2.3.2.5 Dip switch configuration
The units feature four dip switches numbered from 1 to 4, which are accessible
on the rear panel, for access to cable equalization and the equipment software
configuration memories.
The ON position is down and the OFF position is up.
Cable equalization
Previous to connect the link cable from CU to CCU, dip switch number 2 must
be selected as shown below :
• If cable length is less than 150m., the dip switch number 2 must be set to ON
position (down).
• If cable length is greater than 150m., the dip switch number 2 must be set to
OFF position (up).
By this selection, the most proper equalization will be used to grant a low error
rate in the digital link circuits.
