Network Clock Services for CES Operations and CBR Traffic
Circuit emulation services-interworking functions (CES-IWF) and constant bit rate (CBR) traffic relate
to a quality of service (QoS) classification defined by the ATM Forum for Class A (ATM adaptation
layer 1 [AAL1]) traffic in ATM networks. In general, Class A traffic pertains to voice and video
transmissions, which have particular clocking requirements. For details, refer to Chapter 18,
“Configuring Circuit Emulation Services.”
