Polycom RealPresence 1800 Administration Manual page 426

● Group system 300/500 - behaves as the CTS 1000 and uses only one screen.
The Polycom MLA Server manages the conference template layouts for Telepresence systems.
The number of screens used by each TIP-enabled endpoint is determined during the capabilities exchange
phase of the dial-in connection. It affects the usage and allocation of resources used with TIP-enabled
endpoints.
Resource Allocation
The MCU media processor (ART) supports up to three TIP-enabled screens as follows:
● One TIP-enabled endpoint with three screens
● Up to three TIP-enabled endpoint with one screen
TIP-enabled endpoint with three screens must be handled by the same media processor. This endpoint may
fail to connect if there is no one fully free media (ART) processor available.
The MCU will always try to fill up one media processor with up to three TIP-enabled endpoint with one
screen, to save free media processors for TIP-enabled endpoint with three screens.
When monitoring an ongoing Telepresence conference with TIP-enabled endpoints (Cisco and Polycom),
virtual participants are used to indicate the additional screens in the in the Web Client. For example, if the
endpoint has three screens, the system will display three participants, one for each screen.
An additional virtual Audio Only participant is used for the audio only telephone connected to the TIP
endpoint.
Configuring Microsoft, Cisco and Polycom
Components
Carry out the following steps to configure the various system components to enable TIP.
To configure the Microsoft, Cisco and Polycom components:
1 Configure a SIP Trunk connection between the Polycom DMA system and the Cisco Unified
Communications Manager (CUCM).
For more information see the Polycom Unified Communications Deployment Guide for Cisco
Environments, Using a Polycom DMA System as SIP Peer.
2 Register the Collaboration Server to the Lync Server
a Install a Security Certificate on the Collaboration Server.
The Certificate is obtained from the System Administrator and saved on the Workstation.
b In the SIP Servers tab of the IP Network Services Properties dialog:
i Set Certificate Method to PEM/PFX.
ii Click Send Certificate.
The Install File dialog is displayed.
iii Browse to the saved Certificate on the Workstation, and click Yes to install it.
