The correct option is A ISDN is cheaper
Advantage of ISDN over PSTN is that ISDN is
cheaper.
Unlike the PSTN, the ISDN provides better voice
quality. Moreover, the ISDN provides 128 kbit/s, which is really good for the
Internet. PSTN has a disadvantage that it does not make the most possible use
of the broadband.
The basic advantage of ISDN is to facilitate the
user with multiple digital channels. ... ISDN provides high data rate because
of digital scheme which is 56kbps. ISDN network lines are able to switch
manifold devices on the single line such as faxes, computers, cash registers
credit cards readers, and many other devices.
An ISDN line is a digital line - your computer
connects to the ISDN line (via a terminal adaptor) without having to convert
the data into sound first. A basic rate ISDN line provides two 'channels', each
of which can be used for separate calls, thus equivalent to having two regular
lines.
The entry level interface to ISDN is the Basic Rate
Interface (BRI), a 128 kbit/s service delivered over a pair of standard
telephone copper wires. The 144 kbit/s payload rate is broken down into two 64
kbit/s bearer channels ('B' channels) and one 16 kbit/s signaling channel ('D'
channel or data channel).
