On page 6 they indicate that pins 4/5 are voice tip/ring, 3/6 are mode control, and 1/2 transmit and 7/8 receive. I always thought the pairing was 4/5, 3/6, 2/7, and 1/8. This implys that the pairing is lost on the transmit and receive connections, presumably the most sensitive to crosstalk. Also, on page 11 they say that transmit and receive should be assigned to pairs. Does this mean that 1/2 and 7/8 are really pairs, not 1/8 and 2/7? Could someone enlighten me? -- Plan: To play as much volleyball as possible. Phil Ngai (408) 749-5720 UUCP: {ucbvax,decwrl,ihnp4,allegra}!amdcad!phil ARPA: amdcad!phil@decwrl.ARPA
