LMI describes a protocol and associated procedures operating on the local interface between the user and the network. It notifies the user of the addition, deletion, and presence of the PVC in the network. It also notifies the user of the end-to-end availability or unavailability of a PVC. Basic LMI protocol is based on a synchronous polling scheme where the user polls the network to obtain status information on the PVCs configured on the interface. LMI simply augments the ANSI/CCITT standard Frame Relay protocol and in no way interferes with the normal operation of user PVCs on the interface.

Annex D provides additional procedures for permanent virtual connections using unnumbered information frames. Annex D describes the means for notification of outage of a permanent virtual connection and recovery from such a condition. This follows the ANSI T1.617 standards.

Annex A provides additional procedures for permanent virtual connections using unnumbered information frames. Annex A describes the means for notification of outage of a permanent virtual connection and recovery from such a condition. This follows the ITU-T Q.933 standard

Encapsulation Type

The Encapsulation Type depends on the type of device that is connected at the other end of the trunk. If another MultiFRAD 100 is connected at the other end of the trunk, then the Mux mode is used. If a non-MultiFRAD 100 is at the other end of the trunk, then the Raw mode is used.

Management Parameters

Polling Interval

The Polling Interval defines a time period in which a status enquiry message is sent from the MultiFRAD to the network. The Status Enquiry message requests the status of the PVC(s) or verification of the status of a physical link. When the Status Enquiry message is sent by the MultiFRAD, the Polling Interval is restarted. The network responds with a status message that reports the status of the PVC or verifies the integrity of the physical link. The polling interval is 5 to 30 seconds with a default of 10 seconds.
