1.4.3 Comparison to DSL-ISDN

• 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.
