Professionally installed splitter for DSL lines
DSL telephone lines that are used in the system must have either DSL splitters
or microfilters. If you are using the DSL line for line 1, or if you have more
than three telephones, or if you have an alarm system, you probably need a
DSL splitter. Install this splitter (also known as the network interface device
or NID) near where the telephone lines enter the building. This will allow the
DSL telephone line to be split into two different lines, one for your system
telephones, and the other for your data device. Please seek the assistance of
your DSL service provider or professional contractor to do this installation.
