Parameters
n393-value: The value of N393 parameter at the DTE side. It ranges from 1 to 10.
Description
Use the fr lmi n393dte command to set N393 parameter at the DTE side.
Use the undo fr lmi n393dte command to restore the default.
By default, the parameter value is 4.
The DTE sends a Status-Enquiry message at a regular interval to the DCE to inquire the link status. On
receiving this message, the DCE will immediately send a Status message. If the DTE does not receive the
Status message 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 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 count had exceeded the
threshold and declare the physical channels and all DLCIs to be unavailable.
N392 at the DTE side should be less than N393 at the DTE side.
