Fixed-Line Telephony

[Crazed_87]

Hi All,

Any one have idea/clues on what types of Fixed-Line Telephony are there?

I presume it something to do with PBX/ISDN for a WAN to use multiple phones and extension.

There is limited information online or I might have got the name wrong, please let me know.

Thanks.

I'm talking about the phone line used for one line and multiple extensions within a branch etc.
