5.1.1 Connecting a VPM220

The endpoint can be used with a HUAWEI VPM220 microphone array (VPM220).
When installing a VPM220, do not point any microphone towards the speaker.
Status Indicators on the VPM220
VPM220 status indicators quickly provide working status information.

VPM220 Cascading
The VPM220 provides 360° sound pickup and an optimal pickup range of six meters. In a
large conference room (of about 40 to 50 square meters) with only one VPM220, audio far
from the VPM220 becomes problematic; cascaded VPM220s can help alleviate this problem.
Dynamically cascading, connecting, or disconnecting VPM220s will not interrupt a
conference.
The TE80 can be connected to two cascaded VPM220s.
