Unit Loads

Unit Loads
A unit load is a measure of power (1.9 watts) that you use to determine the
electrical load that the components listed below place on the control unit's
power supply.
Telephones and adjuncts
800 DID modules
Only the telephones and adjuncts that connect to the analog and digital
extension jacks (ports) on the control unit require unit load calculation. When
calculating unit load, do not include any equipment with its own power supply.

Checking Unit Loads

In the event of maintenance or equipment changes, recalculate the unit loads
for each carrier where there is a new configuration. Use the worksheet in
Appendix B, ''Unit Load Calculation
As a general rule, if you can distribute the 800 DID modules and telephone
modules equally across the carriers, you prevent unnecessary drain on any one
carrier. However, the rule varies depending on the system's mode. The next two
sections provide the rules for calculating unit loads in various modes.
