Definitions
Integrated Services Digital Network (ISDN): ISDN is a digital transmission system, which is used to transmit voice and data through copper telephone wires. In other words, it's a circuit-switched data transmission system that is used for voice and data transmission over the wire.
Digital Subscriber Line (DSL): DSL is also a digital transmission system and utilizes already installed copper wires to send voice and data packets.
Differences
As far as the differences between ISDN and DSL transmission system are concerned, there are several differences one can find:
Speed
In terms of speed, DSL is faster than ISDN. DSL sends data packets with speeds ranging from 128Kbps to over 100 Mbps using latest DSL standards such as VDSLv2. On the other hand, ISDN comes in two different speeds i.e., 64Kbps and 128Kbps.
