Toshiba DK40I, dk14, DK424 3-86, LED 13 OCA Handset Warning Tone, LED 11: Busy Override BOV Tone

System & Station

Program 31 – Station Class of Service

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.
