CMTS Bridges for Explorer 8300 Set-Tops
To support DOCSIS-capable set-tops operating in DOCSIS mode, you must
configure CMTS bridges on the DNCS. A bridge is either a single QPSK modulator
or a collection of CMTS devices.
Any CMTS that joins a multicast group defined for a CMTS bridge becomes part of
Any CMTS that joins a multicast group defined for a CMTS bridge becomes part of
the hub associated with that bridge. In addition, all CMTSs joined to the multicast
group receive the same OOB data. For these reasons, it is important for operators to
ensure all CMTSs joined to the multicast group of a CMTS bridge do actually belong
on the hub for the bridge.
In SR 4.0, the new Set Up CMTS Bridge window allows you to configure CMTS
bridges. To configure the CMTS bridge for multicasting, you must enter a multicast
IP address in the range from 225.0.0.0 to 239.255.255.255. Detailed instructions for
creating CMTS bridges and completing the parameters in this new window are
included in the DNCS Online Help.
