My unit is the broadband of the radio and television, why do we still have to dial up when we go online, but also have not seen the cat, is a network cable directly to the computer?

Broadband broadband program is FTTH/FTTB (Fiber to the Home/Building), more than the ordinary AD but also ahead of the curve, of course, this type of program is often based on technology for the xPON technology. Among them, placed on the client side of the AOLYNKET equipment called optical network unit (ONU: Optical NetworkUnit, simply put is the fiber - Ethernet electrical port conversion), is required and the bureau end of the fiber optic switch with the use of pairs.

So, for the client, is actually directly connected to the Ethernet, but the "Ethernet switch" is placed on the local end only.

Generally speaking, in the first connection will automatically go to the authentication WEB, enter the account password for authentication, of course, there are also through the preset port / IP address / MAC address and other means to skip the authentication.
