[edit] Plugs
There are two types of modern British Telecom plugs — 431A and 631A. 431A is 4-way and 631A 6-way. They fit a standard "type 600" telephone socket. There are also plugs with only two contacts commonly seen on modem leads. These are a recent introduction and do not seem to be easily available as separate parts.
[edit] Use in Hong Kong
Refer to the article Technical standards in colonial Hong Kong.
[edit] Use in New Zealand
The BS 6312 jack has been used in New Zealand since the 1980s, replacing a number of other connectors and hard-wired connections. The "BT Connector" is still the most common phone jack in use, although many installations in business use structured cabling with RJ45 connectors for telephone as well as data services.
