- data circuit-terminating equipment
DCE is used to provide clocking to DTE equipment.
- data compression
- data direct VCC
A bidirectional point-to-point virtual control connection (VCC) set up between two LECs in ATM and one of three data connections defined by Phase 1 LAN emulation. Because data direct VCCs do not guarantee QoS, they are generally reserved for UBR and ABR connections. Compare with: control distribute VCC and control direct VCC.
- data encapsulation
The process in which the information in a protocol is wrapped, or contained, in the data section of another protocol. In the OSI reference model, each layer encapsulates the layer immediately above it as the data flows down the protocol stack.
