11 NIGHT RINGING OVER EXTERNAL 
ZONE PAGE (RELEASE 3) 
11.00 
In systems shared by two tenants, each 
tenant’s CO lines can be assigned to night ring 
separate PIOU external page zones (Figure 8-25). 
This feature can also be used in one-tenant systems. 
11.01 With shared systems, for example, tenant 
l’s night ringing CO lines could be programmed to 
ring PIOU external page zones 1 and 2, while 
tenant 2’s lines could be programmed to ring zones 
3 and 4. In non-shared systems, night ringing CO 
lines can be assigned to ring all of the zones or just 
selected zones. 
11.02 The following programs must be used to 
assign CO lines to ring selected PIOU page zones: 
l Program 78-1: Assigns CO lines, tenant 1 and 
tenant 2, that will night ring over PIOU external 
page zones. 
l Program 15-5: Assigns CO lines to tenant 
tenant 2. Lines are initialized as tenant 1. 1 or 
l Program 77-1 (LEDs 10 w 13): Assigns tenant 1 
and tenant 2 CO lines to night ring specific PIOU 
external page zones. 
l Program 39: Assigns appropriate q , m 
(tenant I), and m (tenant 2) buttons to elec- 
tronic and digital telephones.

12 DATA INTERFACE UNIT 
INSTALLATION (RELEASE 3) 
12.00 General 
12.01 Release 
3 provides two types of Data Inter- 
face Units (DIUs) that enable digital telephone 
users to simultaneously transmit and receive data 
on the same PDKU station port and wire pair while 
communicating on a voice call. One unit, called the 
integrated DIU (PDIU-DI), becomes part of the 
digital telephone, replacing the telephone’s base; 
the other unit, is a small self-contained unit called 
the stand-alone DIU (PDIU-DS). Each DIU is 
powered by the PDKU it is connected to; therefore, 
no external power is required. 
12.02 Both DlUs can be connected to standard 
Electronic Industries Association (EIA) RS-232 
asynchronous serial data devices. EIA devices are 
divided into two categories: data communication 
equipment (DCE) and data terminal equipment 
(DTE). Common DCE devices are modems and 
some printers; common DTE devices are personal 
computers, ASCII terminals, and some printers. 
The PDIU-DI operates like a DCE and connects 
directly to DTE devices using standard RS-232 
cables. Depending on how its internal jumper plugs 
are configured, the PDIU-DS can either operate 
like a DTE and connect to DCE devices; or operate 
like a DCE device and connect to a DTE device. In 
most applications, DTE and,DCE devices exchange 
data between each other via the standard RS-232 
cable connection. 
8-38  
						

							12.03 DlUs can function with DCE and DTE de- 
vices at data speeds of up to 19.2 kbps. However, 
keyboard dialing using AT commands (from a PC 
or terminal connected to a DIU) is limited to 9600 
bps. A speed of 19.2 kbps can be achieved when 
dialing from a PDIU-DI-equipped digital telephone 
dialpad, but many PC software programs do not yet 
handle 19.2 kbps in an error-free manner. DIU data 
transmisssion speed is set by the first ATcommand 
that the DIU receives once it is in the command 
state; if manual dialing or receiving calls in the auto 
answer (default) mode, the transmission speed is 
transparent. 
IMPORTANT NOTE! 
To use the PDIU-DI or PDIU-DS with AT 
commands, communications software or a 
PC program that performs terminal emula- 
tion must be used. A Tcommands cannot be 
issued from the computer’s operating sys- 
tem prompt. 
12.10 Common DIU Connections 
12.11 
The block diagram in Figure 8-25 illustrates 
common DIU connections. In this example, PDIU- 
Dls are connected to personal computers (PC1 and 
PC2), and PDIU-DSs are connected to a serial 
printer and modems. The personal computer users 
can transfer files internally, print files on the same 
printer, and access the modem pool to send/re- 
ceive data to/from an external personal computer 
or dial up data service. 
12.12 To access these devices, a data call connec- 
tion must be established between the DIUs. This is 
accomplished by dialing the destination DIU from a 
digital telephone dialpad or from a PC keyboard 
using standard AT dial commands. PDIU-Dls share 
the same intercom numbers/ports with the digital 
telephone to which they are connected, while PDIU- 
DSs have their own. The INT and DATA LEDs on the 
digital telephone tell the system whether a voice or 
data call is being made: the INT LED, voice calls; and 
the DATA LED initiates data calls. When dialing from 
a keyboard with AT commands, B 0 1 is typed for 
voice calls, and 10 m w for data calls. 
12.13 Installation instructions for these devices 
are provided in Paragraphs 
12.40 thru 12.70. Call

paths and scenarios for five types of data test calls 
are provided in Paragraphs 12.82 N 12.86. Step-by- 
step data calling procedures are provided in the 
Data Interface User Guide in the Installation & 
Maintenance Manual, Operating Procedures. 
12.20 EIA Interface Leads (Signals) 
12.21 
Both DlUs operate with the ten standard EIA 
RS-232 interface leads (signals) on which signal- 
ing data is transmitted and received. DlUs connect 
to serial data devices with standard RS-232 cables, 
available from telephone supply stores (see Fig- 
ures 8-29 m 8-34). The PDIU-DVPDIU-DS requires 
ten signals for some applications, but can function 
with eight using modular cords and connectors with 
RJ45/DB25 adapters for other applications. If un- 
certain which signals are necessary for an applica- 
tion, all ten should be connected. 
IMPORTANT NOTES! 
1. The PDIU-DI is always a DCE device; 
the PDIU-DS may be a DTE or DCE, 
depending on how its internal jumpers 
(I- 9) are configured (see Figure 8-28). 
2. In the descriptions below, when a sig- 
nal is ON, its potential is 
about seven 
volts positive relative to signal ground 
(pin 7); when a signal is OFF, it is about 
7 volts negative relative to the signal 
ground (pin 7). 
l Frame Ground (FG, Pin 1): The FG signal (EIA 
circuit AA) is a protective or safety ground which 
is bonded to the PDIU-DI/PDIU-DS PCB. If re- 
quired by local codes, the FG should be con- 
nected to external ground. 
l Signal Ground (SG, Pin 7): The SG signal (EIA 
circuit AB) establishes the common ground ref- 
erence for all other PDIU and data device signals 
and must be wired for all applications. 
l Transmit Data (TD, Pin 2): DTE devices trans- 
mit and DCE devices receive data on the TD lead 
(EIA circuit BA). Before the DTE device can 
transmit the TD signal, the RTS, CTS, DSR, and 
DTR signals (all discussed below) must be ON. 
The TD signal is OFF in the idle state. 
l Receive Data (RD, Pi’n 3): The DCE -device 
transmits data to the DTE device on the RD lead 
(EIAcircuit BB); the DTE receives dataon the RD. 
8-39  
						

							INSTALLATION-PERIPHERALS 
SECTION 200-096-208 
FEBRUARY1991 
l Request to Send (RTS, Pin 4): Some DTE de- 
vices send an RTS signal (EIA circuit CA) to the 
DCE devicewhen they are ready to transmit data 
on the TD lead. If the DTE device does not 
generate the RTS signal, the DIU DIP switch 
SWI-4 should be set ON to inform the DIU. 
Sometimes, the DTE/DCE device may use RTS/ 
CTS for Ready/Busy type flow control, in these 
cases DIP switch 
SWI-4 should be OFF (see 
Figure 8-26 for DIP switch information). 
l Clear to Send (CTS, Pin 5): The DCE device 
sends the CTS signal (EIA circuit CB) which 
indicates that it is prepared to transmit data to the 
line side. The DCE device sends this signal only 
when it receives the RTS signal from the DTE 
device. Sometimes, the DTE/DCE device may 
use RTS/CTS for Ready/Busy type flow control; 
in these cases, dip switch 
SWI-4 should be OFF 
(see Figure 8-26 for DIP switch information). 
l Data Set Ready (DSR, Pin 6): When connected 
to the communication channel and prepared to 
exchange control characters to initiate data 
transmission, the DCE device sends the DSR 
signal (EIA circuit CC) to the DTE device. If the 
PDIU DIP switch 
SWI-2 is set ON, DSR will be 
ON continuously; if the switch is set OFF, DSR 
follows DTR (if DSR is ON, DTR is ON, etc.) 
SW1 -2 should be OFF in most cases (see Figure 
8-26 for DIP switch information). 
l Data Carrier Detect (DCD, Pin 8): The DCE 
device sends the DCD signal (DCD, Pin 8) when 
receiving the carrier signal on the line side. 
Before transmitting or receiving data, most DTE 
devices require that the DCD be ON. If the carrier 
signal is removed by the remote end or lost due 
to a fault condition on the line, the DCE notifies 
the DTE device by an OFF condition with the 
DCD signal; PDIU DIP switch 
SWI-2 is set ON to 
set the DCD ON continuously; if set OFF, the 
DCD signal will only be ON when connection 
between two DlUs is established and OFF when 
aconnection is not established. 
SWI-2 isset OFF 
when the DTE/DCE uses the DTR/DSR signals 
for Ready/Busy flow control (see Figure 8-26 for 
DIP switch information). 
l Data Terminal Ready (DTR, Pin 20): The DTE 
device sends the DTR signal (EIA circuit CD) to 
the DCE device, prompting the DCE device to 
open the communication line. The line is closed 
and the call disconnected when the DTE device quits sending the DTR signal. DTR may be sent 
any time to indicate that the DTE is ready to 
transmitorreceivedata.DIPswitchSWl-ishould 
be set OFF in most cases (see Figure 8-26 for 
DIP switch information). 
l Ring Indicator (RI, Pin 22): The RI signal (EIA 
circuit CE) is sent by the DCE device to the DTE 
device. Whenever the DCE device receives a 
ringing signal on the line side, it turns the RI 
signal ON. If DIU DIP switch 
SWI-3 is set ON, 
the RI signal will be on continuously if ringing; if 
the switch is set OFF, the RI signal will be one 
second ON/three seconds OFF when the DIU 
detects ringing signal. 
12.30 DIP Switch Options 
12.31 
The PDIU-DI and the PDIU-DS each have a 
four-control DIP switch which can be configured for 
signaling options. The switch is located on the 
bottom of the PDIU-DI, and on the back panel of the 
PDIU-DS (see Figure 8-26). 
l SWI-1 : Normally this switch is set ON to discon- 
nect devices from DlUs automatically. The con- 
nection is maintained if data is exchanged be- 
tween the device and the DIU within eight to nine 
second intervals. If 
SWI-1 is OFF on the called 
and calling DIU, data calls will remain connected 
until released manually. 
IMPORTANT NOTE! 
SWl-1 ON, auto disconnect, is in effect 
only for D/Us that have AT commands 
enabled in Program 20 (LED 02 ON). 
l SWI-2: This switch is placed in the ON position 
when the PDIU-DI (or PDIU-DS configured like a 
DCE) must hold DCD and DSR ON continu- 
ously. If 
SWI-2 is OFF, DSR follows DTR and 
DCD will be ON only when the DIU is connected 
on a data call to another DIU. 
SWI-2 should be 
OFF on a DIU when it is connected to a personal 
computer that uses a communications software 
program to establish data calls with AT com- 
mands. 
l SWI-3:The PDIU-DI (or PDIU-DSconfiguredas 
a DCE) sends the Ring Indicate (RI) signal to the 
computer to tell the computer (DTE) that the 
PDIU isreceivinganincomingcall.SWl-3should 
be ON for the DIU to send RI steady, and OFF to 
send at one second ON/three seconds OFF in- 
tervals. 
8-40  
						

							INSTALLATION-PERIPHERALS 
SECTION 200-096-208 
FEBRUARY1991 
l SWI-4: This switch is placed in the ON position 
if the computer does not output the RTS signal. 
Sometimes, the DTE device may use RTSKTS 
for Ready/Busy flow control, in these cases 
SWl-4 should be OFF. In this case the DCD 
signal of the calling DTE is used as the RTS lead 
of the called DTE and the DCD signal of the 
called DTE is used as the RTS signal of the other 
DTE. In this case a signal which stops the DTE 
from transmitting data (usually the CTS lead) 
should be cross-connected to the DIU’s DCD 
signal. Consult the DTE device or application 
software documentation to determine which type 
of flow control is required. 
12.40 PDIU-DI to Personal Computer (PC) In- 
stallation 
12.41 
The PDIU-DI always functions as a DCE 
device; it transmits data on the Receive Data lead 
(RD) and receives data on the Transmit Data lead 
(TD). Most personal computers function as a DTE 
device; PCs transmit data on the TD lead and 
receive data on the RD lead. Follow the steps below 
to install the PDIU-DI to a DTE, PC: 
NOTES: 
1. Use the steps below when installing an 
ASCII terminal, personal computer, or any 
other DTE device to a PDIU-DI. 
2. The PDIU-DI can connect to a DCE 
computer or any other DCE-type device 
using a specially configured W-232 cable 
or adapter; but this application is rarely 
required. 
1) Install the digital telephone that is to be 
equipped with PDIU-DI per the instructions in 
Section 200-096-207 and the drawing in Sec- 
tion 200-096-209. 
2) Install the PDIU-DI under the digital telephone 
per the instructions in Section 200-096-207. 
NOTE: 
The PDIU-DI always operates as a DCE de- 
vice; therefore, unlike the PDIU-DS, it has no 
internal jumpers. 
3) Connect the appropriate RS-232 cable be- tween the PDIU-Dl’s DB-25female connector 
and the PC’s appropriate asynchronous serial 
communications port connector (C‘OM port). 
IMPORTANT NOTE! 
Check the PC manufacturer’s serial com- 
munica tion port interface documentation 
for correct RS-232 pin requirements; re- 
quirements vary with each manufacturer. 
The number of ElA RS232signals required 
(8, 9, or IO wires) depends on the applica- 
tion. When EIA signal requirements are not 
known, connect the 10 EIA signals listedin 
Paragraph 12.20. Figures 8-29 and 8-30 
provide diagrams for connecting RS-232 
cables between PDIU-Dls and Toshiba lap 
top, and IBM, XT and AT PCs. 
4) SetthePDIU-DI DIPswitch (SWl-I-4)forthe 
desired application. Figure 8-26 shows the 
DIP switch locations and Paragraph 12.30 
describes switch functions. 
5) Access Program 20 to configure the PDIU-DI 
for DTE-type connection and 
Program 39 for 
data button assignments of the digital tele- 
phone connected to the PDIU-DI. 
Program 20 
l The port number entered for the PDIU-DI 
in 
Program 20 is the port number of the 
digital telephone to which the PDIU-DI is 
connected. 
l LED 01: Should always be ON for PDIU- 
DI ports. 
l LED 02: Should be ON for PDIU-DI ports,

display screen. Frequently, it is difficult to 
determine the full extent of these re- 
quirements; so it is recommended to turn 
LED 02 ON. See the Data Interface User 
Guidein the Operating Procedures of the 
Installation and Maintenance Manualfor 
information regarding D!U ATcommands 
and result codes.

used for voice calls only. 
12.50 PDIU-DS To Printer Installation 
12.51 The STRATA DK (Release 3) enables serial 
printers (laser, dot matrix, or other types) to be 
connectedtostand-alonedatainterfaceunits(PDIU- 
DSs). Digital telephones equipped with PDIU-Dls 
can share access to these printers. Serial printers 
operate as DCE or DTE devices, depending on the 
vendor; the PDIU-DS can be connected to either 
type, since it can be configured as a DTE or DCE 
device. (The PDIU-DS comes from the factory 
configured as a DCE device.) Follow the steps 
below to install the PDIU-DS to a serial printer. 
NOTES: 
1. Only serial printers (not parallel) that con- 
form to EIA RS-232signaling requirements 
can be connected to PDIU-DSs. 
2. In rare applications, it may be desired to 
connectprinters to PDIU-Dls. Refer to the 
printer’s ins talla tion instructions. 
1) Consult theserial printer’s documentation and 
determine if the printer operates as a DCE or 
DTE device: 
l If the printer is a DCE device: Disas- 
semble the PDIU-DS and configure it to 
operate like a DTE device by placing the 
jumper plugs 
(PI - P9) in the “B-C” (MO- DEM) position. Reassemble the PDIU- 
DS, and mark “B-C” on the bottom iden- 
tification label for future reference. (Para- 
graph 12.70 provides PDIU-DS disas- 
sembly/assembly instructions, and Figure 
8-28 provides jumper plug information.) 
l If the printer is a DTE device: It may not 
be necessary to disassemble the PDIU- 
DS, since it comes direct from the factory 
configured as a DCE device. However, if 
uncertain, disassemble the PDIU-DS and 
verify that jumper plugs 
(Pl - P9) are in 
the “A-B” (DTE) position. Reassemble 
the PDIU-DS and mark “A-B” on the 
bottom identification label for future ref- 
erence. (Paragraph 
12.70 provides PDIU- 
DS disassembly/assembly instructions, 
and Figure 8-28 provides jumper plug 
information.) 
2) Connect the PDIU-DS to the appropriate PDKU 
circuit perwiring diagrams in Section 200-096- 
209 and information provided in Section 200- 
096-207. 
3) Connect the appropriate RS-232 cable be- 
tween the printer and the PDIU-DS (see Fig- 
ure 8-31 for an example printer cable connec- 
tion). 
4) If steps 2 and 3 are done properly, the Power 
and Ready LEDs on the PDIU-DS should light 
when the printer is turned on and ready. 
5) Set the PDIU-DS DIP switch 
(SWI-1 - 4) for 
the desired application. Figure 8-26 shows the 
DIP switch locations and Paragraph 12.30 
describes switch functions. 
IMPORTANT NOTE! 
Check the printer’s serial documentation 
for correct RS-232 pin requirements. The 
requirements vary with each manufacturer. 
6) 
Use Program 20 to configure the PDIU-DS to 
connect to a serial printer (see Pogramming 
Section 200-096-302 for instructions and 
record sheets). 
l LED 01: Should al’ways be-ON for PDIU- 
DS ports.

stations can only make datacalls to DlUs 
in the same data security group. 
7) Program 22should be used to configure PDIU- 
DSs to hunt if more than one PDIU-DS con- 
nected to the same printer/server. lines and modems, it is recommended to connect 
modems to PSTU/PESU standard station ports in 
a modem pool configuration. The RS-232 side of 
the modem connects to the PDIU-DSwith standard 
RS-232 cables; the PDIU-DS line side (RJ-11 con- 
nector) always connects to its own individual PDKU 
port. Use the instructions below to install modems 
to PDIU-DSs. 
1) Configure the PDIU-DS as a DTE device: 
Disassemble the PDIU-DS and place jumper 
plugs 
Pl y P9 in the”B-C’position (MODEM). 
Reassemble the PDIU-DS and mark “B-C” on 
the bottom identification label for future refer- 
ence. (Paragraph 12.70 provides PDIU-DS 
disassembly/assembly instructions and Fig- 
ure 8-28 provides jumper plug information.) 
2) Connect the PDIU-DS to the appropriate PDKU 
circuit per the wiring diagrams in Section 200- 
12.60 PDIU-DS To Modem Installation 
12.61 
With Release 3 software, STRATA DK en- 
ables asynchronous-type (not synchronous) mo- 
dems to be connected to PDIU-DSs. This allows 
PDIU-DI equipped digital telephones that are con- 
nected to personal computers, terminals, and other 
devices to share access to a modem or modem 
pool. 
IMPORTANT NOTE! 
Modems must be “smart modems” that 
respond to ATcommandsandreturn result 
codes. Modems are customer-supplied. 
12.62 A modem(s) can be accessed internally for 
outgoing data calls or externally for incoming data 
calls. Modems operate as DCE devices; so PDIU- 
DSs that are connected to them must be configured 
to operate like a DTE device. In the example 
installation in Figure 8-25, the line side of the two 
modems are connected to PSTU/PESU ports to 
establish a modem pool; however, the line side of 
modems could be connected directly to a dedicated 
CO line. If modems are connected directly to tele- 
phone network CO lines, automatic transfer of CO 
line voice calls to system modems (data call) will 
not function as described in the Data Interface User 
Guide. For best operation and utilization of CO 
096-209. 
3) Connect the appropriate RS-232 cable be- 
tween the modem and the PDIU-DS. Figure8- 
32 shows an example PDIU-DS to “smart 
modem” RS-232 connection. 
IMPORTANT NOTE! 
All ten PDIU-DS EIA leads (signals) should 
be connected to the modem. Consult the 
modem’s documentation for correct RS- 
232 pin requirements; the requirements 
may vary with each manufacturer. 
4) Connect the line side of the modem to a PSTU 
or PESU standard telephone circuit or a 
dedicated CO line (consult the modem’s 
documentation to install the it to a CO line). 
Section 200-096-209 provides PESU/PSTU 
station port wiring information. 
5) Set the PDIU-DS DIP switch 
(SWl-1 - 4) for 
thedesiredapplication. Figure8-26shows the 
DIP switch location and Paragraph 12.30 
describes switch functions. 
6) Use the programs below to configure the 
PDIU-DS to connect to an asynchronous 
modem (see programming Section 200-096- 
302 for explanations and record sheets).

12.70 PDIU-DS Disassembly and Assembly 
12.71 
To set the jumper plugs (Pl - P9) on the PCS 
inside the PDIU-DS for DCE or DTE operation, the
