I have no pcap file and i didn`t check in wireshark. I have a file with time sampling, i demodulated it and got the unpacked bits. Then I processed the bit stream with Receiver Program form thishttp://tetra.osmocom.org/trac/wiki/WikiStart#MailingList. But I exactly assured that there is the message D-NWRK-BROADCASTin the bit stream.
You can ask the decoding program to send messages to the GSMTAP port, you can use tcpdump to record a trace and then look at it with wireshark (1.5.x from svn). The people of the Beijing-Institute-of-Technology were so kind to donate their dissector.
This link[1] points to the ASN1 file for the messages, it also provides the D-NWRK-BRDCAST sequence (if you refer for that one).
