9500 family overview
MPR-e and MSS-1c User Manual 3DB19901EFAA Edition 01 67
The high-capacity (HC) MPT ODUs are available in the following models. The models
share the same characteristics except where indicated below:
• MPT-HC—supports QPSK, and 8, 16, 32, 64, 128,and 265 QAM
• MPT-HC-HQAM—supports the same QAM range as the MPT-HC, but adds support
for 512 QAM and 1024 QAM
• 9558HC—supports the same QAM range as the MPT-HC, but operates only at 5.8
GHz
MPT-HC V2/HC-HQAM/9558HC is microwave equipment capable of transporting the
Ethernet traffic over an RF radio channel.
MPT-HC/HC-HQAM is microprocessor-controlled equipment that interfaces the MSS
with the antenna.
The input interface is a standard Giga Ethernet interface (electrical or optical).
The Ethernet traffic is transmitted over the radio channel according to the configured QoS
and to the scheduler algorithms.
Transmitter circuits in the MPT-HC V2/HC-HQAM/9558HC consist of Ethernet input
interface, modulator, local oscillator, upconverter/mixer, power amplifier, and diplexer.
Receiver circuits consist of diplexer, low-noise amplifier, local oscillator, downconverter/
mixer, automatic gain control, demodulator and Ethernet output interface.
The microprocessor manages the frequency, transmit power alarming, and performance
monitoring.
The power supply is provided through PFoE (electrical Ethernet cable) or a dedicated
power supply cable.
MPT-HC V2 is XPIC-ready, and requires the installation of a dedicated module.
The MPT-HC-HQAM has an integrated, on-board XPIC function which can be enabled by
software upgrade using a dedicated XPIC RTU license. No additional hardware module is
required.
The MPT-HC V2/HC-HQAM/9558H is frequency dependent.
The MPT-HC-HQAM does not require a solar shield.
