Shelf Alarm
The –48V alarm (–48ALM) located on JP15, pin 6,
provides a –48VDC signal when the PAU fuse is
tripped.
Power Connections
The BR1/10 Wall Mount Chassis provides a three-
position terminal strip, JP16, on the backplane for
power connections . Ring lug terminations are
recommended for connecting to JP16. When using
the ADTRAN Wall Mount Power Supply, part
number 1150101L1, insert the –48V wire (BLACK)
into terminal 3 (–48I) of JP16. Insert the return wire
(RED) into terminal 2 (–48R). Insert the frame
ground wire (GREEN) into terminal 1 (FG). See
Figure 10.
Since the frame ground and the –48V return
are isolated in the bank, these grounds
should be connected externally to a central
ground.
OPTIONS
RS-485 Connection
The RS-485 link connection is made on JP17, pins 1
through 3, located on the bottom of the backplane.
This connection is provided for future applications.
LOC CK
When BITS is not available, JP17, pins 4 and 5,
provide a phase-locked-loop local composite clock
output. While not intended to provide multiple
outputs, this output can be used to provide a clock
source for a single channel bank when an external
output is required. This option can be used in a
tandem configuration that does not have a centralized
composite clock source.
When necessary wiring and connections are
completed, replace the clear plastic cover on the
backplane. The common equipment and channel units
may then be configured and installed. Refer to the
appropriate ADTRAN Practices for information
specific to each plug-in card.
3. MAINTENANCE
The BR1/10 Chassis requires no routine maintenance
to operate properly. Test and maintenance for the
specific plug-ins should be conducted in accordance
with the recommendations and procedures prescribed
in associated Installation and Maintenance Practices.
ADTRAN does not recommend that repairs be
performed in the field. Repair services are obtained
by returning the defective unit to ADTRAN's
Customer Service.
4. SPECIFICATIONS
Refer to Table 3 for unit specifications. Table 4
contains part number references.

ADTRAN will replace or repair this product within ten
years from the date of shipment if it does not meet its
