LMI configuration relates to the periodic polling that is performed between pairs
of Frame Relay devices to determine the status of PVC connections and to verify
the link integrity. This polling is done through a procedure known as
Status
Enquiry
. Two types are polling are performed: full status (FS) and link integrity
verification (LIV). Full status polling also includes link integrity verification.

,
q.933a
,
or
t1.617d
.
Procedure
—Specifies whether the PathBuilder S600 will be designated as the
user-side, the network-side, or bidirectional in the period polling performed
between frame relay devices.
User LIV Polling Timer (T391)
—The time interval (in seconds) at which Status
Enquiry occurs for link integrity verification (LIV) polling:
5..180
. This parameter
applies only when the PathBuilder S600 is designated as the user side unit.
Set this parameter at a higher value than the
Network PV Timer
parameter on the
network side unit.
Network PV Timer (T392)
—Network Polling Verification Timer. When the unit is
configured as the network side unit, the user-side unit sends the Status Enquiry
request. The Network Polling Verification acts on the user initiated-request and
checks whether or not it has any new information to report, based on the
specified timer.
User FS Polling Counter (N391)
—The time interval (in seconds) at which Status
Enquiry occurs for full status (FS) polling:
