Telephone Upgrades

Digital and electronic telephones can be upgraded for a number of features; there are no upgrades
for standard telephones. Each of these upgrades shares a circuit with the telephone that it is
connected to and is not considered a station. See

Digital Telephone Upgrades

This section describes how to upgrade and configure 2000- and 1000-series digital telephones for
features and options.
TAPI and Simultaneous Voice and Data Upgrades (RPCI-DI, PDIU-DI2 and PDIU-DI)
Both the 2000- and 1000-series digital telephones can be upgraded with an integrated data
interface unit to transmit and receive simultaneous voice and data calls. There are three versions of
the integrated unit:
RPCI-DI and PDIU-DI2 for the 2000-series telephones
PDIU-DI for the 1000-series telephones.
Asynchronous devices, such as PCs and terminals, can be connected to the standard RS-232
connector of the RPCI-DI or PDIU-DI2. Station users are able to transmit and receive RS-232 data
over the single-wire pair of the RPCI-DI or PDIU-DI2 equipped telephone.
TAPI/Data Communications Modes
The RPCI-DI can operate in two modes: the TAPI or the data communications mode. The mode is
changed by sending the appropriate control signal to the RPCI-DI from the PC to which the RPCI-
DI is connected.
TAPI Mode
In the TAPI mode, the PC connected to the RPCI-DI can place telephone calls. The PC can also
receive Caller ID, ANI, and DNIS information received by the RPCI-DI telephone. When in the
TAPI mode, the RPCI-DI is designed to be compatible with Microsoft TAPI application programs.
