| The FAX4100 directly interfaces to any standard "Group-III" (G3)
telephone FAX machine. We provide ring signal, off-hook loop
current, dial tone, and DTMF tone decoding. At the start of each
FAX connection, the FAX4100's internal FAX modem negotiates data
rate and other communications parameters with your FAX machine. On
the radio modem side, the FAX4100 includes the normal link and
control commands used by the HAL DSP-4100/2K modem. When you
initiate a FAX transmission, the FAX4100 decodes the dialed
number, sends it to the DSP-4100/2K as a call sign, and instructs
the DSP-4100/2K to start CLOVER-2000 ARQ link procedures. Once a
satisfactory ARQ link is established, data from the FAX machine is
passed to the modem for transmission via radio. It's one efficient
and integrated system. |
