Digital cellular communications equipment must default to using error correction on the radio link. For example, for GSM 7.07, the modem must initialize to +CBST=,,1 (which selects a “nontransparent” air interface).
To allow data cards to use GSM/ISDN V.110 “fast access” where available in the network, +CBST=71,, ( 9600 bits per second (bps) V.110) must be a valid setting.
B6.1.4.2.3.5 If SMS support is implemented, the modem supports appropriate +C SMS control commands
To allow software applications to specify settings and manipulate short messaging services (SMS) through a GSM modem card, the card must support the following GSM 07.05 commands:
