I have some experience with the Fireberd 6000s with various interfaces - and
I use the Agilent Advisor software version on a near daily basis - I really
like it's h.323 capabilities. I did not know that TCC was now Acterna - one
of my co-workers has been crowing about his old Domino Wan boxes that he got
through ebay.
Thanks for the info - I have an email into Acterna for a quote.

ThatC"b,b"s true in the case of the Fireberd and the T-Berd, which are
primarily
used for intrusive testing (in my experience). They donC"b,b"t drill
down (up?)
any further than the L2 frame and don't look at all into the payload. In
the case of the below-mentioned Agilent Advisor, which is primarily used for
in-service monitoring (in my experience), you can look much further up the
protocol stack. I use it for HDLC decodes, for example, where HDLC might be
carrying any number of upper-layer data (and sometimes man-readable ASCII
text), which can be furhter decoded. It doesnC"b,b"t much matter whether
or not
itC"b,b"s v.35, TIA/EIA-232 or 422, whatever (as long as you have the
appropriate
interface module).
