The following notes apply to the Single V.35 DTE cable:
1. At each end, the cable shield and connector shell must connect respectively to pin A of the 34-pin
connector and pin 1 of the standard 28-pin connector.
2. The term "no conn" means the wire is not connected to a pin in the 34-pin connector.
3. Wires 12B, 13A, and 14B connect to pin B in the 34-pin connector.
4. Unused pins in the 34-pin connector need not be present.
5. Do not connect Shield to Signal Ground as these are separate signals.
6. The pair suffix A or B refers to an individual wire within a twisted pair.
