NOTE:
WSW50 is applicable to models equipped with an SDAA circuit.
Selectors 5 and 6: Current control to be applied immediately after connection of the line
FAX models equipped with an SDAA circuit (on which an NTU chip is mounted) might not be
connected to a broad band line such as an ADSL (Asynchronous Digital Subscriber Line) in a stable
condition. If those models fail to connect to such a line, try to change the current control to be
applied immediately after connection of the line by using selectors 5 and 6.
If selectors 5 and 6 are set to "0" and "1," respectively, the SDAA draws more current, decreasing
the period required to terminate the current control. If they are set to "1" and "0," the SDAA finely
controls precision of the termination current against the voltage to approach nearer to the specified
DC curve that specifies the current vs. voltage characteristics of the network termination. Selecting
either control may solve an unstable connection problem.
