11.6.20.5 LIU - Configuration Samples
The Line Interface Unit (LIU) is available in two different sizes and different output / connector options. All
outputs of a module can be operate in either the E1 or T1 in mode. Signal output settings can be done during
operation via the web interface. The selected mode is indicated by the LEDs in the retainer plate.
