Plugs
There are two types of 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.
