|E&M (Ear and Mouth)|
Ear and Mouth is a VoIP technology which uses a conventional earpiece to receive incoming voice but uses a microphone to transmit voice across. This technology makes it easier for a PBX system to detect when a call is disconnected.
|E-AGCH: E-DCH Absolute Grant Channel|
E-DCH Absolute Grant Channel(E-AGCH) is one of the five Enhanced Dedicated Channels (E-DCH), which provides an absolute power level above the level for the DPDCH (associated with a DCH) that the UE should adopt. E-AGCH tell a UE how to regulate its transmit power level.

A form of electronic funds transfer via the Internet; several systems are now being tested.
Electronic commerce; the use of computers and electronic communications in business transactions. E-commerce may include the use of electronic data interchange (EDI), electronic money exchange, Internet advertising, Web sites, online databases, computer networks, and point-of-sale (POS) computer systems.
|E-DCH: Enhanced Dedicated Channel|
Enhanced Dedicated Channel (E-DCH) is a transport uplink channel used in the 3G technologies (such as HSUPA) to improve capacity and data throughput and reduce the delays in dedicated channels in the uplink. The maximum theoretical uplink data rate that can be achieved is 5.6 Mbps. As with HSDPA, E-DCH relies on improvements implemented both in the PHY and the MAC layer. The definition of the E-DCH introduces five new physical layer channels: E-DPDCH, E-DPCCH, E-AGCH, E-RGCH and E-HICH.
A computer virus engineer, whose job is to provide real-time elimination of computer virus infections as soon as they appear.
|E-DPCCH: E-DCH Dedicated Physical Contro|
E-DCH Dedicated Physical Control Channel (E-DPCCH) is one of the five Enhanced Dedicated Channels (E-DCH), which controls channels associated with the E-DPDCH providing information to the Node-B on how to decode the E-DPDCH.
|E-DPDCH: E-DCH Dedicated Physical Data C|
E-DCH Dedicated Physical Data Control Channel (E-DPDCH) is one of the five Enhanced Dedicated Channels (E-DCH), which is the physical channel used by E-DCH for the transmission of user data.
|E-GSM: Extended Global System for Mobile|
EGSM is an extension to the GSM900 spectrum. EGSM spectrum is 880-890 MHz paired with 925-935 MHz, which is just below the original GSM 900 band. EGSM is a small radio frequency band used in Europe to provide added network capacity for GSM 900 networks. The additional 10Mhz provides an additional 50 channels.
|E-HICH: E-DCH HARQ Acknowledgement Indic|
E-DCH HARQ Acknowledgement Indicator Channel (E-HIGH) is one of the five Enhanced Dedicated Channels (E-DCH), which is used by Node-B to send HARQ ACK/NACK messages back to the UE.
Taking a course or training via the Internet; usually the World Wide Web.
Electronic mail. A service that sends messages on computers via local or global networks.
The address that gives the source or destination of an e-mail message.
|E-RGCH: E-DCH Relative Grant Channel|
E-DCH Relative Grant Channel(E-RGCH) is one of the five Enhanced Dedicated Channels (E-DCH), which indicates to the UE whether to increase, decrease or keep unchanged the transmit power level of the E-DCH.
A scam, or fraud, perpetrated using electronic communications.
|E-TAGS: Extended Total Access Communicat|
E-TAGS is Extension of the TACS (Total Access Communications System) system through the allocation of additional radio channels.
Electronic retailers; for example, retailers who do business on the Internet.
|E-TDMA: Enhanced or exended TDMA|
Enhanced or exended TDMA (E-TDMA) is an enhanced version of TDMA which will not only serve cellular, but could provide PCN-like services within current spectrum allocations.
|E-UTRA: Evolved-UMTS Terrestrial Radio A|
Evolved-UMTS Terrestrial Radio Access (E-UTRA or EUTRA), also known as UMTS Long Term Evolution (3GPP LTE) or Evolved UMTS Terrestrial Radio Access Network (EUTRAN), is specified in the 3GPP release 8. It is a key 3G technology to ensure the competitiveness of UMTS and provide a high-data-rate, low-latency and packet-optimized system. Besides peak data rates of 100 Mbps in downlink and 50 Mbps in uplink, a significant increase in spectrum efficiency and capacity as well as a significant latency reduction are planned. Commercial aspects like costs for installing and operating the network form also part of the requirements.
An electronic magazine. Many ezines are online versions of print magazines.
E.164 is the ITU (International Telecommunication Union) administered global numbering system which describes the structure of a telephone number (a country code, a city or area code plus a phone number).
E.214 is a telephone numbering plan used for delivering mobility management related messages in GSM networks. The E.214 number derived from the IMSI E.214 numbers are composed of two parts. The first, the E.164 part, is made up of a country code followed by the network code. The second part of the number is made from the MSIN part of the IMSI which identifies an individual subscriber. For more details on the derivation of the E.214 number from the IMSI, see the article about the IMSI.
E1 telecommunication lines are similar to T1 communication lines widely used in North America. Primarilyy deployed in Europe, E1 lines consist of 30 voice channels and offer speeds up to 2.04 Mbits/sec. Businesses in Europe use E1 telecommunication lines to connect and use the Internet. The E1 interface connects to the RJ-48C connector using two pairs â?? TX and RX. Also used by VoIP networks, E1 interfaces allow communication between the VoIP IP PBX server and data channels.
E911 or Enhanced 911 allows cellular phone and VoIP callers to call 911. Besides, E911 allows tracking the position of the caller as well. A 911 call is usually routed to what is known as the Public Safety Answering Point or PSAP. In turn, the PSAP routes calls forward. Until the mid 1990s, cell phone users could not connect directly to the PSAP. However, an FCC ruling in 1996 mandated cell phone providers to route E911 calls directly to the PSAP. The FCC in 2005 also ruled that VoIP services provide users with the E911 capability. To do so, 911 calls are required to connect to the regular phone network.
