Cisco TelePresence vs. Videoconferencing

Does it really feel like you’re ―there‖ in the room?

Can it truly replace a face-to-face meeting?

Is each participant adequately seen and heard?

Is it utilized heavily, or does it just sit in the corner?

Cisco TelePresenceWhat It Is Today—The Cisco TelePresence Meeting

A true replacement for face-to-face meetings

As good as actually being there

Feel as if you’re actually in the same room together

Travel the world without ever leaving your office

As easy to use as an in-person meeting

Cisco TelePresence SystemNetwork Connectivity

Phone and Primary Codec both reside on the Voice VLAN

Primary Codec passes CDP and 802.1Q/p between the phone and network.

Switch sees two CDP Neighbors.

Switch QoS trust is extended through the codec to the phone

Example:

Console(config)#interface Gigabit 0/16 Console(config-if)#switchport mode access Console(config-if)#switchport access vlan 261

Console(config-if)#switchport voice vlan 262Console(config-if)#spanning-tree portfast

Provision 5.5Mbps per CTS-500/1000 15Mbps per CTS-300/3200 supported for 1080p

Bandwidth must be provisioned for the max. number of segments supported on the multipoint device

Any audio format CUVC supports

1. All CTS endpoints will send a copy of their audio in G.711 format

2. CTMS determines which CTS segment is emitting the most dominant audio and requests it to send a copy of that segments video in CIF resolution

3. CTMS mixes the G.711 channels from all CTS endpoints into a single G.711 channel and switches CIF and G.711 to CUVC

4. As the dominant audio segment changes throughout the meeting,CTMS switches the CIF video stream accordingly

Cisco TelePresenceCUCM Cluster Requirements and Recommendations

Cisco TelePresence requires CUCM version 6.0 or later

Cisco TelePresence has unique bandwidth and QoS requirements—but CUCM cannot differentiate between a TelePresence call and a regular Video Telephony call (to CUCM they’re both ―video calls‖)

All CTS systems must be registered to the same CUCM cluster because CTS-Manager can only integrate with a single CUCM cluster

Conditions:

Yes CUCM 6.0 or later?

No Video Telephony appsdeployed?

No More than one CUCM cluster?

Recommendation:

Use existing CUCM cluster

Requirements:

Conditions:

Yes CUCM 6.0 or later?

No Video Telephony apps deployed?

Yes More than one CUCM cluster?

Recommendation:

Pick one of your CUCM clusters and use it for all TelePresence systems globally

Conditions:

No CUCM 6.0 or later?

Yes Video Telephony apps deployed?

No More than one CUCM cluster?

Recommendation:

Deploy a separate CUCM cluster for TelePresence

Cisco TelePresence CUCM Dial Plan Considerations

Plan your dial plan wisely and select the appropriate Directory Numbers, Partitions and Calling Search Spaces used

Audio Add-In feature: access to the rest of your IP Phones, MeetingPlace, or the PSTN is required. Either deploy a voice gateway or trunk to your existing CUCM cluster

Future B2B connectivity will require CTS dial plan to be externally reachable

Consider 911 access

Recommend installing a second Cisco IP Phone on the wall inside the room for emergency calls

Interior Window Exterior Window

Cisco TelePresence Room RequirementsLighting and Acoustic Challenges

Windows in a room allow transmission of extraneous noise, light, and temperature

Windows also create exaggerated sound reverberation within a room

Address windows to prevent external factors from permeating into the TelePresence environment and to control sound reflection inside the room


Presentation_ID

Cisco TelePresence Room RequirementsLighting Requirement

Proper lighting is critical to the experience!

300-400 lux of well dispersed, horizontal, ambient light throughout the room. 4100k fluorescent bulbs with indirect fixtures; Provide 4100k color temperature light source

Minimum illumination of 250 lux is acceptable if the room is not too deep and light cove helps to light up the face;

The lighting in the room should be well controlled. It means block natural sun light or other type of office light through glass or thin blinds

Lighting source shouldn’t create any Temporal Flickering


Presentation_ID

Cisco TelePresence Room RequirementsAffects of Lighting Inconsistencies

Room with Cool Fluorescent Room with Natural Daylight Room with Incandescent

When rooms are not tuned for lighting continuity, color temperatures will vary and affect the on-camera experience

Cisco TelePresence Room RequirementsAcoustics—Room Isolation

Rooms should be isolated from other environments and not allow more than 20-30dB of sound transmit through walls. 40-60 STC and IIC recommended

Walls

Sound Transmission Class (STC)

Drywall, Cinderblock, Brick, Glass, other?

Do walls extend to structural deck?

Insulation between rooms?

Floor and Ceiling

Impact Insulation Class (IIC)

Multi-floor construction?

Raised or Plenum floors? HVAC noise should not be greater than 42dB at diffuser.

36dB and lower recommended


Presentation_ID

Cisco TelePresence Room RequirementsAcoustics—Reverberation = Echo

Noise Reduction Coefficient (NRC) Absorption of sound

Reverberation should not exceed 500 milliseconds and is ideal at 150—300ms across all frequencies (125Hz-4kHz)

Walls

Painted Drywall and Fabric Panelsrecommended. Wood, brick, block

or similar may required remediation

Floors

Carpet is highly recommended Marble, wood, and tile are highly

sound reflective

Ceiling

Acoustic tiles with high sound

absorption rating highly recommended
