Connecting telephone equipment to in-building telephone wiring
Installing the SOMAport 140
2
Look at the telephone wall phone jack.

If you see four pins, then the wall jack is probably wired for two phone lines.

If only two pins are visible (the middle ones), then the jack is wired for one
phone line.
Connect telephone equipment directly to the SOMAport 140 or call the
telephone company to rewire your jacks and in-building wiring for two lines.
Two-line splitters
In addition to making sure the wall phone jacks are properly wired, you need to
be able to connect equipment to Line 2. Standard telephone wall phone jacks
have only one connector that allows you to connect telephone equipment to
Line 1. To use both lines, you need a special adapter called a two-line splitter.
This is a 2-way jack that is plugged into a standard telephone wall phone jack.
This special adapter can be purchased at most electronics stores and office
supply stores.
