machine (or similar device) attached to the 
HUNT connector. 
HOXB: An external module that serves as 
an interface between the HKSU and con- 
ventional, single-line telephones or off- 
premises extension 
(OPX) lines. Each 
HOXB PC8 serves two extensions; one 
HOXB per system. An HOXB will operate 
with either DTMF or rotary-dial telephones. 
An auxiliary ring generator/power supply 
(MRGU) is required for the HOXB. 
HSMB: Serves as an interface between the 
HKSU and a printer or storage device used 
for the SMDR feature. The module is 
equipped with an RS-232C interface and 
connects to the left side panel via two 
supplied 8-wire modular connectors (one 
HSMB per system). 
HDCB: An optional module connected to the 
HKSU at EKT 13 or 14 that allows up to 
three door phone/monitor stations (MDFBs) 
to ring pre-selected EKTs. The HDCB has 
three outputs (A, B, C), which are modular 
connectors for the three MDFBs. (Outputs 
B and C may be used for the Door Lock 
and Alarm features, respectively.) 
Station Equipment 
The principal components of the lo-key 
electronic key telephone (Figure 5) are: hand- 
set, dial pad, handsfree answerback (HFU) 
nicrophone, 
microphone control key (m; 
speaker and m key, two volume controls, 
an m key, and nine CO/PBX line or fea- 
the exception of the four permanently dedi- 
cated keys and the m key, the remaining 
feature keys can be. assigned to any one of 
several keystrip modes by programming. (An 
identical EKT is available as a speakerphone.) 
The single-line EKT (Figure 
dedicated keys 
( 
and an intercom/CO line key, which 
is not labeled. 
A lo-key BLF EKT (Figure 7) provides the 
same features as those listed above, plus an 
LED indication of which stations are in use. 
The 20-key EKT (Figure 8) provides the 
same features as those listed in the above two paragraphs, and has 10 additional fea- 
ture keys. 
A 20-key Liquid Crystal Display (LCD) EKT 
(Figure 9), incorporating the same features as 
those listed above for the 2O-key, may be 
located at any or all of the stations. The 32- 
character alphanumeric Liquid Crystal Display 
(12-digit display in current release) provides 
station-to-station message waiting capabili- 
ties. Other features include an accurate 
clock/calendar in its idle state; and elapsed 
time, dialed number, calling station and CO 
line are displayed 
acters only. 
All EKTs are 
mounting, feature 
equipped with a by the lower line of char- 
easily converted for wall 
modular handset cords, are 
second modular connector 
for headset connection (except the single-line 
EKT), and are connected to the system via 
2-pair modular line cords. 
The optional door phone/monitor station 
(Figure 13) allows a door phone unit to dis- 
tinctively ring pre-selected station(s). When a 
station dials an individual door phone, a cir- 
cuit providing monitoring capabilities on the 
intercom is established. This option requires 
station 13 or 14 to be replaced by a door 
phone control unit (HDCB) and up to three 
door phone units (MDFBs). One door phone/ 
monitor can be replaced by an alarm control 
circuit and one by a door lock control circuit.

placing any faulty component (PCB, sub- 
assembly, telephone, etc.) and returning it to 
the manufacturer for repair. 
07 FEATURES and OPERATION 
General 
This section contains brief descriptions of 
the features listed earlier in Tables B and C 
and some associated operating instructions. 
Detailed operating instructions can be found 
in the EKT 
USER GUIDE. 
Standard Features 
System 
All Call Voice Page: 
Dialing a 2-digit access 
code permits a station user to page via all 
idle EKT speakers simultaneously. The sys- 
tem can also be programmed to include 
the Ext,rnal Page feature in an All Call 
Page. 
Automatic Dialing-System: Allows 40 num- 
bers to be stored in the system’ memory. 
After selecting an outgoing line, any sta- 
tion user can cause one of the stored 
numbers to be outpulsed 
1 by dialing the 
proper access code. 
Automatic Hold Recall: A CO line placed on 
hold by any station will recall that station 
after a programmable period of time. A 
different time period can be selected for 
each station. 
Automatic Release from Hold: The system . 
automatically releases held CO lines if a 
disconnect signal is received from the cen- 
tral off ice. 
CO 
Call Pickup: Using a dial code, allows 
CO call pickup from another station. 
Conference (Multi-Station): Non-amplified 
conferencing is permitted. to a maximum of 
four stations and one CO 
line. (Conferenc- 
ing is not amplified.) 
Conference (Multi-CO Line): The system 
will conference two CO lines and up to 
three stations. (Conferencing is not ampli- 
fied.) 
Distinctive Ringing: CO and intercom calls 
are distinguished by different ringing tones. 
DTMF and Dial Pulse CO Line Compatible: 
The system will interface 
with either 
DTMF or rotary-dial pulse CO lines on a 
line-by-line basis as determined by system 
programming. 
External Page Interface: A 600-ohm con- 
nection point is provided for a customer- 
provided external amplifier/speaker. The 
SEPU (see External Page Amplifier) can be 
mounted in the HKSU when only a cus- 
tomer-provided external speaker is used; 
the output impedance will be 8 ohms. This 
page circuit can be accessed as part of 
the All Call Voice Page feature. 
Flexible Key Assignment: Allows each EKT 
to be programmed for optimum use of its 
CO/PBX or feature keys. 
Flexible Line Ringing Assignment: A pro- 
grammable ring or no ring option is pro- 
vided for each line selectively by each sta- 
-lO-  
						

							tion. Each line may be programmed to ring 
a maximum of eight stations. 
Forced Account Code: Requires selected 
station(s) to dial an account code prior to 
dialing a number. The account code is re- 
corded with call details on the SMDR re- 
port. 
Group Paging: Special 2-digit access codes 
(81, 82, 83 or 84) permit voice paging to 
one of four zones. Zone assignment is via 
software and is totally flexible. Paging is 
via the speakers of idle EKTs. 
Live System Programming: Live system pro- 
gramming is accomplished without service 
interruption to other station users by plac- 
ing the system in the special programming 
mode and inputting data via station 17. 
Station 17 is the only station that is 
“down” during programming. 
Message Waiting: Any station (including the 
designated Message Center) can set a 
Message Waiting LED at any station with 
the Message Waiting LED of that station. 
The called station cancels the LED by lift- 
in the handset and depressing the 
* key (not available on single-line 
EKT). Also see Flash key. 
MF Signal Time (160180 ms): The standard 
MF dial signal time is 80 milliseconds, but 
it may be extended to 160 milliseconds, if 
required by the CO or to activate remote 
equipment. 
Multiple Simultaneous Handsfree Intercom 
Paths: 
Two intercom paths are available in 
the system. Both intercom lines are able 
to carry handsfree conversation simultane- 
ously. 
Music-On-Hold Interface: An interface is 
included for a customer-provided music 
source. CO lines placed on hold will be 
connected to this source. In addition, this 
music may also be broadcast from EKT 
speakers and external page when the 
background music programming options are 
selected. 
Night Ring Answer Code: A night ringing 
call may be answered from any station via 
a dial code. 
-ll- STRATA Vls 
GENERAL DESCRIPTION 
NOVEMBER 1986 
Night Ringing Over External Page: 
As a 
programmable option, while the night 
mode is active, 
a system-generated ring 
tone will be transmitted via the external 
speaker whenever any line rings. 
Night Transfer: On a programmable optional 
basis, the system can function with two or 
three ringing patterns. If three patterns are 
selected, they are designated DAY, DAY 2, 
and NITE. If the two-pattern mode is se- 
lected, DAY and NITE designations are 
used. In both cases, the ringing 
modes are 
selected with the 
q key on station 10. 
_ 
Non-blocking Dialing: Dialing is permitted 
on intercom and all CO lines simultane- 
ously. 
Outgoing Call Restriction: Any station can 
be selectively restricted from originating 
calls on any or all CO lines. However, the 
station may still receive calls on the re- 
stricted line(s). 
PBX Compatible: All of the system’s fea- 
tures, such as Toll Restriction and Auto- 
matic Dialing, are compatible with PBX op- 
eration. 
Privacy/Non-Privacy: A private system pre- 
vents other stations from accessing the in- 
tercom or CO lines that are already in 
use. A non-private system provides confe- 
renting on the CO and intercom lines. 
Private CO Lines: Restrictions may be pro- 
grammed into the system so that selected 
CO line(s) will appear only on selected 
station(s). 
Relay Service: The VMAU PCB is equipped 
with relays that provide the fotlowing sig- 
nals for external equipment: 
4 
t-4 External Page: ‘The relay is activated 
whenever the external page circuit is 
accessed. A dry “make” contact is pro- 
vided for control of background music 
on external page. This is required only 
when an external page amplifier is 
used. 
Night Relay S&vice: The relay will 
provide a dry “make” contact at the 
NR 
terminals on the left side panel. A strap 
option on the VMAU allows the NR re- 
lay to function in one of two modes:  
						

							STRATA Vie 
GENERAL DESCRIPTION 
NOVEMBER 
1986 
1) Answering Machine Control: If the 
strap remains intact, the relay is op- 
erated continuously when the system 
is in night service. This mode is in- 
tended for indirect control of an an- 
swering machine. 
2) 
Night Bell Control: If the strap is 
cut, the relay pulses at a l-second 
on/3-seconds off rate whenever the 
system is in Night Transfer mode 
and an incoming call is ringing the 
system. This mode is intended to be 
used for indirect control of an exter- 
nal night bell. 
Toll Restriction (6-digit): Selectively pro- 
grammed on a station class of service ba- 
sis. The system performs toll restriction by 
analyzing the first 6 or 3 digits (area/ 
office code) dialed. Simple restriction by 
rejecting the numbers 0 and 
1 can be 
programmed on a per-station basis, if de- 
sired. 
Toll Restriction Override by System Auto- 
matic Dialing: 
A programmable system 
feature that permits numbers stored by the 
Automatic Dialing-System feature to be 
called by toll-restricted stations. 
Voice or Tone Signalling: A programmable 
system feature that optionally selects either 
tone ringing or voice page as the primary 
method of intercom call signalling. The 
calling station, however, may choose the 
alternate method by dialing 0 following the 
station number. 
Wall Mountable 
signed for wall 
HKSU: The HKSU is de- 
mounting only. 
Station 
Automatic Callback (Intercom): 
Permits a 
station user who encounters a busy sta- 
tion on intercom to request a callback by 
depressing the dedicated key. The system 
then monitors the called station and sig- 
nals the caller when that station becomes 
idle. 
Automatic Dialing-Station: Provides a pri- 
vate automatic dialing list of 40 numbers 
for each station in the system. The Flash 
and Pause functions may also be stored 
when necessary. 
%utomatic Off-Hook Selection: Allows CO 
line, CO group or intercom access by 
merely lifting the handset; depressing a 
CO/intercom key is not required. 
Busy Override: After calling, a busy station 
and receiving a busy tone, the caller can 
dial l and cause a tone burst to be 
sounded via the called EKT’s speaker. 
Call Forward: Allows all calls to a station to 
be routed to another station. The activating 
station may be used to originate calls 
while this feature is active. 
-12- Call Pickup: 
Enables a station to pick up 
calls ringing at other stations or an exter- 
nal page by going off-hook and dialing an 
access code. Call Pickup(m keys can be 
assigned to EKTs to automatically pick up 
calls. 
Call Transfer with Camp-on: Allows the 
transfer of an outside call to a station that 
is either idle or busy. 
/ - 
Directed Call Pickup: All calls ringing at an- 
other station can be answered from any 
station by that station going off-hook and 
dialing the ringing station’s number. 
Direct Station Selection 
(DSS) Keys: By 
depressing an assigned key, a station user 
causes the selected EKT to ring. A maxi- 
mum of two DSS keys may be assigned 
per EKT. 
Do Not Disturb: This feature is activated 
and deactivated by alternate depressions of 
the m key. A station calling a station 
that is in the DND mode will receive a 
fast busy tone. 
Do Not Disturb Override: After reaching a 
DND station, that station may be advised 
that a call is waiting by dialing 1. A tone 
signal will be heard at the DND station. 
DP/MF Mode Change (TONE) Key: Allows 
a station to than e between DP and MF 
modes via the 
l i& key, as required. 
Exclusive Hold: Depressing the m key 
twice holds that call securely for the sta- 
tion that placed it on hold. 
Executive Override (Break-In): A station 
programmed for this feature will override

the automatic privacy feature and enter 
any existing conversation within the sys- 
tem. A warning tone, however, is inserted 
before the overriding station is actually 
connected. After reaching a busy station, 
dial a 1 to override. 
Flash Key (PBX Transfer or CO Dial Tone 
Recall): 
EKTs can be equi ed with a 
Message Waiting/Flash 
(b key 
which, when operated while connected to 
a CO/PBX line, causes a timed “flash” to 
be transmitted to the CO or PBX. The tim- 
ing of the flash can be programmed to 
signal a PBX for feature operation or can 
be long enough to cause a disconnect and 
dial -tone recall on a CO line (not available 
on single-line 
EKT). Also see Message 
Waiting. 
Handsfree Answerback: All EKTs (except the 
single-line EKT) are equipped for handsfree 
answerback on voice-announced intercom 
calls as a standard feature. 
l-called Illumination: A distinctive flash ap- 
pears on the intercom LED at the EKT 
that is actually being called. 
l-hold Illumination: The EKT user is shown 
a distinctive LED flash to indicate a line 
placed on hold at the EKT. Other stations 
see a normal on-hold flash. 
l-use Illumination: A distinctive flash rate 
shows the line presently in use at a given 
EKT. Other stations see a steadily illumi- 
nated LED for that line. 
Modular Handset and Line Cords: All EKTs 
are equipped with modular handset and 
line cords, and (except for the single-line 
EKT) are also equipped with an additional 
modular headset jack. 
On-Hook Dialing: The system allows you to 
dial your calls with the handset still on- 
hook. Call progress can be heard via the 
telephone speaker;. no need to pick up the 
handset until your party answers. 
Push-Button Dialing: All EKTs are equipped 
with push-button dial pads. 
Repeat Last Number Dialed: The 
last 
numbet dialed by each station is always stored by the system and will .be dialed 
automatically whenever the station user 
accesses a CO line and depresses the B 
or m key. 
Ringing Line Preference: A line ringing a 
station can be answered b 
lifting the 
handset or depressing the 
’ . key. The 
&I 
ringing line will be automatically selected. 
Saved Number Redial: A programmable key 
that saves a dialed number for redial at a 
later time. May be used at any time and 
is exclusive of the Repeat Last Number. 
Dialed feature. 
Station Security (MC0 Key): Allows each 
station to individually enable or disable the 
Handsfree Answerback feature. 
Station-to-Station Message Waiting with 
LCD: 
An EKT’s station number may be 
sent to another station, indicating that the 
displayed station has called. See 20-key 
Liquid Crystal Display EKT. 
Trunk Queuing: Provides a means for station 
users to be “stacked” in a waiting queue 
for a .busy outgoing trunk group by using 
the Automatic Callback feature. The station 
will then be signalled when a trunk in the 
group becomes available. As a programma- 
ble option, the system may be equipped 
with one trunk group (dial 9) or four trunk 
groups (dial 91, 92, 93, 94). 
Optional Features 
Background Music with Station Control: 
Music from the music-on-hold source can 
(at the station user’s option) be heard via 
the EKT speaker. 
The same music may 
also be broadcast via the external page 
interface if an external speaker is installed. 
Door Phone/Monitor Station: Allows op- 
tional door phone unit(s) to distinctively 
ring pre-selected EKTs. EKT dialing to an 
individual door phone unit provides moni- 
toring capabilities on the intercom. 
l Alarm Key: Turns off the alarm signal 
set in the system by a customer-sup- 
plied alarm system. The alarm signal is 
activated by a closure at the HDCB 
door phone C output from a customer- 
supplied alarm system. The alarm signal

will be heard from all idle EKTs until 
the alarm key is depressed (station 10 
only). 
l Door Lock Key: Activates a dry contact 
relay closure for indirect control of a 
door lock or other devices. When the 
key is depressed, the HDCB door phone 
B output will close for a period of 3 or 
6 seconds. 
EKT Faceplates (Blue, Black or Wine): The 
standard brown faceplates can easily be 
changed on any EKT to coordinate with 
office decor. 
External Page Amplifier: This optional exter- 
nal page 3-watt amplifier (SEPU PCB) al- 
lows access to a customer-provided exter- 
nal 8-ohm speaker for paging. 
Music-On-Hold Source: When installed, this 
optional electronic music source (SMOU 
PCB) eliminates the need for a customer- 
provided external music source and pro- 
vides electronic-generated music to CO 
lines placed on hold. 
Off-Premises Extension: Installing an op- 
tional HOXB allows the system to interface 
with conventional, single-line telephones or 
off-premises circuits. The HOXB (one per 
system) serves two extensions and re- 
places two EKTs in the system. 
l MRGU: An auxiliary ringing/power 
supply for the HOXB. 
Off-Premises Line: Installing an optional 
HOLB allows the bridging of a CO/PBX 
line that appears in the system with a 
conventional telephone (or other device, 
such as a modem). During Night Service, 
all incoming calls on an HOLB’s three cir- 
cuits may be directed to an answering 
machine (or similar device) connected to a 
“hunting” output. This option is set in 
programming. 
Station Message Detail Recording (SMDR): 
Adding the optional HSMB allows data to 
be collected for each outgoing and incom- 
ing CO line call. This data is output to a 
printer or recording device 
via the 
RS-232C interface located on the HSMB. 
The HSMB is externally mounted. 
-14- System Battery Backup: 
An optional module 
(HPBU-7) can be installed in the power 
supply to provide automatic switching to 
standby battery power. During normal 
power conditions, the batteries are kept 
fully charged by the power supply.
