6.4.14.4 Coupling attenuation
Move the existing third paragraph from before Table 22 to after Table 22:
It is possible to assess coupling attenuation by laboratory measurements of representative samples of
channels assembled using their component and connector termination practices.
Page 25 of Amendment 1
6.4.15.1 General
Replace the existing second paragraph by the following new second paragraph:
If coupling attenuation for Class E or F channels is 10 dB better than Table 22 or for Class F
A A
channels is 25 dB better than Table 22, then the requirements of 6.4.15 are met by design.

6.4.15.2 Power sum alien NEXT (PS ANEXT)
Replace the last identifier by the following identifier:
ANEXT is the alien near-end crosstalk loss coupled from pair i of disturbing channel (l) to the
l, i,k
pair k of the disturbed channel.
Page 26 of Amendment 1
Table 23 – PS ANEXT for channel
b
Replace the last line of footnote by the following line:
IL is the insertion loss of a pair i at 100 MHz.

Replace the fourth identifier for equation 9 by the following identifier:

AFEXT is the alien far-end crosstalk loss coupled from pair i of disturbing channel (l) to the
l,i,k
pair k of the disturbed channel;

Replace the last identifier for equation 9 by the following identifier:

IL is the measured insertion loss of pair i of disturbing channel l.

Replace the last identifier by the following identifier:
AFEXT is the alien far-end crosstalk loss coupled from pair i of disturbing channel (l) to the
l, i,k
pair k of the disturbed channel.
