IDSL 12-PORT ACCESS MUX MODULE
The first switch for each port (the odd-numbered switches) are not used. The
second switch for each port (the even-numbered switches) sets the default speed
setting for the unit upon initialization. If the second switch is in the OFF position,
the line will run at 128 kbps. If the second switch is in the ON position, the line will
run at 144 kbps.
The Module ships with all switches in the ON position. Each port will run at
144 kbps by default.
Speed settings made via the web management system override the
hardware settings.
