Installing the SOMAport 140
Connecting telephone equipment to in-building
telephone wiring
You can connect the SOMAport 140 to your in-building telephone wiring by
plugging it into a wall phone jack. The benefit of using this method is that you
can connect a number of telephone devices (phones, fax machines, dial-up
modems) that are located in other rooms to the SOMAport 140. When you plug
these devices into other phone wall jacks, they are connected to the SOMAport
140 through the wiring in your building. However, all of the connected devices
share the same phone line so that only one of the connected devices can be in
use at one time.
The telephone company connection
The phone line that the SOMAport 140 uses cannot also be connected to the
telephone company. If both the telephone company and your service provider
(via the SOMAport 140) try to provide service on the same line, there will be a
conflict and the SOMAport 140 will not work. Only connect the SOMAport
140 to a phone line that is not connected to the phone company. If you get dial
tone on a phone that is connected to a phone line (via a wall phone jack), then
the line is connected to the phone company.
Using the second phone line wiring for the SOMAport 140
You can connect the SOMAport 140 to the in-building wiring if you have one,
two, or more phone lines. The telephone wiring in most buildings contains two
pairs of wires for two phone lines. One pair is for Line 1 and the other is for
Line 2. (Older buildings may be wired for only one phone line and newer
buildings may be wired for more than two lines.)
If you have two phone lines and want to connect the SOMAport 140 to the in-
building wiring, it is recommended that you do the following:

Leave Line 1 connected to the telephone company if you wish to continue
using the telephone company for your phone service. Phone service can also
be obtained through your service provider.

Connect the SOMAport 140 to Line 2, making sure that Line 2 is
disconnected from the telephone company.
