PVC Modes for Triple Play Implementation
MA5600T/MA5603T/MA5608T supports the triple play implemented in single-PVC multiple
services and multi-PVC multiple services modes.
PVC

Implementation Application Scenario
Single-
PVC for
single
service
Single-PVC for single service is a triple play
mode in which a PVC is adopted for carrying
one type of service.
This mode provides only the
Internet access service and is
used only in early days.
Multi-
PVC for
multiple
services
Multi-PVC for multiple services is a triple
play mode in which multiple PVCs are
adopted for carrying multiple services from
the MA5600T/MA5603T/MA5608T to each
DSL user terminal.
l On the user side, three PVCs are used for
carrying VoIP, IPTV, and Internet
services, and each xDSL port must be
configured with at least three PVCs.
l At the network end, three VLANs are
created for the upstream interface to carry
different types of services.
The home gateway
differentiates services based on
PVCs.
This mode is adopted to utilize
the previously-configured
services and previously-
deployed user terminals.
Single-
PVC for
multiple
services
Single-PVC for multiple services is a triple
play mode in which a single PVC is adopted
for carrying multiple services from the
MA5600T/MA5603T/MA5608T to each
DSL user terminal. The MA5600T/
MA5603T/MA5608T can differentiate
services by the following means:
l Ethernet type (IPoE/PPPoE)
l User-side VLAN ID
l User-side 802.1p value
l 802.1p value + VLAN ID carried in the
Ethernet packet
l Ethernet type (IPoE/PPPoE) + VLAN ID
The home gateway
differentiates services based on
Ethernet parameters such as
such as the VLAN ID or the
802.1p priority.
This mode is recommended if
the home gateway supports the
preceding function.
Service Priorities and Bandwidth
The different services have different request on the bandwidth and priority.
l Because the bandwidth and delay of the VoIP service are low, the priority of the VoIP
service is the highest among the triple play services.
