ACE
See Cisco Application Control Engine (ACE).
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.
active/active
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.
active/standby
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.

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.
R
region
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.
