mulitlink PPP with Xircom card and Cisco 7200

I have troubles on getting a multilink PPP session working, using a "Xircom Cardbus Ethernet 100 + Modem 56 / ISDN" PCMCIA card.

I use a Cisco 7200 as the LNS, where the L2TP tunnel is beeing terminated. On the client side I set up the Xircom card for MLPPP.

The thing is, that the Cisco 7200 and the Xircom card are not able to get the negotiation done for the second PPP channel.

I see 2 access-interfaces on the Cisco 7200 (bundle and only one L2TP)and after a while the link gets disconnected.

On the other hand there is no problem to have two PPP channels up while using a L2F tunnel with the same modem and LNS.

Does anyone have any relating experience and could help me? Thanks a lot.
