Getting Started
Important Notes for DSL users:
If you are a DSL customer, you may experience interference with the advanced
system features of your TMC telephone.
Certain features of this telephone work by sending a data or intercom signal over
Line 1. These signals use some of the same frequencies that are used by the DSL
service.
The microfilters that may have been provided by your DSL provider to prevent
interference with telephones are NOT compatible with these TMC telephones,
since these same filters will also block the data signals of the system from travel-
ing between the phones.
The solution is to have a DSL splitter (not a microfilter) installed at your network
interface. This way there will be one unfiltered line going directly to your DSL
modem, and there will be one DSL filter, with the entire TMC sytem behind this fil-
ter.
Please contact your DSL service provider or installer for details about obtaining
and installing a DSL splitter.
