ETL600 R4 - Power line carrier system

• Cost efficient communication solution for the reliable control and protection of the power grid
• Cost savings through common hardware- and spare parts inventory for analog and digital PLC systems
• Flexible architecture for easy integration into traditional and modern environments
• Reliable transmission of protection signals
• Efficient exploitation of sparse frequency resources through flexible bandwidth selection
• Backup solution for selected mission critical services normally conveyed over broadband media 

• Increased output power: 50 Watts and 100 Watts up to 1 MHz
• More compact architecture: new single rack 50 Watts version (6 height units)
• Enhanced network (LAN) functionality: 4 integrated LAN ports (3x electrical, 1x optical), supporting VLAN and latest Cybersecurity measures
• Single or redundant power supply for all rack configurations
• Digital transit of compressed voice channels: reduced delay and unchanged speech quality in tandem operations (up to 4 directions in a substation)

• Common architecture for digital and analog operation in the same platform
• Wide range of transmission bandwidth settings, programmable without exchanging hardware
• SSB and Multi-Carrier (OFDM) digital modulation with Trellis Coding
• Extended carrier frequency range up to 1000 kHz
• Single step modulation with Direct Digital frequency Synthesis (DDS)
• Up to 3 analog (APLC) channels, configurable for multi-purpose "speech plus" applications
• Digital high-speed channel (DPLC), configurable with respect to transmission speed and spectral bandwidth
• Up to 2 internal teleprotection systems with 4 independent commands each, adaptive signal processing ensuring shortest possible transmission times
• Special operating mode for single purpose teleprotection in 2 kHz transmission bandwidth
• Up to 4 integrated programmable low delay narrowband modems for up to 9600 bps, with adaptive equalizer for optimum performance
• Integrated programmable broadband modem for up to 256 kbps with automatic suppression of narrowband interferers
• Dynamic Speed Adaptation (DSA) for maximum data throughput and availability under difficult line conditions
• Up to 16 digital compressed voice channels for telephony services
• Integrated adaptive TDM-multiplexer for 10 data channels and 16 compressed voice channels
• Interfaces for serial data, Ethernet/IP traffic (integrated switch/router) and equipment configuration
• Graphical user interface (GUI) for convenient configuration, operation and maintenance
• Element Management System (EMS) for supervising and managing of the entire PLC network via LAN, station bus and Embedded Operations Channel (EOC)
• SNMP alarm traps for serving a communication network management system
