Description The DTE sends a Status-Enquiry packet at a regular interval to the DCE to inquire the
link status. On receiving this packet, the DCE will immediately send a Status-Response
packet. If the DTE does not receive the response packet in the specified time, it will
record the error by adding 1 to the error count. If the errors exceed the threshold, the
DTE will consider that the physical channels and all the DLCIs to be unavailable.
N392 and N393 together define the “error threshold”. N393 indicates the event
number observed and N392 indicates the error threshold of that number (N393). That
is, if N392 errors occurred in N393 Status-Enquiry packets in the DTE, the DTE would
consider that the error had exceeded the threshold and declare the physical channels
and all DLCIs to be unavailable.
N392 at DTE side should be less than N393 at DTE side.
