loading is complete.
e) When loading is complete, system will initialize
and clear all 
LEDs. Only a true fault indication
will remain. Refer to Section 100-100-500,
Fault Finding Procedures, for meaning of
indications and assistance with fault clearing.
f) Refer to Section 100-100-300, Programming,
to complete customer data assignments.
NOTE:
DlSP LED #7 and the console’s NIN LED
will be on until the system3 Date and Time
have been set via the console.
eneralAll connections to miscellaneous 
equip-are made via J13, TTY, Modem or SMDR
connectors on the connector panel of the DCEC.
NOTE:
The DATA connector is reserved for future

ai~~rel~~~~~ency Transfer
The function of the Power Failure/
mergency Transfer Unit (DPFT) is to automati-
cally connect selected trunks to selected conven-
tional telephones in the event of system failure
while permitting normal operation when the
system is in service.
The DPFT is a self-contained module
e37) that mounts externally to the DCEC,
typically on the MDF. Connections to the trunks,
stations and DCEC are made via two 50-pin
amphenol-type connectors 
(Jl and J2). A func-
tional diagram is shown in Figure 38.
3The module consists of eight relays that
are normally held operated, thus connecting the
telephones to the DSTU circuit and the trunks
to the DCOU circuits. Should a transfer occur,
the telephones bypass the DCEC equipment and
are connected directly to the trunks.
In systems where ground start trunksare used, each of the assigned station instruments
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
poweror 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 automati-
cally when power is restored; a manual transfer
must be reset manually,
6
When the DPFT is reset after a transfer,
existing conversations will be protected. Individual
circuits will be restored only when they become
idle.
12.17
The DPFT is installed as follows:
a)Mount the DPFT on the MDF.
b) Using 25-pair cables with amphenol-type
connectors (female for 
Jl, male for J2),connect the DPFT to two “66’‘-type 
quick-connect blocks.
c)Using Table R for a guide:
Connect the trunks selected for 
emer-
gency use to the Jl block “CO TIP” and
“CO RING” terminals.
Connect the DCOU circuits relating to the

d)Using Table S for a guide:

nated for emergency use, to the proper
terminals on the J2 block “TEL TIP”
and “TEL RING” terminals.

emergency telephones to the J2 block

2.21By 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 zoneswith 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 ampli-
fier 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 proper2)relay operates, the music is disconnected
from that zone, and the page amplifier out-
put is connected.
If the music is connected to a second input of
the paging amplifier (as in Figure 
39), the
PG 1 control lead (J13 pin 
#27) can be con-
nected 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. 
						

							12.2All paging connections are made via
J13 in the DCEC connector panel. See Table N
for details.112.31A 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.

12.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 desig-
nated for UNA. Any station user, upon hearing
the chime or bell, can dial the UNA access code
and be connected to the caller.
2The ringing voltage output is intended
ontrola strategically located chime or loud
ringing bell. The available power is five (5) ringer
equivalents.
Connections to the UNA ringing signal
are via pins 
#22 and #47 (O-V, V-O) of J13 (see
Table 
N) or J16 (see Table Q).2.5The PERCEPTION Station Message
Detail Recording 
(SMDR) feature allows a business
to analyze, and thusly control, its telephone costs.
Data can be collected for each outgoing and/or
incoming trunk call. Each such call generates a
call record which is available at the female type
RS232C connector (labeled SMDR) located on
the connector panel at the lower rear of the DCEC.12.52
j_The SMDR output can be connected to:
A local 
80-column printer for an on-line print-
out at the termination of each trunk call.
A recording device to store data for subse-
quent processing, either on-site or by a ser-
vice bureau.

							The data rate at the SMDR output may
ected as 300 or 1200 bps by operating the
SMDR push-on/push-off switch on the front panel
of the DPEU PCB. When the 1200 bps speed is
chosen, the LED will be lit.
1The code used by the SMDR is standard
7-level ASCII using one start bit, one stop bit and
one parity bit (even parity).
On an optional basis, it is possible to

“1When outgoing calls are chosen, all
calls seizing a trunk will be recorded’ regardless
of duration. On incoming calls, all answered
calls will be recorded. Calls disconnected by
Toll or Code Restriction features are not recorded.
Timing for recorded calls will start as
follows:
Outgoing-when trunk is seized
Incoming to attendant only-when attendant
answersIncoming and extended by the 
attendant-when attendant answers.
It is possible for the station users to
enter a Charge Account code of up to 
12 digits
into a call record.The recording criteria and Charge
Account code length are defined in the DMDR
Data Block Program (see Section 
100-100-300,Programming).
Each time a trunk is seized, information
is collectedfor that trunk until it is released.

							The format of the special records, Initialize/Reload
and Time Change is as follows:
Initialize/Reload:

00 (Initialize or Reload)
Any record printed after the initialize
record will appear on the same line and
be offset three colums from the usual
record.
Example:
NNNN (previous record)
00NNNNN (init. and next record)
