MP4000 fax give me this error report ( 0-83 )

[Lepus]

Good Days,

As the title, i also attached a sample of a error fax report. Anyone can give me an idea. If using AF1027 no error, transmission is OK. When using MP4000 it happen each time i try to fax out ( from customer Plant 1 to customer plant 2 ).

Thanks.

Looked up the error code in the manual, both service and operator. Then tell us what the manual says and we will translate for you.

Code: 0-83

Meaning:

The line was disconnected due
to a timeout in the V.34 control
channel restart sequence.

Action/Suggested cause:

The guard timer expired while starting these phases.
Serious noise, narrow bandwidth, or low signal level
can cause these errors.
If these errors happen at the transmitting terminal:
• Try making a call at a later time.
• Try using V.17 or a slower modem using dedicated tx
parameters.
• Try increasing the tx level.
• Try adjusting the tx cable equalizer setting.
If these errors happen at the receiving terminal:
• Try adjusting the rx cable equalizer setting.
• Try increasing the tx level.
• Try using V.17 or a slower modem if the same error is
frequent when receiving from multiple senders.

This is wat the manual tell me

This is the full senario:

Customer just switch to MP4000 from AF1027( already used for 5 years ), MP4000 when doing normal fax to others company its all work well in TX and RX, but when customer trying to TX send to opposite factory plant, this error appear. So we try used back the AF1027 its work well, when used back MP4000 error appear again. So i doubt its cause by the cabling and connection problem but more on setting. But i cant find the actual setting to solve this problem.

A suggestion that might help - turn off ECM on the MP4000 and see if that changes things. I think you can do that in the fax section of user tools.
If that changes things for the better, good. You can either leave it that way, or recommend that the fax equipment at the hypothetical plant 2 needs to be upgraded as it doesn't understand modern fax language.
Also, even if you don't think the phone lines are bad, it is useful to check them to be sure. Problem phone lines can cause some weird problems with faxing.

Yes, actually I already advice customer to check the line first but they quite stubborn and called up my boss. So my boss return back their af1027 and tested no error therefore they insisted it's the setting and lazy to check the line. Regarding the ECM, I can't find it under user tools and I suspected its under fax sp and I don't have any idea how to disable it. Anyone can advice on the ECM for MP4000 fax. Really thanks and appreciate all help.

These are both changed through the Bit Switches in the FAX SP mode. v.17 can be set using G3 Switch 05 bits 4 & 5. ECM can be turned off using Communication Switch 01 bit 0. For more information see the Fax Option portion of the Service Manual.

I would recommend only turning off ECM as a last resort. If you have a glitchy line, you'll end up with missing/corrupted data. Adjusting the equalizer setting and reducing the speed should probably be sufficient.

If you don't have a manual then you need to invest in one. The SP codes are pretty universal across all models. Giving you the information here would only be of partial help, something would probably get missed and you will continue to post with more questions. It's time to take the training wheels off son, and if you fall then get right back on.

You can turn off ECM in WIM under fax parameters.

ECM will error out if more than 10% has errors.
10% of 2048 digits per line is almost nothing.
Send it again.
