Circuit switching
Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate.

Packet switching
Packet switching is a method of grouping data which is transmitted over a digital network into packets which are made of a header and a payload.
New!!: H.248 and Packet switching · See more »
Public switched telephone network
The public switched telephone network (PSTN) is the aggregate of the world's circuit-switched telephone networks that are operated by national, regional, or local telephony operators, providing infrastructure and services for public telecommunication.
