A. KEY SERVICE UNIT (KSU) SITE PLANNING 
2.02 Prior to installing the 824 equipment, select a centralized 
location for the KSU and Main Distribution Frame (MDF) which will 
minimize cable run lengths from each station and provide the 
proper environmental conditions. 
A. Availability to 105-125VAC, 
60Hz single-phase commercial 
power. 
NOTE : This must be a dedicated, 
separately fused AC in- 
put for proper...

A. RUNNING CABLE 
3.03 Run two-pair cable to each station location shown on the 
floor plan. Both ends of every cable must be labeled with the 
circuit number. Run one-pair cable to each Door-Mate location.

4. ASSEMBLING THE MAIN DISTRIBUTION FRAME (MDF) BACKBOARD 
4-01 The MDF is the point at which the KSU, the stations, and 
the C.O. lines are connected to one another. It is. extremely 
important that this be done accurately. 
4.02 The MDF backboard should be constructed to present a neat 
appearance, readily facilitate changes, 
have cables of proper 
length, and be correctly labeled. A 3X4-foot 3/4-inch plywood...

A. CONNECTING C-0. LINES TO THE MDF 
.: 
4.03 Central Office (C.O.) lines are typically terminated on an 
RJ-21X or RJ-14C connector. 
Then you terminate the lines on the 
MDF. Refer to Figure 3-3 on the next page. 
(1) One connection block on the MDF is dedicated for all C.O. 
line connections. Terminate 
a 25-pair cable from the 
right side of this block to the RJ-21X or RJ-14C. 
Label 
both ends. 
(2) Make an MDF PCB...

B. CONNEXTING STATION CABLES TO THE MDF 
4.05 After station cables are run, 
they are connected to the MDF 
as described below. Refer to Figure 3-4 and Figure 3-5 on the 
following pages. 
(1) 
(2) 
(3) Ensure both ends of the cable are labeled with the cir- 
cuit number. 
Terminate each station cable on the right side of the 
designated KTI block. 
NOTE : Each KTI block supports up to 12 stations.
