatically absorb Caller ID if the Modem is
installed. The caller ID is retained in the audit log.
This ring hit counter serves many different functions as follows:
If the Ring Hit Count value is set to zero "0":
After optional Caller ID is absorbed the unit will answer with a melody.
It will then wait for 12 seconds during which touch tones are tested for.
If a two digit touch tone number is received then a test is made for a match with this
units preprogrammed extension codes. If it matches the Touch Tone Extension Code then the
unit will remain in the answer mode and all other units sharing this line that don't match
the extension code will dismiss themselves. In this way several products may share the
line and the caller may specify which units to dismiss and which one is to remain for
programming or other purposes. All line sharing units must be programmed to respond with
this same method and each must have a unique two digit extension code assigned.
If the two digit touch tone code is a match with the units Modem Extension Code then that
unit will switch to Modem Answer Mode while all others dismiss themselves. This technique
allows multiple units with Modems to share a common line. The trick to this is to program
the PC dialer program to dial the phone number that several Modem units may share. The
number to dial must include about 8 seconds of embedded pause time before dialing the
remaining two digits of the phone number. All units sharing the line will answer at the
same time and wait for two additional touch tone digits. This PC dialer uses embedded
pauses after the full primary phone number, then the two final phone number digits. The
dialer is unaware the Modems have all answered already and completes dialing the phone
number as directed. Thus the PC dialer can be specific to which unit it connects to.
The dialer number would look like this: 5551212,,,,,,99 (comas are treated as pauses)
This method is also useful if one wishes to have the dual ability to call a unit that has
a Modem but needs the touch tone mode, rather than Modem mode, so touch tone commands can
be issued to latch a gate open, etc.
If the Ring Hit Count value is set to "1,2,3,4,5,6 or 7":
Any of these values simply cause the unit to count that number of full rings before
automatically answering the incoming call. If a Modem is installed, it will activate
within 6 seconds upon answering, before which normal touch tone functions can be employed.
If the Ring Hit Count value is set to eight "8":
This mode employs audio ring to the units speaker and allows the incoming call to be
answered manually by pushing the call button or lifting the handset. The call must be
manually answered before the 8th ring. Otherwise the unit will divert to auto answer in
the extension code mode as described above for setting the ring count to zero.
If the Ring Hit Count value is set to nine "9":
This mode employs audio ring to the units speaker and allows the incoming call to be
answered manually by pushing the call button or lifting the handset. The call must be
manually answered before the 9th ring. Otherwise the unit will divert to auto answer in
the normal mode as described above for setting the ring count to 1,2,3,4,5,6 or 7.
Manual answer modes are most often employed on the one button dialers. The unit is usually
mounted near the security guard at the gate portal and calls can be placed to the security
guard from inside the building to give special instructions about lunch breaks or traffic
to be expected. The unit retains it's ability to be remotely programmed by simply ringing
it long enough to auto answer for programming or other purposes.
Note: In manual answer modes Relay 3 is engaged during ring hits for lighting a ring alert
lamp, just in case the guard can't hear the ringing sound from the speaker.
