I was flipping through the Sybex CCDA Study Guide and came upon this in the discussion of LAPB: "Information frames (I-frames) Transport upper-layer information and a bit (no pun intended) of control information. I-frames schlep both send and receive sequence numbers, and relate to jobs such as sequencing, flow control, error detection, and recovery." schlep! Purchase of a CCDA Study Guide online, $30. Yiddish technical jargon, priceless. _________________________________________________________ Do You Yahoo!?
