Deployment Architecture 2 - RealConnect Cascaded
Conferences
Cascaded VMR Participants (Lync 2013 clients) connect to a conference on a Microsoft AVMCU which is
cascaded with a Collaboration Server that is paired with a DMA.
With this deployment architecture, participants connecting to the conference by way of the Collaboration
Server are referred to as Cascaded VMR Participants.
●
Lync clients connect to the Lync 2013 AVMCU in either ad hoc or scheduled scenarios.
●
The Cascaded VMR connects as a Lync client to the AVMCU.
 The Collaboration Server utilizes the SVC Codec’s Temporal Scaling capability to send up to three
simulcast video streams of different resolutions, of the current speaker to the AVMCU.
●
The Collaboration Server receives media from up to five different Lync clients from the AVMCU.
●
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.
●
Lync 2013 clients, connected by means of the Lync AVMCU, in point to point calls, can connect to
Collaboration Server VMR participants by escalating the Lync call to a multipoint conference,
including the Collaboration Server VMR meeting room and its participants.
 The Contact List can be used to select participants followed by, right-clicking and selecting Start
a Video Call.
 An ad-hoc (Meet Now) Lync conference can be started; a drag-and-drop operation can then be
used in the Contact List to add a Cascaded VMR to the conference.
