9508D UCC Digital Powerline Carrier Multiplexing System

  • RFL® 9508
RFL 9508 DSP Powerline Carrier System

Product Description

The RFL® 9508D UCC Powerline Carrier System comprises two integrated subsystems that consist of a highly integrated fully digital PLC terminals that incorporates the latest Digital Signal Processing technology (DSP) along with a unique digital packetizing multiplexer that integrates voice, data, multiple T1 or E1 data ports, and IP traffic over the digital power line carrier link.

The RFL® 9508D UCC offers a choice of two power output levels, and a wide range of options that also include plug-in teleprotection modules to complete an integrated communication system design.

The system is capable of Drop and Insert operation at the T1/E1 level. These features make for a unique product that integrates power line carrier sub-networks into large corporate WANs.

The equipment is designed to operate in the harsh environment of electric utility substations and is based on the successful and proven RFL® IMUX 2000 T1/E1 multiplexer where thousands are in use around the world.

Key Features and Benefits

  • Integrate high quality voice and multiple channels of variable rate data traffic across a reliable narrow band power line carrier link.
  • Use as a digital link between a power line and any existing or new digital network of any protocol.
  • 50 or 100 Watt PEP output power.
  • Programmable from 20kHz – 500 kHz frequency range with no components to change in the field.
  • Use to extend a WAN to a remote location over the power line.
