Carrier Access AB II 3.2.6 Line Build Out (LBO):

3-4

3.2.6 Line Build Out (LBO):

CSU 0 db/DSX (0’-133’), CSU -7.5 dB, CSU -15 dB, CSU -22 dB, DSX (133’-266’), DXS

(266’-399’), DSX (399’ - 533’), DSX (533’-655’)

Selects the signal level to be transmitted from the Access Bank II to the T1 line(s). The

default is 0 dB/DSX (0’-133’), which is the normal signal level required by most public car-

riers. It is important to remember that this setting can only be changed in the Remote mode.

A T1 signal level too high for the engineered facility can result in Bipolar Violations (BPV).

Too low a level can result in signal loss (LOS). Verify in advance the proper signal level

required by your service provider.
