What is the difference between ISDN connection and a dial up connection using PSTN/POTS(normal telephone connection which uses analog technology in local loop) for Internet access?
1)Both service provider(ISDN and POTS) promises a bandwidth of 144 kbps.The desired answer is expected only in terms of effective bandwidth that we recieve and not the advantages of ISDN like several connections can be made simultaneously etc.
2)Is higher cost of ISDN connectivity justified? How in terms of effective bandwidth?
Thanks in advance
