[ Figure 4 ] Operation Image for “Type3 Serial Operation” in DSP mode
5.2 Operatable Functions
Outline of operatable functions in each mode is mentioned in [ Table 14 ].
In DSP mode, Type 3 command control (*) is used for modem operation. During this
period, serial interface is not operatable. Also, “Error correction” and “Data Compression”
functions such as V.42/V.42bis, MNP is not supported in Data communication.

5.3 Usage for Type 3 Serial Mode
For FAX communication, the detail parameter setting is required and Type 3 command control
is suitable to use. Also, for DATA communication, AT command control is popular to use.
Therefore, it is
the best suited for both FAX and DATA communication by connecting
MN195007 to Host CPU with DSP mode and operating with Type 3 serial mode.
