ABIS in normally over TDM I think

So what sort of framing does it use? Probably HDLC framing, but is there just an Abis PDU between the two flag octets, or is there some additional information?

and I know of no capturing device that can be used writing a file usable by wireshark.

With an appropriate DLT_ value, and support for that DLT_ value as one of the choices in the libpcap DAG card support, it might be possible to use an Endace DAG card to capture that traffic.
