4 Configuring the POCKET ISDN-TA
The settings of the POCKET ISDN-TA for the V.24 interface and the S
0
interface are
called configuration. The POCKET ISDN-TA is delivered with a set of pre-set values.
In the following section it will be shown how, by using the configuration
commands, you can examine the configuration of the POCKET ISDN-TA and if
necessary change it. The values can be stored in non volatile memory; this means
they´ll remain unchanged even if the power supply is disconnected.
You can configure the POCKET ISDN-TA in the following ways:
• by using the AT command set entered by the locally connected PC.
• by using TA configuration commands entered by the locally connected PC.
• by using TA configuration commands entered via the ISDN line (remote
configuration).
Normally the configuration via AT commands is sufficient.
The latter case are for more sophisticated configuration and described in the
chapter TA+Configurator command set
4.1 AT command set
All parameter can be changed by using an extended AT command set described
in this chapter.
Please check if the factory setting will fit with your environment. The factory setting
is described (highlighted) in the parameter list shown in chapter "AT command set"
(see below).
If you want another configuration as set in the factory default setting, please do
the following steps:
• Connect the POCKET ISDN-TA to ISDN interface
• Connect the PC s com-port to the DTE interface of the POCKET ISDN-TA.
• Connect the power supply to the mains socket.
• Start a terminal emulation on your PC, please verify that the baudrate
setting of the terminal emulation fits those of the POCKET ISDN-TA.
• Set up the parameter of the POCKET ISDN-TA from the terminal emulation
and save the parameter using the AT command set.
Example:
To change the used B channel protocol to X.75 please enter the
following commands:
ATB10 < ↵ > (set protocol to X.75)
AT&W < ↵ > (save the new configuration)
• Leave your terminal emulation and start your application program.
With the exception of the command
A/ (Repeat command) all commands begin
