provides telephony and Dual Tone Multi Frequency (DTMF)
transmission functionality. It also allows for emergency calls
as well as echo cancellation and noise reduction (option),
and full rate, enhanced Full Rate and Half Rate (FR/EFR/HR).
Compatible Supplementary Services. The MultiModem GPRS
cellular modem is compatible with supplementary services
such as call forwarding, call barring, multiparty, call waiting
and call hold, calling line identification, advice of charge,
USSD, closed user group and explicit call transfer.
