8.2. Type of Cable
The types of cables are to be determined according to the following conditions.
• Twisted pair wires (such as those used for electronic push-button telephone) are to be used for wiring to the
audio input/output terminals and PBX interface terminal.
• UTP category 5 Straight through cables with RJ45 connector are to be used for wiring the equipments
connected 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.
Note
Specifications related to each junction are as follows.
