JunglePAX WAN ports supports standard MPLS

Both JunglePAX 10G WAN ports (1 & 2) now optionally support standard MPLS mode in addition to Hybrid mode as a user configurable option. Additionally, two out of four 1G WAN ports (4 & 6) now operate in standard MPLS mode (not user-configurable).

Use of standard MPLS mode allows for interoperability with foreign MPLS equipment and Ethernet microwave radio devices. Note that foreign MPLS and Ethernet radio devices generally don’t support the IEEE 802.3ae standard, which is used by JunglePAX as a basis for hybrid mode implementation. The 1G WAN ports 3 and 5 continue to support Hybrid mode only. Use of Hybrid mode continues to be advantageous in standalone JPAX network applications as it allows native, non-packetized TDM services and MPLS services to coexist on the same fiber.

The WAN ports in standard MPLS mode allows for tunneling JunglePAX NMS information through foreign packet-based devices/networks to ensure that all JunglePAX nodes are visible regardless of whether they are optically connected to each other or via foreign packet-based devices/network.

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.

This release also allows for establishing packetized point-to-point Nx64k services between xTDM-8A cards T, or T1E1-4A/CBUS-4A ports at the far end. Point-to-point Nx64k services between local xTDM-8A card and JIF-Share/CMUX/CDAX card residing at remote JMUX/TN1U/TN1Ue nodes are also supported via Evolution units.


The xTDM Access Card key features:

  • Up to 8 x bulk T1E1 services or up to 4 x CBUS ports (via future 90308-02 card)
  • Two ports per each RJ-45 connector, requiring the use of splitter cables to gain access to the even numbered ports
  • Supports transport of bulk T1/E1 over MPLS or SONET/SDH
  • Supports transport of Nx64kbps services over MPLS
  • Future supports for 1+1 redundant hardware configuration if two cards are installed in adjacent slots

Hybrid+ Mode, for critical teleprotection where 1ms latency is too slow

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.

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 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.

* future release

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:

  • Real time control in energy delivery support for heterogeneous networks and integration of previously segmented and disparate networks
  • Lower utility operational costs through economy of scale, and convergence of operation and information technologies
  • A converged network is required, with:
    • Increased system capabilities,
    • Ability to ensure the performance of critical and time-sensitive applications,
    • Simplified and secure technology

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.
