displays the position switch settings at
network locations.
Front Panel Features
The U-BR1TE V front panel features a two position
DIP switch, a recessed pushbutton, a rotary switch, a
bantam jack, and LEDs, as illustrated in Figure 1.
The B1/B2 DIP Switch selects the desired bearer
channel, B1 or B2, to be tested during local tests
using the U-BR1TE V front panel.
The NORM/PTRN DIP Switch is recessed to prevent
inadvertent operation. The ten-position rotary switch
is used to determine the specific test that will be
performed, including downstream loopbacks
(see
Table 2
).
LED indicators display current status of the unit, as
listed in
Table 3
.
