Carrier Grade Linux

Index Carrier Grade Linux

Carrier Grade Linux (CGL) is a set of specifications which detail standards of availability, scalability, manageability, and service response characteristics which must be met in order for Linux kernel-based operating system to be considered "carrier grade" (i.e. ready for use within the telecommunications industry).

Media gateway

A media gateway is a translation device or service that converts media streams between disparate telecommunications technologies such as POTS, SS7, Next Generation Networks (2G, 2.5G and 3G radio access networks) or private branch exchange (PBX) systems.

Open Source Development Labs

Open Source Development Labs (OSDL) was a non-profit organization supported by a global consortium tasked to "accelerate the deployment of Linux for enterprise computing." Founded in 2000, its goals included "to be the recognized center-of-gravity for the Linux industry." OSDL positioned itself as the "industry's first independent, non-profit lab for developers who are adding enterprise capabilities to Linux." The headquarters was first incorporated in San Francisco but later relocated to Beaverton in Oregon with second facility in Yokohama, Japan.

Time-division multiplexing

Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern.
