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.

Mounting screws or mollies, appropriate

for the surface on which the telephone is to be

secured, must be provided by the installer.

Locking tabs secure the base to the

EKT. The direction in which the base is attached

to the EKT determines whether it will be used

as a desk unit or wall unit (it is factory-configured as a desk unit). Disengage the locking tabs by pushing downward on the base (Figure

Secure the base to the desired wall site. Use a spirit level and make certain the top of the base is level and that the deeper portion

is down.

must be equipped with a grounding push-button switch if the station is to make outgoing calls during a power failure.

A transfer can be caused by a loss of power or triggered manually by either of two buttons, one of which is located on the under-

side of the attendant console and the other is on the front of the DPMU PCB. A transfer that is caused by a power failure will be reset automatically when power is restored; a manual transfer

must be reset manually,

When the DPFT is reset after a transfer,

existing conversations will be protected. Individual circuits will be restored only when they become

idle.

By combining a single customer-supplied paging amplifier with the PERCEPTION paging interface and speaker zone switching, it is possible

to provide a paging system of up to five zones

with All Page capability.

12.22

Figures 39 & 40 show possible paging

arrangements. As a standard feature (part of the

DPMU PCB), the system provides a 600-ohm output to a paging amplifier. If more than one paging zone is required, the output of the amplifier can be routed back to the DPMU PCB where

it will be switched to one of five sets of speakers via relays Kl through K5. The relay to be operated

is determined by the access code dialed by the station user. The actual access code is assigned

in software (see Section 100-100-300, Program-

ming).

12.23

An All Page code can also be defined

in software. When that code is dialed, all relays will be activated simultaneously to permit paging to all speaker zones.

12.24

If the power loads of the different

zones are such that a single amplifier is not suitable,

multiple amplifiers (up to one for each zone) can be connected as shown in Figure 41.

12.25 If background music is to be used on

the paging system, two arrangements are possible:

‘I)

If the music is supplied from a separate ampli-

fier (as in Figures 40 &

41),

it can be con-

nected between the speaker common line and the PG GND input to the DPMU (J13 pin

#2).

Through the

Kl%

K5 relay “break” contacts, the music will be connected to all speaker zones when no page is in progress.

When a page access code is dialed, the proper

ZONE 5

~

relay operates, the music is disconnected

from that zone, and the page amplifier out-

put is connected.

2)

If the music is connected to a second input of

the paging amplifier (as in Figure

PG 1 control lead (J13 pin

#27)

can be connected to the MUTE terminal of the page amplifier music channel. When any page access code is dialed, a ground output is applied to the

PGI

lead to mute the music.

A Music-on-hold

(MOH)

interface is a

standard PERCEPTION feature. The circuitry occupies part of the DPMU PCB. When MOH is equipped it will be heard by any station or trunks on-hold in the system, or by any trunk put into the camp-on state.

12.32 A tuner or other program source must be provided by the customer. The program source is connected to the MOH input via pins #4 and

#29

(Br-W and W-Br) of

J13

(see Table N). The

input impedance is 600 ohms.

Operating System programs and Customer Data are loaded into DRAM from

the diskette under the control of the Loader program,
