Remote loopbacks of the B1 channel in the network-to-
customer direction are initiated by selecting items under
this menu. The loopback may be requested for this unit
and the five next U-BR1TES toward the NT1. A LOOP-

been initiated. The initiating U-BR1TE sends the loopback
command and begins transmitting the internally generat-
ed 2047 pattern. When the U-BR1TE begins receiving the
2047 pattern, it displays FAR END LOOPED on the LCD.
