Parameter
n393dte-value : LMI event counter value on a DTE, ranging 1 to 10. The default value is
4.
Description
Using the fr lmi n393dte command, you can configure the LMI event counter value on
a DTE. Using the undo fr lmi n393dte command, you can restore the default value.
The DTE sends a Status-Enquiry packet at a regular interval (set by T392) to the DCE
to inquire the link status. On receiving this packet, the DCE will immediately send a
Status-Response packet. If the DCE does not receive the acknowledgement in the
specified time, it will record the error by adding 1 to the error count. If the errors reach
the threshold, the DTE will declare that the physical channels and all the DLCIs to be
down.
N392 and N393 together, define the “error threshold”. N393 indicates the event count
observed and N392 indicates the error threshold in the event count observed. That is, if
N392 errors occur to N393 Status-Enquiry packets in the DTE, the DTE would consider
that the error count reached the threshold and declare the physical channels and all
DLCIs to be down.
N392 should be less than N393.
