Harris Stratex Eclipse 4.6 User Manual page 49

Data throughput options range from 20 to 200 Mbps, and depending on the selected
throughput, channel bandwidth ranges from 7 to 56 MHz, with modulation options
from QPSK to 256 QAM.
Link capacity may be fully assigned to Ethernet traffic, or between Ethernet and up to
8 wayside E1/DS1 circuits.
Inter-frame gap (IFG) and preamble stripping and re-insertion is used across the link
to maximize Ethernet throughputs.
Capacity is licensed. The base configuration supports a 20 Mbps data throughput, with
higher capacities to 200 Mbps obtained by requesting additional capacity upgrades at
time of order, or as field-downloadable software licenses.
Protected 1+1 operation is not supported.

IDU ES is included in Harris Stratex Networks' Connect ES link package; a package
comprising two terminals, each with one IDU ES, and one ODU 300 outdoor unit,
which depending on the required throughput can be ODU 300sp, hp or ep.
Synchronous or asynchronous auxiliary data and alarm I/O options are included.
Requires ODU 300ep, ODU 300hp, or ODU 300sp.
IDU ES can be over-air interfaced to an Eclipse Node comprising the INU, DAC ES and
ODU 300. Where E1/DS1 side channels are required a DAC 4x or DAC 16x is included.
Similarly an AUX is included where auxiliary channel services are required.
IDU GE 20x
IDU GE 20x supports Gigabit Ethernet plus up to 20xE1 or 20xDS1 waysides.
Its Layer 2 switch supports two customer 10/100/1000base-T electrical ports, and an
optional SFP port for either 1000Base-X optical or 1000Base-T electrical. These
interface to one or two transport (link) channels using transparent, VLAN or mixed
operational modes.
Switch features include RWPR (Resilient Wireless Packet Ring), layer 2 link
aggregation, and comprehensive QoS options with VLAN tagging and jumbo frame
support.
Depending on the required Ethernet throughput, channel bandwidth ranges from 7 to
56 MHz for ETSI, and 5 to 80 MHz for ANSI, with modulation options from QPSK to
256 QAM. Maximum Ethernet throughput is 360 Mbps using one or both transport
channels.
Configured link capacity may be fully assigned to Ethernet, between Ethernet and up
to 20xE1 or 20xDS1 side circuits, or to E1 or DS1 circuits only for a maximum of 20xE1
or 16xDS1.
Inter-frame gap (IFG) and preamble stripping and re-insertion is used to maximize
data throughput.
