64 1’s & 64 0’s

Press this softkey to select a binary data pattern that consists of sixty-four ones 
followed by sixty-four zeroes. If you have selected 

64 1’s & 64 0’s

 in a pattern data 

transmission, both the 

Data

 and the 

Other Patterns

 softkeys will show this 

selection. In addition, 

P64

 (where “P” refers to Pattern and “64” refers to 

sixty-four ones and sixty-four zeroes) is displayed in the 

Data

 field in the top line 

of the text area of the display. If you have selected 

64 1’s & 64 0’s

 in a framed data 

transmission, both the 

TCH

 and the 

Other Patterns

 softkeys will show this 

selection. In addition, 

P64

 is displayed in either the 

Data

 field or the 

TCH

 field, 

both of which are located near the bottom of the text area of the display. A single 
output of a framed P64 data pattern consists of enough repetitions of sixty-four 
ones followed by sixty-four zeroes, followed by sixty-four ones and sixty-four 
zeroes, and so on, until the data fields in the timeslot are filled.
