Hi,

i am still trying to get hose two BS-11 to run. The hfcmulti driver is
now configured with dmask and bmask (just had the wrong version, thx to
Andreas). But there are still no OML and RSL-connections to the second
BS-11 initialized.

And i found no possibility to put bport1 into multidrop. I appreciate
any help :) !

"The problem is now solved. It seems that we need to create the BPORT1
object on BTS-A, and configure both BPORT0 and BPORT1 into multi-drop
mode. 
Thanks to Dieter for his help with that."
