I've just setup a new DCS-816 for a client. Standard system with a dual port BRI trunk card. I have two of the analogue/SLI ports presenting as faxes and accessible to the outside world as DDI numbers. The faxes can send out but do not receive incoming.

If you phone one of these lines from externally the number continues to ring and is never answered - however if you watch the faxes they seems to detects the ring and the modem starts trying to initialise.

One broken fax I could live with, but two doesn't seem likely.

I have tried changing LJUs, using both master and secondary types and have also tried standard phones on the lines which ring as normal and can answer.

If anyone can shed any light I'd be eternally grateful and a lot less stressed!

Don't really know much about the Samsung products but most other systems need to supply voltage to SLI for ringing, some are built in and some aren't. This may be that case for your problem.

The switch will provide the ring voltage.
What about calling from 1 fax to another through the system.I am assuming both faxes are on the system.

I shall go out to site and check the line voltage and try fax to fax across the system.

Many thanks for the input thus far!

The faxes won't send to each other internally across the exchange (ie 213 dialing 214). They flash a receiving message to indicate that the line is ringing, but do not pickup/start negotiating. If I pick up the handset on the receiving fax I can hear the fax modem attempting to connect. If I press receive it will start to connect, but the connection seems to drop out.

This is the same if I fax from 213 to 214 or vica versa.

I looked at the service settings under MMC220 default is set to voice, but have tried modem and G3 Fax for each line with no apparent change.

Doubting my sanity I have even put a new brother fax machine on to extension 213 - again I can send out, but it will not connect and receive incomming!!!

I wonder if the faxes don't like the ring voltage the system is generating.In a perfect world it would be a sine wave but the system is probably generating something closer to a square wave.Can't say I'v really run into that very often but have you connected the faxes directly too a line and it works fine?Is the 2 sli card new or has it been installed in the system for a while?

I'm using the onboard SLI Ports (RJ45 connector below CHAMP) 4 port. Have tried ports 1 and 2 on this (213 and 214). Will have a go with ports 215 and 216.

Make sure that you are pinning out the RJ45 correctly is my next advice.
