( Connection between the KSU, Key TEL and CO/PBX line
Make connections between the KSU, Key TEL and the central office/PBX line (CO/PBX) according to the following procedure.
0
Connection between the KSU and
CO/PBX line
Connect COL No. 1 through No. 6
jacks provided inside the KSU to the
CO/PBX line, respectively.
0 Connection between the KSU and Key
TEL
Connect EXT No. 10 through No. 21
jacks provided inside the KSU to the
key telephones, respectively.
EXT No. 10 is desirable to use an LCD
display type key telephone (VA-12022
or VA-12022-B) that is used for the
PROGRAMMING purpose described
later. (see page 28.)
0 Clampring of cords
@ Push in the cables from the top of
the cable guide.
@ Remove the clamp plate, insert
the cords, then reinstall the clamp
plate over the cords and secure
into place with the screw.
NOTE
0 Keep the loop wire resistance to the
key telephone furthest from the key
service unit less than 40 ohms. (Max.
1100 feet with 22 AWG cable)
l
Do not wire the telephone cable in
parallel with the AC power source,
computer, telex etc. If the cables run
near those wires, shield the cables
within metal tubing or use shielded
cable and ground the shields.
l
When cables run on the floor, use pro-
tectors or the like to protect the wires
where they may be stepped on. Avoid
wiring under carpets.
0 When using an AC power supply (AC
12OV), make sure the unit is ground.
