EFS
Error Free Seconds: A unit used to specify the error performance of T carrier systems, usually expressed as EFS per hour, day, or week. This method gives a better indication of the distribution of bit errors than a simple bit error rate (BER). Also refer to SES.
ELAN
Emulated Local Area Network: A logical network initiated by using the mechanisms defined by LAN Emulation. This could include ATM and legacy attached end stations.
EMA
Emergency Controller
EMI
Electromagnetic Interference: Equipment used in high speed data systems, including ATM, that generate and transmit many signals in the radio frequency portion of the electromagnetic spectrum. Interference to other equipment or radio services may result if sufficient power from these signals escape the equipment enclosures or transmission media. National and international regulatory agencies (FCC, CISPR, etc.) set limits for these emissions. Class A is for industrial use and Class B is for residential use.
EMI/RFI
ElectroMagnetic Interface/Radio Frequency Interface: A circuit or device containing series inductive (load bearing) and parallel capacitive
EML
Element Management Layer: An abstraction of the functions provided by systems that manage each network element on an individual basis.
EMS
Element Management System: A management system that provides functions at the element Management Layer.
EOM
End of Message: An indicator used in the AAL that identifies the last ATM cell containing information from a data packet that has been segmented.
