System & Station
LED 07: Ring Transfer of CO Line Allowed
This option defines station operation for transferring [DN] and CO line calls. If Ring Transfer is
allowed, the system will allow “blind” transfers to busy or idle stations. The transferring station
may release a transferred call before the called party answers. If not allowed, the system will allow
supervised transfers only—the called station must answer before the transferring station releases.
If Ring Transfer is not allowed, immediate recall occurs if “blind” transfer is attempted. The
system denies Ring Transfer to stations in the Do Not Disturb (DND) mode, and immediate recall
will occur if attempted.
LED 06: CO Line Repeat Ringing
If selected, the incoming ringing timing pattern at a station will be the same as the CO line ringing
pattern. This is used mainly with Centrex or PBX systems which may vary the ring pattern to
distinguish between internal and external incoming calls, etc. If Standard Ringing is chosen, CO
line station ringing will cycle one second on, three seconds off regardless of the incoming ring
pattern. This ringing option may be undesirable for some COs.
LED 05: Incoming Call Abandon Timing
The amount of time between incoming CO line ring signals determines when the system will
discontinue (abandon) sending ringing tones to stations. The choice of six or eight seconds
depends on the line ring pattern. This assignment has no effect if the Line Repeat Ringing (LED
06) option is used.
LED 04: Dual-tone Multi-frequency (DTMF) Signal Time
DTMF signals sent out to CO lines can be either 80 or 160 msecs. in length. DTMF to QSTU2,
KSTU2, RSTU, RSTU2, RDSU/RSTS, PSTU, PESU ports (including voice mail ports) are not
affected by this assignment. See Program 10-2 for standard telephone port DTMF timing. This
program pertains to manual dialing or speed dialing from all Toshiba telephones, with the
following exception. When dialing manually from 2000-series telephones, signals last as long as
the buttons are pressed (minimum 80 msec.).
LED 03: Dial Pulse (DP) Make Ratio
Dial Pulse timing sent out to CO lines can be changed from the normal 40% make ratio to 33%.
This selection only applies to those CO lines assigned in Program 15 to signal dialing 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 CO lines experience the following situations: no
dial tone when a line is released and reseized immediately; or, when operating behind Centrex or
PBX, false hookflash signals are sent to the CO when stations release and reseize the same line
immediately.
LED 01: Tone First/Voice First Signaling-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 signaling mode to the other can be made by dialing an
additional digit of 1 from the calling station. Voice First applies to called [PDNs] only; [PhDNs]
are always tone first regardless of LED 01 setting.
