A telephone jack gives a landline phone, intercom or broadband modem a neat wall point instead of a loose cable. This 1 module jack sits in the switchboard next to your switches and sockets, and its shutter flap closes over the opening when nothing is plugged in.
"2 line" refers to the two wires of a telephone line, which connect to the terminals marked L1 and L2 at the back. The jack carries the telephone signal only — it is not a power socket, and LAN (Ethernet) cables need an RJ45 data jack instead.
Where to use it
- Landline phone points in halls, bedrooms and reception desks.
- Intercom points in flats, villas and offices.
- Landline broadband (DSL) modems and fax machines.
- Hotel rooms, clinics and small offices.
How to install
- Switch off the supply at the MCB before opening a switchboard that also carries power wiring.
- Connect the two telephone wires to the terminals marked L1 and L2 and tighten the screws.
- Clip the jack into a free module slot of the plate frame and fit the cover plate.
- Plug in the phone and check for a dial tone.
Keep signal cables away from power cables where possible. Work inside a switchboard should be done by a licensed electrician with the supply switched off.
Frequently asked questions

- Yes, for a landline broadband (DSL) modem that plugs into the phone line. Ethernet (LAN) cables from a router or fibre modem need an RJ45 data jack instead.
- What is the shutter for?
- The flap closes over the opening when no plug is in, keeping dust and insects away from the contacts.
- Which plug does it take?
- Typically the small RJ11-type plug used on telephone cords, intercom handsets and DSL modem cables.
- How much space does it need?
- One module. Pair it with a switch, a TV outlet or a blank plate to fill a 2 module opening.
