At^sdld Delete The 'Last Number Redial' Memory - Multi-Tech MultiModem EDGE Reference Manual

<nlength>
Maximum length of phone number for "normal" locations. Depending on the storage, a limited number of
locations with extended memory is available per phonebook. These locations allow storing numbers with twice
the standard length, which is 2*<nlength> digits for normal numbers, but only <nlength> digits for numbers saved
with parameter <type>= 209. If all extended locations of the selected phonebook are used up, then any attempt
to write a number which requires extended memory will be denied with CME ERROR 260: INVALID DIAL
STRING.
<tlength>
Maximum length of <text> assigned to the telephone number. The value indicated by the test command is given
in octets. If the <text> string is given in GSM characters, each character corresponds to one octet. If the <text>
string is given in UCS2, the maximum number of characters depends on the coding scheme used for the alpha
field of the SIM. In the worst case the number of UCS2 characters is at least one less than half the number of
GSM characters.

Examples
Example 1
Make a new phonebook entry at the first free location (here location 3)
AT^SPBW=,"+431234567",145,"international"
^SPBW: 3
Example 2
Delete entry at location 3
AT^SPBW=3
Example 3
The following examples are provided to illustrate the effect of writing phonebook entries with different
types of dial string modifiers in <number>.
AT^SPBW=5,"12345678",,"Arthur"
^SPBW: 5
AT^SPBW=6,"432!+-765()&54*654#",,"John"
^SPBW: 6

^SPBW: 8
AT^SPBW=9,"432!+-765()&54*654#",209,"Richard"
^SPBW: 9
Example 4
