ROTECTION WITCHING
The D3LX system may be configured for either protected or non-protected mode. For protected mode, two
modules are installed: working and protect. The working module carries the signal, while the protect module is in
standby. Each working module uses 1 group, physically occupying 2 slots. Each protected module occupies an
additional 2 slots; there are four slots required for each D3LX system.
In protected mode, the offline module is switched into service whenever the D3LX determines that a service fault
has occurred in the online module.
