GENERAL DESCRIPTION

INTERTEK TESTING SERVICES
Test Report Number: HK08060834-1 Page 10 of 72
FCC ID: T7HCT8015
2.0 General Description
2.1 Product Description
The MBU 400 is a 1.9GHz DECT VoIP and PSTN Gateway. It operates at frequency
range of 1921.536MHz to 1928.448MHz with 5 channels (1921.536MHz, 1923.264MHz,
1924.992MHz, 1926.720MHz and 1928.448MHz). The Base Unit is powered by a
switching AC adaptor 100-240VAC to 12VDC 300mA.
The circuit wiring is consistent under the requirement of part 68.
The antennas used in base unit are integral, and the test sample is a prototype.
The Model: RTX8015 is the same as the Model: MBU 400 in hardware aspect. The
difference in model number serves as marketing strategy.
Connection between the base unit and the telephone network is accomplished through
the use of USOC RJ11C in the 2-wire loop calling central office line.
2.2 Technical Description
The circuit description and digital modulation techniques are saved as filename:

2.3 Related Submittal(s) Grants
This is an application for Certification of a PUB - Part 15 Unlicensed PCS Base Station.
The device is also subject to Part 68 Registration. The FCC ID of the associated
handset is T7H-CT8010 and is in process of being filed.
A Verification report has been prepared for the digital device portion.
2.4 Test Methodology
The radiated emission measurements for unintentional radiator (if any) and AC power
line-conducted emission measurements were performed according to the test procedures
specified in ANSI C63.4 (2003). The radiated emission measurements for intentional
radiator contained in UPCS device, conducted emission measurements, Listen Before
Transmit (LBT) tests, Time Frame and Frequency Stability tests were performed
according to the test procedures specified in ANSI C63.17 (2006). All radiated
measurements were performed in Open Area Test Sites. Preliminary scans were
performed in the Open Area Test Sites only to determine worst case modes. All radiated
tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise
in the "Justification Section" of this Application. All other measurements were made in
accordance with the procedures in 47 CFR Part 2.
2.5 Test Facility
The open area test site and conducted measurement facility used to collect the emission
data is located at Garment Centre, 576 Castle Peak Road, Kowloon, Hong Kong. This
test facility and site measurement data have been fully placed on file with the FCC.

SYSTEM TEST CONFIGURATION

INTERTEK TESTING SERVICES
Test Report Number: HK08060834-1 Page 13 of 72
FCC ID: T7HCT8015
3.0 System Test Configuration
3.1 Justification
For emissions testing, the equipment under test (EUT) was setup to transmit continuously
in burst mode with pseudo-random data to simplify the measurement methodology.
Care was taken to ensure proper power supply voltages during testing. During testing,
all cables (if any) were manipulated to produce worst-case emissions. The handset (if
any) was powered by a fully charged battery.
For the measurements, the EUT was attached to a plastic stand if necessary and placed
on the wooden turntable. If the base unit attached to peripherals, they were connected
and operational (as typical as possible).
The signal was maximized through rotation and placement in the three orthogonal axes.
The antenna height and polarization were varied during the search for maximum signal
level. The antenna height was varied from 1 to 4 meters. Detector function was in peak
mode. Radiated emissions were taken at three meters unless the signal level was too
low for measurement at that distance. If necessary, a pre-amplifier was used and/or the
test was conducted at a closer distance.
The spectrum analyzer resolution bandwidth was approximately 1% of the EUT emission
bandwidth, unless otherwise specified.
Radiated emission measurements were performed from the lowest radio frequency signal
generated in the device which is greater than 9 kHz to the tenth harmonic of the highest
fundamental frequency or to 40 GHz, whichever is lower.
As the base unit has 2 antennas, both have been checked. While conducting the test on
one of antennas, another one was being disable its transmission. The data in this report
represented the worst-case.

3.2 Conducted Emission Test Configuration
The setup and equipment setting were made in accordance with ANSI C63.17. The
antenna of EUT transmitter was replaced by a coaxial cable. The impendence matching
of connection, cable loss and external RF attenuator were taken into account. The EUT
was arranged to communicate via a fixed carrier frequency between its transmitter and a
companion device. The transmission was configured in burst mode with pseudo-random
data as typical as normal operation.

3.4 EUT Exercising Software
The EUT exercise program (if any) used during radiated and conducted testing was
designed to exercise the various system components in a manner similar to a typical use.

Uncertainty and Compliance - Unless the standard specifically states that measured
values are to be extended by the measurement uncertainty in determining compliance, all
compliance determinations are based on the actual measured value.
3.7 Equipment Modification
Any modifications installed previous to testing by RTX Consumer Products Hong Kong
Ltd. will be incorporated in each production model sold/leased in the United States.
