DTE-3114 Features

  • Standalone four-channel QAM modulator with TS-over-IP (TSoIP) inputs and directly synthesized VHF/UHF outputs
  • Web and SNMP interface for setting parameters and observing status
  • Unit can be powered via the Ethernet cable (Power over Ethernet) or through a DC power supply jack

  • Supports IP de-encapsulation and 2D FEC decoding according to SMPTE 2022-1/2
  • Removal of IP jitter with programmable size of jitter-tolerance buffer
  • LCD status display shows device identifier, bitrate, IP/MAC address and status
  • Install up to 12 modules in 3U 19″ rack using the DekTec rack-mountable rail, or units can be mounted on a DIN rail directly on a wall

DTE-3114 Applications

  • Small-scale CATV networks
  • Cable-network simulator
  • QAM test-signal generator



Powering options

  • Through the Ethernet cable using:
    – IEEE 802.3af compatible PoE switch
    – PoE Midspan solution, e.g. 3COM 3CNJPSE
  • With DTE-PWR1 power adapter

For reliable deployment DekTec recommends to power the device using the Ethernet cable

DTE-3114 Limitations

  • Channels must be grouped: overall spectrum of the DTE-3114 cannot be wider than 32MHz
  • All channels must operate in the same mode and with the same symbol rate

Not supported:
– Scrambling of incoming Transport Streams
– SPTS-to-MPTS multiplexing
– VBR input streams
