The telephone system then detects current flowing from its battery. The
current flow energizes relays in the telephone system, which connects bi-
directional audio lines through Tip and Ring to the PeopleAlert with
Telephone.
Once connected, the PeopleAlert 2601 with Telephone prompts the caller to
enter a pager number with a tone. The caller must enter this number via a
true DTMF tone (touch tone) telephone. The DTMF tones must be at least 50
mSec in duration with at least a 50-mSec pause between digits. Numbers
entered via Rotary dial, or some Digital phone systems are not recognized by
the PeopleAlert with Telephone.
Termination of the call can be accomplished in three different ways:
1) The calling party hangs up their telephone before the PeopleAlert 2601
with Telephone times out. This terminates the call at the telephone end, but
not at the encoder’s end. The disconnect created by the caller hanging up its
telephone never makes it through the connection between the telephone
system and the PeopleAlert with Telephone. To overcome this loss of a
disconnect signal the encoder uses an ‘inactivity timer’ which will time out and
terminate the call, in the encoder, after a loss of audio on Tip and Ring for
approximately four seconds.
1. 2) The PeopleAlert 2601 with Telephone times out before the calling
party hangs up the telephone; this terminates the call at the encoder’s
end.
3) The calling party enters the correct string of digits described in the section
‘Paging a Single Pager Using the Telephone Interconnect’. When the last
(#) pound key is pressed, the 2601 will disconnect and terminate the call.
