Deployment Architecture 2 - MS AV MCU Cascade
Cascaded VMR Participants (Lync 2013 clients) connect to a conference on a Microsoft AV MCU which is
cascaded with a Collaboration Server.
In this deployment architecture, participants connecting to the conference by way of the Collaboration
Server are referred to as Cascaded VMR Participants.
Lync clients place calls to a Virtual Meeting Room provisioned on the DMA, for example,
1234@dma.example.com
The Cascaded VMR connects as a Lync client to the AV MCU.
The Collaboration Server utilizes the SVC Codec’s Temporal Scaling capability to send up to three
simulcast video streams to the AV MCU, each at multiple frame rates.
The Collaboration Server receives media from up to five different Lync clients from the AV MCU.
Lync clients experience a Microsoft Point to Point conference with Cascaded VMR Participants
appearing as Lync clients.
Cascaded VMR Participants experience a conference with Polycom video layouts.
Lync clients will see the active speaker from the
Cascaded VMR while Cascaded VMR Participants will see up to 5 Lync clients in addition to other
participants.
