The manufacturer shall state whether the system uses the provisions of 47CFR15.323(c)(10) and
47CFR15.323(c)(11) and, if so, which EUTs are the “initiating devices” and which devices use the
provisions of 47CFR15.323(c)(11), and the manufacturer shall provide, in the test report, the appropriate
diagrams and other material to explain the use of the provisions of 47CFR15.323(c)(11). This test will be
performed on each type of initiating device that uses the provisions of 47CFR15.323(c)(11). The EUT is
the initiating device. The companion device is the “responding device.” Each type of initiating device must
be tested with each type of responding device.
This test validates the ability of the EUT to distinguish between same-system and other-system interference
for purposes of satisfying the requirement of 47CFR15.323(c)(11).
The test procedure is as follows:
a) Adjust the path loss between the EUT and its companion device such that the received signal to
the EUT from the companion device is at least 30 dB above T
L
.
b) By using either frequency administration commands or out-of-operating-region interference
applied to the EUT, restrict the EUT and its companion device to operation at a single carrier f
1
for TDMA systems and on f
1
and f
2
and corresponding duplex carriers for FDMA systems. If
out-of-operating-region interference is used to confine the EUT to the intended carriers, use the
procedures of 7.2.3 to ensure that the residual interference power from the out-of-operating-
region interference generator(s) does not corrupt the test results. Verify that the EUT and its
companion device can establish a connection.
c) Apply interference at T
U
+ U
M
per carrier to the EUT on all transmit time/spectrum windows on
the enabled carrier(s). The interference must use the same physical layer parameters
(modulation, frame format, etc.) as the EUT transmissions, but with a system identifier different
from that used by the EUT and the companion device. Ensure that the interference level at the
companion device is at least 10 dB below T
L
. Apply no interference to the receive
time/spectrum windows on the enabled carriers.
d) Cause the EUT to attempt to establish a connection. If a connection is established, the test fails.
Test report
Test reports are the means of presenting the test results to the appropriate procuring or regulatory agency or
for archiving the data in the files of the testing organization. As such, test reports shall be clearly written, in
unambiguous language.
Test report contents
The conditions of test given in Clause 6, Clause 7, and Clause 8 shall be described in the test report in order
for the test results to be properly documented.
Applicable standards
In addition to this standard, any standards to which the EUT was tested shall be clearly stated in the test
report. Where referenced standards have more than one measurement procedure, or where the referenced
