Ethernet Services

Grid Telecom’s “state-of-the-art” DWDM network is constantly developing, covering the entire Greek territory, providing Layer-2 capacity services.
Grid Telecom's Ethernet services cover a wide portfolio of capacity services and allow its Customers to connect one or more of their points of presence in a flexible and cost-effective manner.

Ethernet services portfolio includes point-to-point (E-LINE), point-to-multipoint (E-TREE) and multipoint-to-multipoint (E-LAN) services. The Customer has a choice of circuit speeds ranging from 1 Gbps, 10 Gbps and 100 Gbps at competitive prices and with stable invoicing.

A physical port equipment at Customer's premises generates multiple Ethernet Virtual Connections (EVCs) with different points of presence. Each EVC has distinct characteristics, such as different speed or Quality-of-Service (QoS) than the other EVCs. Grid Telecom's Ethernet services are provided with extremely low latency and multiple protection paths ways, via its own DWDM network. Grid Telecom's backbone network high availability, combined with the physical protection options available at the Customer's points of presence, ensures uninterrupted provision of service.

Grid Telecom's DWDM nodes are interconnected via alternative routes achieving diversity and maximum availability of service by providing additional protection at the Customer's points of presence, such as dual entry into the Customer's premises or installation of dual active equipment. Service Level Agreement (SLA) is provided with guaranteed availability from 99.90% to 99.95%.

To enable the activation of the Ethernet service, Grid Telecom is installing at Customer’s premises “state-of-the-art” certified equipment with 100Base-TX, 100Base-FX, 100Base-LX10, 1000Base-T, 1000Base-SX, 1000Base-LX, 1000Base-SX, 1000Base-LX, 1000Base-ZX, 10GBASE-SR, 10GBASE-LR and 10GBASE-ER interfaces.

Grid Telecom's network is supervised on 24×7×365 basis by the Network Operations Center (NOC), staffed by experienced personnel, promptly responding to all Customer’s requests.


Grid Telecom's E-LINE service is a point-to-point Ethernet service that connects two locations via an Ethernet Virtual Connection (EVC).

E-LINE service concerns the connection of two points with symmetric capacity via Grid Telecom's proprietary DWDM network.

The Ethernet circuit is implemented according to the standards of the Metro Ethernet Forum via one EVC and the Customer's data is transmitted transparently, over the Grid Telecom network without any modifications.

Each Customer point is connected exclusively through optical access via Grid Telecom's optical fiber network.


Grid Telecom's E-TREE service is implemented by an Ethernet Hub & Spoke or Point-to- Multipoint topology, connecting multiple peripheral points to a central point location (Headquarters or Data Center).

Between the central and peripheral points, multiple Ethernet Virtual Connections EVCs are created, in the form of a "tree".

The E-TREE service is the most reliable option to interconnect the remote Customer locations to the Customer's central location through the nearest DWDM node of Grid Telecom’s network.


Grid Telecom's E-LAN service is a multipoint Ethernet service that simultaneously connects three or more locations through the required Ethernet Virtual Connections (EVCs, creating a single multipoint wide area network (WAN), extending the customer's local area network (LAN), so that data is securely and quickly transferred across the network.

The connection of each point is connected exclusively through optical access with the installation of equipment at each point of the same technology for immediate parameterization.

The comparative advantage of the E-LAN service is that any new point of presence can be directly interconnected with its central hub at low cost.
