Description
Use the fr lmi n392dce command to set N392 parameter at the DCE side.
Use the undo fr lmi n392dce command to restore the default.
By default, the parameter value is 3.
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 within a period of time, the error counter on DCE increments
by one. 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
reaches 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 should be less than N393 at the DCE side.
Examples
# Set frame relay interface Serial 4/1/8:10 to operate in DCE mode and set N392 to 5 and N393 to
6.

Parameters
n392-value: The value of N392 parameter at the DTE side. It ranges from 1 to 10.
Description
Use the fr lmi n392dte command to set N392 parameter at the DTE side.
Use the undo fr lmi n392dte command to restore the default.
By default, the parameter is 3.
The DTE sends a Status-Enquiry message 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.
