mpc3500 fax rexeption problems

[mrfuser]

Client can receive from me and from another fax in house, but they can't from clients. Very sporadic. Is there a way to slow down modem and turn off error correction or something to fix this?

Thanks all

Probably you should set up a triangular test circuit to see if its a particular telco station causing the problem.
Aside from that: Comm sw 01 bit 0 to 0 will turn off ECM; G3 switch 06 bits3~0 set to 0011 will lower the Rx rate to 7200 bps

Hello
Look up turning off ecm in the fax part of the service manual . It should help

Just to point out that Jomama gave precise instructions on how to do just that, in the only other reply. However, a little feedback as to whether it helped might prove helpful to the rest of us.

I finally got back to client. Turned off ECM and slowed modem to 14.4 and it works perfect!

Thanks all!
