ISDN stands for Integrated Services Digital Network. Your telephone company must install this special phone line before you can enjoy ISDN's speed and reliability. What you'll pay for this phone line depends on whether you're served by GTE, Ameritech, Sprint, or KMC Telecom. A SkyeNet Network Connection connects your entire computer network via an ISDN router. The router is configured to connect only when needed, and disconnect when not in use to minimize telephone company charges and enhance security.
Customer is responsible for any telephone company surcharges for ISDN circuit use.
