Ericsson OMS 2400 Packet Optical Transport
  - Encore

The Ericsson OMS 2400 is a family of Packet Transport platforms, covering a range of switch and port capacities. It offers network operators and service providers a high level of carrier class Metro Ethernet functionality for evolving Broadband services.

Product Overview

The Ericsson OMS 2400 is a family of Packet Transport platforms, covering a range of switch and port capacities. It offers network operators and service providers a high level of carrier class Metro Ethernet functionality for evolving Broadband services.

OMS 2400 is positioned as a packet transport node based on Ethernet aggregation and switching for use in metropolitan networks, although its flexibility and scalability (including photonic integration) makes it also suited for core network applications. OMS 2400 enables the mixed delivery of native Ethernet client signals as well as legacy TDM traffic.

Key features and benefits for OMS 2400 include:
  • Ethernet transport switch capacities from 80Gbit/s to 320Gbit/s (full-duplex)
  • Full service Broadband” service support, including business Ethernet (E-LINE, E-LAN, ETREE) and multimedia services with IPTV based on IGMPv3 snooping and proxy reporting
  • Full Layer-2 Provider Bridge functionality for Ethernet traffic switching and transport
  • Packet Transport features, such as MPLS-TP and PB/PBB with OAM and Protection Switching


Optimized to deliver
The OMS 2400 is optimized to deliver Ethernet
Layer 2 VPN services (EPL, M-EPL, VPL,
EVPLAN) for end-to-end services or as an aggregation and grooming function for use with
edge routers and BRAS to deliver a wide range of broadband services.

Full Service broadband services

The OMS 2400 is specifically designed to transport IP-based Full Service Broadband
services such as VoIP, High Speed Internet, IPTV, VoD, L3 VPNs, and business IP
applications. Multicast services based on IGMPv3 snooping allows efficient distribution of
high-bandwidth streaming signals both in network paths and towards client equipment.

Resilience and security
MPLS-TP, with its associated OAM functionality, offers operators and service providers’ traffic management, sub 50ms network and equipment protection necessary to support a wide range of services and service levels. Security is handled through strict resource control (e.g. admission control) and strict functional plane separation to complement the overall carrier grade requirements.

Network Applications

OMS 2400 family is an ideal choice for aggregating customer services from the metro edge (e.g IP DSLAM traffic) or for aggregating and grooming traffic in the metro/core, in a
variety of hubbing, ring or meshing topologies.As well as offering native Ethernet interfaces up to 10Gbit/s, the OMS 2400 has a range of other optical options, including TDM Circuit Emulation, GFP mapping into SDH, CWDM and G.709 DWDM

The use of plug-in blades and SFP/XFP modules allows the OMS 2400 to be configured and reconfigured to reflect the changing demands as, for example, networks progressively migrate from client data (or CE/PWE3 services) mapped into SDH/SONET (GFP) to full Ethernet presentation. Similarly, on the network facing (aggregate) side, this flexibility enables the OMS 2400 to be used over existing SDH/SONET or Ethernet links, as required.

Support of legacy services

CES technology allows for transporting voice over packet by tunneling TDM traffic, through any type of cell-based or packet-switched network, including ATM and IP/Ethernet. Compared to VoIP, CES supports a much wider range of applications, allows service providers to maintain revenues from legacy TDM services, and lets enterprise clients maintain their existing network infrastructure investment.

Interoperability with existing TDM networks
Interfacing to existing TDM networks is achieved through the flexible mapping of Ethernet traffic into VCs (VCAT, GFP and LCAS). These technologies provide bandwidth efficient ability to flexibly allocate traffic to Ethernet over SDH links. As a result the OMS 2400 can operate as a hub aggregating packet traffic from other existing MSPPs or as a feeder node into large backbone OCS.

Tailored for today, flexible for tomorrow

The OMS 2400 can be software upgraded in service, while traffic cards may be added with no impact on existing operations. Moreover, with a flexible, low-first-in-cost the OMS 2400 provides a solution for today's needs with the flexibility to change and/or grow for tomorrow.

Key Advantages

OMS 2400 features a carrier class level of scalability to address the growth of operators’
packet transport network and services.

Scalability and high-density tributaries
OMS 2400 family features a choice of different chassis for effective and scalable solutions for different network scenarios. High-density tributaries, combined with hot-pluggable SFP/XFP modules help deliver maximum revenue generation at low incremental cost.

Reducing OPEX by simpler network operation
The OMS 2400’s efficient traffic management, advanced automation features, provisioning tools (ENEA and EPOC) coupled with its Control Plane and ServiceOn network management, makes possible the optimization and simplification of network operation, including I&C. Using end-toend integrated network management for both SDH / SONET and data paths, network-wide performance monitoring and rapid fault identification, simplifies day-to-day activities for troubleshooting, protection and provisioning.

Optimizing CAPEX in the network

The comprehensive Layer 2 features of the OMS 2400 offers an effective alternative to increasing the capacity of PE and core routers, by handling traffic which the routers do not need to deal with (for example, pass-through traffic and/or leased line business services). This optimizes CAPEX by reducing the need for expensive router resources, whilst the comprehensive protection and shared restoration capabilities of the OMS 2400 makes it possible to reduce network resources devoted to protection paths.

Performance with MPLS-TP and Ethernet

OAM functionality supported by MPLS-TP and Ethernet provide valuable performance visibility for the monitoring of data paths and for fast protection switching. This enables fast and efficient fault location and forwarding mechanisms for remote signaling of failures and defects. The support of MPLS-TP and PB/PBB provide a complete and coherent architecture for handling the operational realities of today’s packet networks.


Ericsson’s ServiceOn OSS solution manages the full Ericsson Broadband Network (Optical, Wireless and Broadband Access) product range, delivering end-to-end, best-in-class, service oriented management with seamless OSS integration.
