4.19.14. Count (Count)

Description: The Count parameter defines the number of time slots that are being mapped to B channels. This value is limited to the value of NumChans since only the number of channels that exist on a line can be mapped to a time slots.

For example, on a T-1 line containing two network interfaces, where time slot 24 is used as a D channel on both lines, the Count for both lines would be as follows:

defineBSet=10,1,1,23, 0,1,1,1,20,1, 1,1,3,23,0
defineBSet=20,2,1,23, 0,1,1,1,20,1, 1,1,3,23,0 

For an E-1 line, Count is set to a value of 30 for lines that contain only B channels. For lines that contain a single D channel, the mapping of channels to time slots occurs in two sets of BChanId, SlotId, Direction and Count definitions. The first set of definitions map the time slots before the D channel, and the second set maps the slots after the D channel. For example, on an E-1 board with four network interfaces, where time slot 16 is used for signaling on all four lines, the Count for all four lines would be as follows:

defineBSet=10,1,1,30, 0,1,1,1,20,1, 1,1,3,15, 16,17,3,15,0
defineBSet=20,2,1,30, 0,1,1,1,20,1, 1,1,3,15, 16,17,3,15,0
defineBSet=30,3,1,30, 0,1,1,1,20,1, 1,1,3,15, 16,17,3,15,0
defineBSet=40,4,1,30, 0,1,1,1,20,1, 1,1,3,15, 16,17,3,15,0 

For all lines in this example, channels 1 to 15 are mapped to time slots 1 to 15 and channels 16 to 30 are mapped to time slots 17 to 31.

For E-1 clear channel lines where the time slot 16 is not used for signaling, additional defineBSet commands are added to clear channel 31 and mapped time slot 16. Count is set to a value of 1 (also the value of NumChans) as follows:

defineBSet=50,1,31,1, 0,0,0,1,21,1, 31,16,3,1,0
defineBSet=60,2,31,1, 0,0,0,1,21,1, 31,16,3,1,0
defineBSet=70,3,31,1, 0,0,0,1,21,1, 31,16,3,1,0
defineBSet=80,4,31,1, 0,0,0,1,21,1, 31,16,3,1,0 

Values: 1 to NumChans
