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. - Jim --------------------------------------- V.

I'm familiar with the ones from Netscout (formerly Frontier) and Concord, and Bay (which bought Armon) and 3Com (which bought Axon) may have something as well. One of the RMON groups is capture, and these probes' management packages show capture buffer contents using decodes that look the Network General Sniffer. Speaking of the Sniffer, Network General and several other vendors (HP, RADcom, TTC, Wandel & Goltermann) have V.35 interfaces for their analyzers. Can't vouch for the existence quality of the frame relay decodes, though. Regards David Newman Data Communications magazine
