OPTION INSTALLATION DETAILS 
DSWBLF CONSOLE CONNECTION 
The optional DSS/BLF console may be installed at any 
station port to work in conjunction with a companion 
station connected to the adjacent port (e.g.; port 10 for 
station and port 11 for console). Console port 
installation is illustrated in Figure 3-3a and 3-3b, 
shown on the previous pages. 
The model EB32X-xx, DB32-xx, DB32S-xx, DB40-xx, 
and DB70-xx DSS/BLF consoles are all compatible 
with the XE system. The station port to which they are 
connected must be programmed as a DSS/BLF 
console port. The console keys are fixed for DSS/BLF 
operation beginning with station 10 and ending with 
the maximum station number in the system. The 
remainder of the keys are blanked and are unuseable 
for any other purpose. 
For this reason it is 
recommended that the larger consoles (DB40 and 
DB70) not be used unless absolutely necessary since 
the XE system has a maximum station capacity of 
twenty-four stations thus leaving these consoles with a 
large quanity of blanked keys. 
l The installed distance limit between the common 
equipment and a console is the same as that 
specified for a regular station. Connect all four 
wires (voice pair and data pair) of the console cable 
to the station connector block. 
The voice pair connections of the console can be 
used simultaneously to enable a PA port function or 
to provide off-hook voice announce capability.. 
See information headed External Paging interface - 
Station PA Port. If an enable signal is required with 
the particular PA equipment being used, the 
console and PA equipment connections are limited 
to station ports 15 and 17. 
The DSS/BLF console port must be programmed as 
a DSS/BLF port before console operation can take 
place. 
The console port must be also programmed as a PA 
port if a PA amplifier has been connected to the 
voice pair as part of the system. 
OFF-HOOK VOICE ANNOUNCE 
WITH HANDSFREE ANSWERBACK 
The DB32S-xx Adjunct Feature Module can be used 
to provide off-hook voice announcing (OHVA) to a 
station already busy on a call and allow subsequent 
handsfree answerback (HFAB) by the station user; however, the DB32S-xx Module can not be used as a 
DSS/BLF console at the same time. The station port 
to which the Adjunct Feature Module is connected 
must be programmed for whichever of these features 
that is required. Two data-paired station ports are 
required to provide the OHVAlHFAB feature. 
l Connect a keyset to the first data-paired port 
* Connect the DB32S-xx Adjunct Feature Module to 
the voice pair and the data pair of the second 
data-paired port. 
For the feature to be enabled, the port to which the 
Adjunct Feature Module is connected must be 
programmed as an Off-Hook Call Announce port. 
SECURE OFF-HOOK VOICE 
ANNOUNCE STATION 
The XE system supports the Secure Off-Hook Voice 
Announce (SOHVA) feature provided by the following 
keyset models. 
. 6714X-xx 
. 68OOS-xx 
. 68148 
. 6820X-xx 
. 682OS-xx 
NOTE: If normal off-hook voice announce capability is 
required, it is provided by fhe model DB32S-xx 
console as described in the previous 
paragraph. 
Two data-paired ports are required to provide SOHVA 
support. The SOHVA equipped telephones contain a 
6-position, 3-pair line jack. Using 6-wire, twisted-pair 
cable, connect the two inside pairs of the line jack to 
the first data-paired port and connect the outside pair 
to the second data-paired port. Refer to Figure 3-4 for 
an illustration of this wiring. 
* Connect pins 3 and 4 to the voice pair and pins 2 
and 5 to data pair of the first data-paired port. 
l Connect pins 1 and 6 to the voice pair of the second 
data-paired port. 
For the feature to be enabled, the first port must be 
programmed as a keyset port and the second port 
must be programmed as an Off-Hook Call Announce

POWER FAILURE STATION 
The system provides one tip and ring pair connected 
to line one as an emergency, power failure circuit. 
This power failure pair is located on Mod jack 1 for all 
common equipment models. This jack is the rightmost 
jack when facing the right side of the cabinet as shown in Figure 3-5. The power failure pair is only active 
during an AC power failure. An industry standard 
single-line telephone, such as a Comdial2500-xx can 
be connected to the power failure pair and used to 
provide communications capability should the AC 
power to the system be interrupted.

Two sets of relay closure dry-contact points are 
available. These are located at the J-l and J-2 
connector blocks for models NO61 6, N0820, and 
N1024 and at the barrier-type terminal strip on the 
model NO308 common equipment cabinet. These

during the ringing period and open during the silent 
period. Figure 3-6 shows connection details for this 
feature.

Any station port can be programmed as a PA port and 
used to couple a station voice path to an external 
paging amplifier. Refer to Chapter for programming 
details. Figure 3-7 shows connection details for this 
feature. 
l The audio input of an external paging amplifier can 
be connected to the audio pair of the station port at 
the J-l or J-2 connector blocks for models NO61 6, 
N0820, and Ni 024 or at the barrier-type terminal 
strip on the model NO308 common equipment

600 ohm to 600 ohm audio matching transformer. 
l If station port 15 is programmed as a PA port, 
the Common Audible contact points on J-2 are 
automatically reconfigured as PA enable terminals. 
The contact closure now occurs when PA station 15 
is dialed. The normal common audible function is 
disabled as long as station 15 is a PA station. 
l If station port 17 is programmed as a PA pot?, 
the Auxiliary Station Interface (station 17 audible) 
contact points are automatically reconfigured as PA 
enable terminals. The contact closure now occurs 
when PA station 17 is dialed. The normal auxiliary

FAILURE ISOLATION 
SYSTEM STATUS INDICATOR 
The red LED located near the fuse holder is the 
system status indicator. This indicator should turn on 
steady when AC power or the optional external battery 
power is applied to the common equipment. If the 
indicator flashes after power up, it could be indicating 
a processor failure. Unplug and reconnect the AC 
power, and observe the LED indication. If it still shows 
a flashing indication, equipment replacement may be 
necessary. A flashing indicator when battery power is 
being employed is an indication of battery discharge. 
STATION SELF TEST 
1. Disconnect the line cord at the station base. 
NOTE: The adjacent odd or even station will be 
disabled during the time that the station line 
cord is being disconnected and reconnected.. 
2. Press and hold the MUTE key, and reconnect the 
line cord to the station connector. The station will 
automatically perform a self test routine. Release 
the MUTE key as soon as the test begins. The 
sequence of the test is as follows: 
l The indicators will light in sequence. 
l Indicators will then turn off in an orderly 
sequence. 
l The ringer will sound - Be sure that the ringer 
volume control is set to the medium or high 
volume setting. One some telephone models, the ringer may sound before the indicators are 
turned off. 
3. Replace any station that does not pass the self test. 
DSS/BLF CONSOLE SELF TEST 
1. Disconnect the console line cord plug from the line. 
2. Press and hold the station 10 select key while 
reconnecting the line cord plug to the line. 
NOTE: The companion station will be disabled during 
3. 
the time that the console is being disconnected 
and reconnected. 
Release the station 10 select key, and note that the 
BLF indicators will each turn on in sequence 
beginning with the station 10 indicator. The 
indicators will then turn off and the console will 
become operational. 
FAILURE INDICATIONS 
If erratic light indications or ring signals occur at a 
paired station, an open data pair at either station may 
be the fault. 
l A station with an open data line may work properly 
on a short loop but fail on a long loop. 
Stations are paired for overload current protection. If 
a fault occurs which causes more than 300 ma. of 
current to be drawn, the paired stations are disabled 
by circuit action. 
Disconnect the disabled stations and reconnect them 
one at a time to isolate the faulty one.
