Voice over Asynchronous Transfer Mode (VoATM) is a data protocol used to transport packetized voice signals over an Asynchronous Transfer Mode (ATM) network.
[1] VoATM is a multi-service, high speed, scalable technology but rarely found because of its expensive services.
[3] Fragmentation is built into ATM with its small, fixed-sized, 53-byte cells.
[3][4] Dynamic Bandwidth Circuit Emulation Service (DBCES) does not send a constant bit stream of cells but transmit only at an active voice call, reducing delays and variations.
[3] VoATM transports data, voice, and video at very high speed.
