TAPI

The Telrad DIGITAL family of systems supports TAPI,

Telephony Application Programming Interface. TAPI

provides a programming interface for the development

of telephony control applications. TAPI enables the

integration of shrink-wrapped software applications

with the DIGITAL family of systems.

Telrad's TAPI product is implemented in the DIGITAL

KEY BX, DIGITAL 400, and DIGITAL 1000 systems

via the DATALync data card, the TelradLINK protocol,

and the Telrad TAPI Service Provider Interface (SPI).

The SPI is installed in the personal computer and

translates the TAPI protocol to a Telrad protocol. TAPI

is supported in the Avanti 3025, Avanti 3020F, Avanti

3020H, Avanti 3015DF, Avanti 3015DH, and Avanti

3015H telephone sets. TAPI is also supported by the

SynopSys system with an DIGITAL Executive or

Speakerphone telephone set with a TelradLINK Data

Card.

TAPI allows a PC user to control telephone calls from

a PC running Windows 95, 98, or from a Windows NT

workstation, without having to touch the buttons on

the telephone set. With TAPI, you can use commonly

available Windows-based programs to perform a wide

range of telephone functions directly from the PC,

including dial, transfer, conference, disconnect, and

Caller ID screen pops. This is extremely convenient

for workers who require simultaneous use of the

telephone and the PC (see Figure 16).

TSAPI

TSAPI provides a two-way exchange of information,

between the computer network and the telephone

system, that supports information coordination and call

routing services required for callers and recipients.
