It ranges from 1 to 10.DescriptionUse 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. Onreceiving this message, the DCE will immediately send a Status message. If the DTE does not receive theStatus message in the specified time, it will record the error by adding 1 to the error count. If the errorsexceed the threshold, the DTE will consider that the physical channels and all the DLCIs to beunavailable.N392 and N393 together define the “error threshold”. N393 indicates the number of events observedand N392 indicates the error threshold for that number (N393). If N392 errors occurred in N393Status-Enquiry messages in the DTE, the DTE would consider that the error count had exceeded thethreshold 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.Examples# Set the operation of frame relay interface Serial 4/1/8:10 as the DTE mode and set N392 to 5 andN393 to 6. system-view[Sysname] interface Serial 4/1/8:10[Sysname-Serial4/1/8:10] link-protocol fr[Sysname-Serial4/1/8:10] fr interface-type dte[Sysname-Serial4/1/8:10] fr lmi n392dte 5
