TIME SYNCHRONIZATION IN BROADBAND NETWORKS

TIME SYNCHRONIZATION IN BROADBAND NETWORKS

WE SYNC THE WORLD

The DOCSIS® standard was created for high-speed data transmission via cable television networks. With the newest specification DOCSIS® 3.1, speeds of up to 10Gbit/s downstream as well as 1Gbit/s upstream can be reached.

To achieve this speed, DOCSIS® 3.1 requires, among other, an absolutely accurate time synchronization of the network components. To this end, a grandmaster with IEEE1588v2 (Precision Time Protocol) is used in connection with the ITU G.8275.1/2 telecom profile. The time synchronization server DTS4160.grandmaster by Mobatime fulfills all of those requirements.

  • PTPv2 as per ITU G.8275.2 unicast IPv6
  • SyncE (Synchronous Ethernet) as per ITU G.8262/Y1362
  • NTP (Net time protocol)

In case of a loss of the time source (GPS), the integrated oscillator ensures a continuous high time accuracy. The DTS4160.grandmaster is available with three different oscillators:

  • OCXO oven controlled oscillator
  • DOCXO double oven controlled oscillator
  • rubidium atomic clock

 

Safety: The time server DTS 4160.grandmaster is equipped with a redundant power supply and can be connected to a second DTS 4160 for completely redundant operation
