Wiring the distribution frame
No dedicated wiring system is required for the M6501L/R IP PBX.
Nevertheless, you are recommended to use the Systimax Premises Distribution System. This
system is designed to ANSI/EIA standards, and as such has ISO type characteristics suitable for
wiring categories 1 to 5.
Note: The principle for connecting equipment to the M6501L/R IP PBX is based on the use of
telephone pairs for capillary wiring.
Organisation of the distribution frame
The system's distribution frame is made up of rails fitted with connector strips. An example
distribution frame layout is shown below:
Protection against line overvoltages
For a new system, it is advisable to use protection modules to protect against PSTN line
overvoltages.
These modules are inserted between the PSTN and the system's distribution frame.
