Yes.
It include dissectors for LAPB and X.25 PLP, and for the low-level
Frame Relay protocol, and you can add more dissectors. (If you add
them, you have to make the source code to the dissectors available to
anybody who gets a copy of those dissectors, and must allow them to
give the source code away to anybody they want to, without
restrictions. Probably the best thing to do is to contribute the
dissectors to the Wireshark code base, which means we can update them
if any dissector programming interfaces change.)
The only tricky part would be if you used Wireshark to do the
capturing. Whether it can capture traffic on a particular network
type depends on whether the libpcap/WinPcap library can capture on
that network type, and that, in turn, depends on the platform on which
you're running, and the drivers for the network adapters.
If you don't use Wireshark, you would have to write the captured data
to a file in a format that Wireshark can read; you can add new file
formats to Wireshark if necessary (the same rules about the source
code apply).
You'll probably have further questions in response to my message; if
they involve making modifications to Wireshark, you might want to ask
them on the wireshark-dev@xxxxxxxxxxxxx list.
