with a PDIU-DI2 can support an HHEU at
the same time, but cannot support a
DVSU. A 1000-series Digital Telephone
equipped with a PDIU-DI cannot support
an HHEU, ADM, or a DVSU for OCA.
2. PDKU1 circuits 1 ~ 7 only can support
PDIU-DI(2)s, but all PDKU2 and base unit
digital circuits, can support PDIU-DI(2)s.
3.13 PDIU-DI(2) Installation. Install the integrated
data interface unit (PDIU-DI for 1000-series and
PDIU-DI2 for 2000-series) in accordance with the
following steps:
1) Loosen the four captive screws securing the
digital telephone base and remove it (Figure
6-1).
2) Refer to Figure 6-4 for 2000-series telephones
or Figure 6-5 for 1000-series telephones, and
insert the two integrated unit wire plugs into
the connectors on the printed circuit board
(PCB) in the telephone (observing the red
wire for correct positioning).
3) Attach the integrated unit to the bottom of the
telephone and secure with the four captive
screws.
4) Remove the telephone number directory tray
from the original telephone base and install it
on the integrated unit telephone base. Bend
the tray by squeezing its sides so it bows
slightly to remove and re-install (Figure 6-4 or
6-5).
5) Check Table 8-D in Section 100-816-208;
install 2-pair house cable (or external power)
and 2-pair modular cord (supplied with PDIU-
DI) if required to achieve maximum distance.

3 DIGITAL TELEPHONE UPGRADES
3.00 This section describes how to upgrade and
configure 2000- and 1000-series Digital Tele-
phones for features and options.
3.10 Simultaneous Voice and Data Upgrade
(PDIU-DI2 and PDIU-DI)
3.11 Both the 2000- and 1000-series Digital Tele-
phones can be upgraded with an integrated data
interface unit to transmit and receive simultaneous
voice and data calls. There are two versions of the
integrated unit: the PDIU-DI and the PDIU-DI2.
The 2000-series telephones can only be equipped
with a PDIU-DI2, and the 1000-series telephones
can only be equipped with a PDIU-DI. Asynchro-
nous devices, such as personal computers (PC)
and terminals, can be connected to the standard
RS-232 connector of the PDIU-DI(2). Station us-
ers are able to transmit and receive RS-232 data
over the single wire pair of the PDIU-DI(2)-equipped
telephone.
3.12 Data calls can be manually dialed with a
Data Call button and disconnected with a Data
Release button on the telephone; or, data and
voice calls can be dialed from the keyboard of the
terminal or PC using standard "AT" commands.
Digital telephones may also be assigned a Mo-
dem button to reserve a modem or monitor mo-
dem availability and status. Assign feature buttons
to telephones with Program 39.
