Figure 5-1 Networking for separating voice packets with VLAN tag and
precedence
On the IAD108, only voice packets can be configured with VLAN
tag and precedence. This is due to the flow direction of packets in the
IAD. Figure 5-2 demonstrates the flow direction of packets in the
IAD108.
Ports 1–3 are the ports for external use. Port 1 is used for
upstream, ports 2–3 are used for accessing data user, port 6 is used
for interface use, and ports 4 and 5 are reserved.
The CPU achieves configuration of VLAN tag and precedence to
voice packets.
