Customer Port Multicast TV VLAN
A triple play service provisions three broadband services, over a single
broadband connection:
• High-speed Internet access
• Video
• Voice
The triple play service is provisioned for service provider subscribers, while
keeping Layer 2-isolation between them.
Each subscriber has a CPE MUX box. The MUX has multiple access ports that are
connected to the subscriber's devices (PC, telephone and so on), and one network
port that is connected to the access device.
The box forwards the packets from the network port to the subscriber's devices
based on the VLAN tag of the packet. Each VLAN is mapped to one of the MUX
access ports.
Packets from subscribers to the service provider network are forwarded as VLAN
tagged frames, in order to distinguish between the service types, which mean that
for each service type there is a unique VLAN ID in the CPE box.
