NOTE: If your DSL service provider cannot supply a DSL splitter, it is
possible to purchase an outdoor DSL splitter (such as a Corning or Allen
Tel brand DSL splitter) over the Internet.
If you are a new DSL customer, your DSL service provider will likely ask you
if you have more than one telephone line in your home or business. If you
answer yes, your DSL service provider will probably advise you that you need
a splitter. Your DSL service provider may also ask if you are installing a phone
system. If you answer yes, your DSL service provider will most likely advise
you that you need a splitter. In most cases, your DSL service provider will
supply you with the proper splitter for your specific situation. The DSL
splitter, installed properly and in conjunction with a Z800A filter, should 
help overcome any interference between the DSL signal and the signals 
sent by your phone system.
AT&T shall not be responsible for the cost of installation, any damages, lost
business, direct or indirect expenses accrued or associated with installation,
or other compatibility issues which may arise as a result of using this product
while you subscribe to DSL service.
