Higher Capacities
With an Nx2 Mbps backplane one INU/INUe with one DAC ES or DAC GE
supports Ethernet capacities to 200 Mbps; 200 Mbps represents the backplane
maximum and the maximum that can be transported over one radio link. For
Nx1.5 Mbps, 200 Mbps (128x1.544 Mbps) is the backplane maximum, but 150
Mbps is the maximum that can be transported over one radio link.
With an Nx150 Mbps backplane one INU/INUe with one DAC GE supports
Ethernet capacities to 300 Mbps, which represents the backplane maximum for
Nx150 Mbps, and the maximum that can be transported over one radio link.
Where higher Ethernet capacities are required two or more INUs are co-located
to provide parallel-path links.
The Ethernet data from each link can be held separate or link-aggregated to
provide a single high speed user interface. Such link aggregation is enabled
within the DAC GE, or on an external L2 switch. For information on DAC GE
link aggregation, refer to DAC GE on page 3-53.
Figure 3-8 summarizes the radio channel (link) options for an Nx150 Mbps
selection for Ethernet capacities from 150 to 600 Mbps. Up to 300 Mbps a single
INU is used, for higher capacities two co-located INUs are used.
