Kevin, I agree with others that the use of 15-pin D connectors for digital applications is limited to North American T1, 1.544 Mb applications. In our gear we use pins 1&9 as transmit (out towards the network), pins 3&11 as receive (from the network), pins 8&15 as chassis ground, and pins 12 and 14 as T1 Remote Loop-Back Tip, minus and plus, respectively.
I have not found the source document for the 15 pin D pinout, but the RJ45 and coax pinouts are specified in ISO/IEC 10173, "Information technology - Integrated Services Digital Network primarary access connector at reference points S and T." Good luck, Pete ____________________________________________ On 10/13/98 Kevin Keegan wrote: > Dear Treggers: > > Is there a consensus of opinion on the pin-out for the 15 pin D-type > connector (in the 15 pin package) for E1 (2.048 kbit/s digital) > communications?
