GENERAL DESCRIPTION

~o~f,~~,uration

---m-e-

The Model 616B and 616 electronic key systems consist of an electronic Key Service Unit (KSU),

dedicated electronic key system telephone sets (stations), and interconnecting wiring consisting of small, 4-wire, twisted-pair cable.

This electronic key system is designed to not only provide the

economy and features of a conventional "lA2 type" system but also a much easier installation made possible with small size wiring.

Advanced operating features are made possible by the electronic

technology used in the KSU and the dedicated key system telephone set. The system is equipped for a maximum of 6 lines and 16

stations.

Introduction

IMI 66-037

yo+e,l, Variations

-------I--

The Model 616 key system unit has been produced in two versions. The currently produced version is designated as 616B KSU.

It is an enhanced unit which provides standard key system features, adds station pin upward compatibility for growth, and includes

advanced operating features such as expanded toll restriction and class of service printout data.

The earlier produced version is designated as 616 KSU and is currently available only as a service replacement. Specifically, the 616B provides the

following operation enhancements: serial data printer port for

class of service printout; all-call and zone paging through all

system stations; three intercom links; and programmable toll restriction tables.

KSU Descriptipn

--- ------ ----

The KSU is a fully electronic key service unit. It is

essentially a special purpose computer system acting as a

communications controller between TELCO or PABX supplied lines

and proprietary 3-line and 8-line telephone stations.

The KSU is contained in a functional,

modern-style metal housing

of contemporary design in keeping with the needs of the modern office enviroment. It is engineered to be wall or rack mounted.

Telephone Set Descriptiqn

-'--- w--- m-- ---m-m s-s-

The telephone set is an electronic, device:

It is designed to allow not only multiline pickup but

also single button access to features available from the TELCO or PABX switch.

All stations are equipped with standard

microprocessor-controlled

serving

modular jacks.

The telephone sets are available in 3-line (s-button) and 8-line

(lo-button) handsfree dialing models; 3-line and 8-line full

speakerphone models: and an 8-line,

handsfree model with a busy

lamp field. KEY SYSTEM FEATJJRES The

electronic key telephone system provides a broad range of

features. Some of the features are a permanent part of the

system while others are programmable as part of the system or station programming procedure. The following paragraphs describe

the features.

Access Denied (Private Lines)

------- --MN'-- ----ova--.- ---we-

Access to particular lines can be denied to certain stations in

the system through system programming.

can be accomplished by pressing that line select key on their station.

An automatic redial of the last dialed number is available at

every station.

A busy number or unanswered call is automatically redialed by this feature. Once automatic redial is selected, the station will select a line,

automatically dial a number, and wait

for a response. It will do this once a minute for approximately

10 minutes. The user must lift the handset to complete the call voice link.

Lifting the handset or pressing any other key will cancel further automatic redial action. Users of the optional speakerphone

station can complete the call voice link by pressing the MONITOR OFF key instead of lifting the handset.

The system will detect an A-lead contact closure on certain

incoming lines. When the system detects an A-lead contact closure by an external device connected to one of these lines, it causes a busy line light indication for this line to

The system does not send any

A-lead signal to the external device connected to the line. Pressing the line select key on a system station cannot interrupt

an external device providing the A-lead closure unless the line

is programmed to be non-private.

The system provides basic, lA2 type features.

Features such as

selective line pickup, common line, hold, and multiline pickup and hold are available at every station.

Introduction IMI 66-037

The system programming is electronically protected during an

AC

power failure by a battery-like device called a "super-cap". stored program data will remain in memory for a minimum of 30

hours after AC power fails or is disconnected.

The system must

be powered continuously for at least 30 minutes prior to the

power failure or disconnection for memory preservation to occtir.

The internal speaker at each station provides call-announce capability over the intercom link.

A handsfree response to a

call-announce call can be made. This response is transmitted by

the microphone built into the handset.

Call Transfer

'- i - - 'A - - - i - 'i -

The

Call transfer allows incoming calls to be transferred from one

station to another,

via the intercom link, in one of two ways.

If both stations have access to the incoming line, a common line

pickup transfer can be effected.

If the other station does not

have access to the incoming line, transfer can still take place

using the system transfer feature.

Some transfer considerations

are as follows: If a transfer is attempted when there is no call

on hold, the station being transferred to will receive the

intercom dial tone, and the transferring station will he dropped from the intercom line. If a transfer is attempted and the

station being transferred to does not answer the intercom call,

the transferring station will reconnect to the call.

each station and line through COS programming.

When a line selection is made and a station is dialed, the system

examines the dialed number and makes a comparison between the station toll restriction tables and the line toll restriction tables. Any tables assigned to BOTH the station being used and the selected line determine the toll restrictions to be imposed.

Dialing a restricted number on a restricted line from a

restricted station will cause the line to be automatically disconnected for 2 seconds.

surface. It may be vertically rack mounted if desired. It

must be located within 6 feet of a properly grounded, three-wire,

117VAC, electrical outlet. The distance between the KSU and the TELCO/PBX jacks must be 25 feet or less as per FCC requirements. A nominal distance of 7 feet is recommended.

degrees F (O-49 degrees C). If the mounting surface is damp or

if it is concrete or masonry material, a backboard must be attached to the mounting surface to be used for KSU mounting. Suitable mounting backboards are available commercially or can be

constructed out of l/2-inch plywood cut to size. Tools and hardware required for mounting the KSU cabinet include:

l/4 x l-inch round head wood screws, toggle bolts, or wall

anchors and fasteners: a screwdriver: an electric drill if prepared holes are required;

and a connecting tool for fastening

wires to a type-66 connector block.

1.

A full scale mounting template is supplied in the KSU packing

box. Hold or tape this template to the mounting surface, and

mark the location of the mounting holes on the mounting

surface as they are located on the template. The KSU

mounting dimensions are as shown on Figure 1.

2.

Drill holes in the mounting surface of a proper size to accommodate the hardware being used.

If necessary, prepare

these holes with inserts, anchors or other attachment devices

as dictated by the type of mounting surface.

3.

Attach the KSU to the mounting surface with four (4) screws

do not connect the voice circuits to the data circuits. Doing so will make a pair of stations inoperative.

To apply AC power to the KSU,

properly grounded, three-wire, 117VAC electrical outlet. A

plug-in, power line surge protector should be installed between

the KSU power cord and the AC outlet. Many different models of surge protectors are commercially available for this purpose. _

It is recommended that a grounding wire,

wire AC line cord, be used. Some local codes may require this

use. A ground stud is located at the lower right corner of the KSU for this purpose. Wire a #lO or #12, insulated, solid copper

wire between this ground stud and a reliable earth ground such as

a metal cold water pipe or a building frame ground.
