NB:
The Number Assignment Module (NAM) is programmed through the telephone keypad. There are two NAM-programming modes available; the short and the 
long. The short programming mode is all that is required in most cases. The long programming mode is required if a value set by the short mode is not desired.Either mode may be used stand-alone, or the short mode can be used to set up most of the values and then the long mode can be used to make any changes desired. To enter either of the two NAM programming modes, press and hold down the FCN key while entering a specific series of digits. You must enter the digits within ten seconds.
