- That was what I thought, too. So, before the installer arrived, I had
- already made sure that the yellow/black was wired up for use on my modem
- line.

- In my case, the Illinois Bell installer moved the connection from indoors
- to outdoors. He installed a box just outside, with three line connection
- interfaces in it. Each interface consisted of a 4 terminal wiring block
- and a modular jack to disconnect the line. He also ran 4 wires back
- into the house to connect to the original red/green/yellow/black lines.
- He connected the original incoming line to the first wiring block, which
- he connected to the red/green running back into the house. He connected
- the yellow/black from the house to the second block, and he left the
- third wiring block with no connections leading back into the house.
-
- Naturally he connected the second phone line to the third wiring block,
- meaning that the second line did not come into the house. I presume
- this was just to make sure that he was not doing any inside wiring for
- the new line (I am not paying for their inside wiring service). Thus
- what could have been a 5-minute job took him more than one hour. Not
- a problem - I was not paying for that part of the job (I had the second
- line installed during a "free installation" promotion), and moving the
- yellow/black pair to the 2nd block was easy enough.

-
- Perhaps this depends on the type of telephone. Many 'phones seem to work
- and dial out with either polarity.
