Description The DCE requires the DTE to send a Status-Enquiry packet at a regular interval (set by
T392). If the DCE does not receive the Status-Enquiry packet, it will record the error by
adding 1 to the error count. If the errors exceed the threshold, the DCE would
consider the physical channels and all the DLCIs to be unavailable.
N392 and N393 together define the “error threshold”. N393 defines the event
number observed and N392 defines the error threshold of that number (N393). That
is, if the number of errors that occurred to the DCE reach N392 in N393 events, DCE
will consider the errors have reached the threshold and declare the physical channels
and all DLCIs to be unavailable.
N392 at DCE side should be less than N393 at DCE side.
