Configuration - Harris Stratex Eclipse 4.6 User Manual

Chapter 2. Eclipse Terminals
• The maximum capacity for each Licensed option may be used for Ethernet traffic, or
assigned between Ethernet and wayside E1 or DS1 circuits. For configurations where
available link capacity is fully assigned to Ethernet, capacity for Ethernet is reduced
by 2 Mbps (2.048 Mbps) for each E1 assigned, or by 1.5 Mbps (1.544 Mbps) for each
DS1, up to a maximum of 20x E1 or DS1 waysides.
Ethernet capacity (bandwidth) is assigned in 2 Mbps or 1.5 Mbps steps
to align with the capacity needed for E1 or DS1 waysides. Eclipse
incorporates a universal modem design that does not distinguish
between the type of data to be transported, Ethernet or TDM; data is
simply mapped into byte-wide frames to provide a particularly efficient
and flexible wireless transport mechanism, with the result that when
configured for Ethernet data, or Ethernet and TDM data, the full
configured capacity is available for user throughput. The data is
transported natively over the wireless link, whether Ethernet or PDH.
Ethernet physical (layer 1) link capacities/bandwidths used in this section
are nominal. For example, actual 100 Mbps link capacities are 106 Mbps
for an ETSI configuration, and 108 Mbps for ANSI.
Similarly, Ethernet throughput figures are nominal and are specified at
layer 2 in accordance with RFC 2544 recommendations.
