Digital Subscriber Line. Public network technology that delivers high bandwidth over conventional copper wiring at limited distances. There are four types of DSL: ADSL, HDSL, SDSL, and VDSL. All are provisioned via modem pairs, with one modem at the central office, and the other located at the subscriber site.

E

EMI

ESD

Electromagnetic interference. The interference by electromagnetic signals that can cause reduced data integrity and increased error rates on transmission channels.

Electrostatic discharge. A transfer of electrostatic charge between bodies of different electrostatic potentials, such as an operator and a piece of electrical equipment. ESD occurs when electronic components are improperly handled. ESD can damage equipment and impair electrical circuitry. ESD is more likely to occur with the combination of synthetic fibers and dry atmosphere.

F

Flash memory
