PROGRAMMING PROCEDURES-INSTRUCTIONS/SYSTEM RECORDS<br />
SECTION 100-8<strong>16</strong>-302<br />
MARCH 1993<br />
CENTREX or PBX systems which may vary<br />
the ring pattern to distinguish between inter-<br />
com and incoming calls, etc. If Standard<br />
Ringing is chosen, CO line station ringing<br />
will be a 1 second on, 3 seconds off cycle<br />
regardless of the incoming ring pattern. Some<br />
Central Offices have ringing characteristics<br />
which makes this option undesirable.<br />
l Incoming Call Abandon Timing, LED 05-<br />
The amount of time between incoming CO<br />
line ring signals determines when the sys-<br />
tem will discontinue (abandon) sending<br />
ringing tones to stations. The choice of six or<br />
eight seconds is dependent on the CO ring<br />
pattern. This assignment has no effect if<br />
the CO Repeat Ringing (LED 06) option is<br />
used.<br />
l Dual-tone Multi-frequency (DTMF) Sig-<br />
nal Time, LED 04-DTMF signals sent out<br />
to CO lines can be either 80 or <strong>16</strong>0 millisec-<br />
onds in length. DTMF to QSTU/KSTU/PSTU/<br />
PESU ports (including Voice Mail ports) are<br />
not affected by this assignment. See Pro-<br />
gram 1 O-2 for QSTU/KSTU/PSTU/PESU<br />
DTMF timing. This program also sets the<br />
minimum duration of DTMF tones sent by<br />
pressing a digit on the dialpad of a 2000-<br />
series Digital Telephone-It does not, how-<br />
ever, affect the maximum duration; DTMF<br />
tones sent by2000series Digital Telephones<br />
last as long as a dialpad button is pressed.<br />
l Dial Pulse (DP) Make Ratio, LED 03-Dial<br />
Pulse timing sent out to CO lines can be<br />
changed from the normal 40% make ratio to<br />
33%. This selection only applies to those<br />
CO lines assigned in Program 15 to signal<br />
dialing with DP instead of Dual-tone Multi-<br />
frequency (DTMF).<br />
l CO Line Reseize Guard Time, LED 02-<br />
This LED should be set for 0.45 seconds for<br />
most installations. Set guard time for 1.5<br />
seconds (using Program 1 O-l, LED 02 ON,<br />
and Program 42-O) if CO lines experience<br />
the following situations: no dial tone when a<br />
line is released and reseized immediately;<br />
or, when operating behind CENTREX or<br />
PBX, false hookflash signals are sent to the<br />
Central Office when stations release and<br />
reseize the same CO line immediately.<br />
l Tone FirsWoice First Signaling-Digital<br />
and Electronic Telephone, LED 01-This<br />
2-4<br />
LED sets the signaling method for station<br />
intercom calls to digital and electronic tele-<br />
phones. With Voice First, an intercom call to<br />
an electronic or digital telephone will be<br />
preceded by a one second tone burst, fol-<br />
lowed by voice communication via the<br />
Handsfree Answerback function. For Tone<br />
First, repetitive intercom ring tone is sent in<br />
a one-second on, three-seconds off pattern.<br />
Conversion from one form to the other can<br />
be made by dialing an additional digit of 1<br />
from the calling station.<br />
Program lo-2-System Assignments 2: The<br />
following options are available on a system-<br />
wide basis.<br />
Stations Use External Amplified Confer-<br />
ence, LED 19-This feature should only be<br />
used (LED 19 ON) if an external amplifier(s)<br />
(Program 10-3) is used for two CO line-<br />
station conference calls. This will provide<br />
additional amplification to the station during<br />
the conference call. If an external amplifier is<br />
not switched into two CO line conference<br />
calls in all cases, LED 19 must be OFF if<br />
there is line unbalance which may cause<br />
hum noise on the station talk path during two<br />
CO line conference calls. For <strong>DK</strong>8 and <strong>DK</strong><strong>16</strong>,<br />
it is recommended to test two CO line con-<br />
ference with LED 19 ON; if there is no hum<br />
noise, keep LED 19 ON.<br />
Two CO Line Conference, LED 18-LED<br />
18 should be ON whenever two CO line<br />
(Tandem, DISA) connection is allowed in<br />
Program 15-5 and Program 1 O-l, LEDs 19<br />
and 20. This will increase the volume level<br />
between the two outside parties on a Tan-<br />
dem (two CO line) connection; but, it will not<br />
affect the station volume of any station<br />
conferenced into the Tandem connection.<br />
This option is not associated with external<br />
amplified conference (Program 1 O-3).<br />
“TRNS” Soft Key Immediate Transfer,<br />
LED 17-If this feature is activated and a<br />
transfer is initiated with the “TRNS” Soft Key<br />
on a digital telephone, the call will Ring<br />
Transfer (Camp-on) immediately after the<br />
last digit of the called (busy or idle) station<br />
number is dialed. This feature does not<br />
apply to transfers initiated with the Cnf/Trn<br />
button or the “CONF” Soft Key.
