Maxon Telecom MM-6280IND manual References, 3GPP TS

Term	Description
MSC	Mobile Switching Centre
MT	Mobile-Terminated where the SMS or the call is terminated [received] at the
	Mobile Station.
	Mobile Termination 2An MT2 provides a non-ISDN (Rm) user interface, e.g.,
MT2	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.
	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.
TE2	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.
	Universal Asynchronous Receiver-Transmitter, the UART is a microchip
	component that handles asynchronous serial communication. Every computer
UART	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
