You'd also need some sort of tap functionality on the card to insert it
Between the MSC and the PRA.

An Endace DAG card:
http://www.endace.com/dag-3.7t-datasheet.html
might be able to do it; libpcap can be built with support for DAG
cards, and a version of Wireshark that uses that version of libpcap
could capture on them.
However, Wireshark doesn't currently dissect LAPD captured from them,
so some work would be needed to have Wireshark dissect the resulting
capture.
