PCB Load Factors

In addition to the PCB capacities listed on the previous pages, you must take into consideration the power load
factors for certain PCBs as well as station equipment (such as telephones, telephone adapters, and consoles).
The maximum load factor for PCBs per system cabinet (either 9.5" KSU-B/E or 19" KSU-A) is 7. The
maximum load factor for station equipment is either 64 (for 9.5" KSU-B/E cabinets) or 80 (for 19: KSU-A
cabinets).
Refer to the following charts to determine the load factor for your equipment. Any PCBs or devices not listed
in these charts do not require consideration when determining the load factor. Keep in mind that each 19"
cabinet (either 2 9.5" KSUs combined or 1 19" KSU) has a maximum number of timeslots for audio of 104.
This means that any PCB combination within one system cabinet cannot exceed 104 station or trunk ports.

Make additional copies of these pages for each cabinet to be configured.

The total number cannot exceed 7 for a 9.5" KSU-B/E cabinet or 19" KSU-A cabinet.
The Station Equipment Load Factor must also be considered.
