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.
The Sinclair QL and 128k Spectrums used type 630W connectors for their serial ports. These closely resemble standard 631A connectors but the keying slots on the back of the plug have a different size and position.

Use in Hong Kong

Refer to the article Technical standards in colonial Hong Kong.

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.
