Hello.

If most phone and fax machine phone jacks only need 1 pair of wires. Why do all the phone jacks have 2 pair of wires?

What is the point on the extra pair of wires?

Do the Samsung keyset phone need 2 pairs but the analog lines for Fax machines and modems only need 1 pair?

Is this something you would use only is you are using DSL connection with simutaneous use of a phone?

Thanks.
