A company called EmCom out of Plano TX makes a box called a NET/QC which
is capable of real-time frame grabbing off of frame-relay (and HDLC,
too) lines. It is intrusive (requires a V.35 T-Cable and retiming
module) and obviously requires physical access. Our 12-line system cost
us around $100,000US.
There is a portable version available that's presumably less expensive.
