Toshiba Perception EKTS User Guide

The PERCEPTION electronic business communications system is registered in accordance with the provisions of Part 68 of the Federal Communications Commission’s Rules

Regulations.

The Federal Communications Commission (FCC) has established rules which permit the PERCEPTION electronic business communications system to be connected directly to the telephone network. Connection points are provided by the

telephone company-connections for this type of customer-provided equipment will not be pro-

vided on party lines or coin lines.

and

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

7~443-~F-~)

The ringer equivalence number

4.O(DC)

D. The USOC jack required

items B and C are also indicated on the equipment

label.

You must notify the telephone company upon

final disconnection of your equipment.

(RJ21X)

(BF287N-

1.2B(AC)/

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.

atibi

The 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.

Warning: -This equipment generates, uses, and

can radiate radio frequency energy and if not

installed and used in accordance with the instructions manual, may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC

Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this

equipment in a residential area is likely to cause

interference; in which case, the users, at his own

expense, will be required to take whatever measures may be required to correct the interference.

Toshiba Telecom reserves the right, without prior notice, to revise this information publication for any reason, including, but not limited to, utilization of new advances in the state of technical arts or to simply change the design of this document,

Further, Toshiba Telecom also reserves the right, without prior notice, to make such changes in equipment design or components as engineering or manufacturing methods may warrant.

This section contains a brief description

System Features:

Allows stations to access and use a

supplied amplifier for voice paging. The system provides five paging zones, which may be

accessed individually or all together.

Accesses a Common Control Switching Arrange-

ment (CCSA) network for network inward dialing to the system, direct outward dialing to the CCSA network, and other features similar to those provided on the public exchange

network.

The system provides 16 classes of service

which may be assigned to stations to allow

or deny access to features.

a toll call is detected by system analysis of the

first three digits dialed after the trunk access

code.

The system may be operated without a console,

all incoming trunk calls are handled using the Plight Service features.

PERCEPTION is suitable for voice-band data applications and is compatible with conven-

tional modems. ,

Distinctive Ringing:

Three types of ringing are provided to distinguish among station-to-station calls,

to-station calls and automatic callbacks.

Flexible Numbering:

Station directory numbers, as well as trunk

/ J,

and special service access codes, may be assigned

in accordance with the numbering plan desired

by the customer.

immediate Ringing:

Ringing occurs at a called station as soon as it is determined to be idle. There is no delay

caused by waiting for the ringing cycle.

Intercept:

Calls that cannot be completed because of system restrictions or dialing errors are intercepted and routed to either the attendant or to overflow tone depending on the type of call.

Line Lockout:

Stations that do not hang up at the end of a call, or that go off-hook and do not complete dialing within a predetermined length of time,

are released from the common equipment.

Multiple Console Operation:

Two attendant consoles,, may be used with

PERCEPTION.

PERCEPTION can accommodate up to 16

trunk groups.

Music-on-hold and Camp-on:

A standard interface allows connection to a

customer-provided music source. When music

is provided in the system, it is connected to all calls placed in the hold or camp-on condition by a station or the attendant.

Night Service-Fixed:

When the system is in the night service mode,

incoming trunk calls are routed to preselected

stations.

Night Service-Flexible:

Allows the attendant to assign trunks to stations for night service. During night service,

incoming calls on these trunks will be routed

to stations assigned by the attendant.

trunk-

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 a specific access code.

Remote Access to Services:

Allows a user outside the system to the 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 software routines to be accessed from a software

location.

Rotary Dial Compatibility:

The system is compatible with conventional

rotary dial 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 tronic key telephone, conventional key equipment is not required. It is possible, therefore, to prewire an installation site with 2 or 3-pair cable without concern for the future configuration of the system.

Variable Timeout:

The timeout intervals associated with most

features are variable by system programming.
