Abstract:
1. A method of providing a combination of access to two different network domains through an access data network, comprising the steps of: provisioning a logical communication circuit extending from a customer premises through the access data network to a communication access node coupled to a first network domain, wherein the provisioning comprises defining the logical communication circuit in terms of a layer-2 protocol; at an intermediate node along the logical communication circuit, examining communicated information in transmissions from the customer premises, for a protocol encapsulated within said layer-2 protocol, to distinguish transmission types; forwarding each detected transmission of a first transmission type from the intermediate node to the communication access node over the logical communication circuit defined in terms of the layer-2 protocol; and forwarding each detected transmission of a second type, different from the first transmission type, to a second network domain logically separate from the first network domain.
