DTE-3114 - Networked Quad QAM Modulator

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

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 (included)

 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

 DTE-3114 Applications

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