Answer: B and D
SVCs are virtual circuits that are dynamically established
on demand and terminated when data transmission is complete.
PVCs are permanently established virtual circuits. They
always operate in one of two operational states: data
transfer or idle. Even if it is in idle state, the
connection between DTE devices is still active. SVCs and
PVCs don?t use the same circuit because PVCs have constant
virtual-circuit availability and SVCs terminate the circuit
when data transmission is complete. SVCs consist of four
operational states: call setup, data transfer, idle, and
call termination.
