These configurations are made by using a MLU or a SOPHO-LAM P375.
You can make a choice between the MLU and SOPHO-LAM convertor configuration.
Generally you can make a choice based on the following characteristics:
• MLU convertor configuration
Advantages:
-
support of all synchronous speeds up to 64 kbit/s;
-
support of automatic convertor interconnection (only the destination DNR has to be
dialled);
Disadvantages:
-

-
Hayes modems are not supported because the modem has to operate in the CT108.1
mode.
