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 Failed to parse ip access message: -5 <000d> input/ipaccess.c:331 short read!

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.

Hi Holger,
Right now we do not have any BTS but we are going to have nano BTS it
soon.
So we are trying to communicate between BSC and MSC only without having
BTS.
We created openbsc.cfg file and tried to avoid the BTS configuration in
it and
run but with no success.
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?
