Overview
To synchronize the C4/c CMTS to a network time server, you must choose Network Time Protocol (NTP) as your
synchronization protocol.
If preferred, you may operate the C4/c CMTS on the local (internal) clock of the C4/c CMTS without synchronizing it to a
network; however, if you intend to enable PacketCable, you must use NTP.
Local (Internal) Clock
When NTP and TOD are not used, all DCAMs and UCAMs are synchronized to the internal clock. This synchronization
includes frequency synchronization and DOCSIS time stamp synchronization.
