Configiration

INSYS Modem 56k can be adjusted to the line requirements of 87 countries worldwide by 
a configuration command. The country codes for the firmware versions “standard coun-
tries” and “further countries” are listed in chapter 8. Some countries do not require a 
separate adaptation but are using the standards “TBR21 (Europe)” or “ITU/Taiwan”.  
TBR21 is the accurate setting for the countries of the European Union, Switzerland, 
Liechtenstein, Norway and Iceland. Select the explicit country code only when INSYS Mo-
dem is connected to an older private branch exchange (PBX). 
INSYS Modem 144 and 336 are configured for operation in western Europe (TBR21) only. 

When dial tone detection is active, a dial attempt without the presence of a dial tone 
being detected is aborted with the message NO DIALTONE. Without dial tone detection 
dialing is attempted and reports NO CARRIER if not successful. Dialing without dial tone 
detection is often required behind a private branch exchange (PBX). 
Attempts to call a busy line is answered by the message BUSY in both cases. 

The modem is answering incoming calls after the specified number of RING indications 
autonomously.
