Microphone (External Unit)
An external microphone (RFDM) can be connected to the DKT2020-FDSP digital telephone
enhancing full-duplex operation by virtue of the superdirectional characteristic of the
microphone. When this option is on, the internal microphone is disabled on all but Voice First
Handsfree Answerback calls and OCA calls. The external microphone is powered by the DKT and
does not need to be turned off when not in use.
Modem Button
This button enables a digital telephone user to reserve a modem from a pool or to switch from a
voice to a data call. Its LED indicates the availability of modems. The telephone must be equipped
with an Integrated PC Interface Unit (RPCI) for
0RGHP button applications.
Modular Handset and Line Cords
All Toshiba telephones are equipped with modular handset and line cords.
Modular Headset
Digital telephones may be optionally equipped with a modular headset jack by installing an HHEU
PCB.
Off-hook Call Announce (OCA)
OCA allows a station user to send a voice announcement to a busy digital or electronic telephone.
The call must be directed to a stations [PDN] or [PhDN]. OCA will not occur when the called
station is not the owner of the dialed [PDN] or [PhDN]. Only the [PhDN] owner telephone can
receive OCA on calls to the [PhDN].
In order for a station to receive OCA, the station must be assigned with OCA-receive capability in
the system database. Depending on system programming and hardware availability, the called
station can receive OCA in one of the following ways:
Handset Mode
An OCA announcement can be sent through the handset receiver to called party who is off-hook
and engaged in a conversation. Only digital telephone sets can have this feature. If the called
partys station has been programmed with Handset Mode and OCA-receiving capability, an OCA
warning tone (optional) and announcement can be sent to through the handset. Cordless digital
telephones will also receive the warning tone and announcement.
The called station user, while off-hook and engaged in a conversation, will hear the outside talking
party and the OCA calling party, but the outside talking party cannot hear the OCA calling party.
The called station user can hold down the
0LF button to respond and talk to the OCA calling party
through the handset; the outside talking party will not hear the response.
A digital telephone feature button can be programmed to work with push-on/off action. When
push-on/off is used, the outside party will hear MOH, if installed, when the called party talks
back to the OCA party; otherwise, the outside party hears nothing when excluded from the talk
path. Receiving handset OCA calls is available to digital telephones only; no special hardware
additions are required.
