All VCs are returned to the pl state (sea pl state READY explanation) and
all PVCs are returned to dl, (flow control ready) state.
The DCE returns each VC to the pl state (see pl state explanation) and
issues a restart confirmation packet to the DTE.
The DCE returns each VC to the pl state (see pl state explanation) and
issues a restart indication packet to the DTE.
Release all resources assigned to VC channel.
Determine if sufficient resources exist to support request; if so, allocate
resources and forward IS0 8208 call request packet to IWF; if not, enter
DCE clear indication to DTE state (p7). Determination of resources and
allocation is as defined in IS0 8208.
Determine if sufficient resources exist to Support request; if so, allocate
resources and forward IS0 8208 incoming call packet to DTE; if not, send a
clear request packet to the IWE Determination of resources and allocation is
as dcfined in IS0 8208.
~4 DATA TRANSFER No action.
~5 CALL COLLISION Send a clear request packet to the IWF, corresponding to the incoming call
packet (the DTE in its call collision state ignores the incoming call), and
proceed with the DTE call request packct.
~6 DTE CLEAR Release all resources assigned to VC channel. Send an IS0 8208 clear
REQUEST confirmation packet to the DTE, a clear request packet to the IWF, and enter
pl state.
~7 DCE CLEAR Forward IS0 8208 clear indicatian packet to DTE.
