The documentation we have here at AT&T (now Lucent Technologies) shows that connectors should be oriented perpendicular to the wave i.e. reduce the effect known as "combing". Picture a 48 X 2 row connector going thru the wave - it should look like a 2 pin connector as it passes thru the wave. xxxxxxxxxxxxxxxxxxxxxx || xxxxxxxxxxxxxxxxxxxxxx || direction of board travel -------------=> wave Tom Kavendek Lucent Technologies Murray Hill, N.J.
