Hello Everybody,

we have several Tektronix K1103 protocol analyzers standing around here and it was quite complicated to get the pinout of the SUB-D 9 connectors.

Monitor A:

Pin Purpose

9 RX+B 4 RX-B 6 RX+A 1 RX-A 2,3,4 GND

A = E-1-Linecard -> BTS B = BTS -> E-1-Linecard

Monitor C:

9 RX+D 5 RX-D 6 RX+C 1 RX-C 2,3,4 GND

Telephone socket: 1 mic input (-) 2 hearer output (+) 3 hearer output (-) 4 mic input (+)
