GENERAL DESCRIPTION 
NOVEMBER 1987 
01 GENERAL 
Summary Description 
STRATA Se and Vle are advanced elec- 
tronic key telephone systems designed to func- 
tion 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) capa- 
bilities, and the impressive packaae of optional features offer, among others, enhanced connec- 
tivity with stand-alone voice mail products, off- 
hook 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 cir- 
cuitry, solid-state, space-division switching and 
reduced station cabling, and are housed in sin- 
features provided by these two s{stems.‘These gle cabinets.

GENERAL DESCRIPTION 
NOVEMBER 1987 
System differences are restricted to the ca- 
pacities of the key service units. STRATA Se has 
a maximum capacity of three incoming lines and 
eight stations, while STRATA Vle will accommo- 
date 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 fea- 
ture. 
Utilizing specially designed electronic tele- 
phones (each of which is connected to the sys- 
tem via industry-standard 2- 
or 3-pair cabling 
and equipped with a push-button dial pad), solid- 
state 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. 
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. 
02 PHYSICAL DESCRIPTIONS 
Key Service Units

The STRATA Vle key service unit (Figure 4) 
is factory-equipped with two printed circuit 
boards (PCBs) and a power supply. The main 
PCB (VMAU) and power supply are secured to 
the cabinet base; the processor PCB (VCCU) is 
attached to the VMAU with four screws, and is 
connected to it via four lo-pin connectors.

Peripheral Equipment 
Several optional expansion modules are 
available to accommodate additional STRATAe 
ieait rres: Station Message Detail Recording 
(HSMB), lA2 Interface (HCNB), Auxiliary Device 
Interface (HIOB), Off-Premises Line (HOLB) and 
Off-Premises Extension (HOXB). The two pairs 
of modules are identical in external appearance 
(Figure 5). 
An HDCB that is needed to support up to 
three door phones (Figure 6) is available, with 
two per system being the maximum. An ex- 
ternal ring generator/power supply (MRGU) that 
can be used with the HOXB is also available (Fig- 
ure 7). An external amplified speaker (HESB) 
can either be used to amplify the ringing bell 
of a telephone or as a paging speaker (Figure 
8). When used in conjunction with the door 
phone unit, the HESB provides a talkback paging 
speaker capability.

03 ELECTRICAL CHARACTERISTICS 
General 
The key service unit operates from an inter- 
nal power supply, which connects to a standard 
3-wire, 117 VAC, 60-Hz, grounded wall outlet. 
Loss of AC power will cause operational fail- 
ure 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 approx- 
imately 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 elec- 
tronic key telephone systems are summarized in 
Tables 6 and C, which list the standard and op- 
tional features, respectively.

system. The integrated 
installed in blace of the ; for every station in the 
modem unit (HMDB) is 
standard electronic tele- 
phone base, and includes an RS232 connector 
for a personal computer or other data device. 
Each integrated modem unit will reduce the sta- 
tion capacity by one. 
System software assignments permit a 
wide variation to the feature buttons on all tele- 
phones. 
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.
