System Connection
Digital Telephones
The following provides information on how to connect digital telephones to the DK system.
NoteBefore proceeding, see warning and caution notes in “Telephone Installation”.
Digital telephones connect to the digital telephone ports via the MDF with standard twisted-pair 
jacketed telephone cable. If using 24 AWG cable, single-pair wiring is sufficient in most cases for 
digital telephones to operate effectively at up to 1000 feet from the system.
Digital telephones that are equipped with Integrated Data Interface Units or ADMs should have 
two-pair (or external power) to function effectively at this distance. This also applies to digital 
telephones supported by systems that must operate with battery reserve power – Chapter 5 – 
DK424 Installation, Table 5-2 on Page 5-5.
To accommodate the digital telephone line cord, the cable should be terminated in a modular 
station connector block (RJ-11) at the station location. The standard single-pair, modular digital 
telephone cord that is sent with the telephone is 7 ft. (the maximum allowed is 25 ft.).
NoteDigital telephone cable runs must not have cable splits (single or double), cable bridges 
(of any length), or high resistance or faulty cable splices.

 Electronic Telephones
The following provides information on how to connect electronic telephones to the Strata DK 
system.
NoteBefore proceeding, see warning and caution notes in “Telephone Installation” on Page 9-3.
Electronic telephones are connected to electronic telephone circuits in the DK40i Expansion Unit 
on the Electronic Telephone Interface Unit (PEKU) and the Standard/Electronic Telephone 
Interface Unit (PESU) via the MDF with standard twisted-pair jacketed telephone cable. Two-pair 
wiring, as a minimum, is required for telephone connection. However, three-pair wiring is 
recommended for some upgrades, such as OCA.
To accommodate the electronic telephone line cord, the cable should be terminated in a modular 
station connector block (RJ-11) at the station location. The standard two-pair modular electronic 
telephone cord length is 7 feet (the maximum allowed length is 25 feet). See Chapter 8 – DK40i/
DK424 Universal Slot PCB Wiring for more details.
If using 24 AWG cable, the overall length of the station cable run from the DK40i Base KSU to the 
telephone must not exceed 1,000 feet (305 meters).
Standard Telephones
The following provides information on how to connect standard telephones to the DK system.
NoteBefore proceeding, see warning and caution notes in “Telephone Installation” on Page 9-3.
Standard telephones connect to standard telephone circuits of the Standard Telephone Interface 
PCBs: RSTU, RSTU2, RDSU/RSTS, PSTU, PESU, KSTU2 (DK40i only), and QSTU2 (DK14 
only). Standard telephones connect to RSTU, RDSU/RSTS, PSTU or PESU via the MDF with 
standard twisted-pair jacketed telephone cable. (See single-pair wiring Chapter 8 – DK40i/DK424 
Universal PCB Wiring for more details.)
The standard telephone cable’s overall loop resistance, connected on- or off-premises, is 300 ohms 
maximum, (for PSTU, PESU, KSTU2, or QSTU2), 600 ohms for RSTU and RDSU/RSTS with 
-24VDC (no R48S), and 1200 ohms for RSTU and RDSU/RSTS with -48VDC (R48S installed on 
RSTU, RSTU2, or RDSU PCB), including the telephone resistance. This also applies to all devices 
connected to standard telephone circuits. 
A standard telephone connected off-premises via the telephone network should interface with 
OL13A, OL13B, or OL13C lines (or equivalent) and connect to an RJ21X, FIC jack or equivalent, 
(see Chapter 8 – Universal Wiring Diagrams and Table 5-3, “DK424 Network Requirements” on 
Page 5-6).
Telephone Wall Mounting
This section explains how to mount digital and electronic telephones to a wall or other vertical 
surface. See the manufacturer’s documentation for instructions on mounting standard phones.
Notes
lDigital telephones equipped with PDIU-DIs, RPCI-DIs or PDIU-DI2s cannot be wall 
mounted.
lElectronic and older digital telephones equipped with an HHEU1 can be wall mounted. 2000-
series digital telephones with headsets can only be wall mounted with an HHEU2.

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 Table 9-2 for more information.
Table 9-2 Telephone Subassembly Upgrades
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.

For more information, see Chapter 13 – Computer Telephony Integration. If an RPCI-DI only 
needs to support TAPI (and not data–see Notes below) it can be connected to any digital telephone 
circuit.
Data Communications Mode
In the data communications mode, data calls can be from a telephone with the 
DWD&DOO button 
and disconnected with the 
DWD5HOHDVH button. Digital telephones can have a 0RGHP button 
for reserving a modem or monitoring modem availability and status. These feature buttons are 
assigned to telephones with Program 39. Data and voice calls can be dialed from a terminal or PC 
using standard “AT” commands. 
Notes
l1000-series digital telephones with an RPCI-DI or PDIU-DI2 cannot be wall-mounted or 
equipped with an Add-On-Module (ADM) or DVSU for Speaker OCA. A 2000-series digital 
telephone with a PDIU-DI2 or RPCI-DI can support an HHEU at the same time, but cannot 
support a DVSU or ADM and can be wall-mounted.
lOnly PDKU1 circuits 1~7 can support RPCI-DI or PDIU-DI2s; all PDKU2 and Base Unit 
digital circuits can support PDIU-DI2 and RPCI-DIs.
lRPCI-DIs and PDIU-DI2s that support data communications mode, must be connected to 
digital telephone circuits that support 2B channels. The digital circuits that support RPCI-DI 
data communication are: 
DK14 – all digital telephone circuits.
DK40i – all digital telephone circuits except those installed in slot 17 and 18 of the expansion 
unit.
DK424 – see Tables 4-4 and 4-5 of the Chapter 4 – DK424 Configuration.
RPCI-DI/PDIU-DI2 Installation
See Figures 9-2, 9-5 and 9-6 and follow these steps:
1. Loosen the four screws on the digital telephone base and remove the base.
2. Insert the two integrated unit wire plugs into the connectors on the PCB in the telephone 
(observing the red wire for correct positioning).
3. Attach the integrated unit to the bottom of the phone. Install the PDIU-DI for 1000-series; 
install PDIU-DI2 or RPCI-DI for 2000-series phones. Secure with the four captive screws.
NoteRPCI-DI V2s require some modification when installed in DKT versions 1~3; RPCI-DI 
V2s in DKT version 4 or higher do not require any modification.
4. Remove the directory tray from the original telephone base and install it on the integrated unit 
phone base. Squeeze the tray on its sides so it bows slightly to remove and re-install.
5. See Chapter 5 – DK424 Installation, Table 5-2 on Page 5-5 for loop limits. Install a two-pair 
house cable (or external power) and a two-pair modular cord (supplied with PDIU-DI), if 
required for distance.
