prioritization is not used, a single pair of uplink/downlink connections is
created.
Forwarding Rules: A Forwarding Rule is assigned to each Service, defining
various features that define the handling of certain message types in the
wireless domain. These features, that define the wireless broadcast domain for
all Services that use the Forwarding Rule, include Unicast and Broadcast
relaying, QoS Profile for Multicasts and Unknown Address Forwarding Policy.
The available features depend on the Service Type.
Aggregation: Several Services in the Wireless Domain may be aggregated into a
single Virtual Private Link (VPL) in the backbone domain.
Priority Marking: Ethernet frames transmitted to the backbone may be marked
with a configurable priority (DSCP or IEEE 802.1p), enabling the upstream
network to handle the traffic accordingly.
Auto-configuration: The Ethernet Addresses of the Subscribers' PCs are
automatically learnt just as in a standard Bridge. For each Ethernet Address it
also learns the VLAN behind the SU it belongs to.
Currently, the following Service types are supported:
L2 (layer 2) Data Service
PPPoE Data Service
VoIP Service
4.11.1.2 Service Types
4.11.1.2.1 L2 Service
L2 (Layer 2) service transports Layer 2 (Ethernet) frames between the subscriber's
site and the Network Resource located behind the provider's backbone and/or
between the subscriber's sites.
L2 service is transparent to the layer 3 protocol: it can also be used for PPPoE
traffic, and it support DRAP-based VoIP services.
4.11.1.2.2 PPPoE Service
PPPoE (Point-to-Point Protocol over Ethernet) Access service provides connectivity
between a PPPoE enabled devices at the subscriber's site and a PPPoE aware
