01 GENERAL
Summary Description
STRATA Se and Vle are advanced electronic key telephone systems designed to function in a variety of situations. Both systems are
electrically compatible with the public telephone
network and can also be applied in a “behind
PBX” environment.
Figure 1 shows all the basic electronic key
system features, including CENTREX (CTX) capabilities, and the impressive packaae of optional
features provided by these two s{stems.‘These gle cabinets.
features offer, among others, enhanced connectivity with stand-alone voice mail products, offhook call announce (OCA), SMDR, remote
administration/maintenance, and 32-character
alphanumeric Liquid Crystal Display read-outs.
Wherever a CO line interface is indicated in the
following text, it can be a CO/CTX and/or PBX
line.
Very similar in design, both systems are
based on stored-program control, custom LSI circuitry, solid-state, space-division switching and
reduced station cabling, and are housed in sin-

GENERAL DESCRIPTION
NOVEMBER 1987
System differences are restricted to the capacities of the key service units. STRATA Se has
a maximum capacity of three incoming lines and
eight stations, while STRATA Vle will accommodate up to six incoming lines with a maximum
of 16 stations. Bath systems have two intercom
paths as a standard feature, with two additional
paths available on the Vle as an optional feature.
Utilizing specially designed electronic telephones (each of which is connected to the system via industry-standard 2and equipped with a push-button dial pad), solidstate electronics within the key service unit
translate signals from the station dial pad into
either DTMF or rotary-dial signals, as required
by the Central Office. If the system is to be
equipped with off-hook call announce and/or
modem phones (see Station Equipment), 3-pair
cabling and modular cords must be used.
or

Maintenance
Maintenance - procedures are based on
quickly locating and replacing defective plug-in
units, keeping service disruption to a minimum.
In addition, remote administration/maintenance
is also an available option for both systems.

03 ELECTRICAL CHARACTERISTICS
General
The key service unit operates from an internal power supply, which connects to a standard
3-wire, 117 VAC, 60-Hz, grounded wall outlet.
Loss of AC power will cause operational failure of the system. System memory, however, is
protected from loss due to power failure with a
memory backup battery. Full system reserve
power is available as an option.
NOTE.
The memory backup battery is designed to
maintain full memory protection for approximately one year with no external power
source applied.
The electrical characteristics of the system
are summarized in Table A.
04 FEATURES and SERVICES
The features and services of these electronic key telephone systems are summarized in
Tables 6 and C, which list the standard and optional features, respectively.
Each electronic telephone features a modu-
lar handset cord, a modular headset/audio-type
device (headset I/O switch) connector (except
the single-line) and is connected to the system
via a 2-pair modular line cord. If a modem, off-
hook call announce, or HESB as a Loud Ringing
Bell is to be used, 3-pair cabling must be used.

05 SYSTEM OPERATION
General
A system (Figure 15) consists of a key service unit (Vie HKSU is shown), power supply, up
to 16 stations*, HOLB, HSMB and HOXB optional modules, and a maximum of six door
phones, The door phone control unit(s) (HDCB)
occupy one or two station location(s). All connec-
rinrs ber\/lleen the key service unit and the tele-
phones are made via a customer-provided main
distribution frame. Using modular line cord(s),
the CO lines are then connected between the
-left side panel and the locally provided RJ-25C
(up to two each) or RJ-11C (up to six each)
jacks. An external tuner (or equivalent) is re-
quired if the Music-On-Hold/Background Music
feature is utilized.
*Some optional features reduce maximum
station capacities (see Optional Features).
A functional block diagram of both key service units is shown in Figure 16. It consists of
CO and station interfaces on the main PCB, including a solid-state, space-division matrix and
the central control equipment (SCCU/VCCU). Op-
tional interfacing equipment includes additional
station connections (SSTU), off-hook call an-
nounce (SVCU), remote maintenance (SDTU), offpremises line (HOLB), station message detail
record (HSMB/STMU*), lA2 interface (HCNB),
auxiliary device interface (HIOB), door phone controller (HDCB) and door phone/monitor station,
external page amplifier (SEPU), internal musicon-hold source (SMOU), and power failure
(SPFU”) PCBs are a!so shov.n.
“STRA TA Se only
The system is entirely under the control of
a single-chip microprocessor, located (along
with the system program and data memories) on
the VCCU/SCCU PCB (STRATA Vie/Se, respectively), which mounts on the VMAU/SMAU, respectively.
Connections between the station voice lines
and the CO lines are via the switching matrix
provided on the VMAULSMAU PCB (STRATA
We/Se, respectively). The VMAUSMAU also
provides a similar matrix for intercom connection, background music, paging connections and
the distribution of various system tones (dial,
busy, etc.).

HIOB: Provides one circuit to interface with ex-
ternal devices such as a voice mail port, an-
swering machine, standard telephone, mo-
dem, etc. Up to eight HlOBs (four on a
STRATA Se) may be installed on a system.
Each HI06 is connected to a proprietary sta-
tion port, reducing station capacity accord-
ingly.
Station Equipment
The principal components of the electronic
telephone are: handset, dial pad, speaker, microphone, two volume controls, four fixed feature
buttons, an m button, and 9 or 19 flexible CO/
feature buttons. LED indicators are provided for
all buttons except for m and m. See Fig-
ures 10 and 12.
The single-line electronic telephone (Figure
9) is equipped with three permanently dedicated
buttons (mm=) and an Intercom/CO
line button, which is not labeled.
The lo-button Busy Lamp Field electronic
telephone (Figure 11) with speakerphone provides 10 buttons that can be assigned to control
intercom, CO line and feature operation, plus an
LED indication of which stations are in use.
A 20-button Liquid Crystal Display electronic telephone (Figure 13) with speakerphone
may be located at any or all of the stations. The
32-character alphanumeric display provides
many capabilities- an accurate clock/calendar
in its idle state; and elapsed time, dialed
number, calling station and CO line are just a
few of the features available. For additional explanations of the features listed below, see Liquid Crystal Display.

All phones are easily converted for wall
mounting, feature modular handset cords, are
equipped with a second modular connector for
headset connection (except the single-line), and
are connected to the system via modular line
cords.
An optional replacement base for the electronic telephone provides a built-in 300/1200
baud modem with automatic answering capabil-
ities. It is a Bell Standard, full duplex modem.
The optional door phone/monitor station
(Figure 6) allows distinctive ringing to preselected station(s). When a station dials an individual door phone, a circuit providing monitoring
capabilities on the intercom, is established. This
option requires station 13 and/or 14 (station 1 1
and/or 12 in STRATA Se) to be replaced by a
door phone control unit (HDCB) and up to six
door phone units (MDFBs)-three each HDCB.
One door phone/monitor (only station 13C for
Vle; 11 C for Se) can be replaced by an alarm
control circuit on station 13 HDCB and one by
a door lock control circuit on all HDCBs.
An external amplified speaker (HESB) may
be connected in any one of the following three
applications:
l
Loud Ringing Bell: Allows you to amplify
the tone of a paging/ringing signal without
using other manufacturers’ equipment. The
signal can be amplified on all 6000-series
phones, except the single-line electronic telephone. Three-pair wiring is required for this
application.
l
Amplified Speaker: Allows you to use the
HESB as a paging speaker, reducing the
need for other manufacturers’ paging equip:
ment.
l
Talkback Amplified Speaker: Allows you to
provide a talkback speaker in areas where a
telephone is not needed. For talkback operation, connect the HESB to the door phone
unit (MDFB), which is used as a microphone;
however, the push-button is inoperative.
The HESB is a 6” 3-watt speaker with an
amplifier that is built into an attractive speaker
box (Figure 8). A +12 VDC power supply
(HACU-120), which connects to the back panel
via an 8’ cord, is included with each HESB.
Installation
The key service unit is configured for wall
mounting only.
All external devices are connected to the
key service unit via connectors and terminals on
the side panels, as follows:
a) CO lines are connected to the key service
unit right side panel via separate (one for

each line) single-pair modular cords or a
single 3-pair modular cord (STRATA Se); or
two 3-pair or six single-pair modular cords
(STRATA Vie).
b) The station connection points are extended
from the key service unit to the main distribution frame using 3-pair modular line cords.
The individual telephones are connected to
the main distribution frame using 3-pair station cables.
c) A screw-terminal barrier strip is mounted on
the left-hand side of the key service unit to
provide attachment points for the music-onhold source input, relay service (STRATA Vle
only) and external page output.
d) Two (only one for STRATA Se) modular con-
nectors are also provided on the left side
panel for two (only one for STRATA Se) op-
tional off-premises line modules (HOLBs).
The power supply is mounted inside the key
service unit. In STRATA Se a connector is provided on the left side panel for optional system
reserve power (HPFB). In STRATA Vle an op-
tional battery backup printed circuit board is
available for the power supply.
Maintenance
Faults in the system are repaired by replac-
ing any faulty component (printed circuit board,
subassembly, telephone, etc.) and returning it to
the manufacturer for repair.
In addition, remote administration/
maintena-rice allows the system to interface via
an SDTU (built-in modem) with a remote loca-
tion. This reduces the cost of routine data base
changes by eiiminaring the need of a technician
to be ?n-site for each software change.
07 FEATURES and OPERATION

numbers to be stored in the system memory.
After selecting an outgoing line, any station
user can cause one of the.‘stored numbers to
be outpulsed by dialing the proper access
code.
Automatic Hold Recall: A CO line placed on
hold by any station will recall that station af-
ter a programmable period of time. A different
time period can be selected fo: each station.
Automatic Release from Hold: The system au-
tomatically releases held CO lines if a discon-
nect signal is r,eceived from the Central Of-
fice.
CO Line Pickup Groups: In STRATA Vle only,
using a dial code or the m button, allows
CO line pickup from another station. Two Call
Pickup Groups can be defined in programming and buttons (m and m) can be as-
signed to phones for each group.
Conference (Multi-CO Line): The system will
conference two CO lines and up to three sta-
tions. See Amplified Conference.
Conference(Multi-Station): Non-amplifiedcon-
ferencing is permitted to a maximum of four
stations and one CO line. See Amplified Conference.
CTX/PBX Compatible: System features, such
as Toll Restriction and Automatic Dialing, are
compatible with CTX/PBX operation.
CTX Ringing Repeat: To facilitate the use of
special calling/callback features on CO/CTX/
PBX lines, the system will ring the called station with the same on/off cadence that is received from the outside line.

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 connec-
tion point is provided for a customer-provided
external amplifier/speaker. An SEPU PCB
(see External Amplified Speaker and External
Page Amplifier) is mounted in the key service
unit when a customer-provided external
speaker only is used; the output impedance
is 8 ohms. This page circuit can be accessed
as part of the All Call Voice Page feature.
F!exible Intercom Numbering: A station inter-
com number can be flexibly programmed up
to any 4-digit number. It is, therefore, possible
to match a station’s intercom and CTX line extension number.
Flexible Key Assignment: Allows each phone
to be programmed for the optimum use of its
CO or feature buttons.
Flexible Line Ringing Assignment: A program-
mable ring or no ring option is provided for
each line selectively by each station.
Forced Account Code: Requires selected sta-
tion(s) to dial an account code prior to dialing
a number. The account code is recorded with
call details on the SMDR report.
Message Waiting: Any station (including the
designated Message Center) can set a Mes-
sage Waiting LED at any station with the Message Waiting LED of that station. The called
station cancels the LED by lifting the handset
and depressing the m button (not available on single-line electronic telephone). See
Flash Button.
MF Signal Time (160/80 ms): The standard
MF dial signal time is 80 milliseconds, but it
may be extended to 160 milliseconds, if re-
quired by the Central Office or to activate re-
mote equipment.
Multiple Simultaneous Handsfree Intercom
Paths: Two intercom paths are standard in
the systems. Both intercom lines are able to
carry handsfree conversations simultaneously. (STRATA Vle may be increased to four
paths optionally.)
Music-On-Hold Interface: An interface is in-
cluded 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 electronic telephone speakers and external page when the background
music programming options are selected.
Night Ringing Answer Code: A night ringing
call may be answered from any station via a.
dial code.
Group Paging: Special 2-digit access codes
(81, 82, 83 or 84) permit voice paging to one
of four zones. Zone assignment is via $oftware and is totally flexible. Paging is via the
speakers of idle telephones.
Least Cost Routing: Enables the customer to
decide over which trunks outgoing voice and
data calls will be routed. This can greatly reduce the cost of long distance calling. Four
classes of LCR can be programmed to give
priority routes to .the users who need them.

handsfree, the caller will receive a busy sig-
nal. Feature is activated automatically or by
dial access (I) on a station-by-station basis.
Off-Premises Extension:
Installing an HOXB al-
lows the system to interface with conventional, standard telephones or off-premises circuits. The HOXB serves two extensions and
replaces two stations in the system. (Maximum: two per STRATA Se/four per STRATA
Vie.)
l
MRGU:
An auxiliary ringing/power sup-
ply for the HOXB.
Off-Premises Line:
Installing an 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 circuits may be directed to an
answering machine (or similar device) con-
nected to a “hunting” output. This option is
set in programming.
Remote Administration/Maintenance:
The
SDTU provides this feature via its built-in
300/1200 baud modem. One SDTU per sys-
tem is required for Remote Administration/
Maintenance.
Station Message Detail. Recording (SMDR):
Adding an HSMB to a system allows data to
be collected for each outgoing and incoming
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.
System Battery Backup:
a) In STRATA Se, an HPFB can be plugged
into the HPSU to provide automatic switching to standby battery power.
During
normal power conditions. the batteries are
kept fully charged by the power suppiy.
The HPFB includes batteries and the charg-
ing unit:
b) In
STRATA Vie, an HPBU
can be installed
in the power supply to provide automatic
switching to standby battery power (provided by customer). During normal power
conditions, the batteries are kept fully
charged by the power supply.
