Hi there…
I have returned modem CDM-625 with E1 problem (G.703)according to our field.They already tried to isolate problem by putting LED and measured voltage in the TX port.I tried to check it also by myself the same procedure and check with the other modem but I could’nt measure any voltage in the TX port. Is anyone there who can teach me on how to check propertly and confirm if there is really problem with E1(G.703) so I can request for RMA as this is still under warranty.
Thanks and best regards.
