That�s true in the case of the Fireberd and the T-Berd, which are primarily used for intrusive testing (in my experience). They don�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 doesn�t much matter whether or not it�s v.35, TIA/EIA-232 or 422, whatever (as long as you have the appropriate interface module). >In the > T-Carrier and Frame Relay world, the test set can lock to the > frame, verify the FCS, etc. I've also used the Agilent Advisor > (formerly the HP Internet Advisor) quite a bit, which is a > Windows-based test set for both LANs and WANs.
