Typical Application Scenarios

You can use frame relay to construct a public or private network, as shown in
direct connections between data equipment, as shown in

Default
value
Sets the frequency with which status inquires
expect a full status report.
Suppose the N391 is set to 5. Every fifth status
6
inquiry sent by the DTE will ask for a full status
report. The intermediate inquiries ask for a
keepalive exchange only.
Sets the number of errors required for LMI to
3 declare a link dead, within the event count
specified by N393.
Sets the monitored event count. If the number of
errors within the N393 status inquiries reaches
4
N392, the DTE considers that the error
threshold is reached.
Sets the interval (in seconds) at which the DTE
sends a status inquiry message. An error is
10
recorded if no reply is received before the timer
expires.
Sets the number of errors required for LMI to
3
declare a link dead, within the event count
specified by N393.
4 Sets the monitoring interval for error counts.
Sets the interval (in seconds) for receiving a
status inquiry message. If no status inquiry
15
message is received before the timer expires,
an error is recorded.
