System & Station
Program 31 – Station Class of Service
3-86 Strata DK Programming 5/00
LED 15: Toshiba Stratagy, Stratagy DK and/or VP Integration (A Tone/D Tone)
When enabled (LED 15 On), sends an answer tone (DTMF A tone) to the Toshiba voice mail
system when a station answers, and a disconnect tone (DTMF D tone) when a station disconnects.
This allows Toshiba voice mail systems to respond quickly rather than waiting during long time-
outs. If the Central Office (CO) provides an Automatic Release (AR) signal (sometimes referred to
as Calling Party Control or Loop Supervision), D tone is also sent to disconnect VM ports when
outside callers hang up (see Program 15-0 and 15-3).
LED 14: Off-hook Call Announce (OCA) Handset or Speaker
If a station is enabled to receive OCA (Program 31, LED 03 On), LED 14 defines which type of
OCA the telephone should receive: Headset/Handset (LED 14 On) or Speaker (LED 14 Off).
Digital Telephones: Speaker OCA requires a DVSU and a special Program 03 code. Only digital
telephones can receive Handset OCA. Handset OCA does not require DVSU or any other special
hardware.
Electronic Telephones: Speaker OCA requires a HVSU and three-pair wiring. Headset OCA does
not require these items; Electronic or standard telephones cannot receive Handset OCA.
LED 13: OCA Handset Warning Tone
This option enables (LED 13 On) or disables (LED 14 Off) a warning-tone (one-second tone burst)
for digital telephones that receive Headset OCA. Does not apply to Speaker OCA.
LED 12: Pooled Line Button Operation, No Flash if No Ring
When enabled (LED 12 On) on telephones assigned to ring in Programs 81~89, incoming line
calls in pooled line groups only flash on
3RROHG/LQH buttons. When disabled (LED 12 Off), the
Pooled Line LED flashes when an incoming line call is received – even if the telephone does not
ring.
LED 11: Busy Override (BOV) Tone
Digital or Electronic Telephones: If a [DN] is busy and receives a call on an idle [DN] or CO
button from another station or an outside line then BOV tone is sent. BOV tone can be continuous
muted one-second rings (LED 11 On) or two muted one-second rings three seconds apart (LED 11
Off).
If all the [DN] button appearances of the called [DNs] are busy, the call will camp-on and the
telephone receives two muted rings (camp-on tone) three seconds apart (only if LED 01 is On for
the telephone in Program 34).
This BOV feature does not apply to CO lines that are ring transferred to a busy telephone - with or
without an idle [DN] or CO
/LQH button. In this case, the call is a camped-on call to the busy
telephone.
BOV and Camp-on muted ring tone frequency for digital and electronic telephones:
1209Hz/modulated by 10Hz on CO line calls; 1209Hz/unmodulated on station-to-station calls.
Standard Telephones: This feature does not apply to Camp-on tone sent to standard telephones.
Standard telephones only receive two Camp-on tone bursts - three seconds apart, regardless of this
BOV Tone feature’s setting. Also, you must run Program 34 to enable a standard telephone to
receive Camp-on tone. Camp-on tone is sent when the busy standard telephone receives a
transferred CO line call and when the busy standard telephone receives a direct call from a station
or CO line.
