That's in the libpcap 0.9[.x] source.  You do need to recompile libpcap, 
with a special configure option, as that feature uses Intel's 
Septel/NetStructure software - libpcap has to be linked with it.  It 
should work on Linux.  It might be possible to make it work on Solaris; 
somebody with Solaris and Septel/NetStructure cards and software would 
have to do the work (which would involve transplanting the changes made 
to pcap-linux.c to pcap-dlpi.c).

It might also be possible to capture it with some DAG cards from Endace 
and the latest version of DAG software, as well as libpcap 0.9[.x] - if 
you have an "HDLC" line, the link-layer type choices (which should 
appear in the Ethereal GUI) offered are Cisco HDLC, PPP, Frame Relay, 
and SS7 MTP2.
