Data Restriction
Protects analog data calls from being disturbed by any of the system’s overriding or
ringing features. It is administered at the system level to selected analog and
multi-appearance telephones and trunk groups.
Administered Connections
Automatically establishes an end-to-end connection between two access or data
endpoints based on administered attributes. This feature provides capabilities such as
alarm notification, including an administrable alarm type and threshold; automatic
restoration of connections established over a Software-Defined Data Network; ISDN-PRI
trunk group [service may be referred to as ISDN-PRI (AC/AE) Service]; scheduled as well
as continuous connections; and administrable-retry interval for failed connection
attempts.
Multimedia Calling
Multimedia calls are initiated with voice and video only. Once a call is established, one of
the parties may initiate an associated data conference to include all of the parties on the
call who are capable of supporting data. The data conference is controlled by an adjunct
device called an Expansion Services Module (ESM).
Multimedia Call Early Answer on
Vectors and Stations
Early Answer is a feature applied to multimedia calls in conjunction with conversion to
voice. Early Answer:
■ Answers the data call
■ Establishes the multimedia protocol prior to completion of a converted call
■ Ensures that a voice path to/from the originator is available when the (voice) call is
answered
For an incoming call, Early Answer answers the dynamic service-link calls when the
destination endpoint answers, unless Early Answer is specified during routing or
termination processing.
