General Room Requirements and Recommendations

The following are required elements for a CTS 1100 room:

You must use an enclosed space.

You must have a room with the minimum dimensions that are specified in the "Minimum Room and Table Dimensions" section on page 2-2.

The room must meet minimum heating, ventilation and air conditioning (HVAC) requirements that are provided in the "Power Requirements" section on page 2-5.

The room must be supplied with electrical power as specified in the "Power Requirements" section on page 2-5.

The power and Ethernet outlets must not be positioned directly behind the CTS 1100 unit.

If you install two CTS 1100 systems in rooms that share a wall, you must not mount the systems on the same wall; mount the two CTS 1100 systems on separate walls.

The walls in the room must meet the structural guidelines as specified in the "Important Warnings and Cautions" section on page 3-1 in Chapter 3, "Assembling and Mounting a Cisco TelePresence System 1100."

The following recommendations or guidelines ensures that you have the best possible conferencing experience:

A white room is acceptable but not recommended for the best experience. Neutral colors work best for the floors and walls.

You can use color, décor, and signage in the room to communicate your brand and corporate identity.

Cisco recommends that you do not use colors with high contrast.

For more color information, see the "Room Color Recommendations" section on page 2-3.

Normal office lighting is usually sufficient for a good conferencing experience. However, Cisco recommends that you perform the following actions for the best experience:

Use indirect florescent lighting and avoid any direct lighting.

If your room has windows, install shades to reduce glare, especially for any windows that are directly behind the participants.

For more information about lighting, see the "Lighting Recommendations" section on page 2-4.

The CTS 1100 was designed to well in an office with normal sound levels. Large rooms, or rooms with high ceilings, can cause echo and reverberation issues. For more information about acoustics, see the "Acoustic Recommendations" section on page 2-4.

Minimum Room and Table Dimensions

Use the following size guidelines when selecting a room for your CTS 1100:

The minimum room size is 8 feet x 8 feet x 14 feet (2.4 meters x 2.4 meters x 4.3 meters).This minimum dimension assumes that one edge of the table sits against the left or right wall of the room, relative to the CTS 1100.

Note The CTS 1100 is 80 1/4 inches (204 cm) wide. For more information about the system size, see Appendix A, "Cisco TelePresence System 1100 Shipping Pallet Size, Weight, and Description of Contents."

The minimum distance between the edge of the wall where you install the CTS 1100 and the table is 52 inches (132 cm); minimum distance between the edge of the CTS 1100 screen and the table is 44 inches (112 cm).

Conference participants should sit between 8 and 12 feet (2.4 and 3.7 meters) from the display. The ideal distance is 8 feet (2.4 meters).

This table is five feet (1.5 meters) in diameter.

Recommended Table Height and Minimum Table Width

For all table types, the table must be 28 to 32 inches (71 to 82cm) high, and at least five feet (1.5 meters) wide at its widest point. 30 inches (76 cm) is the optimal table height.

You should allow 30 inches (76 cm) of space for each conference participant. Cisco recommends a maximum of two participants for the CTS 1100.

For guidelines about placing the table in the room, see Figure 4-10 in Chapter 4, "First-Time Setup."

Recommended Table Finishes

Cisco recommends that the table in your CTS 1100 room have the following characteristics:

The table tops should have a low-gloss finish (non-reflective surface)

If you use wood a table, the wood should be a neutral, light color

If you use a laminate or plastic table, the table top should be a neutral, light color (for example, off-white or light gray)

Cisco does not recommend using the following types of table tops:

A table that uses a very dark or heavily saturated color (for example, wood that is reddish in color, or uses a dark wood stain)

A table with a glass top

Any table top that has a reflective surface

Figure 2-1 shows examples of unacceptable table colors.

Room Color Recommendations

For information about room color recommendations, refer to the Cisco TelePresence Wall Color Reference Guide available at the following URL:

Lighting Recommendations

The cameras that are used in the CTS 1100 are designed to work well using normal office lighting. However, Cisco recommends that you use well dispersed, ambient light throughout the room.

The ideal lighting environment is to use indirect fluorescent lighting that uses bulbs with a rating of 4,100 Kelvins (4100k). You can supply the lighting either through recessed fixtures or pendant fixtures. Pendant lighting is best if your room is more than 9 feet (2.7 meters) high. Cisco does not recommend direct lighting.

For best results, one set of lighting should be in front of conference participants, and one set should be behind the participants.

The lighting in the room should be well controlled. You should block natural sunlight or other light that could enter through glass or thin blinds.

Cisco strongly recommends that your fluorescent lighting use electronic ballasts.

It is important to consider the direction of the lighting in your room. For conferencing purposes, lighting can come from three directions:

Key Light—This is the primary source of lighting and typically the strongest source of lighting. Key light is built-in to the CTS 1100 light reflector.

Fill light—This light is created primarily from the overhead lights in the room, and secondarily from the CTS 1100 light reflector. Fill light can reduce or eliminate shadowing on the conference participants that is created by the key light.

Back light—This optional light is projected behind the conference participants. Back light is generally indirect and creates separation between the participants and the room background.

If measuring light in the room, the light range should be between 250 and 800 lux.

For specific lux measurement specifications, see Table 2-1.

Table 2-1 Lighting Measurement Recommendations

Target Measurement in Lux (= lm/m2)

Overall illumination

300-400 lux

50 lux

All lighting should be evenly dispersed. There should not be areas of 250 and 450 lux in the same room.

Measured vertically with the light sensor pointed at wall or intended camera location (not pointed at the ceiling).

Shoulder light/Direct down light

600-700 lux

Generally, shoulder lighting should not be more the 400 lux greater than the overall illumination of the room, and should never exceed 800 lux

Measured horizontally at table height, with the light sensor pointed at the ceiling

Acoustic Recommendations

The CTS 1100 microphones and speakers are designed to be used in rooms that have typical office noise levels.

Rooms with excessive noise (greater than 55 decibels (dBA) might not provide the best conference experience.

Large rooms, high ceilings, or rooms that have a large amount of glass may experience reverberation. If possible, reduce reverberation to a level that is below 700 milliseconds across the voice spectrum (between 300 and 3000 Hertz).

Power Requirements

The Cisco TelePresence System 1100 requires one 20amp circuit @100V 120V (US electrical code requires maximum 16amp on a 20amp circuit) or one 10amp circuit @ 240V. Two receptacles must be provided for these circuits. The receptacles should be located on the wall near the intended location of the endpoint but not directly behind the endpoint.

Note Peripherals such as document cameras or alternate displays will require additional circuits and receptacles. Placement will depend on the type and location of the peripheral device.

HVAC Considerations

Planning the cooling for a CTS 1100 TelePresence room is important to insure the room remains comfortable for participants and the equipment is kept safe. As outlined in the overview section of this document, HVAC considerations should be given from the initial phase of choosing a room. The detail in the table below outlines the specific BTU output of a CTS 1100 when deployed as recommend and under typical operating conditions. Typical assumes normal usage conditions such that the system is not subject to 100 percent utilization rates and deployment following Cisco recommendations. i.e. room located on interior, proper air circulation, walls painted with neutral colors, temperature expected 72-76 degrees F. Within these guidelines and typical usage, diversity of 25 percent can be equated which lowers cooling requirements and increases overall efficiency. HVAC considerations should be given from the initial phase of choosing a room. Installing new cooling (or heating) systems can be time-consuming.

Note Conditions not consistent with these recommendations or typical usage may require additional cooling. Consult with an HVAC engineer to define building envelope and unique requirements. Additional equipment such as data displays, document cameras, etc. will require additional cooling.

Auto Collaboration Data Display

The Cisco TelePresence CTS 1100 ships with one unique output port that supports only one display of data shared from other CTS endpoints. This port supports standard HDMI connectors and cables. If you wish to connect more than one display for sharing data or presentations, it is necessary to purchase an HDMI splitter and connect it to the Auxiliary control unit port.

Note The high frame rate codec does not support 30 frames/sec in presentation-in-picture (PIP) mode. An external display is recommended.

The supported output resolution is 1024x768 at 50/60 Hertz and is supported by all Cisco LCD displays. Third-party displays which support these specifications may not be compatible. The HDMI to DVI cable for the data display has to be purchased by the customer.
