Configuration
5-11
The upstream voice stream is first coded at the DSP, then
transformed into voice packets at the CPU, and finally transmitted to
the IP network through port 1 of the LAN Switch chip.
The upstream data stream is accessed through ports 2–3, and
then transmitted to the IP network through port 1, without being
processed at the CPU. Therefore, only voice packets can be
configured with VLAN tag and precedence.
