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-
ING message is displayed on the LCD once a test has
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.
The initiating U-BR1TE transmits the 2047 pattern for the
duration of the test. The user can view the pattern results
by choosing menu item 7)PATT RESULTS, and can inject
errors into the transmitted pattern by choosing menu
item 6)INJECT ERROR. Select NO LOOPBACK under
the B1 REMOTE LPBK menu to exit the test.
The B2 REMOTE LPBK operates exactly like the B1 RE-
, but the B2 channel is looped back rath-
