Lentronics JunglePAX
Packet Switched Networking Solution for Teleprotection

GE's Lentronics™ JunglePAX is a purpose-built communications solution specifically designed for utility operations, providing the required security and dependability through layers of redundancy. The platform is based on MPLS-TP (Multi-protocol Label Switching with Transport Profile) technology that maintains deterministic performance through packet based communications providing utilities with increased efficiency and ease of integration.

The JunglePAX platform employs an optimized version of MPLS-TP, which offers a converged communications platform to reliably transport 64 Kbps, T1/E1 TDM and Ethernet service across an optical Wide-Area Network (WAN). With a flexible mix of WAN connectivity, access options, and with hardware redundancy on critical modules and control functions, the JunglePAX provide utilities a cost effective, single streamlined solution to better protect energy assets and improve system reliability.

Key Benefits
  • Improve service quality with a secure and dependable platform that provides reliable communications for utility applications within harsh industrial environments.
  • Maximize service uptime using purpose-built hardware to ensure utility-grade performance through built-in layers of redundancy.
  • Address emerging applications by implementing a flexible and scalable solution to assist with network convergence where traffic and application mix change.
  • Improve system-wide manageability with integrated and application-driven software that simplifies network management.
  • Increase control and promote information assurance with an advanced cyber-security platform that employs defense-in-depth strategies.

GE Advantage
JunglePAX Overview

GE’s Lentronics JunglePAX is a purpose-built fiber optic solution for high-performance industrial communication networks requiring mission-critical and time-sensitive communications within harsh utility environments. The platform provides private, secure, and reliable communication between collection/access sites, and guarantees performance over aggregation and backhaul networks for protection and/or control.

The JunglePAX has been designed for utilities with standards-based MPLS-TP for superior performance of packet delivery and network operations, taking into consideration the operational and environmental conditions and addressing the communication challenges that utilities are currently facing as well as meeting future business needs.

Teleprotection Application

Utilities are concerned about the impact on critical infrastructure and damage or injury associated with a fault condition on the transmission network. Teleprotection is a critical utility application that enables protection devices to communicate in a coordinated, reliable and expeditious way. Distance or directional comparison relays that send tripping signals require deterministic communications with low propagation delay edge (substation) to edge (substation), often as low as within 8ms. The faster the tripping signal can be transmitted across network, the quicker the dangerous energized state can be removed. Due to their importance, tripping signals cannot tolerate network disturbances affecting availability, capacity, physical communication failures, maintenance related outages or security vulnerabilities.

JunglePAX Solution for Teleprotection

The JunglePAX platform has been purpose-built for teleprotection applications with layers of redundancy to ensure there is no single point of weakness, industry leading protection switching within 8ms, and low end-to-end service latency within 4ms excluding propagation delay).

Below is a teleprotection application example, which walks through the sequence of events that the JunglePAX platform would perform to ensure that critical teleprotection circuits are delivered securely and dependably across the network.

Application Defined Networking

The Lentronics JunglePAX is purpose-built for power utility operations and IT applications, supporting the following typical applications:

Critical Operational Traffic (OT)
  • Protection and Control
  • Purpose-built for Teleprotection
Essential Operational Traffic (EOT)
  • Maintenance & Emergency Voice
  • Asset health and status
Critical Information Traffic (CIT)
  • Surveillance & Intrusion detection
  • Metering
Essential Information Traffic (EIT)
  • Business service backhaul
  • Connecting field offices and mobile users with operational data
Application Example: Transmission Cable Fault

Transmission cable fault
There is a transmission cable fault affecting the primary communication path

Fault detected
Fault is detected by the protection relay

Tripping signal
A tripping signal is sent to the JunglePAX platform

Fault detected and transmitted
The JunglePAX in Substation 1 detects the primary transmission path fault

Teleprotection signal received
The JunglePAX in Substation 2 detects the loss of the primary communications path and switches to the protected communications path within 3ms

Protection action
Protection relay initiates the action to clear the fault

Application Example
JunglePAX provides reliable inter-substation relay communications during primary communications path failures
