MetroAccess is an E-Access service type that enables Service Operators to reach their Off Net customer on the Metrofibre Access network and deliver Ethernet Private Line (EPL) or Ethernet Virtual Private Line (EVPL) services end to end on an Operator Virtual Connection (OVC). The Service Operator interconnects to the Metrofibre Access network via an External Network Node Interface (ENNI) at the peering point extending their network to the User Network Interface (UNI) NID installed at the customer’s location.

The E-Access service type has been deliberately simplified to enable ease of integration between the Service Operator and the Network Providers Carrier Ethernet Network.

The UNI to ENNI ingresses the Service Providers customer service frame with an addition of an S-VLAN tag at the UNI and is delivered unchanged to the ENNI.

The ENNI to UNI ingresses the Service Provider customer service frame at the ENNI and is delivered unchanged to the UNI except for the removal of the S-VLAN tag.
