Chapter 1 | About Scopia TIP Gateway
The Scopia TIP Gateway allows organizations to connect Cisco telepresence rooms directly to a Scopia Elite MCU
conference and view all three screens of the Cisco telepresence system.
The TIP Gateway is used for making video calls from the Scopia Elite MCU to Cisco Telepresence rooms and vice
versa. Without the TIP Gateway you see only the active speaker on the endpoint screen. With the TIP Gateway you
see all the participants on the screens, giving the full telepresence experience. With a Scopia TIP Gateway deployed
into your existing Scopia Solution, Cisco telepresence rooms become an integral part of your deployment.
Figure 1: TIP Gateway functionality on page 6 illustrates this functionality, whether the TIP Gateway is located in
an enterprise or hosted in a service provider’s network.
Figure 1: TIP Gateway functionality
The main features of the TIP Gateway include:
•TIP protocol support
Cisco telepresence rooms can connect to a Scopia Elite MCU conference and enjoy a comprehensive
experience including audio, video and content sharing.
Scopia Elite MCU provides video layouts that were designed specifically for telepresence rooms to maintain the
telepresence experience in the best possible way.
•Scheduling
Cisco Telepresence rooms can be included in a scheduled Scopia Management meeting like any other
endpoint.
•Scalability
The TIP Gateway is designed to grow with deployment requirements from a small workgroup to an entire
enterprise. Unlimited scalability is achieved by simply stacking multiple gateways.
For more information on the TIP Gateway, see Planning your Topology for the TIP Gateway on page 9.

•Planning your Topology for the TIP Gateway on page 9
•Creating Dial Plans for Cisco Telepresence on page 10
•Ports to Open on the Scopia TIP Gateway on page 11
Planning your Topology for the TIP Gateway
Deploying the Scopia TIP Gateway requires configuring the unit itself as well as several other
components.
Depending on the deployment, the setup is composed of these mandatory components:
•TIP Gateway
•Scopia Management
•Scopia Elite MCU for housing telepresence meetings with multiple endpoints, both H.323 and SIP.
•H.323/SIP endpoints
•CUCM (Cisco Unified Communications Manager). This is the central communication server for all
Cisco related products.
•Cisco Telepresence Systems. These include single-presence CTS-500/1000 Series and triple-
presence CTS-3000 Series.
Other optional components typically include:
•CTMS (Cisco Telepresence Multipoint Switch), which is the Cisco MCU
•CTS-Manager, Cisco's application for scheduling meetings.
Figure 2: Deploying the TIP Gateway in the enterprise on page 10 describes a typical deployment of
the TIP Gateway.
Deployment Guide for Scopia TIP Gateway Version 8.2 Planning your TIP Gateway Deployment | 9

Figure 2: Deploying the TIP Gateway in the enterprise
Creating Dial Plans for Cisco Telepresence
All telepresence calls are made through the Scopia Elite MCU. Users of telepresence deployments do
not need to choose a specific MCU. The powerful functionality of virtual rooms enables you to dial the
same number anywhere in the world while the Scopia Solution infrastructure transparently directs you to
the correct telepresence conference.
For information on the devices that are part of the telepresence deployment, see Planning your
Topology for the TIP Gateway on page 9.
Important:
Cisco routing patterns are configured only by the personnel that installed the Cisco services or by the
customer's network administrator.
Cisco Telepresence Systems can dial into a telepresence conference as follows:
•By dialing directly into to the Scopia Elite MCU via Scopia Management.
For example, a routing pattern might define the dial prefix ‘5’ to route the call to the Scopia
Management. Dialing the number 5-1234 would send the number 1234 to the Scopia
Management.
•By dialing through the CTMS in organizations that use this Cisco MCU in their deployment.
Standard endpoints can dial into a telepresence conference as follows:
•By dialing directly to the Cisco Telepresence Systems.
For example, to call the CTS, you would dial '3003' which is the phone number the Cisco network
administrator has allocated to the device.
•By dialing through the CTMS.
Deployment Guide for Scopia TIP Gateway Version 8.2 Planning your TIP Gateway Deployment | 10

For example, an endpoint would dial 227-5678, where the dial prefix '227' routes the call to the
Cisco telepresence and '5678' is the relevant service on the CTMS as allocated by the Cisco
network administrator.
Ports to Open on the Scopia TIP Gateway
The Scopia TIP Gateway is typically deployed in the enterprise network. When opening ports on the
device, use the following as a reference:
•If you are opening ports that are both in and out of the gateway, see Table 1: Bidirectional Ports to
Open on the Scopia TIP Gateway on page 11.
•If you are opening ports inbound to the gateway, see Table 2: Inbound Ports to Open to the Scopia
TIP Gateway on page 12.

There are some critical requirements that you must meet when choosing a rack and before mounting the
device into it.
Navigation
•Choosing the Type of Rack on page 15
•Making Space for the Scopia TIP Gateway on page 15
Choosing the Type of Rack
There are many types of racks on the market. The installation instructions in this guide are intended for a
19” rack.
•Verify that the 19” rack meets the EIA-310 standards. This standard includes precise definitions of
the shape of the holes, their size, the depth of the rack and other features. For more information on
the EIA-310 standard, see http://electronics.ihs.com/collections/eia/index.htm
•Notice that the vertical square holes on the rack posts are not spaced equally. They form a
repeating pattern of two holes close together, then one hole separate, then two holes close
together and so on. See Figure 4: Hole distribution on 19” rack on page 15.
Figure 4: Hole distribution on 19” rack
Making Space for the Scopia TIP Gateway
When checking for an empty space to setup the device, be aware of its physical dimensions.
Deployment Guide for Scopia TIP Gateway Version 8.2 Preparing the Scopia TIP Gateway Setup | 15

•Install the device in an open rack whenever possible. If installation in an enclosed rack is
unavoidable, ensure that the rack has adequate ventilation.
•Avoid placing the device in an overly congested rack or directly next to another equipment rack.
Otherwise, the heated exhaust air from other equipment can enter the inlet air vents and cause the
device to overheat.
•Maintain a minimum clearance of 3 inches (7.62 cm) on the left and right of the device for the
cooling air inlet and exhaust vents.
•Find a space on the rack which is at least 7 empty square holes in height on the rack posts.
The Scopia TIP Gateway takes up 3 holes (1U) on the posts. You need at least 2 additional holes
to slide the device into the rack.
See Figure 5: Height of the Scopia TIP Gateway in the rack on page 16.
