access control list (ACL)
Feature that filters incoming or outgoing traffic based on a set of rules that are applied to specified fields in the messages. You can configure an ACL on an incoming or outgoing interface. You can allow or deny traffic based on criteria such as the source and destination IP addresses and port numbers.
Redundancy configuration in which two units actively participate in the system during normal operation. If one unit fails, the workload of both units is processed by the remaining active unit. A load balancer may be used to facilitate active/active redundancy. See also load balancer.
Redundancy configuration in which the primary unit actively participates in the system and the secondary unit remains in standby mode. If the primary unit fails, the secondary unit becomes active.
ad hoc meeting
A meeting that begins immediately (in contrast to a scheduled meeting, which starts at a future time).
admin context
On the ACE, you can define a single context or multiple contexts. By default, the ACE creates a single context named the admin context. Multiple contexts use virtualization to partition the ACE into multiple virtual devices. Each context can contain its own set of policies, interfaces, resources, and administrators.
administration console
Provides a graphical user interface for provisioning and monitoring the Cisco TelePresence Exchange System.
administration server
Provides the application programming interface (API) and the administration console for the Cisco TelePresence Exchange System.
A user role that has access to all setup, configuration, and monitoring functionality in the administration console. This role can add or modify API users (but only the system administrator role can add or modify other administrator users).

media resources
Cisco platforms that provide capabilities for the media data path (such as multipoint switching or interactive voice response) or the media control path (such as session border controller). Media resources are grouped into clusters at a region. A resource cluster (also known as a resource pool) is a connected set of resources in one physical data center and is also known as a point of presence (POP). See also session border controller (SBC).
Meet-Me service
Rendezvous conference service in which the participants join the meeting by using a pre-arranged meeting ID. The Cisco TelePresence Exchange System provides business-to-business telepresence services.
multipoint meeting
Requires a Multipoint Control Unit (MCU) to combine or switch the media streams of the meeting participants. A multipoint meeting generally includes more than two participants.
Multipoint Control Unit (MCU)
Network element that provides features for multipoint meetings. For example, the MCU can combine media streams and switch media streams between participants. The Cisco TelePresence Multipoint Switch is an example of an MCU.

A single physical server in the server cluster. See also administration server, call engine server and database server.

A business customer served by a service provider. An organization controls one or more telepresence rooms (also known as endpoints) that can be included in a meeting. An organization can choose hosted endpoint service or enterprise endpoint service. See also hosted endpoint service and enterprise endpoint service.
organization ports management
An optional feature that allows each organization to control the number of organization ports that are consumed by telepresence traffic on the network between the organization and the Cisco TelePresence Exchange System.

perpetual license
Permanent license that is installed on a Cisco TelePresence Exchange System and that has no expiration date. See also license.
point of presence (POP)
Physical location of service provider resources. For the Cisco TelePresence Exchange System, the service provider POPs are data centers that house media resources (such as a Cisco TelePresence Multipoint Switch or Cisco TelePresence MSE 8000 Series) and call control resources (such as SBC).
point-to-point meeting
A meeting between two Cisco TelePresence endpoints that does not require an MCU.
provisioned endpoint
Endpoints for which all configuration details (such as name, phone number, number of screens, and organization) are known by the administrator and configured on the Cisco TelePresence Exchange System. Meet-Me and direct dial calls are placed on provisioned endpoints. If an organization has chosen hosted endpoint service, the endpoints are provisioned endpoints.

Represents a major geographic area in which a service provider operates. All media resources in a region are considered to be equivalent for resource allocation purposes.
remote endpoints
Endpoint for which no configuration details are known. Remote endpoints are endpoints that join the meeting from another service provider network. Configuring a remote endpoint on the Cisco TelePresence Exchange System reserves capacity for the endpoint on the service provider network on which it resides. The Cisco TelePresence Exchange System automatically determines and reserves the capacity to support these interprovider meetings.
remote meeting
A remote meeting uses media resources hosted by a remote Cisco TelePresence Exchange System. You schedule a remote meeting to provide One-Button-to-Push (OBTP) functionality to the provisioned endpoints.

scheduled meeting
A meeting that starts at a future time. The meeting host contacts the designated scheduler to reserve the meeting. A scheduled meeting can be a multipoint meeting or a point-to-point meeting. See also multipoint meeting.
A unit of capacity. A segment represents one screen of video transmission. See also capacity.
server cluster
A group of physical servers. The Cisco TelePresence Exchange System is a six-node cluster composed of two database servers, two administration servers, and a minimum of two call engine servers. See also database server, administration server and call engine server.
service provider
An entity that offers telepresence services to a set of business customers (organizations) by using media resources that are provisioned in one or more regions of their network.
session border controller (SBC)
Located at the border of a network. The SBC controls call admission to the network and protects the network from excessive call load and malicious traffic. It also provides media bridging.
The SBC includes signaling functionality managed by the Signaling Border Element (SBE), and media functionality managed by the Data Border Element (DBE). The SBC can operate in a unified or distributed deployment model. In the unified model, the SBE and DBE coexist on the same network element. In the distributed model, the SBE and DBE reside on different network elements.
session initiation protocol (SIP)
A text-based call control protocol intended for creating, modifying, and terminating sessions with one or more participants. Cisco TelePresence employs SIP as the call control protocol.
standing meeting
A meeting that remains active until you delete it.
static meeting
A meeting that is permanently available. Each static meeting has its own associated meeting number, and meeting attendees dial that number to join the meeting.
A load balancer feature. Stickiness ensures that all messages related to one session are directed to the same server. See also load balancer.
system administrator
A user role that can assign roles to all users and has unrestricted access to configure and modify all settings in the Cisco TelePresence Exchange System.

TelePresence Interoperability Protocol (TIP)
Specialized protocol used by some Cisco TelePresence endpoints to provide advanced features such as multi-screen calling and spatial audio.
two-party direct
A call that is a point-to-point meeting between two provisioned endpoints in the same organization. One participant initiates the meeting by direct dialing the other participant. A two-party direct call can be scheduled or ad hoc.

Unified CM
unprovisioned endpoint
Endpoint for which no configuration details are known by the administrator except the name of the meeting scheduler for that endpoint. You configure an unprovisioned endpoint on the Cisco TelePresence Exchange System to reserve bandwidth for the endpoint on the service provider network. This allows the endpoint to connect with other known endpoints within the network that are scheduled for the same meeting. This capability is useful for intercompany meetings.

volume-based license
License that sets a limit on the number of active concurrent sessions (Cisco TelePresence meetings) that can be supported. Volume-based licenses are offered in various quantities to match the call processing requirements of the network.
