Configurations and Data Rates
Data Encoding
Blacklisting applies separately to each number dialed, and indicates the call block-
ing capability for specific phone numbers. To minimize RAM, calls are treated as if
they are all to the same number.
The first connection attempt after modem reset or a successful connection is
always allowed. If a connection attempt is not successful, then each following con-
nection attempt is checked as follows:
The following Blacklisting parameters can be controlled through Diplomat
The Z02215 can be configured to any of the V.22bis operation modes. Table 9
provides the selectable options, the supported data rate, and the baud rate, and
frequency to be modulated.
The data encoding for the Z02215 meets ITU–T recommendations as well as Bell
standards.
