CES services, user CBR data received from an edge device at one side of the network is segmented into
ATM cells and propagated through the ATM network. After traversing the network, the ATM cells are
reassembled into a CBR bit stream that matches the original user data. This CBR data is then passed out
of the network to the edge device at the destination endpoint.
