Hello,

Tried port and got message:

<0010> gprs_nc.c:627 NSEI=101 Rx NS STATUS cause=PDU not compatible with protocol state
<0010> gprs_nc.c:489 NSEI=101 Tns-alive expired more than 10 times, blocking NS-VC

And nothing has changed, still get Rejecting PDU for unknown BVCI.

Could you please provide me your config files which are working?

Regards,
Sergey.
