+// Multimode TSY Phone book Implementation file.
+// This file contains the implementation of the CATPhoneBookInfo class, which is used

+// This class does all three AT+CPBS commands and an AT+CPBR:
+// AT+CPBS=? to get the supported storage types;
+// AT+CPBS=<storage> to set the storage type;
+// AT+CPBS? to get the 'used' and 'total' slots;
+// AT+CPBR=? to get the maximum length of the number and text fields;
+// A TPhoneBookInfo struct containing all the relevant information about the 
+// specified phone book is returned.
