and (for X.25) some of the processor channel pairs are incomplete
(remote channel not specified, meaning that the processor channels are
not connected), then look at the status of "status processor-channel" for
the local processor channels that are not connected.
2. Look for active PI-SCI alarms and follow the procedure for those alarms if
there are any. If there are no PI-SCI problems, go on to the next step.
3. If the link is still down, restart the link via the busyout link lnk-no system
technician command followed by the release link lnk-no command. This
sequence tears down the call and then tries to bring it back up. If the link
