Broad band ISDN consists of -
Broad band ISDN consists of -
The correct option is D All of the above
Broad band ISDN:-
Integrated services digital
network (ISDN) is a set of communication standards for
simultaneous digital transmissionof voice, video,
data, and other network services over the traditional circuits of thepublic switched telephone network.
1) Broad band ISDN consists of
the physical layer:-
The physical layer of B-ISDN can have several
different forms but its essential purpose is to collect and organize ATM cells
sent down from the ATM layer, transport them to the physical medium and also
perform the reverse of the process.
2) Broad band ISDN consists of
the asynchronous transfer mode:-
Asynchronous transfer mode
(ATM) is an international telecommunication union-telecommunications standards
section (ITU-T) standard for cell relay wherein information for multiple
service types, such as voice, video, or data, is conveyed in small, fixed-size
cells.
