Chapter 3 INSTALLATION & WIRING
13.13. Type of Cable
The types of cables are to be determined according to the following conditions.
• To use twisted pair wires (such as those used for electronic push-button telephone) for wiring between the
Exchange and the stations, for wiring between the N-8400RS Substation interface unit and the N-8410MS
Master station or the RS-450/460/470/480 Substations, and for connections to the Multi interface unit's audio
input/output terminals and PBX interface terminals.
• Use a straight through cable of UTP category 5 or more with RJ-45 connector for wiring the equipment to IP
network.
• The number of cables pairs laid should be determined considering the possibility of future expansion of the
system.
• Outdoor wires should be used where wiring passes through inaccessible areas such as ceilings or under
floors where the maintenance is not performed. Indoor wires may also be used, however, in case where there
is no risk of deterioration due to exposure to heat, etc.
• Make sure that the 2-core shielded cable is used for wiring from the N-8000RS/8010RS Substation interface
unit to the RS-150/160/170/180 Substation , RS-140/143/144 Switch panel, or RS-142 Switch board.
