ISDN Allocation of MSN to Fax

I have 2 DECT telephones linked through a Teledat X120. One is plugged into socket U and the other into socket F and MSNs have been allocated to both phones successfully. I have a HP Office Jet 5610 which has been plugged into socket N on the X120. I understand how ISDN works but I was wondering if it is possible to allocate the 3rd MSN to the fax on the HP 5610. I have tried doing this with no success.

From the manual on the telekom web site:

"Die Nebenstelle „1“ ist universell (U) codiert und kann mit einem beliebigen
analogen Endgerät belegt werden. Die N/F-codierte Nebenstelle „2“ kann an
der N-codierten TAE-Buchse zum Anschluss von Fax und Anrufbeantworter
und an der F-codierten TAE-Buchse zum Anschluss von Telefonen genutzt
werden."

So it looks like the N and F connections are seen as one line and therefore, an MSN assign to Nst 2 will be assigned to devices on both N and F connections.

You might be able to split FAX on N and the phone on F by using disitinctive ringing. I think the X120 allows you to assign distinctive rings according to the incoming MSN. You would then nee to get the FAX and phone to respond to different rings.

It might be easier all round to use an ISDN DECT basestation for the phones and the X120 only for the FAX.

If you are gong to replace your Kit, the seimens CX353 is a superb bit of kit..

3 ansa machines, A/B convertor built in, and Almost any Dect handset can be connected to it..

I love them!! they are so simple and for 199€, a darn good deal!
