detector is intended to sense when the
calling device has gone on-hook and the
processor can then terminate the ringing
sequence.
port device then functions as normal.
However, with a priority port pro-
grammed, typically port 1, if the priority
device goes off-hook while another port
is conversing, the processor will cut off
that device and hang up the line. As soon
as the central office connected to the LINE
IN detects the on-hook condition, the pri-
ority device will draw loop current from
the central office and then receive a dial-
tone.
Some other features are if power is lost,
K2 will de-energize and short the LINE
IN to port 1 connection allowing at least
one outgoing connection to occur. A FAX
tone detection circuit listens when a FAX
machine normally sends its type 3 tones
and, if programmed, may automatically
route the call to the assigned port. A dial-
tone detector, U4, checks the line for dial-
tone after a port has started ringing. This

Ring On Time *50PXXX# XXX = 010
Sets the ring on cadence in hundredths of seconds. P = 1-8, XXX = 001-999 (1 second)
Ring Off Time *51PXXX# XXX = 030
Sets the ring off cadence in hundredths of seconds. P = 1-8, XXX = 001-999 (3 seconds)
Number of Rings *52PXX# XX = 16
Sets the number of rings before disconnecting. P = 1-8, XX = 01-99 (16 rings)
Tone During Ring On Time *53PX# X = 1
Sets the tone that the caller will hear during the Ring On Time. P = 1-8, X = 0-5
