The iDirect Solution (example)
By simply adding a separate line
C or Ku-Band Satellite
card, the iDirect solution can
support different topologies
from the same chassis
It can also support multiple
satellite links
SCPC

The new iDirect Hub Chassis Line Card supports
network speeds of 18 Mbps Downstream, and 4.2
Mbps Upstream.
A single 20 slot Hub Chassis supports aggregate
speeds of 360 Mbps.

Adaptive Channel allows a remote to operate in a carrier at a different modulation
and FEC based on weather conditions at that site
Modulation and FEC can be changed on a burst-by-burst basis
Much higher availability of service
