DSL vs ISDN ConnectionDSL, or Digital Subscriber Line, make use of existing telephone lines to transfer data to users at high speeds - as much as 100 times faster than standard analog modems. With the help of DSL, all websites which usually takes minutes to download through a dial-up connection can be downloaded in seconds. In addition to this, huge files can be delivered in seconds, and bandwidth-hogging applications such as online meetings and video cams work efficiently. ISDN ConnectionISDN, or Integrated Services Digital Network, on the other hand uses phone lines in use to deliver data, voice and fax transmissions over the same phone line. Till the time DSL was introduced, ISDN was considered as the least expensive option for small and medium-sized companies to get a fast digital connection to the internet or a corporate Local Area Network (LAN).

ISDN connection transfers at speed up to 128 kbps, considerably faster than a dial-up modem connection

DSL vs ISDNThe DSL vs ISDN table given below highlights key differences between both the technologies :DSL vs ISDN Connection

As shown in the DSL vs ISDN table above, DSL main advantage over ISDN is even the slowest DSL connection is still faster than any ISDN connection available. In addition, since DSL is "always on," there are no per-minute charges. With a number of speed options from 144 kbps to 1.5 mbps - and faster dsl connection options coming in the near future

fulfills all your requirements.
