The Ericsson OMS 3200 family of Optical MultiService Core Switches is the platform of choice for building high capacity, highly resilient intelligent core transport networks.

Ericsson OMS 3200 Product Overview

The Ericsson OMS 3200 Optical MultiService Core Switch enables operators to build a single, consolidated, highly resilient and intelligent low OPEX core transport network. OMS 3200 is highly capable of efficiently delivering Ethernet, OTN and traditional services.

Designed around a high performance ASTN/ASON  control plane the OMS 3200 series delivers new, resilient network protection schemes and enables new client driven service revenue opportunities.

The platform’s advanced control-plane and wide range of native traffic interfaces make it an ideal solution for building highly resilient optical networks to support SDH, OTN and IP traffic.

Key features
  • ASTN/ASON Control Plane; Reduces operational overheads and enhances network resilience
  • Dual Technology OTN/SDH Switch Fabric;
  • Enables new revenue opportunities and additional future proofing of the network investment
  • Embedded Layer 2 Ethernet and MPLS switching options
  • Embedded DWDM and OTN support for cost optimized, carrier grade transport
  • In-service scalability to meet current and future traffic demands
  • Full range of Ethernet, SDH, SAN and OTN Interfaces


Next Generation Optical Core Networks

Today, many core networks consist of multiple core technologies. Typically each set of parallel infrastructure
is dedicated to delivering a single service type e.g. TDM, IP or ATM. The OMS 3200 provides an opportunity to significantly reduce core network costs by consolidating all traffic types onto a single, robust and flexible core network.

The combination of multi service support and ASTN/ASON control plane ensure that all services can be delivered rapidly and with the appropriate quality of service.

Key Features

ASTN/ASON Control Plane

The introduction of ASTN in the transport network opens up a number of potential applications. Distributed functions allow fast execution of bandwidth-saving restoration schemes. Due to the new flexibility in transport service provisioning, new services can be offered.

The built-in auto-discovery functions for equipment and associated links improve
many processes in the day-to-day operation of the network. ASTN offers CAPEX-saving advanced protection schemes, OPEX savings automation of operational tasks, new revenue opportunities by enabling differentiated and novel services, and proven interoperability featuring standardized interfaces.

Ericsson enables operators to easily introduce ASTN into either existing or new network builds whilst retaining full control over the amount of resources dedicated to automatic restoration and/or provisioning. For example, both ASTN and traditional SDH-based protection and provisioning can be mixed in the same network, this has been successfully demonstrated in large multi-vendor networks.

The Ericsson ASTN Product portfolio includes the ASTN Planner that can be used either as an offline planning/evaluation package or as an integrated element of the ServiceON management suite. The application includes a full suite of planning utilities plus comprehensive scenario modeling functions.

The OMS 3200 series scales from 80Gbps though to 960Gbps to ensure operators can accommodate current and future traffic demands.

OTN (G.709) Support
OTN enables the transport of complete SDH signals including the overhead. In addition non- SDH services can be mapped into OTN bearers offering an additional degree of future proofing. OTN makes it possible to build pseudo transparent ASTN switched core networks.

Hot-pluggable optics
Carrier-class, small-form pluggable (SFP/XFP) modules can be incrementally added to cards in response to increasing demand. Optical technology includes CWDM/DWDM colored optics.

Multi-Rate SDH Interfaces
Lower rate SDH services (STM-1/4/16) are all supported on flexible Multi Rate units allowing each port to be configured on an individual basis to match the exact service requirements.

Multi-Protocol Data Interfaces
Data services are supported on a flexible Multi Protocol Data Unit. Each port can be configured from the management system to support the following services.
  • Ethernet 100/1000M and 10G LAN PHY
  • Fiber Channel, Fi-Con ESCON
IP Services Blade
Flexible data services are supported on the optional IP Service blade which is capable of Ethernet Layer 2 and MPLS based switching and aggregation.

Embedded WDM
For metro/regional applications the OMS 3200 offers a choice of embedded CWDM interfaces or a low cost, self-contained 4 x STM-64 WDM system to facilitate high capacity interconnection without the cost or complexity of external xWDM equipment.

The OMS 3200 has a full range of network protection options including ASTN/ASON, MSP (1+1 and 1:N), SNCP, dual-ring interconnection and multiple 2-fibre and 4-fibre MS-SPRING at STM-16 and STM-64. All common equipment including Switch Matrix, Controller and Power supplies can be configured with 1+1 redundancy.

The OMS 3200 is managed by the widely deployed ServiceOn solution that provides end-to-end integrated  network management for data and SDH, network-wide performance monitoring and rapid fault identification. A Java Craft Terminal is available for additional, focused Element Management. ServiceON Optical provides a full range of northbound
interfaces to facilitate integration with higher level management systems.

System architecture
All OMS 3200 series products feature a 1+1 protected switch matrix and control plane. Duplicated internal fast Ethernet connections provide communications between the system controllers and each individual chassis slot. Traffic access is via universal traffic slots that can take any of the available optical interface units. Plug-in VC-12/3 switches and Layer 2 Ethernet switches are also accommodated in traffic slots.
