ADTRAN D4 U-BR1TE V Figure 6. Position Switch Settings at Network Locations for ISDN Applications

6 Section 61104020L4-5, Issue 3 61104020L4-5C
Figure 6 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.
