3. PRE-INSTALLATION CHECKLIST 
3.1 To make installation easier, use the checklist on 
the following pages when preparing to install the sys- 
tem. (Hardware specifications are included in the 
SPECIFICATIONS section.) 
A. ESTABLISH SUITABLE 
ENVIRONMENTAL CONDITIONS FOR 
THE SYSTEM 
- 
Locate the KSU within 9 feet (3 meters) of an iso- 
lated, dedicated, 10%125VAC, 57-63Hz, 15A, 
single-phase commercial power...

- 
Standard telephone hand tools and the mounting 
hardware for the MDF backboard, KSU, terminal 
block(s), modular jack assemblies, etc. 
3.2 Depending on the type of CO termination used by 
the telephone company and how close it is to the MDF, 
the following tools and supplies are also needed. 
For CO Lines terminated on RJ14 jacks near the

4. STATION CABLING AND 
TERMINATIONS 
4.1 Floor plans should be developed to aid in proper 
station cabling in a star (home run) configuration from 
the KSU. The cables are run from the station locations to 
the station block at the MDF. Refer to page 2-2 for cab- 
ling requirements. 
4.2 Both ends of each cable should be labeled with the 
station’s intercom number: 10-21. Intercom numbers 
lo-19 are for keysets...

B. TERMINATING THE CABLES AT 
time; they will be wall mounted later when the station 
STATION LOCATIONS instruments are installed. Refer to Figure 3-2 below for 
a wiring diagram. 
4.4 Terminate the keyset and single-line set station 
cables on four-conductor modular jack assemblies at the 
station locations. (For exceptions to this, refer to the 
NOTE following section A on the previous page.)

C. TERMXNATING STATION CABLES AT 
THE MAIN DISTRIRUTION FRAME (MDF) 
4.6 The main distribution frame (MDF) is the point at 
which the station instruments, CO lines, and auxiliary 
system equipment are connected to the KSU via termi- 
nal blocks and/or modular jack assemblies. It is ex- 
tremely important that the connections be made 
carefully and accurately. (Refer to Figure 3-l on page 
3-3 for a sample system...

D. STATION LOOP RESISTANCE TEST 
(3) 
NOTE: lf performing the loop resistance test after the 
system is installed, unplug the keyset from the jack 
assembly. Then either unplug the 25-pair station cable 
from the KSU or remove the bridging clips for the 
desired keyset from the station block. 
4.9 Perform the loop resistance test for each station 
cable individually.
