The industry’s first full DOCSIS 3.1 CCAP line-card, the DS8x192, is the
downstream module in the C100G. It supports DOCSIS 3.1, EuroDOCSIS
3.0, and DOCSIS 3.0 standards for service provider flexibility. The 8 physical
RF F-connector ports each support the entire 1.2GHz spectrum (48MHz
to 1.218GHz) for OFDM channels, and support SC-QAM. The narrowcast
channels on each port can be used to transmit DOCSIS packets, SDV stream,
and VOD stream on the same port. The DS8x192 also provides a pool
of shared channels, which can be used to support linear broadcast, or as
narrowcast channels by dividing the pool and assigning the channels to
each individual RF port.
