network. the telephone company may request the following:

1) Your telephone number.

2) FCC registration number:

l STRATA, may be configured as a Key or Hybrid

telephone system. The appropriate configuration for your system is dependent upon your operation of the system.

l If the operation of your system is only manual selection

of outgoing lines. it may be registered as a Key telephone system.

e If you operation requires automaiic selection of outgo-

ing lines: such as dial access. Least Cost Routing, Pooled Line Buttons. etc.. the system must be registered as a Hybrid telephone system. In addition to the

above. certain features (Off-premises Lines. Off-premises Extensions. etc.) may also required Hybrid telephone system registration in some areas.

’ ELECTRONIC KEY TELEPHONE SYSTEMS

1 GENERAL

Summary Description

STRATA Se and VI, are advanced electronic key telephone systems designed to function in a variety of situations. Both systems are electrically

- compatible with the public telephone network and can also be applied in a”behind” PBX. CENTREX. or IA2 environment.

Figure 1 shows all the basic electronic key system features, including CENTREX (CTX) capabilities and the impressive package of optional

features provided by these two systems. These features offer, among others, enhanced connectiv-

ity 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 COiCTX and/or PBX line.

Very similar in design, both systems are based on stored-program control, custom LSI circuitry, solid-state. space-division switching and reduced station cabling, and are housed in single cabinets.

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.

Depth: 2.75” (70 mmj

Weight: 15.63 Ibs. (7.1 kg)

System differences are restricted to the capacities of the key service units. STRATA Se has a maximum capacity of three incoming lines and eight stations, while STRATA VI, will accommodate up to six incoming lines with a maximum of 16 stations. Both systems have two intercom paths as a standard feature. with two additional paths available on the Vle as an optional feature.

Utilizing specially designed electronic telephones (each of which is connected to the system 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 3-pair cabling and modular cords must be used.

The optional door phone/monitor station (Figure 8) ailows distinctive ringing to preselected station(s). When a station dials an individual door phone, a circuit providing monitoring capabilities

on the intercom is established. This option requires station 13 and/or 14 (station I 1 and/or 12 in STRATA Se) to be replaced by a door phone control unit

(HDCB) and up to six door phone units (MDFBs)-

three each HDCB. One door phone/monitor (only station 13C for VI,; 11 C for S,) can be replaced by an alarm control circuit on starion 13/i 1 HDCB and

one by a door lock control circuit on ail HDCBs.

An external amplified speaker (HESB) may be connected in any one of the following three applications:

l

Loud Ringing Bell:

Allows you to amplify the

tone of a pagingiringing signal without using

other manufacturer’s equipment. Three-pair

wiring is required for this application. .

Amplified Speaker:

Allows you to use the HESB . as a paging speaker, reducing the need for other manufacturer’s paging equipment.

Taikback Amplified Speaker:

Allows you to

provide a talkback speaker in areas where a

telephone is not needed. For&alkback opera-

tion, connect the HESB to the door phone unit (MDFB), which is used as a microphone; however, the push-button is inoperative.

The HESB is a 6” 3-watt speaker with an

amplifier that is built into an attractive speaker box

(Figure 8). A +I2 VDC power supply (HACU-120),

which connects to the back panel via an 8’ cord. is

included with each HESB.

Installation

The key service unit is configured for wall

mounting only.

All external devices are connected to the key service unit via connectors and terminals on the side panels as follows: a) CO lines are connected to the key service unit

right side panel via separate (one for each line) single-pair modular cords or a single 3-pair modular cord (Se); or two 3-pair or six singlepair modular cords (Vle).

b) The station connection points are extended

from the key service unit to the main distribution frame using 3-pair modular line cords. The individual telephones are connected to the main distribution frame using 3-pair station cables.

c) A screw-terminal barrier strip is mounted on the

left-hand side of the key service unit to provide attachment points for the music-on-hold source input. relay service (Vie only) and external page

output).

d) Two (only one for Se) modular connectors are

also provided on the left side panel for two (only one for Se) optional off-premises line moduies

(HOLBs).

The power supply is mounted inside the key service unit. In STRATA Se a connector is provided on the left side panel for optional system reserve power (HPFB). In STRATA VI, an optional battery

backup printed circuit board is available for the power supply.

Maintenance

Faults in the system are repaired by replac-

ing any faulty component (printed circuit board, subassembly, telephone, etc.) and returning it to the manufacturer for repair.

In addition, remote administration/maintenance allows the system to interface via an SDTU (builtin modem) with a remote location. This reduces the cost of routine data base changes by eliminating

the need of a technician to be on-site for each

software change.
