Installation Guide
LBO Switch (functional only on T3 cards)
Set the Line Build Out (LBO) switch up to support a long haul connec-
tion if the length of your coaxial cable is between 255 and 1200 feet.
Set LBO down to support a short haul connection if the length of your
coaxial cable is between 0 and 255 feet. The default setting is short
haul.
CLP Switch
The Copper Loopback (CLP) switch enables/disables loopback on the
copper port. When copper loopback is enabled, the incoming data and
clock are looped from the RX copper port to the TX copper port, thus
returning the copper input back to the sending device. At the same time,
the data is transmitted to the remote T3/E3 line card. However, data
from the remote card is ignored. Loopback is disabled by default. For
more information, refer to “Loopback Modes” in the User Guide
section of this manual.
FLP Switch
The Fiber Loopback (FLP) switch enables/disables loopback on the
fiber optic port. When fiber loopback is enabled, the incoming data and
clock are looped from the RX fiber port to the TX fiber port. The data
is also transmitted to the copper port, however, data from the copper
port is ignored. Loopback is disabled by default. For more information,
refer to “Loopback Modes” in the User Guide section of this manual.
