Use of DTE-DCE interface for Short Message Service (SMS) and Cell Broadcast Service (CBS) 

[2]   ETSI GSM 07.07: Digital cellular telecommunications system  (Phase 2);  

AT command set for GSM Mobile Equipment (ME) 

[3]   ITU-T Recommendation V.25 ter: Serial asynchronous automatic dialing and control 

[4]   ETSI GSM 03.40: Digital cellular telecommunications system  (Phase 2);

The words, 

“Mobile Station” (MS) or “Mobile Equipment” (ME) are used for mobile terminals supporting GSM services

.

 

Terminal Equipment (TE) is the Man-Machine Interface of a GSM device (modem or handset). A TE can be a hanset 
MMI or the AT Command interface. 

A call from a GSM mobile station to the PSTN is called a 

“mobile originated call” (MOC) or “outgoing call”, and a call 

from a fixed network to a GSM mobile station is called a 

“mobile terminated call” (MTC) or “incoming call”. 

In this document, the word “product” refers to any Multi-Tech product supporting the AT commands interface.
