System & Station
Program 35 – Station Class of Service
3-102 Strata DK Programming 5/00
LED 17: Continuous DTMF Tones Off
2000-series digital telephones can send DTMF tones for as long as station users press their buttons
(80 msec. minimum). This feature can be disabled (LED 17 On). If it is disabled, DTMF tones sent
by these telephones will be either 80 or 160 milliseconds depending on the selection made with
Program 10-1, LED 04 and Program 10-2, LED 06.
Note PDKU1 does not support continuous DTMF tones on 2000-series digital telephones.
LED 16: No Call Forward/No Answer on Handsfree Answerback
When enabled (LED 16 On), a Handsfree Answerback call to an idle station in the Call Forward
No-Answer or Call Forward-Busy/No Answer mode is not forwarded. If the system is
Programmed for Voice first (Program 10-1 and 10-2, LED 01 Off), Voice Announce calls do not
Call Forward No-Answer; however, calls will call forward busy. This prevents the call from being
forwarded 8-60 seconds after the called party has been talking in the Handsfree Answerback
mode.
Outside calls and busy internal calls to the station continue to forward with this feature set. If the
system is set for Tone First, calls will call forward on Busy and No Answer.
Notes
● The caller can press the RING Soft Key on digital LCD telephones or press on digital or
electronic telephones to activate Call Forward on Voice Announce calls.
● OCA calls do not Call Forward No Answer in any case.
LED 15: ISDN Immediate DIaling
ISDN Immediate Dialing Without Subaddress enables the system to send out the SETUP message
to an ISDN line without waiting for the user to press the Start button and without waiting for the
time span between digits to time out. If LED 15 is On, ISDN Immediate Dialing is valid. If LED
15 is Off, the feature is Off (default).
ISDN Immediate Dialing is available for PRI calls on POTS, FX, OUTWATS and BRI POTS
calls. It is unavailable for senderized and cut-through calls on Tie lines, since the Tie lines are
provided for exclusive use. Immediate Dialing is not applicable for INWATS lines, since this
service line is for incoming calls only.
Since the ISDN Immediate Dialing begins as soon as the dialed number is confirmed as valid per
the NANP table below. ISDN subaddress dialing will be unavailable since the user will not have
the opportunity to enter a subaddress.
