ATS45 V.22bis EQM Threshold Value
S Register 45 is used to define the EQM (Eye Quality Monitor) value the modem will tolerate
before initiating an equaliser retrain sequence. This S Register applies to V.22bis only.
By setting this register with a low value, the modem will demand a high quality connection.
Setting a high value will allow the modem to operate on degraded lines without invoking retrains.
A value of zero will disable automatic EQM retraining for V.22bis.

The value in this register should only be altered by people with previous EQM
experience. Changing the EQM value will affect the data throughput and
reliability of connections.
Default

Example

modem will retrain the connection.
