1. Product Description
1.1. Overview
The radio system serves as the Indoor Unit of a point-to-point microwave radio system
designed for microwave band operation with Outdoor Units (ODUs). Key features and
functions are as follows:
•
Line interface and conditioning functions necessary for transport of none, four or
sixteen PDH T1/E1 channels
•
Ethernet transport via two front panel 100BaseT RJ-45 user ports. The IDU can be
configured for standalone Ethernet transport, or a combination of T1/E1 and
Ethernet transport with aggregate transport rates of up to 170 Mbps.
•
Digital modem functions with configurable modulation modes of QPSK, 16QAM,
32QAM, 64QAM, 128QAM and 256QAM
•
Configurable forward error correction with settable interleaver depth (latency)

Front panel management interfaces include two dedicated Management Ethernet
ports and an RS-232 serial console port.
•
On-board Ethernet Switch together with dual dedicated management Ethernet
ports supports daisy-chaining of Ethernet Management
•
Supported remote management software protocols include a web (HTTP) GUI
interface, telnet and SNMP
•
Overhead admin serial channel interface (transported as side-channel over the
link)
•
Two FormC general purpose relays

-21 to -60V DC Power interface (positive voltage capability is optional)
•
All Outdoor Unit (ODU) interface signals are multiplexed onto front-panel N type
connector interface
•
Front panel LEDs indicate Power-on, Alarm and Fault status
•
Optional protected mode operation provides two ODU interfaces, with automatic
switching to hot standby ODU in the case of detected primary ODU failure.
Functional block diagrams of these are provided as Figure 1 and Figure 2.
Depictions of front panel interfaces are given as Figure 3 and Figure 4
