060R122-000 SpectraComm Dual V.34 Modem 3-23
Issue 15 Installation and Operation
Configuration Profiles
A configuration profile consists of the set of AT commands the modem is given to establish its
operating characteristics. The modem can store four factory-provided fixed profiles and four user
defined profiles. By recalling and loading a stored profile you can completely reconfigure the
modem without having to change individual options. The individual profiles in each of the two sets
are identified as
0 - 3
.
• Use the
&F
n command to recall and load one of the four Fixed Profiles
(See Table 4-1 for specific settings in each.)
• Use the
&W
n command to store a user-defined User Profile. When the modem receives the
&W
n
command, it stores the configuration options in effect at that time as User Profile n.
• Use the
Z
n command to recall and load a user-defined User Profiles.
• Use the
&Y
n command to specify which of the four User Profiles will be activated when the
modem powers up.
Each time its power is turned On the modem recalls and loads a user defined profile. You specify
which of the four user defined profiles it will use for that purpose by means of the Power Up User
Configuration Profile command,
&Y
n. When the modem leaves the factory the initial default
setting for
&Y
n is user defined profile
0
. The factory default for user profile
0
is the same as
fixed profile 0 .
Remote Configuration Using the AT Commands
Remote Configuration allows you to use the local modem to connect to a remote modem, and view
or change the remote modem's user configuration profile. The DTE interface on the remote modem
is disabled during a Remote Configuration session to prevent the remote DTE from inadvertently
terminating the session.
Remote Configuration Requirements
Before starting a Remote Configuration session, you must ensure the following:
• Modems must either both be in switched network mode or both be in private line mode.
• The local modem must be in AT command mode (
%V0
or
PRS AT
command). The remote
modem will be forced into AT command mode when the connection is established.
• The local modem must be in an asynchronous error correcting mode. The remote modem will
be forced into asynchronous mode when the connection is established.
• Both modems must have the same remote configuration security password (
*P
n command). If
the remote modem does not, you can configure one during the Remote Configuration session.
• The remote modem's handshake mode must be V.34 (
&H0
,
&H1
, or
&P0
command),
V.32 bis (
&H2
,
&H3
, or
&P1
command), or V.32 (
&H4
,
&H5
, or
&P2
command).
• Remote configuration write access must be enabled at the remote modem via the
*R0
command in order to edit/save configuration changes.
Note
When configuration profiles are loaded in the modem, modem parameters set by the following commands
are not affected :
%F , H , %P , *R , &V , %V , &W , %W , *W , *X , %X1 , Zn , &Z .
Note
Refer to Chapter 4, AT Command Set Operation for description of all AT commands, including profile
commands:
&F n, Z n and &W n.
