You tin mix and friction match the way you connect your wiring at different locations depending on your requirements. For wall jacks, such as those found in most kitchens, you lot will desire to use the first method shown below. This puts both lines on 1 jack, to permit utilise of a 2 line telephone if desired. If you desire to exist able to limit which lines tin can exist accessed at a particular location, such equally to provide a teen-ager admission to merely line 2 in their sleeping accommodation, you'll want to use a variant of the 2nd method. For most of your jack locations, I recommend utilise of the third method. This method will allow you apply either your existing unmarried line sets or special ii-line sets. This pick also provides yous with great flexibility by permitting access to either line as "line 1" on pins 4 and 5 of a jack. This provides for connection of a unmarried line device such as a fax machine or modem to either line without use of adapter plugs.

You have several options on how to connect your jacks for two lines:

Line 1 and Line ii on one jack (easiest way to use "2-line" phones and may use of existing jacks with adapters)
Line i and Line 2 on separate jacks (easiest way to use your existing single line phones)
Both of the in a higher place (this is what I recommend - provides the most flexibility without using expensive adapter plugs)

The back of most screw last jacks are marked with letters indicating the colour of the wire to connect to the concluding and have wires from the terminal to the bodily jack. On some of the diagrams below, I've left the wires from the screw terminals to the bodily jacks off the diagram for clarity. Leave them on the screw terminals that match the markings.

Connecting Lines on One Jack

Connecting your jacks in this manner may allow apply of existing jacks. You may fifty-fifty find that your jacks are already connected in this manner. However, you should cheque to ensure that the black and yellow pair is continued for line two. I'll bear witness the connections for spiral concluding jacks.

This is the most unproblematic connection. To connect both lines on 1 jack, simply connect the wires from your cable to the matching screw terminal. To apply line two with a unmarried phone or other single line device on a jack wired in this manner, you'll need to use an A/B Splitter Adapter.

Connecting Lines on Carve up Jacks

Connecting your jacks in this manner will crave that you apply faceplates with two jacks, unless y'all only desire one line to announced at a particular location. I'll show screw terminal jacks connections.

To connect line i to the top jack, connect the green wire on the screw terminal marked for light-green and the cherry wire on the screw terminal marked for ruddy. To connect line ii to the bottom jack, connect the blackness wire on the screw terminal marked for green and the yellowish wire on the screw concluding marked for carmine. If yous want only one line to appear on a single jack, merely connect the pair for that line to the screw terminals marked for dark-green and red. Use a small piece of electrician's record to insulate the exposed copper on the wires of the other pair so that they do not short to each other or to something else.

Connecting Both Lines on Ii Jacks

Connecting your jacks in this manner will require that y'all use faceplates with two jacks. I'll show both spiral terminal jacks now. I'll add a diagram for 110-punch jacks at some point in the future.

To connect your jacks in this manner, first remove about vi inches of cover from the terminate of the cable. Near 4 inches from the end of each wire, remove almost a half inch of insulation. This gap in the insulation is looped effectually the screw terminals on the height jack. Connect the loop on each wire to the matching screw last of the top jack.

Now connect the terminate of the wires to the bottom jack every bit follows: blackness wire to the spiral concluding marked for greenish, yellow wire to the screw last marked for reddish, greenish wire to the screw terminal marked for blackness, and ruddy wire to the screw terminal marked for xanthous.

A "two-line" phone continued to the pinnacle jack will be connected to both lines. A ii-line device would likewise be connected to both lines on the lesser jack, merely "line appearances" would be reversed.

A single line device connected to the top jack will be connected to line one. On the bottom jack it will be connected to line 2.
