1x4 EuroDOCSIS SpectraFlow Module with Spectrum
Management
The 1x4 EuroDOCSIS SpectraFlow module with Spectrum Management
offers four upstream RF ports and two downstream RF ports. Each of the 4
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 two downstream ports consist of an active port (F2), that is always
activated and contains the downstream carrier, and a failover port (F1), that
is only activated during failover. When configured for redundancy mode, the
maximum transmit output level is 57dBmV.
If the module is not configured for redundancy mode, then port F2 is
unused. Port F1 is then the transmit signal, which has a maximum output
level of 50-61dBmV.
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 and support Spectrum
Management. For information about SpectraFlow or Spectrum
Management, 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.

Management. For a description of each numbered callout, see Table 1-2 on
