The OMS840 is fully compatible with Marconi's NG-SDH and Optical Multiservice products, management systems and PacketSpan technology



Marconi's OMS840 allows you to address business customers with Ethernet services alongside traditional TDM services with rapid payback on investment. The product can be equipped with 4 x 2 Mbit/s ports (balanced or unbalanced) and 4 x Fast Ethernet, whilst having the flexibility to be an STM-1 or STM-4 ADM or terminal.

TDM interfaces 2 Mbit/s (E1 balanced and unbalanced) alongside STM-1 or 4 SFPs (Small Form Pluggable modules) for scalability and flexibility.

Wirespeed Ethernet interfaces 10Base-T and 100Base-Tx Ethernet interfaces ensure the widest application.

This provides the ability to support legacy types of services such as TDM leased lines and PBX connections alongside new service offerings such as Ethernet Private Line (EPL), and developing multipoint Ethernet services such as Ethernet Virtual Private Line (EVPL), Internet/IP Access and EVPLAN/VPN*. The OMS 840 provides a cost-effective way of providing these applications, and preserves the carrier's brand image.

The product is transparent to the operation of the LAN and to the end-users, making the most of the ubiquity of Ethernet as the customer port.

The OMS840 can also be managed across islands of networks (via leased bandwidth from the PTT) via the creative utilization of the SDH payload overhead.

Ethernet-to-SDH conversion This cost-effective solution avoids the need to deploy separate general-purpose routers or LAN switches on the customer's premises, or the need for customers to add costly telco interfaces.

The OMS840 provides Ethernet-to-SDH conversion at the transport layer (via GFP), transporting Ethernet frames transparently across the SDH network. It also provides Ethernet domain statistics.

GFP provides a major benefit in terms of the possibility of multi-vendor (and operator) interworking.

    The applications EVPL, Internet/IP Access and EVPLAN/VPN are in conjunction with the PacketSpan Layer 2 tributary card.
