3.3. Link Dead (physical-layer not ready)
The link necessarily begins and ends with this phase. When an
external event (such as carrier detection or network administrator
configuration) indicates that the physical-layer is ready to be used,
PPP will proceed to the Link Establishment phase.
During this phase, the LCP automaton (described later) will be in the
Initial or Starting states. The transition to the Link Establishment
phase will signal an Up event to the LCP automaton.
Implementation Note:
Typically, a link will return to this phase automatically after
the disconnection of a modem. In the case of a hard-wired link,
this phase may be extremely short -- merely long enough to detect
the presence of the device.
