ABSTRACT:
A packet transmission arrangement maintains a certain minimum bandwidth for a call. When a silence period is detected, the bandwidth that is allocated to the call is reduced. When a speech period is detected, the reduced bandwidth remains in force, unless there is spare capacity, in which case a full measure of bandwidth is allocated to the call.
