7.Proposed amendments to Recommendation 0.151

       Change the title of the Recommendation as follows:

                                "ERROR PERFORMANCE MEASURING EQUIPMENT FOR DIGITAL SYSTEMS AT THE  
                      PRIMARY RATE AND ABOVE".  
       In the preamble and section 1 General replace the words,  bit  error
ratio by: "error performance".

       Renumber existing  2.3 to 2.4 and insert a new  2.3 to read:

"2.3   Pseudorandom pattern for systems using 220-1 pattern length 

       This pattern may be generated by a twenty stage shift register  with
feedback taken from the seventeenth and twentieth stages. The output signal 
is taken from the twentieth stage, and an output bit is forced to be a "one" 
whenever the next 14 bits are all "zero".
       The quasi-random sequence satisfies the following:






















       Modify Table 2/0.151 to show both bit patterns 215 -1 and 220 -1  to  be
specified for the 1544, 6312, 32064 and 44736 bit rates.
