E
- E1
- Abbreviation for the European equivalent of DS1 (T1) (ITU-T
Rec. G.703 and G.732), 2.048 Mbps.
- E3
- Abbreviation for the European equivalent of DS3, 34.368
Mbps.
- EBU
- European Broadcasting Union. Headquartered in Geneva CH and
with its technical center in Brussels BE, the EBU is an association of European
and world broadcasters, including the Eurovision Network. The EBU provides regulatory, legal and technical services, as well as programming to its members.
- Echo Return Loss Enhancement (ERLE)
- A figure of merit for acoustic and telephony echo cancellers,
expressed in dB. An echo canceller electronically enhances the
apparent loss between tends of a telecommunications circuit (TEC) or between the room loudspeaker and the microphones (AEC).
- Echo Suppression
- The insertion of mild attenuation in audio transmit and/or receive signal path to eliminate howling caused by excessive closed-loop gain. Echo suppression may also be used with TECs and AECs to attenuate any residual echo signals.
- EEPROM
- Electrically-Erasable Programmable Read-Only Memory. A non-volatile but electrically alterable form of semiconductor storage. These devices are present in some telecommunications equipment such as codecs, permitting long-term storage of configuration, dialing and related information
for easy recall by the user. A fast, reliable EEPROM version is popularly known as FLASH memory.
- EIA
- Electronic Industries Association. A North American standards-setting body.
- Encryption
- One of a number of approaches to convert "plain
text" or data into information that is unreadable except by the intended
recipients. Adjectives like "weak" and "strong" are often
used to further describe the encryption systems. Similarly, under government or military
applications, encryption may be described as providing "privacy" or
"secrecy".
- EPROM
- Electrically Programmable Read-Only Memory. A non-volatile,
electrically-write-once semiconductor storage device, useful for storage of
parameters which normally do not need updating during the life of the product
or system.
- ESF
- Extended Superframe Format. A network control and framing
method used by common carriers that incorporates control and information data
in the transmitted bit stream. When connecting networks and equipment, it is
important that both the equipment and the network support the same appropriate
protocols.
- ETSI
- European Telecommunications Standards Institute
