FIGURE 2
EXTERNAL DATA STORAGE
This section describes in detail the names and definition of the parameters which de-
fine the Tone Plan for a PABX. Values for these parameters are selected by the system
designer in accordance with the relevant standards and are saved in an external EPROM
to be addressed by the SA9401.
Reference can be made to the diagram of fig. 3 which defines the memory map of the
EPROM.
