FIELD: physics, computer engineering.
SUBSTANCE: invention relates to providing a remote customer service interface in a provider terminal bridge. The invention provides a method and a provider terminal bridge, designed to provide a virtual C-tagged user network interface (VUNI) service interface or a port-based interface. In one embodiment, the provider terminal bridge includes a customer VLAN (C-VLAN) component, a first service VLAN (S-VLAN) component connected to the C-VLAN component and to a metro Ethernet network (MEN), and a second S-VLAN component connected to the C-VLAN component, the first S-VLAN component and to an external network interface (E-NNI). The provider terminal bridge is configured to provide a service interface, a VUNI, or a port-based interface without using the S-VLAN mapping component.
EFFECT: supporting new functionalities without additional hardware.
