Data and Voice
C-2
Note
Some ISDN service providers might charge a lower rate for an ISDN line that
supports only data applications. If you do not require voice capability on your ISDN line,
provision the line for data application support only.
Table C-1 describes the data and voice application features.
Table C-1 ISDN BRI Data and Voice Applications
Feature Description
Subaddressing Provides locally addressed terminals within a
specific ISDN access area.
Speech/3.1-kHz audio-bearer capability Enables use of terminal equipment that supports
voice applications. Examples of this type of
equipment are ISDN telephones and terminal
adapters.
Multiple subscriber numbers (MSN) Enables the use of multiple directory numbers on
the same ISDN line. Each piece of terminal
equipment on the same ISDN line can then be
assigned its own directory number.
Call hold and retrieve Enables a call in progress to be put on hold and
then retrieved.
Call waiting During a voice call, enables the call waiting tone to
be generated when a second voice call is received.
Call bumping When two data calls are in progress and ACO is
provisioned on the ISDN line, the router can be
configured to either ignore a voice call or
disconnect a data call to accept the voice call. (Also
referred to as voice priority.)
Call transfer Transfers an active call to another telephone
number.
3-way call conferencing Adds a third party to an existing call.
