- - ---UC - 
The optional DSS/BLF console may be installed at any station port 
to work in conjunction with a companion system station connected 
to the adjacent port (e.g.; 
port 10 for station and port 11 for 
console). The installed distance limit between the KSU and the 
console is the same as that specified for the 
companion station. 
Connect all four wires (voice pair and data pair) of the console 
cable to the station connection block. 
The voice pair connections of the console can he used 
simultaneously to enable a PA port function. 
Refer to the 
paragraph in this chapter headed Dial $c_$ie;g2 $&$ eddress. Port, 
and to the illustration shown in F?Gcre 5. Per that ~-?~,~,s;~~~ 
wire a PA amplifier input to the DSS/BLF console voice-pair at 
the station connector block clip terminals. 1Jse an audio 
matching transformer, as discussed in the referenced paragraph 
and illustration, to provide isolation. If an enable signal is 
required with the particular PA equipment being used, the console 
and PA equipment connections are limited to the station ports 
specified in the above mentioned reference. 
The DSS/BLF console port must be programmed as a DSS/BLF port 
(see Chapter 4 for programming details) 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.

Check the KSU and telephone installation for proper operation by 
performing the following actions. 
1. Before any AC power is applied to the system, measure the 
resistance across each station voice and data pair. 
Disconnect the 25-pair cables from the KSU at the 66M-xx 
connector blocks but leave the stations connected. Make the 
measurements from the blocks (refer to Figure 3 to identify 
the connection points of the voice and data pairs). The 
measured resistance must be as follows: 
VOICE PAIR: 45 OHMS TYPICAL (40 OHMS MIN.--150 OHMS MAX.) 
DATA PAIR: 
45 OHMS TYPICAL (40 OHMS MIN.--l50 OHMS MAX.) 
Readings which are outside of the above range indicate a 
possible wiring or station problem. 
2. Connect the 25-pair cables, and plug the AC power plug of the 
KSU into the electrical outlet.

initiate and receive an outside 
line and an intercom line call. Be sure to set the ringer 
volume to the medium or high volume setting at each station. 
7. Exercise every feature and option available at each 
individual station. Be sure that the line select indicators 
and any other indicators function properly.
