Voatm meaning

Referring to voice communications over an ATM network. Uncompressed VoATM traffic is constant bit rate (CBR) traffic based on pulse code modulation (PCM) and time division multiplexing (TDM). CBR traffic requires the presentation of time slots on a regular and unswerving basis. Compressed voice is variable bit rate (VBR) traffic and requires access to time slots at a rate that can vary dramatically from time to time. See also ATM, CBR, PCM, TDM, and VBR.
