A p p e n d i x B Glossary 10/100Base-T. A physical media that can operate as 10Base-T or 100Base-T. 10Base-T. A physical media specified by the IEEE 802.3 standard for supporting Ethernet with a maximum transmission rate of 10 Mb/s. 10BaseT consists of copper twisted-pair cable normally used for wiring ordinary telephones. - Page 52 Jitter. Jitter is the deviation in some aspect of the pulses in a high-frequency digital signal or the period frequency displacement of the signal from its ideal location. The MX250 utilizes Jitter Buffers to compensate for jitter.
- Page 53 Local Area Network (LAN). A group of computers and associated devices that share a common communications line and the resources of a single processor or server within a limited geographic area, such as an office building. 10BaseT Ethernet is the most commonly used form of LAN. A hardware device called a hub serves as the common wiring point, enabling data to be sent from one machine to another over the network.
- Page 54 MX250 Hardware Manual Repeater. A device that receives a digital signal on a transmission medium and regenerates the signal for the next leg of the medium. Repeaters overcome attenuation losses caused by free-space electromagnetic-field divergence or cable loss over electromagnetic media. A series of repeaters facilitates the extension of a signal over long distances.
- Page 55 System Controller (SC). One of the boards inside the MX20. It is connected to a hard disc that stores all of the application software for the MX250 and upon power on, forwards the software to the other boards in the system. This board also has the console port directly connected to it so that you can always communicate with the system.
- Page 56 Also referred to as a location or address, URLs specify the location of files on servers. A general URL has the syntax protocol://address. For example, http://www.zultys.org/index.html specifies that the protocol is http and the address is www.zultys.org/ index.html. Unshielded Twisted Pair (UTP). Also known as 10BaseT. This is the standard cabling used for telephone lines.
