INTERNET ACCESS ROUTER

Frame Relay is a network interface that provides high-speed frame or packet

transmission with minimum delay and maximum use of bandwidth.

PSTN (Public Switched Telephone Network) is the telecommunications

network commonly accessed by telephones, key systems, private telephone
exchanges, and data equipment. Access can be via regular switched circuits,
or dedicated leased lines.

DDS (Digital Data Service)—Digital leased lines that support transmission

rates between 2.4 and 56 Kbps.
