Diagnosing line quality problems with v.32 (or less) modems.
Posted on 2001-08-27
Is there any way to diagnose and/or test for telephone line quality problems at a remote site when establishing a V.32 or V.22 connection between modems? I am seeking the same type of "Link Diagnostic" information that is reported on V.34 or V.90 connections (such as SNR, Xmit/Recv levels, frequency response, etc). Specifically, I am looking for the same information that I get from my USR 56k modem by sending the ATI11 and ATY11 commands. The information from ATI6 command is very useful, however, it can't help in diagnosing excessively high signal levels or Loop Loss at the remote location.
