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

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

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.
Multiple Trunk Groups:
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.

A keyboard/printer terminal (Texas
Instruments Model

or equivalent) is
required to communicate with the PERCEPTION
system. (See Section 100-I 00-300, Programming,
for operating details.)
The terminal is connected to the system
’
via a female-type RS 232C connector (labeled
TTY) located on the connector panel on the
lower rear of the DCEC.
In addition to the TTY connector,
DEM connector is provided. By attaching
a customer-provided “answer only” modem,
all functions normally performed by the local
terminal can be performed from a remote location.

An optional handsetanger kit is required to convert either typef EKT for wall
mounting. The EKT may be mounted on a wall
or any other flat, vertical surface to which the
base can be secured.

When selecting the mounting site, consider the EKT weight and the additional stresses
to which the mounting will be subjected.

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.
Route the tail cord through the holes

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.

12.25If 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.
39),
the
12.2All paging connections are made via
J13 in the DCEC connector panel. See Table N
for details.

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.
12.32A 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.
12.3Adjust the MOH volume with the MOW
volume control on the front of the DPMU PCB.
Maximum volume is limited by internal circuits
in order to comply with FCC regulations.

The Universal Night Answer
(UNA)
feature provides an output of interrupted ringing
voltage (85 f ‘IO VRMS, 20 Hz superimposed on
-24 VDC) whenever the system is in NITE service
and an incoming call is received by a trunk designated for UNA. Any station user, upon hearing
the chime or bell, can dial the UNA access code
and be connected to the caller.
