A method and apparatus for automatically establishing a set of calls in a network is presented. A first device determines a maximum number of simultaneous calls that can be processed by a second device. The first device then determines a time interval necessary to allow calls to be established in a set of channels associated with the second device. Using the maximum number of simultaneous calls and the time interval previously determined, the set of calls are established.

Automation of call setup in IP telephony for tests and measurements

A method and apparatus for measuring call setup time is presented. A first device in a network sends a signal to a second device. The first device monitors for a response from the second device and adjusts an answer tone setting for the second device based on the response. After which, the first device calculates an elapsed time between sending the signal and a receipt of the response.

Apparatus and method for call progress timing measurement in IP telephony

A method and system for transmitting a video stream in an asynchronous transfer mode (ATM) network comprises steps of encoding the video into an MPEG-2 variable bit rate video stream, shaping the encoded variable bit rate video stream to conform to the traffic contract parameters for a Variable Bit Rate (VBR) connection in the network, and transmitting the shaped variable bit rate video stream on the VBR connection based on the traffic contract parameters. For a given network bandwidth, switch buffer space, and equivalent video quality, the network can statistically multiplex a larger number of variable bit rate video streams by maximizing the utilization of the network bandwidth and switch buffer space that the network allocates to each video stream.
