Non-Volatile Memory The U-336E has an amount of memory set aside for storing user information such as frequently used phone numbers and default command settings. The latter is particularly useful when using your modem to call a variety of different locations that require different settings. For this reason, your modem provides a number of user "Profiles" that can be accessed through simple AT commands. This section covers the topics of storing phone numbers, and saving default settings in the power-on profile. Storing Phone Numbers The AT command to store a phone number is in the format AT&Zs=n. The 's' is a number from 0 to 49 that represents the location in memory that the phone number is to be stored, and the 'n' is the phone number itself. Example: To store the number '1-714-555-1212' in memory location '2', type: AT&Z2=17145551212 You can store up to 50 telephone numbers. ONOTE: Dialing Stored Phone Numbers The AT command syntax used to dial a stored number is ATDS=n. The 'n' is the memory location of the stored number you want to dial. AS A GENERAL RULE, WHEN A LETTER IN AN AT COMMAND DEFINITION IS SHOWN IN ITALIC TYPE, THE LETTER IS NOT TO BE ENTERED AS PART OF THE COMMAND, BUT RATHER IS REPRESENTATIVE OF A NUMBER OR STRING EXPECTED AS INPUT. FOR EXAMPLE: THE LETTER 'S' IN THE ATDS=N COMMAND IS ACTUALLY TYPED, UNLIKE THE 'S' IN THE AT&ZS=N COMMAND WHICH REPRESENTS A NUMBER. Basic Modem Operation 21

Basic Modem Operation

Non-Volatile Memory
The U-336E has an amount of memory set aside for storing user
information such as frequently used phone numbers and default
command settings. The latter is particularly useful when using your
modem to call a variety of different locations that require different
settings. For this reason, your modem provides a number of user
“Profiles” that can be accessed through simple AT commands. This
section covers the topics of storing phone numbers, and saving
default settings in the power-on profile.
Storing Phone Numbers
The AT command to store a phone number is in the format
AT&Z
s
=
n
.
The ‘
s
’ is a number from 0 to 49 that represents the location in
memory that the phone number is to be stored, and the ‘
n
’ is the
phone number itself.
Example: To store the number ‘1-714-555-1212’ in memory
location ‘2’, type:
AT&Z2=17145551212<Enter>
You can store up to 50 telephone numbers.
Dialing Stored Phone Numbers
The AT command syntax used to dial a stored number is
ATDS=
n
.
The ‘
n
’ is the memory location of the stored number you want to
dial.
