Ethernet Extension & Delivery Solutions

Metrodata offers a comprehensive range of solutions for Managed Ethernet Network Access and LAN Extension.

Connecting Ethernet over long distances normally requires Routers which require complex configuration.

However, Metrodata's Ethernet Extension products extend the functionality of Ethernet switches to join Ethernet LANs together, which means less equipment, fewer configurations and lower maintenance costs.

These Ethernet extension products enable you to interconnect your local area network (LAN)/ Ethernet over a wide area network (WAN) without the need for expensive and complex routers.

An example application would be to connect a remote office network to the headquarters over an external network

Ethernet over PDH

Ethernet over PDH (Plesiochronous Digital Hierarchy) is a way for transporting Ethernet traffic over PDH network links such as E1/T1 or E3/DS-3. It is one method available to Service Providers who are looking to add new Carrier Ethernet services over their existing legacy infrastructure.

For example, Ethernet over PDH can be used to leverage a Carrier’s PDH network to meet market demand for lower cost, higher bandwidth capacity, or by connecting leased E1/T1 or E3/DS-3 lines to their own packet switched network (PSN).

Metrodata's Ethernet over PDH edge devices support the key industry standards, including Ethernet Operation Administration and Maintenance (OAM) and encapsulation based on Generic Framing Procedure (GFP) to ensure better performance, carrier-class service compatibility and vendor equipment interoperability. In fact multiple leased lines can be bonded together for the delivery of higher speed Ethernet WAN services, using VCAT technology to bond these services together, as well as LCAS for resilience and automated recovery if a leased line fails, or is intermittent.

Ethernet over PDH Solutions

Metrodata's MetroCONNECT family offers Carriers and Service Providers easily implemented, effective solutions for extending Ethernet services over many different infrastructures, including legacy PDH transport networks. In addition to supporting Ethernet bandwidth delivery using GFP, Metrodata’s Ethernet over PDH solutions ensure consistent Quality of Service throughout the network as well as end-to-end performance, by enabling Carrier Ethernet OAM traffic management, thus facilitating a rapid, scalable and economical migration to Carrier Ethernet services.
