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

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:

A keyboard/printer terminal (Texas
Instruments Model
743/745
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.

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

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

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.

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.
12.32 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.
12.3 Adjust 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.

Operating System programs and Customer Data are loaded into DRAM from
the diskette under the control of the Loader program,
