The article says: Only RJ11 and RJ14 have full electrical compatibility because Ethernet-compatible pin-outs split the third pair of RJ25 across two separate cable pairs, rendering that pair unusable by an analog phone. At Ethernet frequencies, the signals need to be appropriately paired. At audio frequencies, for usual lengths, probably not. If two were mispaired in the same cable, there might be noticeable crosstalk. Only one, probably not. Gah4 (talk) 06:31, 1 February 2024 (UTC)Reply

A growing standard for radio stations and similar audio wiring is "StudioHub" which uses 8P8C connectors and standard 4-pair UTP cable. Should this be added to this (or other?) page?

This article is mostly about the connectors, and a little about how they are used. There are, for example, Ethernet articles on how to wire them up. If StudioHub is notable enough for its own article, it can go there. Gah4 (talk) 05:00, 9 February 2024 (UTC)Reply

I just made an edit to Template:Registered_jack. It seems that earth and ext. bell were swapped. My sources are:

• a telephone I disassembled (no plug; white, brown and yellow wires used)

yellow is connected to "ext. bell" pin, white/brown to a/b.

• this website: http://www.tocker.de/tae/telefonanschlusskabel/telefonanschlusskabel.html

I also found those telephone wires referred to as "EURO CTR37", but couldn't find a wiring diagram or other useful information.

This is my first edit, hope this helps. ~2026-13555-63 (talk) 16:01, 2 March 2026 (UTC)Reply

The female 8P8C image has the key on the left, but for the image of the male 8P8C connector, the key is on the right. I couldn't find a definitive source for which is correct, but one of those is not correct. Satinlatin (talk) 02:29, 11 March 2026 (UTC)Reply
