How do I install Internet using an isdn connection?

Broadband Internet access, often shortened to "broadband Internet" or just "broadband", is a high data-transmission rate internet connection. DSL and cable modem, both popular consumer broadband technologies, are typically capable of transmitting faster than dial-up modem (56 kilobits per second). The real maximum download speed of a dial-up modem is only about 48 Kilobits/second, and upload speed is even slower (31.2kb/sec for V.90, 44kb/sec for V.92).
