Programmable Telecommunications Data Filter

      A program is disclosed that processes data that is to be
transmitted by a telecommunications network.  Data is translated by
the disclosed program into a format that can be successfully
transmitted by any network.

      All data, that is presented to a telecommunications network,
must follow the data protocol that is established by the network.
The input data must consist of only the characters that can be
successfully transmitted over the network.  A network may treat a set
of predefined characters as "control characters".  Control characters
are not passed through to the receiving partner but are acted upon by
the network processor.

      The data filter program processes the input data using a set of
characters that is selected by the communicating partners.  The set
of characters is a subset of the characters that can be successfully
transmitted across the network.  Both the sending partner and the
receiving partner must use the identical set of characters when
processing the data.  The sending partner uses the program as in Fig.
1 to convert each character of input data into a pair of characters
from the user-selected set.  All characters are effectively filtered
and can be successfully transmitted over the Telecommunications
Network.

      The receiving partner must use the program as in Fig. 2 to
recover the original data from the filtered data.  Each pair of
characters from the filtered dat...
