1.4.3 Comparison to DSL-ISDN

May 16, 2012 Internet Tutorials

In terms of speed, DSL is a better choice. It comes in scalable technology with speeds ranging from 128Kbps to 1.5 Mbps, while ISDN generally come in two flavors 64Kbps and 128 Kbps.
DSL utilizes the copper wiring already installed into business and homes,
ISDN also utilizes copper wiring, but a special ISDN line must be installed at customer’s location.
ISDN charges may vary depending upon whether or not the customer requires a dedicated, “always on” connection. Dedicated connections can get pricey as many ISDN packages are billed at per-minute cost. Special “dial-up ISDN” packages are available in most areas at a much-lower cost and can be a reasonable alternative in areas where DSL is not yet available.
