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.

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)
