HDLC

A C-size VXI module that provides programmable four or eight RS-232, RS-422 and RS-485 serial interfaces in a single VXI slot. Data transmission andreception can be done with word serial messages ortransparently by passing data through VXI Fast DataChannel buffers. Multiprotocol capability - ASYNC mode standard, HDLC, SDLC, and other bit orien ...more

GL's HDLC protocol analyzer provides the capability to capture, and analyze HDLC data on a full duplex T1 or E1 line. The data channel may utilize all or a fractional part of the T1 or E1 line. ...more

GL's Facility Data Link Analyzer performs FDL decode and analysis on T1 channels in both real time and off-line using saved files with high level data link (HDLC) frames and bit-patterned extended super frame (ESF) data link messages. The real-time mode of operation is used to capture streams of HDLC frames on the selected cards and also embed ...more

GL's Frame Relay Protocol Analyzer can be used to analyze and decode frames conforming to Q.921, Q.922, LAPF, Frame Relay Forum standard -FRF.9 and FRF.12, Multiple Protocol Encapsulation, LCP RFC1661, Q.933 SVC and LMI SNAP, PPP, IP, SMTP, POP3 and so on. ...more
