Parameter 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 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 occur 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 at DCE side should be less than N393 at DCE side.

Example # Set the operation of frame relay interface Serial 2/0 as DCE mode and set N392 to 5 and N393 to 6.
