1x4 EuroDOCSIS SpectraFlow Module
The 1x4 EuroDOCSIS SpectraFlow module offers four upstream RF ports and
a single downstream RF port. Each of the four upstream ports provide up to
a 10 Mbps connection to HFC cable and support both QPSK and 16 QAM
modulation schemes within a frequency range of 5 to 65 MHz.
The single downstream port provides up to a 40 Mbps connection to your
cable network and supports both 64 and 256 QAM modulation schemes
within a 91 MHz to 858 MHz frequency range. The downstream port is
compliant with ITU J83 Annex A FEC for 8 MHz channelization.
The module is connected to the network by installing a DOCSIS module
backplate on the selected slot, then cabling to the RF connectors attached to
the backplate. Cabling to the backplate and not to the module itself allows
you to remove and replace the module without re-cabling. It also allows you
to cable slots in advance. For information about installing a DOCSIS module
backplate, see “Backplates” on page 83.
These modules are SpectraFlow enabled. For information about SpectraFlow,
see “Application Module Features”on page 26.
These modules are hot-swappable; this means you can remove and replace
the modules with the system powered on and running.

of each numbered callout, see Table 1-2 on page 26.
