ORDERING INFORMATION
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
