The following table details the maximum cable lengths supported for the telephone ranges. These figures
assume that standard twisted-pair telephone cable or CAT5 network cable is used.

Note that the above numbers are for reference only. For practical purposes, for example the calculation of heat
dissipation, it is recommended to base environmental requirements (for example air cooling or UPS ratings) on
the maximum input rating of the power supplies of the planned IP Office configuration, as follows.

In order to calculate the maximum, that is worst case, amount of heat that can be generated by an IP Office
system, it is assumed that all input power is converted to heat; whether from the PSU itself, the system unit,
expansion module and/or cabling.

Heat dissipation is normally measured in British Thermal Units (BTU's). A heat value expressed in Watts can be
converted to BTU/hr by multiplying by 3.41297. As indicated above, you should use the maximum power input
of 115 VA of each power supply to calculate this most accurately.

Using the conversion factor:

· Heat Dissipation = 115 x 3.41297 = 392.5 BTU/hour.

The metric equivalent to BTU is a Joule where 1 BTU = 1,055 Joules.

This calculates the BTU value per power supply. The maximum BTU per system is therefore calculated, based
on total number of power supplies installed in the system. 

· IP500 V2 Maximum Heat Dissipation = 13 x 392.5 = 5,103 BTU/hr.

Remember to budget for the power requirements of any additional devices that are to be co-located with the
IP Office such as server PC's (voicemail, etc).
