TAP (Flash)/Recall

When host system custom calling features are available via a hook-flash signal while on line, the TAP
button functions as a hook-flash button and generates a flash signal when the user presses it. When
custom calling signals are not available, the TAP button functions as a positive disconnect and recalls dial
tone when the user presses it. These features are mutually exclusive. The programmer sets the desired
function for the system by programming action. With single–line proprietary telephones, the Tap
function works for internal transferring only. An access code is required to activate custom calling
features
Telephony Services Application Programming Interface (TSAPI) Support
The DXP Plus provides support for TSAPI applications. These applications are Novell Telephony
Services* applications developed by third-party software vendors. TSAPI applications run independently
of the DXP Plus yet use its digital communications capability. The DXP Plus' Enterprise open
architecture interface (OAI) data port provides the hardware interface for the personal computer (PC) that
runs the TSAPI software program. Depending upon the TSAPI application and its functions, there may or
may not be a need to reprogram the DXP Plus' database feature parameters.

Through Dialing

An installer can connect external telephony equipment to the DXP Plus through a proprietary interface
device or through an IST port. When the programmer enables the through dialing feature, DTMF tones
that the external device generates pass through the interface equipment, the DXP Plus system, and any
line connection. Also see the paragraph titled Off Premise Extension.

Time And Date

The time designation will accept either a 12- or 24-hour format. Time and date appear on the LCD
speakerphone and the SMDA/SMDR record printout.

Timed And Immediate Recall

If a telephone user places a call on hold and fails to pick it back up within a preprogrammed time, the call
rings the user's telephone again. While only the telephone that put the call on hold rings, all other
telephones that share call appearance will flash the light for the held call at a hold recall rate.
Recall to an originating station also occurs from unanswered parked calls, transferred calls, and calls that
are camped-on. Plus, unanswered calls (ring no-answer calls) recall to the attendant or other
preprogrammed designation after exceeding a preprogrammed time-out period.
Any transfer attempt that fails will cause the held call to recall immediately. Examples of failed transfer
attempts are calling any of the following:
- non-existent extension
- partial extension number
- invalid extension number
A calling party continues to hear music on hold (if provided) throughout the recall sequence.
