You are probably missing a DSL Line Filter on one or more phones.
No, DSL can use the same phone line as your house phone. The reason for this is that DSL operates in a different frequency band than normal phone transmissions.
when the phone rings if my phone rings, i will answer it!
Quest and Verizon also provide local phone service with DSL.
Use a 1 to 2 phone jack splitter and then a filter on your DSL jack.
the phone equipment (substation, etc) must be DSL compatible. If not, you can't get DSL. DSL is also limited to distance which is about 18,000 feet from the CO.
You need a DSL line and a DSL modem for a home connection. Contact your local phone company or ISP for a connection.
From what I've read, it seems that AT&T phone service is included in the DSL service. Because it is attached to the phone lines, the phone comes with it. I think that if you talk to customer service, they may be able to bypass the phone service so that you can only get DSL.
Try to install the DSL filter coming out of your phone.
Do you have a DSL and HOME phone service combination?
to do that you will need the DSL filter first. The phone cord needs to plug into one end of the filter box, while a cable goes from the filter box to the DSL port in the wall.
If you're talking about mobile broadband for your phone, it's neither DSL nor T1: it's 3G.
Most POS machines these days can still use phone connections but also accept DSL.
