Intermediate Distribution Frame (IDF)
Short for intermediate distribution frame, a cable rack that interconnects and manages the telecommunications wiring between an MDF and workstation devices. Cables entering a building run through a centralized MDF, then each individual IDF and then on to specific workstations. For example, an enterprise that encompasses a building with several floors may have one MDF on the first floor and one IDF on each of the floors that is connected to the MDF.

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 […]
- IDSL
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 […]
