The LOAD NUMBER (LN) assigned to each terminal device
denotes the percentage of the total load to be connected to a
telephone loop which is used by the device, to prevent
overloading. The termination on a loop may consist of any
combination of devices subject only to the requirement that
the sum of the LOAD NUMBERS of all the devices does not
exceed 100.
