Rules of connection settings
It is necessary to stick to the following rules while configuring the modems:
•
One modem should be set in the “MASTER” mode and the other should have this mode disabled.
Usually the “MASTER” mode is enabled on the provider or central office side because in this mode
the modem can affect the connection parameters.
•
The value of “ADAPTIVE” parameters should be equal on both modems.
•
For 4,6M connection, the value of “OPERATE” parameters must be set to “Transparent” on both
modems.
The time of connections in ADAPTIVE mode depends on the current line conditional and can be up to 5
minutes.
