Abstract

Situations can arise where a number of people may want to hear the same information over the phone at the same time. To do this in a conventional manner requires that special hardware is installed in a switch; a number of Public Telephone Service Providers (PTTs) use such hardware to provide a "many-to-many" conferencing facility.

Transmitting Telephone Information to Multiple Listeners

      Situations can arise where a number of people may want to hear
the same information over the phone at the same time.  To do this in
a conventional manner requires that special hardware is installed in
a switch; a number of Public Telephone Service Providers (PTTs) use
such hardware to provide a "many-to-many" conferencing facility.

      Many-to-many conferencing allows any of the conferenced
participants to participate in the conference call.  This may not be
desirable for some types of application where a "listen-only"
facility is required, for example where a conferenced telephone
conversation between 2 or more contributing people is listened to by
1 or more other people.  A typical recent requirement for the Voice
Response Unit (VRU) product, Direct Talk/6000*, called for 90+
"listeners" and a 2-person conferenced call as the audio source.

      Such a requirement may be met by causing the VRU system to be
conferenced-in by the switch to the source of the audio information.
The VRU system could then be made to receive this information off one
line and transmit it simultaneously to many lines connected to
"listeners."

      The "listeners" would call into the VRU system to be connected
to the source of the audio information in a "listen-only" mode.  This
approach could also be used where a single person is the source of
the audio information i.e., A "one-to-many" announcement system.
