Toshiba Perception Electronic Business Communications System Installation And Maintenance Manual

							Night Service-Universal:
Trunks not otherwise assigned by Fixed or
Flexible Night Service will ring a common
bell or chime to indicate an incoming call.
Any station can answer the call by dialing aspecific access code.Remote Access to Services:
Allows a user outside the system to 
accethe system services via an exchange network
connection. The user dials a preselected DDD
number to connect to the system and then
dials a 3-digit authorization code. The user
may then make any call as if the user were
a system station. This service is provided only
when signalling is on a DTMF basis.
Remote Administration/Maintenance:
System will interface with a standard modem
to allow administration and diagnostic soft-
ware routines to be accessed from a software
location.
Rotary Dial Compatibility:
The system is compatible with conventional
rotary dial telephones.
Route Advance:
Routes outgoing calls over alternate facilitiesThe 
fdlowing station features are available
when the first trunk choice is busy.with either conventional telephones or 
EKTs.

TIE Trunks:
TIE Trunk 
PCBs are available to allow con-
nections to other 
PBXs.Toll 
Restriction:Stations may be restricted from making toll
calls. The system detects toll calls by recog-
nizing “0” or “1” dialed as the first or second
digit following the trunk access code.
*Future FeatureTone Dialing:
When equipped with DTMF receivers 
(DRCU
PCS), PERCEPTION is compatible with 2500
telephones.
Tone-to-dial Pulse Conversion:
DTMF signals from 2500 telephones are
automatically converted to rotary dial pulses
for transmission to a rotary dial central office.
Traffic Measurement:
The system provides traffic information, such
as peg counts and usage, to a terminal or printer.
Uniform Distribution Wiring:
Since PERCEPTION employs a 
d-wire elec-
tronic key telephone, conventional key equip-
ment is not required. It is possible, therefore,
to prewire an installation site with 
2 or 3-pair
cable without concern for the future configura-
tion of the system.
Variable Timeout:
The timeout intervals associated with most
features are variable by system programming.
Station Features:
A/O TE:Automatic Callback:
