5.5.1.2.4 LBO Menu
The above menu is for configure the T1 reach parameter. The T1’s transmit pulse is increased
with the change of distance. The transmit pulse is the largest when the LBO setting is at 533 ~ 655
feet and the transmit pulse is the smallest when the LBO setting is at 0 ~ 133 feet. This parameter
is used to compensate for the loss that will occur when longer wires are used for T1
transmission. The conversion factor between feet and meters is that 1 meter is approximately 3.3
feet. Hence, 655 feet is approximately 200 meters. When this parameter is used incorrectly, the
T1 interface will be receiving no signals or too strong of a signal which will cause T1 interface
malfunction.
