Short for Integrated Digital Network Exchange, a technology that multiplexes voice, data, and video onto multiple T1/E1 backbones. Allowing integration of equipment from different vendors, IDNX is an integrated packet/circuit switch providing frame-relay adaption for X.25 packet switches, SNA communications processors and other HDLC-based devices. IDNX concentrates and routes this traffic along with Ethernet and token-ring LAN-generated frame-relay frames, over private or public frame-relay networks. IDNX also supports voice/fax compression, ISDN and switched 56K/64K call setup, and digital cross-connection.
The IDNX family has been functionally superseded by the Promina family of ATM switching platforms, and in particular the Promina 800 Series Multiservice Access Platform that provides an enhanced chassis and bus system to the IDNX while being able to make use of IDNX modules.
Short for ISDN Digital Subscriber Line, a method of providing DSL technology over existing ISDN lines. Even though the transfer rates for IDSL are about the same as ISDN (144kbps v. 128kbps), and IDSL circuits typically only carry data (not voice), the major benefits of switching to IDSL from ISDN are always-on connections, thus eliminating […]
- IEEE 1394
A very fast external bus standard that supports data transfer rates of up to 400Mbps (in 1394a) and 800Mbps (in 1394b). Products supporting the 1394 standard go under different names, depending on the company. Apple, which originally developed the technology, uses the trademarked name FireWire. Other companies use other names, such as i.link and Lynx,to […]
Abbreviation of Institute of Electrical and Electronics Engineers, pronounced I-triple-E. Founded in 1884 as the AIEE, the IEEE was formed in 1963 when AIEE merged with IRE. IEEE is an organization composed of engineers, scientists, and students. The IEEE is best known for developing standards for the computer and electronics industry. In particular, the IEEE […]
- IEEE 802 Standards
A set of network standards developed by the IEEE. They include: IEEE 802.1: Standards related to network management. IEEE 802.2: General standard for the data link layer in the OSI Reference Model. The IEEE divides this layer into two sublayers — the logical link control (LLC) layer and the media access control (MAC) layer.The MAC […]
- IEEE 829
(pronounced as separate letters) An IEEE standard for documenting the testing of software. The standard typically applies to any stage in the testing of developing software, and each stage in the software’s development typically is documented using the same application of the standard. The IEEE specifies eight stages in the documentation process, each stage producing […]
