LED 03: Dial Pulse (DP) Make Ratio
Dial Pulse timing sent out to Exchange lines can be changed from the normal 40% make ratio
to 33%. This selection only applies to those Exchange lines assigned in Program 15 to signal
dialling with dial pulse instead of Dual-tone Multi-frequency (DTMF).
LED 02: Line Reseize Guard Time
Should be set for 0.45 seconds for most installations. Set guard time for 1.5 seconds (using
Program 10-1, LED 02 ON, and Program 42-0), if Exchange lines experience the following
situations: no dial tone when a line is released and reseized immediately; or, when operating
behind PBX, false hookflash signals are sent to the local exchange when stations release and
reseize the same line immediately.
LED 01: Tone First/Voice First Signalling-Electronic and Digital
Telephone
With Voice First, a Directory Number call to an electronic or digital telephone will be
preceded by a one-second burst of tone, followed by voice communication via the Handsfree
Answerback function. For Tone First, repetitive Directory Number ring tone is sent in a one-
second on, three-seconds off pattern. Conversion from one signalling mode to the other can
be made by dialling an additional digit of 1 from the calling station.
