Hi Holger,

We are able to connect to MSC but after it gets connected, it throws below error:-

ozmank@ozmank-desktop:~/libosmocore/openbsc/openbsc/src$ ./bsc_msc_ipBootstraping the network. Sending GSM08.08 reset.
<000f> bsc_msc.c:135 Attempting to connect MSC at 130.238.15.219 :58620
<000f> bsc_msc.c:168 MSC Connection in progress
<000f> bsc_msc.c:97 (Re)Connected to the MSC.
<000d> input/ipaccess.c:323 Can not read this packet. 12336 avail

<000d> input/ipaccess.c:331 short read! Got 4 from 114

<000f> bsc_msc_ip.c:1047 The connection to the MSC was lost.
<000f> bsc_msc_ip.c:976 Lost MSC connection. Freing stuff.

So We are wonder that if we are sending some wrong packet OR wrong packet format from MSC to BSC as it is throwing cannot read the packet.

Can you Please advice.

Well, you decided to copy to a config for the Siemens BS11... if you copy one
of the examples for the nanoBTS the BSC should come up, if your address of the
MSC (nowadays it is better to put it into the bsc.cfg) is correct, the BSC
will connect to it and send a GSM0808 RESET to it.

All you can test without a BSC is to send Paging messages from the MSC to the
BSC (as they do not require any connection).

Do you have a link to your university project?
