Interphase Tech 5536 Manuel D’Utilisation

If the 5536 Digital Modem RAS Support driver is installed on 
the machine, you can use the WAN Adapters Setup Utility to 
change the board’s digital modem port properties. These 
properties identify the speech coding law to use with modems 
in your geographic location.

To set up digital modem port properties:

1. Select the digital modem port (x Digital Modems 

where x is the number of modems on the board) in the 

Facility Data Link protocols are used to exchange 
messages between the board and the remote end of the 
network. These messages are issued by the Telco to put 
the board in loopback mode for testing when problems 
occur. They are also used to transmit statistics about 
physical transmission errors on the line.
Two protocols are available for the facility data link: 
ANSI-T1-403 and ATT-54016. They are compatible 
with each other. 
Use the protocol(s) indicated by your Telco. If this 
information is unavailable, select both protocols.
