Directory Access Commands - Phone Book

This set of commands enables read/write access to the phone book contained within the G24,
including both the numeric and the alpha information contained in the location. The presentation
is according to GSM 07.07.
In some cases, it may be possible to use these commands to access the dialed and received call
stacks. However, as these phone books cannot be edited, the +CPBW command does not work on
them.

the G24’s phone books’ memory. (When there is separate storage on the SIM card and in the
G24’s internal EEPROM).
