Q. In ATM, the _________ class is designed for customers who need real-time audio or video services. The service is similar to that provided by a dedicated line such as a T line.

View solution

Q. In ATM, the _________ class is divided into two subclasses: real-time (VBR-RT) and non-real-time (VBR-NRT). VBR-RT is designed for those users who need real-time services (such as voice and video transmission) and use compression techniques to create a variable bit rate. VBR-NRT is designed for those users who do not need real-time services but use compression techniques to create a variable bit rate.
