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 number of events observed
and N392 indicates the error threshold for that number (N393). If N392 errors occurred in N393
Status-Enquiry messages 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 the DTE side.
Examples
# Set the operation of frame relay interface Serial 4/1/8:10 as the DTE mode and set N392 to 5 and
N393 to 6.

Parameters
n393-value: The value of N392 parameter at the DTE side. It ranges from 1 to 10.
Description
Use the fr lmi n393dce command to set the N393 parameter at the DCE side.
Use the undo fr lmi n393dce command to restore the default.
By default, the parameter value is 4.
The DCE requires the DTE to send a Status-Enquiry message at a regular interval (set by T392). If the DCE
does not receive the Status-Enquiry message, 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 number of events observed and
N392 defines the error threshold for that number (N393). 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 the DCE side.
