I'm currently working on a project with an old device that exposes at least one V.35 interface. From my understanding and reading. V.35 commonly used a huge, bulky connector that looked like this:
However, this is huge and likely wasn't a good connector for things that needed a smaller form factor. I know that many companies used all sorts of custom connectors for V.35, in fact my device uses a DB44 connector. However, I got curious. This website notes (emphasis mine):
The V.35 plug is standard. It is a black plastic plug about 20mm by 70mm, often with gold-plated contacts and built-in hold down and mating screws.
I've looked at the V.35 standard available at: https://www.itu.int/rec/T-REC-V.35/en and can't find a single mention of this plug. In fact, there seems to be very little defined about the cable or plug itself. Am I missing it? Was this bulky connector actually ever "standard" for V.35? If not, where did this design come from?
