Switched Multimegabit Data Service
SMDS, communications network based on data packet switching (designed to serve as a foundation for data networks in telephone companies)
Switched multimegabit data service
Switched Multimegabit Data Service (SMDS) is a telecommunications service that provides connectionless, high- performance, packet-switched
data transport. Being neither a protocol nor a technology, it supports standard protocols and communications interfaces using current (and future) technology. SMDS allows users to transparently extend their data communications capabilities over a wider geographical area. Since it is a SERVICE offered by the telephone companies, SMDS permits this expansion using existing
Customer-premises equipment (CPE) and protocols, with minimal investment in dedicated leased lines as the number of line terminations increases.
