Designing an interface to
NET.2 JUNE 1994 2nd Edition Table A-1 V.24/ V.28 ?
Circuits 140, 141, and 142 appear to have become MANDATORY.
Also the pin numbers have changed from the original NET.2:1988,
but this appears to have been a major error which formed the
basis of an amendment issued as
ETSI/STC-TES 90 dated 2nd Feb. 1990
NET.2:1990 stated 140 on pin 14
141 on pin 10
142 on pin 18
NET.2: 1994 states 140 on pin 21
141 on pin 18
142 on pin 25
The latter appears to have been the intended pin-outs from the
outset, with the error being in the original NET.2 1990
More significant, is to determine whether the "*" which depicts
an optional circuit has been left out on purpose, or as an
editorial error.
I have raised the issues with appropriate people and await the
outcome of further enquiries by them.
Meanwhile Treggers you may wish to check your own circuit
pin-outs.
