5. Cable installation

5-1 Cable selection

Use 2-conductor telephone or interphone cables for connection from the exchange to the station.

Be sure to use a multi-pair twisted cable such as an indoor cable and CCP-(A)P cable when the connection is

made via the external terminal board.

Select appropriate cables according to the following table that shows the relationship between cable diameter and transmission distance.

Core diameter	Service distance
0.5 mm	1.0km	(1.5km)
0.65mm	1.5km	(2.5km)
0.9 mm	2.5km	(3.5km)

Note

The figure in a parenthesis is the maximum cable length and shown at its left is the normal service distance. The

system supplied from the factory is pre-wired for the

normal service distance. To obtain the maximum cable length, replace the corresponding resistor R31, R39,

R51 or R59 (390k ohms) on the LM unit corresponding to

the line with that of 680k ohms. (See paragraph 6-10.)

5-2 Points to remember
