Checking a phone at the phone system using a standard phone jack

Posted on by

Find a standard telephone jack. This is a two port jack but only the top one will be used.

Phone Jack

Find some wire to use. You can use the cross-connect wire supplied with your phone system or you can cut a piece of spare wire. Make sure the wire has a solid core and is not stranded, stranded wire does not make a good connection on the 66 block.

Strip the wire so the copper is exposed.

Connect the stripped wire to the Red and Green terminals on the jack.

Connect the other end to the 66 block at the extension you are testing. In this example we are checking extension 201.

66 block

Punch down the wires using the punch down tool provided.  If you do not have a punch down tool scroll down to see how to connect the wires without a punch down tool.

If you do not have a punch down tool you can twist the wires onto the 66 block. Try not to touch the wires together.

Now plug a phone into the front of the jack.  If your phone works the phone system is OK and there may be an issue with the cable.

Connecting Music Or Message On Hold To A NEC DSX

Posted on by

The NEC DSX-80 and DSX-160 telephone systems have 3 1/8″ minijacks located on the CPU card. The 2 minijacks closest to the outside are the audio inputs. The first minijack is audio in 1, the second is audio in 2 and the third is a page output. To connect music-on-hold you will need a mono audio cable with a 1/8” minijack on one end and a connector that matches your music player on the other end.

By default the NEC DSX is programmed to play music from audio source 1. This can be changed on a line by line basis in program 3103-05. If you want a true message on hold system, one that will play advertisements or specials for your company we recommend the OHP 8000. It comes with all the required cables to connect to the NEC DSX telephone system and includes some nice software if you’re the creative type and would like to make your own messages.
