DTMF

Dual-Tone Multi Frequency (or “touch-

 

tone”) is a method used to communicate

 

keys pressed on the phone. Pressing a

 

key generates two simultaneous tones,

 

one for the row and one for the column

 

to determine which key was pressed.

EMS

Enhanced Messaging Service is an

 

extension to SMS for cellular phones

 

available on specific networks. An EMS

 

enabled phone can send and receive

 

messages with special text formatting

 

(such as bold or italic), animations,

 

pictures, icons, sound effects, and

 

special ring tones. EMS messages sent

 

to non-EMS devices will be displayed as

 

SMS transmissions.

ERI

Enhanced Roaming Indicator is a feature

 

to indicate whether a mobile phone is on

 

its home system, a partner network, or a

 

roaming network. Many phones indicate

 

home vs. roaming as an icon, but ERI

 

capable phones can clearly indicate

 

third “partner network” status.

GPS

Global Positioning System is a system of

 

satellites, computers, and receivers able

 

to determine the latitude and longitude

 

of a specific receiver on Earth. Position

 

is calculated using time and distance.

IS 2000

Type of digital signaling. It's the second

 

generation of CDMA digital cellular, an

 

extension of IS-95. Differences between

 

signaling types have to do with pilot

 

signal and links to provide more traffic

 

channels, and control protocols.

NAM

Number Assignment Module is how the

 

phone stores the phone number and its

 

electronic serial number. A multiple

 

NAM phone can register with multiple

 

service providers and be set to

 

automatically switch between

 

programmed phone numbers for service

 

provider areas.

SID

System Identification is a number

 

transmitted by base stations to identify a

 

wireless system which conforms to a

 

TIA cellular or PCS standard.
