I continue to see techs refer to local echo as being too high and<br>
need to be in the teens. This to me is the reverse a high number in<br>
db -60db vs -20 means less echo not more. I would like to know,<br>
as transhybrid loss reflected the true level of "echo" and we had to<br>
make sure the 2w side of the hybrid was matched for the best echo loss, with connections to long local loops this is very difficult and I imagine this is part of the reason for load coils as they would present an impedance of 600 ohms over a band of 300 to 3500 hz. So I guess what my question is are local echo and remote echo being mis diagnost?
