| We hope this will
help you when referring to the many types of adaptors
and linecords on this website.
In the United Kingdom we use two generic types
of plug and socket combinations which are as follows:
The British System
This is a 6 way plug and socket system that was
designed in 1979 and is listed under British Standard
BS6312. The connectors have since been widely
used both in the UK and overseas
The basic 6 way plug is known as 631A while the
UK socket aperture is based on a device known
as the 601A.
The 601A is from a family of sockets known as
the six series (601, 608, 610, etc.) which all
share the same basic aperture. We shall just refer
to it as UK socket. |

The USA Modular
System
This comes in three basic styles of jack and
socket style (although) there are are some variants;
longer, shorter, keyed, etc.) The type known as
RJ11 is the nearest we have to a world standard
and is used in over 200 countries.
| *4 Position |
Handset type |
| *6 Position |
Typically known as RJ11 |
| *8 Position |
Typically known as RJ45 |
It should be noted for the knowledge hungry that
the use of the RJ label for the above types can
be misleading since the RJ designation actually
refers to specific wiring arrangements under the
USOC system. For instance what we commonly refer
to as an RJ11 6P4C plug could technically be called
an 'RJ14C (2 pair)', and so on.
However, for the sake of simplicity we will keep
to the labeling that is now in common use in the
UK. |
