Osmocom's Base Station Controller for 2G mobile networks

When using ISDN as network type and using a fake LAPD encapsulation
wireshark should be able to recognize some bits if dump.
Append a dummy LAPD header. It is not clear to me if the Control field
of the LAPD frame is part of the msg or if we need to add it as well.
TODO:
- Do the same for the B Channel
- Write out time
- Check if more of the LAPD frame needs to be prepended. The
information from the mISDNhead comes into mind. Maybe it makes
sense to start a custom wireshark mISDN dissector.

About OpenBSC ============= OpenBSC is a minimalistic implementation of the GSM Network, with particular emphasis on the functionality typically provided by the BSC, MSC, HLR, VLR. Its only current interface is a mISDN based E1 interface utilizing the A-bis protocol between BSC and BTS. In other words, you can connect an existing GSM Base Transceiver Station (BTS) through E1 to OpenBSC. So far, it has only been tested with the Siemens microBTS BS-11. Test reports with other BTS are appreciated! This project is still in its early days, and there are lots of areas where it doesn't behave as per GSM spec.
