INS-TIONIssue 1, November 1994Optional Data Port Modules
7.36All Inter-Tel/DVKkeysets maybe equipped with
optional Data Port Modules (refer to REPLACEMENT
PARIS for the part number). The Data Port Module con-
tains a four-conductor modular jack that can be used to
connect eirher a data device (such as a persona1 comput-
er with a direct-connect modem) or an LRA and an 
ex-
ternal signaling device (such as a loud bell, horn,
5ashing light, etc.) to the keyset.
7.37Install the Data Port Module as outlined below.
For a diagram, see Figure 349 on page 3-88.

Remove the keyset baseplate.
Unplug the line cord from its modular jack.
Remove the 
lo-pin shorting plug located on the
keyset control board.
Save the shorting plug by taping it to the inside of
the baseplate. The plug must be replaced if the
Data Port Module is later removed.
Align the Data Port Module over the three posts
protruding from the inside of the baseplate and
insert the screws (do not over tighten).
Plug the Data Port Module cable into the pins on
the 
keyset control board (where the shorting plugwas previously located). Make sure the cable
connector is securely seated.
Place jumper straps 
SPl, SP2, SP3, and SP4 onthe Data Port Module in the appropriate posi-
tions. Depending on how the Data Port Module
will be used, refer to one of the two possible set-
tings outlined in Figure 3-49.
(8)If connecting a mudem-qu?ppd%zta akvice, re-
fer to paragraphs 7.38 through 7.40.
If connecting a loud ringing adapter and an er-
tfimal signding a&ce refer to paragraphs 7.41
through 7.43.738To connect a modem-equipped data device:
The optional Data Port Module can be used to connect a
data device (such as a personal computer) equipped with
a direct-connection modem to a 
keyset. The data device
can be used with the 
keyset to communicate with remote
data equipment over voice channels being used for CO
or intercom calls. The data device’s modem must be ex-
ternally powered (or capable of operating on 
2omA of
loop current) and have an 
RJll CO trunk interface.
7.39The data device can be activated using the 
keyset
or an auto-dial modem. (For more details and an expla-
nation of monitoring or transferring the data connection,
refer to page 4-101 in
FEATUES). The data device is
disconnected whenever one of the following occurs: the
modem attached to the 
keyset disconnects from the call,
the called modem disconnects 
from the call, or the data
connection is transferred to the 
keyset’s primary voice
path and the call is disconnected.
7.40Install the data device as follows:
(1)Insert the modem line cord (which would nor-
mally be connected to a CO jack) into the modu-
lar jack on the 
keyset’s Data Port Module.
(2)
Ensure that the jumper straps on the Data Port
Module are set to the proper 
data device posi-tions. Refer to Figure 349.
(3)Plug the keyset line cord into the keyset’s modu-
lar jack and reattach the baseplate.

7.41To connect a 
Loud Ringing Adapter (LRA):
The optional Data Port Module can be used to comtect
external signaling equipment such as loud bells, horns,
flashing lights, etc. to a 
keyset. This application isusefnl
in areas where the normal ring tone of the keyset cannot
be heard, such as warehouses and loading docks. The
signaling device follows the normal ringing patterns of
the 
keyset.
NOTE: Since handsfree intercom calls may be difficultto hear in noisy areas, 
keysets with LRAs installed
should be programmed for handsfiee disable so that us-
ers are alerted to incoming intercom calls by continuous
double ring tones. (Refer to
FEMVRES, page 4-55.)
7.42An electromechanical LRA device is placed be-
tween the 
keyset Data Port Module and the external sig-naling equipment to provide the necessary interface
relay. Refer to page 2-26 for LRA device specifications
and recommendations. A diagram of a typical set-up is
shown in Figure 3-50 below.
7.43Install the LRA as follows:
(1)Using 24AWG wire, 
comtect the LRA device in-
put (coil circuit) to the RED and GREEN wires
(2)
(3)
(4)
Q
on a modular jack assembly. Some devices re-
quire that Polarity be observed between the LRA
input and the modular jack.
NOTE: In order for the 
LRA device to operate
properly, the maximum resistance 
Corn the mod-
ular jack to the 
LRA should be kept under 100Oh.
Attach a mod-to-mod line cord to the modularjack assembly and to the modular jack on the
keyset’s Data Port Module.
Ensure that the jumper straps on the Data Port
Module are set in the proper LRA positions. Re-
fer to Figure 3-49 on the previous page.
Connect the LRA device output (contacts) to the
signaling device according to the manufacturer’s
instructions. Use the appropriate gauge wire for
handling the current/voltage rating of the signal-
ing device.
Plug the 
keyset line cord into the modular jack on
the back of the 
keyset and reattach the baseplate.

NOTE: Each time the keyset rings, the Data Port Module provides 20-26mAof loop current to the LRA This
causes the 
LRA contacts to close and activates the signaling device. The LRA is not affected by the ring tone
or the ringer volume of the 
keyset. The LRA must be capable of operating on 2omA current (approximately
2OvDc).

D.IMX 256 DIGITAL DSS/BLF UNITINS-‘I’ION
7.44Up to 50 digital keysets can be equipped with up
to four digital Direct Station Selection/Busy Lamp Field
(DSWBLF) Units each. Bach single DSS/BLF Unit has
60 keys for directly accessing up to 60 numbers. The
numbers can be station extension numbers, hunt group
pilot numbers, or other system features.
NOTE: The system can have as many as 50 
keyset cir-
cuits equipped with 
DSS/BLF Units. For example, there
could be a maximum of 50 digital 
keysets (i.e., DKSCcircuits) equipped with up to four digital 
DSS/BLF
Units each. Or, there could be a maximum of 50 KSC orKSC-D circuits equipped with one analog 
DSS/BLF
Unit each. Or, there could be any combination of the two
using up to 50 
keyset circuits.
7.45Digital DSWBLF Units are physically attached
to and programmed to be used with specific digital key
sets. The units are powered by their own 
ACtransformer
and do not require a DKSC circuit that is separate fromthe 
keyset’s circuit. lf necessary, all 16 keysets con-
nected to the same Digital Keyset Card can be equipped
with up to four digital DSWBLF Units each.
NOTE: Digital 
keysets cannot be equipped with analog
DSS/BLF Units. Likewise, analog keysets cannot be
equipped with digital DSWBLF Units.
7.46Unpack and inspect the DSWBLF Units beforeinstalling them.
7.47Install each digital DSWBLF Unit as outlined be-
low. For diagrams of the installation, see Figures 
3-41
and 3-51 on pages 3-69 and 3-91.
(1)
(2)
(3)
Remove the baseplate on the back of the DSS/
BLFUnit.
On the connector board located in the baseplate,
plug the free end of the PCDPM-to-DSS inter-face cable into the main RS-232-C connector
(Jl). (The other end of the cable was previously
attached to the PC Data Port Module on the cor-
responding 
keyset; see also Figure 3-41 on page3-69.)
Plug the AC transformer cable into the power
connector (J4) on the baseplate connector board.(The transformer will later be plugged into an
AC power source.)NOTE: 
DSS/BLF Units always require their
own separate AC transformers. For a diagram ofAC transformer requirements, refer to Figure
2-2 on page 2-24.
(4)To attach a second DWBLF Unit to the first unit
(see Figure 3-41 on page 3-69):a. Plug one end of a DSS-to-DSS interface
cable into the secondary RS-232-C CoMec-
tor (J2) on the baseplate connector board in
the first unit.b. Remove the baseplate on the back of the
second DSWBLF Unit.
c.Plug the other end of the DSS-to-DSS inter-
face cable into the main RS-232-C connector
(11) on the baseplate connector board in the
second unit.
d.Plug the AC transformer cable into the powerconnector 
(54) on the baseplate connector
board in the second unit. (The transformerwill later be plugged into an AC power
source.)NOTE: 
If multiple DSS/BLF Units are
installed, each individual unit must be
equipped with its own AC transformer. 
lnaddition, the PC Data Port Module on the
corresponding keyset must be equipped with
its own AC transformer.
(5)To attach a third or fourth unit, repeat step 4.(6)
Perform the DSS/BLF Unit self-test:
a.While holding down the first two keys in row
one (extension numbers 100 and 101 in thedefault database), plug the main AC trans-
former unit into an available AC power
source. (DO NOTuse the outlet for the equip
ment cabinet.) All the keys should light up. 
If
an LED does not light, unplug the AC trans-
former unit and plug it in while holding down
the first two keys in row one (ext. 100 and
101). If the test fails again, replace the 
DSS/BLF Unit.
b.Press each key individually (in any order) to
remove the lit status. When finished, all keys
should be unlit. 
lf an LED does not go out,unplug the AC transformer unit and repeat
steps a and b. If the test fails again, replacethe 
DSS/BLF Unit. After all the keys have
been tested, it takes approximately five sec-
onds for the 
DSS/BLF Unit to return to nor-
mal operation.c. Replace the baseplate on the back of the
DSSBLF Unit.

m 7.49 Up to 50 lMX Direct Station Selection/Busy
Lamp Field 
@SS/BLF) Units can be installed on the
IMX 256 System. A Keyset Card (KSC or KSGD) can
support up to four analog units. Each 
DSS/BLF Unit has
60 keys for directly-accessing up to 60 numbers. TheI
munbtxs can be station extension numbers, hunt group
pilot numbers, or other system features.
NOTE: The system can have as many as 50 
keyset cir-
cuits equippedwith 
DSS/BLFUnits. For example, therecould be a maximum of 
50 KSC or KSC-D circuits
equipped with one analog DSS/BLF Unit each. Or, there
could be a maximum of 50 digital 
keysets (i.e., DKSCcircuits) equipped with up to four digital 
DSS/BLF
Units each. 
Or, there could be any combination of the
two using up to 50 
keyset circuits.
7.49As with 
keysets, analog DSS/BLP Units requirethree-pair cabling. After they are installed, the 
DSS/
BLP Units must be assigned in database programming
to be used along with designated 
keysets. As many of the
units as desired can be assigned to one 
keyset.I
NOTE: Analog keysets cannot be equipped with digital
DSS/BLF Units. Likewise, digital keysets cannot be
equipped with analog DSS/BLF Units.
7.50Unpack and inspect the 
DSS/BLF Units before
installing them. Each 
DSS/BLF Unit is shipped with a
7-foot line cord.
751Install each IMX DSS/BLP Unit as follows:CAUTION
If the power pair (W/BL, BL/W) is reversed, install-ing a 
DSS/BLF Unit will open the fuse (or asso-
ciated thermistor) on the KSC or KSC-D. If the card
has a fuse, this affects operation of all 
keysets, DSS/
BLF Units, and Attendant Computer Consoles con-
nected to that card.(1)Before connecting the 
DSWBLF Unit to the‘-\
appropriate Keyset Card, measure the voltage on1
j’the RED terminal of the modular jack assembly
with respect to the GREEN terminal. (The “com-mon” probe of the voltmeter is placed on the
GREEN terminal.) It must measure 
+3OVDC
(f2.OVDC). If -3OVDC is measured, check the
cabling for a reversed pair.
(2)Mount the modular jack assembly on the wall.
(3)Perform the 
DSS/BLF Unit self-test:a. Plug the line cord into the modular jack
assembly.
b.While holding down the key at the top of col-
umn one and the key at the top of column two,plug the line cord into the KSU jack on the
bottom of the 
DSS/BLP Unit. All the keys
should light up. If an LED does not light, re-move and replace the line cord. If the test
fails again, replace the DSS/BLF Unit.
c.Press each key individually (in any order) to
remove the lit status. When finished, all keys
should be unlit. If an LED does not go out, re-move and replace the line cord and repeat
steps b and c. If the test fails again, replacethe 
DSWBLP Unit. After all the keys have
been tested, it takes approximately 10 sec-
onds for the DSS/BLF Unit to return to nor-
mal operation.Page 3-92

u 7.52Up to 50 single or tandem Direct Station Selec-
tion/Busy Lamp Field 
(DSVBLF) Units can be installed
on the system. A 
Keyset Card can support up to four
units. Each single 
DSS/BLF Unit has 60 keys for direct-
ly accessing up to 60 numbers. The numbers can be ei-ther station extension numbers or hunt group pilot
numbers. The numbers can be station extension num-
1bets, hunt group pilot numbers, or other system features.753As with 
keysets, DWBLF Units require three-pair cabling. After they are installed, the 
DSS/BLP
Units must be assigned in database 
programminn to beused along with designated 
keysets. As many of the
units as desired can be assigned to one keyset.
NOTE: For information on installing the GX and GMX
DSWBLF Units, refer to appendixes A and B in the back
of this manual.
7.54Unpack and inspect the 
DSS/BLP Units before
installing them. Each 
DSS/BLF Unit is shipped with a
7-foot line cord.
7.55Install each 
Inter-Tel/DVKDSS/BLFUnit as fol-
lows:
(1)If installing a 
fadem unit, connect a second
modular jack assembly in parallel with the exist-
ing modular jack assembly. 
One jack will be used
for the 
first DSS/BLF Unit, while the other jack
will 
bc used for the second DSWBLF Unit.
(2)Before connecting the 
DSS/BLF Unit to the ap
propriate 
Keyset Card, measure the voltage on
the RED terminal of the modular jack assembly
with respect to the GREEN terminal. (The “com-mon” probe of the voltmeter is placed on the
GREEN terminal.) It must measure 
+3OVDC
(f2.OVDC). If -30VDC is measured, check the
cabling for a reversed pair.CAUTION
If the power pair (W/BL, BL/W) is reversed, in-
stalling a 
DSWBLF Unit will open the fuse (or as-
sociated thermistor) on the KSC-D. If the card has
a fuse, this affects operation of all 
keysets, DSS/BLF Units, and Attendant Computer Consoles
connected to that card.
13)Mount the appropriate modular jack assembly on
the wall.(4)Remove the four screws on the bottom of the
DSS/BLF Unit and remove the bottom cover.
(5)Locate the strap (J2) in the lower-right comer ofthe control board (see Figure 3-52 on page
3-94).
(6)If the unit will be 
u&g the programmed key
arrangement for DSSIBLF 1, place the strap in
the 
DSSl position (over the right two pins). If the
unit will be 
using the programmed key arrange-
ment for 
DSSIBLF 2, place the strap in the DSS2
position (over the left two pins).
NOTE: Tandem units should have one unit set
for 
DSSl and one unit set for DSS2. If tandem
units have the same strap settings, there will be
erroneous indications on the 
DSWBLF Units and
the 
keyset, and there may be errors throughout
the system.
(‘7)Perform the DWBLF Unit self-test:
a.Plug one end of the line cord into the modular
jack on the unit’s control board.
b. While holding down keys 100 and 110 (de-
fault), plug the other end of the line cord into
the appropriate modular jack assembly. All
the keys should light up. If an LED does not
light, remove and replace the line cord while
holding down keys 100 and 110 (default). Ifthe test fails again, replace the 
DSS/BLFunit.
c.Press each key individually (in any order) to
remove the lit status. When finished, all keys
should be unlit. 
Ifan LED does not go out, re-move and replace the line cord and repeat
steps a and b. If the test fails again, replacethe 
DSWBLF Unit. After all the keys have
been tested, it takes approximately 10 sec-

H.SINGLE-LINE SET AND PLAYBACK
DEVICE 
lNSTALLATIONSingle-Line Sets
7.57Single-line sets can be connected to either Sing-
le-Line Cards 
(SLCs) or Inward Dialing Cards @DC’s).
If connected to SLCs, single-line sets must be equippedwith AC ringers. If connected to 
IDCs, off-premises
single-line sets must be equipped with AC ringers, while
on-premises single-lines sets may be equipped with ei-
ther AC or DC ringers. Jumper straps on the 
IDC circuits
can be set for AC-ringing or DC-ringing. Refer to Figure
3-33 on page 3-53 for strap locations.
NOTE: To use 
SLCs and IDCs, a -4SV Module must be
installed in the power supply chassis. To use AC-ringing
single-line devices, a Ring Generator Module must alsobe installed.
7.58Enhanced Single-Lime Sets (ESLSs) and Sii-le-Line Instruments 
(SLIs): An internal jumper strap
can be moved to set the ringer for AC or DC. (An AC
ringer is required if the phone is used on an SLC or as an
off-premises extension on an IDC.) Be sure the strap isset correctly for the installation; incorrect installation
will cause damage to the phone. ESLSs also have a se-
lectable ring tone jumper strap (HI or LO) located on the
control board.
NOTE: 
IDCs do not support message waiting applica-
tions. If single-line sets with message waiting lamps are
installed on 
lDCs, the lamps will not function.759 Industry-standard single-line DTMF sets: If
equipped with AC ringers, they may bc installed on ei-
ther 
SLCs or IDCs. If equipped with DC ringers, they
must be installed on 
IDCs (and they must be used on-
premises).Playback Devices
7.60Playback devices can be used in place of single-
line sets on SLC or IDC circuits. These devices answer
an incoming call, play a recorded message, and auto-
matically disconnect from the call. They are installed
like single-line sets, using the same cabling and modular
jack assemblies. If the playback device responds to AC
ring signals and is installed on an IDC circuit, the circuit
must be strapped for AC ringing; if the device responds
to DC ring signals, the jumper strap must be set for DC
ringing. (Refer to Figure 3-33 on page 3-53.) A play-
back device uses the extension number that is associated
with its station circuit.
7.61Playback devices may be used with hunt groupsto speed call processing. Hunt groups can have two
types of special stations: announcement stations and
overflow stations. Either type of station can be equipped
with a station instrument that operates as a regular sta-
tion or with a playback device that answers the call, then
disconnects to transfer it back to the hunt group. Refer to
FEMURES, page 4-17, for more information.
7.62With the Exfemikd and Emnddplus Tl and
EdWsoftware packages, playback devices may also be
used in conjunction with the automated attendant fea-
ture. In this situation, the playback device answers the
call and plays a prerecorded message. After the mes-
sage, the caller is disconnected from the automated at-
tendant and hears pure system dial tone. During or after
the message, the caller may dial an extension 
number or
a hunt group pilot number. Refer to 
FEAWRES, page
4-12, for more information.
NOTE: For optimal performance, it is recommended
that voice mail units and automated attendant playback
devices be installed on IDC circuits rather than SLC cir-
cuits.Single-Line Set And Playback Device 
Installation-7.63 Inspect the 
ESLSs and SLIs before installing
them. If any parts are damaged or missing, contact Cus-
tomer Support.
7.64To install a single-line set or a playback device:
(1)If installing an ESZS or SLI:
a.
b.
C.
Remove the baseplate and open the phone to
expose the control board.
NOTE: The back cover of the ESLS does not
have to be opened to reach the straps.
Place the AC/DC jumper strap in the desiredposition. Also, on ESLSs, place the 
Hl/LG
(selectable ring tone) jumper strap in the de-sired position. (Refer to Figures 3-53 and
3-54 on the following pages.)NOTE: On ESLSs, do not move the 
JMP3
jumper strap from the NORM position.
Reassemble the phone.
(2)Before connecting a single-line set or playback
device to the system, measure the voltage on the
RED terminal of the modular jack assemblywith
respect to the GREEN terminal. (The common
probe of the voltmeter is placed on the GREEN
terminal.) It must measure 
-4ovDc (*2VDC).
If +40 is measured, check the cabling for a re-
versed pair.
(3)Mount the modular jack assembly on the wall.
