Answer:
Following are the solution to the given points:
Step-by-step explanation:
For point 1:
Integrated Communications Networks is a technology used to transmit digital signals using telephone lines cables over a local loop.
Due to its larger capacity, it's far faster than just a 's got. ISDN Basic Rate Service (BRI) offers a total bandwidth of 144 kpbs, which would be based on two B channels and a 16 Kbps D channel. As private and small company customers, however, it is adequate.
The BRI is split into two categories: a) in-house cable from the ISDN end to the NT (S/T reference or S-bus) and b) broadcast from the NT to a headquarter (U reference point).
It enables a full-duplex operating point.
This BRI section's maximum length is between 4 to 8 km.
You pay for the speed you utilize using an ask service. In all other words, the price cost of how long you remain connected was evaluated. One can also buy flat-rate usage plans because you can with the phone service.
Given the fact ISDN uses an existing Cat 3 cable, re-connection to a service is not necessary.
In regions in which no additional high-speed access to the internet is available, ISDN can be available.
For point 2:
In the BRI configuration, 2 Data (bearer) lines with 64 kbit/s are available. With voice and user information the B-channels have been used.
For point 3:
Yes, It offers concurrent voice & data communications with improved signaling capacity at 64 kb/s.
For point 4:
It is true.
