optiPoint Master/Slave telephone HiPath 1120 connections

Warning
!
KS-type system telephones are powered through the C and D wires. Take the nec-
essary precautions to avoid short circuits at the interconnect block. If a short circuit
occurs between wires C and D, the interface's protection will take the extension out
of service. To activate the extension again, remove the short, disconnect the system
telephone then reconnect it. The interface should then start operating normally.
For 2-wire analog telephone sets (A, B) a momentary short-circuit should not cause any
problem.
The maximum distance for installing a KS-type system telephone using a two-pair cable with a
2
0.4 mm copper wire is 0.3 miles and for standard telephones it is 1.5 miles.
