Packet-Switched Networking Solution for Teleprotection with Hybrid+ Transport Capabilities
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 coupled with a SONET/SDH-transport layer to produce a converged communications platform to reliably transport 64 kbps, T1/E1 TDM and Ethernet services 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.
Native TDM and TDM over Packet: xTDM offers the best of both worlds
Introducing the xTDM Access Card for the JunglePAX Hybrid Packet & TDM platform that offers the best of both worlds. This add-on unit offers the flexibility to support both native TDM over Hybrid WAN ports as well as emulated T1/E1 signals over MPLS, making it extremely flexible for all customer applications.
The xTDM Access Card key features:
JunglePAX Hybrid+ technology offers the best of both worlds by preserving SONET/SDH performance in a packet-switched network. This is achieved by adding an independent SONET/SDH layer alongside the MPLS-TP layer (without impacting its capacity) over the same optical WAN link. Use of this layer is optional and is intended for TDM-based relaying applications (C37.94, RS-232 Mirrored Bit, G.703 64k etc.) that are extremely delay sensitive.
Evolution Module - Optically connecting JMUX and JPAX for simplified interoperability
GE’s new Evolution Module (B86900-01) enables migration to MPLS ring-by-ring or node-by-node AND offering an upgrade opportunity to modernize hardware while preserving highly dependable SONET/SDH delay performance for critical services through deployment of JunglePAX Hybrid Mode. Evolution and Hybrid work together to ensure ongoing security and dependability across both SONET/SDH and MPLS planes.
4-port G.703 iDS0 unit
A new G.703 Access Card (90366-01) for JunglePAX is the latest iDS0 (internal DS0) card that joins 7 other access modules already available for this platform. In contrast to GE’s Direct Relay (DR) module (90350-01) offering a single RS-232 / G.703 (64kb/s) data port, this new iDS0 level module is equipped with four G.703 64kbps data ports thus providing efficiency and a lower per-port cost than its DR equivalent.
2-port Direct Transfer Trip iDS0 unit
This third-generation Direct Transfer Trip module provides two full-duplex channels, keyed at 48VDC, 130VDC or 250VDC (p/n 90441-01, -03, -05). Each channel can be routed over either SONET/SDH or MPLS transport layers. Compatible with GE’s DTT Test Panel and interoperable with DTT cards installed in Lentronics Multiplexers (JMUX/TN1U/TN1Ue and T1MX/E1MX/E1MXe/TTMX) products.
Advanced Network Management System for JPAX and JMUX NMS
GE’s Advanced Network Management System software enables service building over JunglePAX MPLS and SONET-layers. Due to the expanded set of service options now supported within JPAX firmware 1.18, a hierarchical list has been implemented within the NMS traffic manager to significantly simplify user interactions. Building a protected or unprotected service from one network edge to the other is supported over Hybrid WAN ports with version 8.3.
WAN Encryption for improved confidentiality
Encryption of all MPLS traffic carried over the WAN is now supported. This is a licensed feature, allowing users to encrypt individual fiber optic segments on any of the 12 WAN JunglePAX ports. After enabling Encryption on both sides of a WAN link, public/private keys will automatically roll based on the administrator’s configuration (30 min to 200 hrs), or keys can be manually renewed on each segment via the Web User Interface.

Purpose-Built for Teleprotection and Superior Performance
Single Solution Converging and Simplifying Operations
Ruggedized with modular design lowering total cost of ownership
The JunglePAX platform is designed for utilities with critical utility communications in mind. GE’s JPAX offers a truly converged solution with security and dependability for all applications whether they are critical Teleprotection circuits or for less time-sensitive business IT needs. Security and Dependability ensure data will be delivered and received on time when an actual data packet is sent, and data will not be falsely received when no data was sent. Both are key performance requirements to ensure utility communications reliably operate at all times. JunglePAX equipment is
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 designed for teleprotection applications with layers of redundancy to ensure there is no single point of weakness, industry leading protection switching within 3ms, and low end-to-end service latency within 1ms 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 ideal for power utility operations and IT applications, supporting the following typical applications:
Critical Operational Traffic (OT)
Essential Operational Traffic (EOT)
Critical Information Traffic (CIT)
Essential Information Traffic (EIT)
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
The JunglePAX comprises of replaceable and hot swappable interface cards which ensure that the platform is easy to maintain. The flexible mix of client service cards provides utilities with a solution that addresses changing communications requirements.

IT and OT applications have traditionally operated independently over disparate networks, each serving the utility networking groups differently. IT and OT-centric applications can remain separated (i.e., metering from protection) although converged application can share the same space, generating opportunities for utilities to improve OPEX and CAPEX through elimination of redundancy and simplification initiatives.
More components within utility systems are becoming intelligent and requiring new communication connections and functions, generating demand for:
GE and Ribbon Communications have partnered producing an optimized proposition for utilities requiring more from their network. This solution will protect people and critical assets, scaling across the entire communications landscape with information assurance as traffic flows securely across network boundaries.
