Toshiba Perception Electronic Business Communications System Installation And Maintenance Manual

							The PERCEPTION electronic business com-
munications system is registered in accordance
with the provisions of Part 68 of the FederalCommunicationsCommission’sRules
and
Regulations.The Federal Communications Commission
(FCC) has established rules which permit the
PERCEPTION electronic business communications

telephone company-connections for this type of
customer-provided equipment will not be pro-
vided on party lines or coin lines.If a PERCEPTION system is malfunctioning,
it may also be disrupting the telephone network.
The system should be disconnected until the
problem can be determined and repaired. If this
is not done, the telephone company may tem-
porarily disconnect service.
atibiThe telephone company may make changes
in its technical operations and procedures. If
such changes affect the compatibility or use of
a PERCEPTION system, the telephone company
is required to give adequate notice of the changes.Before connecting a PERCEPTION system to
the telephone network, the telephone company
must be provided with the following:A. Your telephone number
. The FCC registration number 
(BF287N-
7~443-~F-~)
C. The ringer equivalence number 1.2B(AC)/
4.O(DC)D. The USOC jack required 
(RJ21X)
items B and C are also indicated on the equipment
label.You must notify the telephone company upon
final disconnection of your equipment.Warning: -This equipment generates, uses, and
can radiate radio frequency energy and if not
installed and used in accordance with the instruc-
tions manual, may cause interference to radio
communications. It has been tested and found
to comply with the limits for a Class A computing

							0Summary Dew-i01.01PERCEPTION is an advanced business
communication system, employing stored programcontrol,digital switching,
and custom LSI
circuitry.
1.02Utilizing the same electronic key tele-hone as the new Toshiba STRATA electronic
key telephone systems (EKTS), PERCEPTION
combines the functions of conventional electronic
private branch exchange (EPABX) systems and
electronic key telephone systems into a single
design while remaining compatible with existing
switching and station equipment.
3PERCEPTION has a capacity of 120
stations and 32 trunks. The system provides a
wide variety of basic and optional features to
users of conventional rotary dial or touchtone
telephones, as well as to users of Electronic Key
Telephones.Two different Electronic Key 
Tele-s 
(EKTs) are available with PERCEPTION.
Each is equipped with a push-button dial pad,
speaker, four fixed feature keys (SPKR, MUTE,
CONF and HOLD) and either 
10 or 20 flexible
assignment keys (hence the names 
IO-key and
20-key). Of the four fixed keys, only the 
jkey is equipped with an LED. Both 
EKTs feature
modular handset cords and are connected to the
system via four-conductor modular line cords.
The basic PERCEPTION EKT is a IO-key,
with 
10 keys that may be assigned as directory
number (DN) pickups or as access keys to any
of the station custom calling features.-The expanded 20-key EKT has an additional
10 flexible assignment keys that may be
assigned as DN pickups or feature access keys.The PERCEPTION Attendant Console
th attractive and efficient. Its digital display
provides the operator with all the information
required for easy operation. Two attendant con-
soles may be equipped in the system.Housed in a single attractively styled
cabinet, the noiseless operation, small size and
environmental tolerance of the central equipment
allows a wide choice of installation locations.01.10
Physical Description
1.11The physical parameters of the metal
PERCEPTION equipment cabinet (Figure 
1) are:
Height39.25 in. (997 mm)
Width20.47 in. (520 mm)
Depth15.75 in. (400 mm)
It weighs 187.4 lb. (85 kg) when fully equipped.

The central equipment cabinet is divided
into four shelves (Figure 2); two shelves for plug-inprinted circuit board (PCB) mounting, one shelf
for the power supply, and the top shelf contains
the Floppy Disk/Ringer Assembly 
(DFRA).External connections are made to the
via amphenol-ended cables connected
at the rear of the cabinet (Figure 
3), and ter-
minated on a main distribution frame 
(MDF).
PCBs measure 12.01 inches (305 mm)
high by 12.01 inches (305 mm) deep, and each
one has a metal faceplate riveted to the front
edge. The rear edge connector carries the electricalterminals: 
60- and 40-pin terminals on the peri-
pheral equipment 
PCBs and loo-pin terminals
on the common equipment PCBs.

the left side of the DF RA subassembly.The 20 Hz ringing power supply 
(DRNG)is mounted on the right side of the DFRA sub-
assembly.1.17The primary power supply 
(DPSA)IS mounted in the bottom of the equipment
cabinet. It is operated by 115 VAC,

commercial power and provides a fused output
of -48 VDC, -24 VDC, 
*I2 VDC and k5 VDC.

only the 
‘SPI(R] key is equipped with an LED.Both 
EKTs feature modular handset cords and
