Setup T1 Parameter, LBO
LBO (Line build-out) setting is an inherent part of T1 network element transmission circuitry. Because cable lengths between
T1 device and NTU vary, LBO settings are designed to adjust the output power of the transmission signal to achieve equal
level point (ELP) at the NTU.
For short distance of T1 cable, this device must decreases outgoing signal strength.
There are five type T1 LBO for selection : 0 ~133ft , 133 ~ 266ft , 266 ~399 ft , 399 ft ~ 533ft , 533ft ~ 655ft
