Channel Associated Signaling (CAS) signaling is a form of digital communication signaling. As with most telecommunication signaling methods, it uses routing information to direct the payload of voice or data to its destination. With CAS signaling, this routing information is encoded and transmitted along the same link as the payload itself. This results in lower available bandwidth for the payload, normally reducing a 64 kbit/s DS0 to 56 kbit/s. Because of this, and the inherent security benefits of separating the control lines from the payload, most current telecom systems rely more on the out-of-band signaling. See Common Channel Signaling. ...more on Wikipedia about "Channel Associated Signaling"
CIF (Common Intermediate Format) is used to standardize the horizontal and vertical resolutions in pixels of YUV sequences in video signals. QCIF means "Quarter CIF". SQCIF means "Sub-quarter CIF". These two formats are common in video encoding. To have one fourth of the area as "quarter" implies, height and width of the frame are halved. A CIF is commonly defined as one-quarter of the 'full' resolution of the video system it is intended for (listed below as 4CIF). Note that this full resolution does not match what is currently refered to as D1 video (based upon Sony's D1 format). ...more on Wikipedia about "Common Intermediate Format"

In digital telecommunications, where a single physical wire can be used to carry many simultaneous voice conversations, worldwide standards have been created and deployed. The CEPT originally standardized the E-carrier system, which revised and improved the earlier American T-carrier technology, and this has now been adopted by the ITU-T. This is now widely used in almost all countries outside USA, Canada and Japan. ...more on Wikipedia about "E-carrier"
Extended Super Frame (ESF) is a T1 framing standard. Sometimes called D5 framing. Preferred over its predecessor, Super Frame, because it includes a cyclic redundancy check (CRC) and bandwidth for a data link channel (used to pass out-of-band data between equipment). ...more on Wikipedia about "Extended Super Frame"

JAIN is an activity within the Java Community Process, developing APIs for the creation of telephony (voice and data) services. Originally, JAIN stood for Java APIs for Intelligent Network. The name was later changed to Java APIs for Integrated Networks to reflect the widening scope of the project. The JAIN activity consists of a number of "Expert Groups", each developing a single API specification. ...more on Wikipedia about "JAIN"
In telecommunication, the term open systems architecture means the layered hierarchical structure, configuration, or model of a communications or distributed data processing system that (a) enables system description, design, development, installation, operation, improvement, and maintenance to be performed at a given layer or layers in the hierarchical structure, (b) allows each layer to provide a set of accessible functions that can be controlled and used by the functions in the layer above it, (c) enables each layer to be implemented without affecting the implementation of other layers, and (d) allows the alteration of system performance by the modification of one or more layers without altering the existing equipment, procedures, and protocols at the remaining layers. ...more on Wikipedia about "Open systems architecture"

The Plesiochronous Digital Hierarchy (PDH) is a technology used in telecommunications networks to transport large quantities of data over digital transport equipment such as fibre optic and microwave radio systems. The term plesiochronous is derived from Greek plesio, meaning near, and chronos, time, and refers to the fact that PDH networks run in a state where different parts of the network are almost, but not quite perfectly, synchronised. ...more on Wikipedia about "Plesiochronous Digital Hierarchy"

The Radio Regulations is an intergovernmental treaty text of the International Telecommunication Union (ITU), the Geneva based specialised agency of the United Nations which coordinates and standardises the operation of telecommunication networks and services and advances the development of communications technology. ...more on Wikipedia about "Radio Regulations" http://www.shortopedia.com Is Good For You.
In telecommunications, a secondary frequency standard is a frequency standard that does not have inherent accuracy, and therefore must be calibrated against a primary frequency standard. ...more on Wikipedia about "Secondary frequency standard"
In telecommunications, T-carrier is the generic designator for any of several digitally multiplexed telecommunications carrier systems originally developed by Bell Labs and used in North America and Japan. ...more on Wikipedia about "T-carrier"
In telecommunication, trellis modulation (also known as trellis coded modulation, or simply TCM) is a modulation scheme which allows highly efficient transmission of information over band-limited channels such as telephone lines. Trellis modulation was invented by Gottfried Ungerboeck. ...more on Wikipedia about "Trellis modulation"
Zero-bit insertion is a bit stuffing technique used in data transmission protocols to ensure that the frame sync sequence (FSS) doesn't incidentally appear in a data frame. ...more on Wikipedia about "Zero-bit insertion"
