Parameters
n393-value
: Sets the DCE-side N393 counter in the range of 1 to 10.
Usage guidelines
This command is available on DCE interfaces.
A DCE requires a DTE to send a status enquiry message at an interval set by the T392 timer. If the
DCE has not received the status enquiry message when the T392 timer expires, the error counter on
the DCE increments by one.
The N392 counter sets an error threshold for the total number of monitored events set by the N393
counter. If the number of errors during N393 events reaches N392, the DCE considers the physical
link and all VCs unavailable and will not use them to forward packets.
N392 must be less than N393 on the DCE side.
Examples
# Set the type of Frame Relay interface Serial 2/1/0 to DCE. Set N392 to 5 and N393 to 6.

Parameters
n393-value
: Sets the DTE-side N393 counter in the range of 1 to 10.
Usage guidelines
This command is available on DTE interfaces.
A DTE sends status enquiry messages at an interval to a DCE to request the link status. When the
DCE receives a status enquiry message, the DCE immediately sends a status message. If the DTE
has not received the status message when the T391 timer expires, the error counter on the DTE
increments by one.
