Product Description

Introduction

The Vipersat CDD-56X Satellite Network Demodulator Router is ideal for
operators wishing to supply mesh connectivity between sites, while keeping
network infrastructure costs down. The CDD-564 and CDD-564L provide four
separate demodulators (the CDD-562L provides two) and an integrated router in
a compact, cost-effective 1RU package.
The CDD-56X simplifies Hub site installations by reducing rack space and cost
with 2/4 independent demodulators in a single chassis. A bank of CDD-56X
demodulators is ideal for a star network consisting of a single outbound carrier
at the Hub with multiple carriers returned from the remote sites.
The CDD-56X can be used at Hub sites where multiple burst controllers are
needed. Demodulator roles are defined via software, configurable either as a
burst controller in STDMA (Selective Time Division Multiple Access) mode, or
as dedicated SCPC (Single Channel per Carrier) inbounds from remote termi-
nals.
At Remote sites, the CDD-56X supports mesh connectivity between multiple
sites. Operating in mesh topology with links directly between sites eliminates
double-hops through the Hub, conserving bandwidth and reducing latency.
