ADSL

ADSL (Asymmetric Digital Subscriber Line) is a form of DSL (Digital Subscriber Line) data communications technology that enables faster data transmission over copper telephone lines that that provided by a conventional dial-up or ISDN (voiceband) modem. A splitter (or microfilter) allows a single telephone connection to be used for both ADSL services and voice calls at the same time. All voice calls made on the line will be charged by the telecommunications provider at standard call rates.

ISDN

ISDN (Integrated Services Digital Network) connectivity is a faster form of dial-up access. It is a set of communication standards designed to digitally transfer voice, video, data and other network services over traditional telecommunication network infrastructure. The key feature of ISDN is that it itegrates data and voice over the same lines.

It typically provides 64 kBits/s or 128 kBits/s for both upstream and downstream connections. The performance of an ISDN connection is significantly better than that of a dial-up connection.
