Telephone Jacks

Sangoma is Unique

Sangoma analog cards use a smaller, handset-sized (4P4C, or so-called "RJ9") jack on the card, and require a special cable with the narrow handset connector on one end and a normal RJ11 (6P2C) connector on the other end. Currently these cables are purple, to distinguish from regular cables.

Types of Connections

Cable connector types

All of these jacks are described as containing a number of potential contact "positions" and the actual number of contacts installed within these positions.

RJ11 - 6P2C.

• 6 Position, 2 Conductor.

This is probably the most familiar of the registered jacks, being used for single line POTS telephone jacks in most homes and offices in North America and many other countries.

RJ14 - 6P4C.

• 6 Position, 4 Conductor.

Same as above, but capable of handling two lines. Capable of plugging into an RJ11 jack and being used as an RJ11 cable.

4P4C

• 4 Position, 4 Conductor.

This is the jack size used on Sangoma A200 analog cards, and is also the de facto industry standard for wired telephone handsets. There are several "unofficial" names for this plug (RJ9, RJ10, and RJ22). Bear in mind, these "RJ" names do not really refer to truly existing ACTA RJ types. Since telephone handsets do not connect directly to the public network, they have no Registered Jack code whatsoever.
