14.5 Data Access with Modem Commands
The Deskmaster may be controlled with AT commands, similiar to an analog modem. This may control
call setup and also data/file transfers with a variety of standard PC programs (such as HyperTerminal,
provided with Windows). Except for the commands “A/” and the Escape sequence “+++”, all
commands will start with the characters AT. The command A/ may be used to repeat the last
command. The maximum length of a command line contains 40 characters, including the line
separators (CR/LF). An invalid character in a command line will be ignored.
Several AT commands may be transmitted within one command line :
• ATZX1D1234<CR>
has the same effect as
• ATZ<CR>
• ATX1<CR>
• ATD1234<CR>
The AT command set of the Deskmaster has been extended by some commands. This is mainly applic-
able for voice functions.The Deskmaster will respond to most commands with a result code.
(See Appendix for a list of supported commands.)
15 DESKMASTER 520I ANALOG INTERFACE
The following functions are only available on the Deskmaster 520i.
The configuration with integrated analog interface allows additional connection of an analog terminal
after the ISDN phone, such as:
•
Analog phone;
• G3 fax;
• Cordless telephone.
- The Deskmaster with analog interface comes with an external plug. This terminal is not fed by the
communication network and therefore it is not suitable for emergency operations. Apart from
that, the phone offers the same functionality as the Deskmaster 500i and the Deskmaster 510i.
- Note that only 2 communication channels are available at the same time. This implies that a third
extension will be in a busy condition, when already 2 channels are in use (e.g. in case of a voice
call from the ISDN phone and an active fax connection, an attempt to establish an additional data
call may be rejected).
