Hi,
I'm trying to use Wireshark (ver. 1.0.5) to decode Tektronik K12xx/K15
rf5 files. I configured Wireshark as described in Wiki -
http://wiki.wireshark.org/K12; and it works fine for most of the files.
But occasionally I'm getting files which were recorded on an HSL
interface (High Speed Interface as defined in Q.703 Annex A). It looks
like Wireshark tries to decode them as normal narrowband Q,703 messages
and ends up displaying everything as an unknown MTP3 SNM message. I've
got the original K12 stack file and I tried to configure K12xx
protocol preferences by adding a new mapping match=hsl protos=mtp2 but
it did not help.
Do you know if Wireshark can decode HSL as per Q.703 Annex A? If so,
how it should be configured to do this correctly?
Try setting the MTP2 preference "Use extended sequence numbers?". That
is used to tell the MTP2 dissector you've got HSL.
