Term Description
MSC Mobile Switching Centre
MT
Mobile-Terminated where the SMS or the call is terminated [received] at the
Mobile Station.
MT2
Mobile Termination 2An MT2 provides a non-ISDN (Rm) user interface, e.g.,
CCITT V series or CCITT X series. Same at DCE. Refers to the MM-6280IND
modem.
NVM
Non Volatile Memory. User changeable and is written at time of change or
entry to a separate section of memory unaffected by power cycles. The setting
value is available in all profiles.
PCCA Portable Computer and Communications Association
Rm Hardwire Interface between MT2 and TE2.
SMS Short text Message Service.
TE2
Terminal Equipment 2. A TE2 is a data terminal device that has a non-ISDN
user-network interface, e.g., CCITT V series or CCITT X series. Same as DTE.
Products which can issue AT command set and handle the response through
UART or RS-232 signalling ports of the MM-6280IND. The popular examples
of MT2 are PC’s, PDA and embedded systems i.e. Data Logger, PLC etc.
UART
Universal Asynchronous Receiver-Transmitter, the UART is a microchip
component that handles asynchronous serial communication. Every computer
contains a UART to manage the serial ports, and some internal modems such
as MM-6280IND have their own UART. UART 1(RS232 port) UART 2 (On
serial for diagnostics)
UE User Equipment
UI User Interface.
UICC Universal Integrated Circuit Card
Um Over-air interface between the MT2 and the BS.
USIM Universal Subscriber Identity Module
