Is ATM a Broadband Transmission?

[Vengence]

Trying to determine if A.T.M. uses Broadband or Baseband transmission. Anyone?

[C.M. Weaver]

Baseband: Where only 1 carrier frequency is used.
Broadband: Multiplexes multiple independent signals onto one cable.

ATM (Asynchronous Transfer Mode) is a broadband technology because it multiplexes independent signals onto one cable.

Good point. What confuses me though... Broadband is Multiplexed signals using varying frequencies to be transmitted together. A.T.M. can and often does use Fiber Optic Cable which is a baseband only transmition. So if A.T.M. is broadband, how does it use baseband media?

Just because something runs over fiber does not mean that it is baseband. Fiber has a large amout of bandwidth that is unused do to the lack of technology in multiplexing. You can combine multiple frequencies to get the combined data stream for higher rates of communication.
