5. INSPECTION, PACKINGand STORAGE
5.00 Inspection
5.01 When the system is received, examine all
packages and make careful note of any visible
damage. If any damage is found, bring it to the
attentionofthedeliverycarrierandmaketheproper
claims.
5.02 Checkthesystemagainstthe purchaseorder
and packing slip. If it is determinedthat equipment
is missing, contact your supplier immediately.
5.03 After unpacking (and before installing), in-
spect all equipmentfor damage.Ifany isdetected,
contact your supplier immediately.
CAUTION!
When handling (installing, removing, ex-
amining,etc.)printedcircuit boards(PCBs),
do not touch the back (soldered) side or
edge connector. Always hold the PCBby
its edge whenever handling it.
5.10 Packing and Storage
5.11 When storingorshipping PCBs, besurethey
are packed in their original antistatic bags for pro-
tection against static discharge.
5.20 Required Tools
5.21 InstallationofthePERCEPTIONeLe,systems
requiresstandardtelephony tools. A 13mmsocket

avoid power degradation bysupplementing the -24
volts, maintaining a constant power level.
4. EXTENDED RESERVE POWER
4.00 The powersupply isequipped, asastandard
feature, with an internal battery chargemnverter.
Full reserve power can be provided for anysystem
by connecting an appropriate, customer-supplied
24-volt battery pack. During normal operation, the
power supply chargemnverter will maintain the
proper charge inthe battery pack. Inthe eventofan
AC power failure, switchover to battery power will
be automatic. There will be no loss of system
operation as a result of power switchover. When
AC power is restored, switchback to the power
supply will be automatic.
4.01 Battery selection and size will depend on
system size and desired reserve operating time.
The maximum power consumption of the basic
cabinet is 11.5 amps at -24 VDC. For both a basic
and expansion cabinet configuration, the maxi-
mum will be 19 amps at -24 VDC. The selected
batteries must be compatible with the system’s
charger float voltage of 27.3 VDC.

5. POWER FAILURE/EMERGENCY TRANSFER
5.00 Thefunction ofthe PowerFailure/Emergency
Transfer Unit (DPFT) is to automatically connect
selected trunks to selected standard telephones in
the event of system failure while permitting normal
operation when the system is inservice (maximum
of 1 per cabinet).
5.01 The DPFT is a self-contained module that
mounts externally to the basic cabinet, typically on
the MDF. Connections to the trunks, stations and
basic cabinet are made via two 50-pin amphenol-
type connectors (Jl and J2) on the DPFT (see
functional diagram in Figure 2-6).
5.02 The module consists of eight relays that are
normally operated, connecting the telephones to
NSTU circuits andthe trunks to NCOU circuits. Ifa
power failure (or other emergency) occurs, the
relays release, connecting the telephones directly
to the trunks. Calls can then be placed from the
telephones over the CO trunks, bypassing the
system (which is out of service).

netted to ground-start trunks must have ground
taps (tap buttons) in order to make outgoing calls
during powerfail transfer conditions.
5.04 A transfer can be caused by a loss of power
ortriggered manuallyby either of two buttons,one
of which is located on the underside of the atten-
dantconsoleandtheotheronthefrontoftheNPRU
PCB. A transfer that is caused by a power failure
will be resetautomaticallywhen power is restored;
a manualtransfer must be reset manually.
5.05 When the DPFT is reset after a transfer,
existing PFTconversationswill be protected. Indi-
vidual circuits will be restored only when they
become idle.
6. PRINTEDCIRCUITBOARDDESCRIPTION
6.00 Sixteen differenttypes of PCBs areavailable
for use in both PERCEPTIONsystems (Figures2-
7 & 2-8). The universal port architecture enables
multiple installation of trunk cards. The
PERCEPTlONe can support a maximum of 16
trunk cards; 8 in the basic cabinet, and 8 in the
expansion cabinet. The PERCEPTIONex can
support a maximum of 32 trunk cards; 24 in the
basic cabinet, and 8 in each expansion cabinet.

8. PERIPHERAL EQUIPMENT
8.00 Electronic and Digital Telephone
8.01 Fourdifferent electronic telephones and two
different digital telephones may be used in the
system.
8.02 All electronic telephones share the same
dimensions:
Height: 3.7 in. (94mm)
Width: 7.1 in. (180mm)
Depth: 9.5 in. (241mm)
8.03 All digital telephones share the same dimen-
sions: Height: 3.6 in. (92mm)
Width: 7.3 in. (184mm)
Depth: 9.0 in. (229mm)
8.04 Bothelectronicanddigitaltelephonesfeature
modular handsetcords. Electronictelephones are
connected to the system via 4-conductor modular
2-8

line cords. Digital telephones are connected to the
system via 2-conductor modular line cords. In ad-
dition,all models may beusedatany or allstations.
8.10 Headset Upgrade (HHEU)
8.11 Each electronic/digital telephone may also
be upgraded to provide a modular headset jack by
installing a headset upgrade assembly. The as-
sembly consists of a small PCB (HHEU) which
installs on the main PCB, inside the electronic or
digital telephone, with a plug-in connector. Most
standard headsets are compatible with the HHEU
jack.
8.20 Attendant Console
8.21 The Attendant Consoleisavailable with face-
plates for the Business and Lodging/Health Care
applications. The console consists of a plastic
housing with handset/headset modular jacks. Two
horizontal rows of non-locking buttons, LEDs and
a 12-button dialpad enable call processing.
8.30 DSSConsole
8.31 As an option both electronicand digital Direct
Station Selection (DSS) consoles can be usedwith
systems that do not require attendant consoles, or
requiredistributed call-handlingpositions.Two DSS
consoles per electronic/digital telephone, up to a
system maximum of eight DSS consoles, can be
installed.
8.40 Standard Telephone
8.41 Standard telephones can be mixedwith elec-
tronictelephones as requiredbythe user’sapplica-
tion,Standard telephones canaccess alltelephone
features using dial code access.
8.50 DDIWPDIU
8.51 There are four types of Digital Data Interface
Units(DDIUs/PDIUs), DDIU-MAT,DDIU-MA,PDIU-
DI, and PDIU-DS. The DDIU-MAT is a built-in unit
that attaches directly to the bottom of a lo- or
20-buttonelectronictelephone(replacingthebase).
The PDIU-DI is a built-in unitthat attaches directly
to the bottom of both digital telephones (replacing
the base). The DDIU-MA and PDIU-DS are stand-
alone units. Each unit is equipped with a female

RS-232C connector and operation switches. Both
the DDIU-MAT and DDIU-MAare equipped with a
power supply that connects to the DDlUs via a 6’
cord,andplugsinto astandard 117VACwalloutlet.
8.60 Paging Equipment
8.61 A customer-supplied paging amplifier can
work in conjunction with the system’s paging inter-
face and speaker zone switching to provide a
system paging capability.
8.70 Music-on-Hold
8.71 A standard interface enables a customer-
provided music source to be connected to the
system. This music is connectedto all calls placed
in the hold, camp-on or call waiting condition by a
station or the attendant. The same music source
can also be used by the Automatic Wake-up fea-
ture for wake-up calls.
8.80 Universal Night Answer
8.81 Incoming calls, when the system is in night
operation, can be programmed to go either to a
nightanswer station orto a UniversalNightAnswer
devicesuch asabellorloudringer.Any stationuser
can pick up a UNA call by either pressing a m
button on the telephone or by dialing an access
code. Up to two UNA zones can be programmed
per system, when the system is in tenant service.
8.90 Station Message Detail Recording
8.91 PERCEPTIONeLex automatically recordcall
data (suchascallduration, digitsdialed, originating
station and account codes) of calls made to and
from the system. Lodging/Health Care feature ac-
tivation (Automatic Wake-up, Message Registra-
tion, etc.) is also recorded. This data can then
output to a printer, recordingdevice orcall account-
ingsystem. The Lodging/Health Care feature audit
can be combined with SMDR or can be output
separately. SMDR helps the user reduce tele-
phone costs and monitor employee telephone
usage.
