bit errors after the 10-second time frame. Provisioning codes
and responses shown in Appendix A.
9.3.2
Remote Query of Provisioned Parameters via 16-Bit
Commands
The NIU also allows the test person to query the NIU and deter-
mine its provisioned options. To initiate a remote query session,
the NIU is first put into loopback. Once in loopback, the test per-
son sends the appropriate 16-bit query code to the NIU. All
query codes must be sent to the unit for minimum of five sec-
onds. In order to see a bit-error response from the unit, the
query code must be present for a minimum of 20 seconds. Query
codes and responses are shown in Appendix B.

Power
9.4.1
Local Power Input Lead Fusing
The NIU offers a flexible powering option which will allow the
unit to operate directly from T1 metallic spans, or from a locally-
provided 22 to 56Vdc source. The NIU is fused on its local power
input lead, pin 35, to prevent the failure of an individual NIU
from affecting other units on the same local power supply. This
fuse is not field replaceable since failure is an indication of an in-
ternal fault of the unit.
- NOTE -
The 3115-80 is equipped with an on-board 3V Lithium battery. If power
is removed from the circuit for whatever reason, the battery circuit is en-
abled to maintain the real-time clock circuit. If the battery ever needs re-
placement, the unit must be returned to Westell.
9.4.2
PCB Powering Option Switch
The unit contains an option to configure the unit for either span
or local powering. The option must be set at the time of installa-
tion. Figure 11 shows the location of this option. Select either
SPAN or LOCAL, as required by the application.

TESTING & TROUBLESHOOTING
10.1
Testing and Field Repairs
This equipment should not be field repaired. If the equipment
is suspected of being faulty, replace it with another unit, op-
tioned identically, and retest. If the replacement unit appears to
operate correctly, the original unit may be faulty and should be
returned to Westell for repair or replacement (Paragraph 12.2).
10.2
Troubleshooting
If trouble is encountered, verify all installer connections to the
assembly and check that the CO power fuse is not blown. Also
verify all module connections and option switch settings, and
verify the modules are making a positive connection with the
