There are two significant differences between ISDN and DSL. • DSL is Faster: ISDN provides two voice/data channels, each at speeds of 64 Kbps, while DSL is predominantly a data service providing up to 1.5 Mbps downstream and up to 512 kbps upstream. Business DSL offers T1-like speeds of up to 1.5 Mbps-more than 10 times faster than ISDN! • DSL is “always on”: ISDN is a dial-up service (like a regular telephone line) that’s digital and carries both data and voice; Business DSL is “always connected” and carries data only.
