JuniTimeSlotMap
A bit map representing one or more timeslots of a DS1/E1 interface. Bits are numbered in descending order from 31-0 starting from the most significant bit of the first octet and ending with the least significant bit of the fourth octet. Bits 1-24 are relevant for DS1 interfaces, bits 0-31 are relevant for E1 interfaces. A bit is set if the associated timeslot is in use, and cleared if the associated timeslot is not in use.
