11.05 Overload. The change in attenuation when the level of a 1004
Hz signal is increased from 0 to +lO dBm shall not exceed 0.2
11.06 Return Loss. The Return Loss parameters are greater than:
Line-to-Trunk Structural Return Loss
ERL 20 dB

11.08 Crosstalk Attenuation. The crosstalk attenuation, or coupling
loss, between any two transmission paths is as stated below.
Both paths are terminated in 600 or 900 ohms as required at each end.
The frequency band which applies is 200 to 3400 Hz.
Line-to-Line -75 dB minimum
Line-to-Trunk -75 dB minimum
Trunk-to-Trunk -75
The level of the disturbing signal is 0 dBm.
