Connecting a CTS-500 System

The CTS-500 is a personal TelePresence system intended to support single-user TelePresence conferencing. The CTS-500 system includes a 37-inch display with an integrated codec, camera, microphone, and speaker. Additionally, the CTS-500 has a connection for an optional Cisco Digital Media Player (DMP), which you can use to display live or streaming video content when you do not use the CTS-500 for TelePresence meetings. The minimum room dimensions to support a CTS-500 are 8 x 6 x 8 feet.

Specifically, the CTS-500 includes the following:

• One Cisco TelePresence codec (a primary codec)
• One Cisco Unified 7975G IP Phone
• One 37-inch LCD display
• One high-definition camera
• One microphone
• One speaker
• One input for auxiliary audio
• One input for auxiliary video that you can use for a document camera or PC

The Cisco TelePresence primary codec is the center of the CTS systems. Essentially, all internal TelePresence components connect to it, and it, in turn, provides the sole access point to the network infrastructure.

Explicitly, the Cisco Unified 7975G IP Phone connects to the TelePresence primary codec through an RJ-45 cable that provides it with network connectivity and 802.3af Power-over-Ethernet (PoE).

Another RJ-45 cable connects from the TelePresence primary codec to the camera, providing the camera with 802.3af PoE. A second cable from the primary codec to the camera provides video connectivity.

A High Definition Multimedia Interface (HDMI) video cable also connects the primary codec to the 37-inch LCD display. This cable has a proprietary element for carrying management information instead of audio signals because the audio signals are processed independently by the master codec.

Additionally, a speaker cable and a microphone cable connect the speaker and microphone to the primary codec, respectively.

The primary codec also has inputs for auxiliary audio and auxiliary video. Auxiliary video can come from a PC connection or from a document camera connection. An IP power switch (IPS) provides control for the on/off function of the document camera, attached projector, and lighting shroud of the CTS unit through an Ethernet connection.

Finally, an RJ-45 cable provides 10/100/1000 Ethernet connectivity from the primary codec to the network infrastructure. Figure 1 illustrates these interconnections for a CTS-500 system.
