Inventory and Information Model Objects (IMOs)
Technology Description
Frame Relay
Frame Relay (FR) is a high performance variable length packets switching with statistical multiplexing Data Link (Layer 2) WAN protocol, which Although originally designed for use across Integrated Services Digital Network (ISDN) interface, today it is used over a variety of other network interfaces as well.
FR networks consist of FR switches interconnected by point-to-point FR links or Interfaces and are fundamentally connection-oriented, which means that a virtual channel (VC) must be set up across the FR network prior to any data transfer.
Inventory and Information Model Objects (IMOs)
This section includes the following tables:

Frame Relay Interface
The following Data Link layer Frame Relay Interface object aggregates multiple Frame Relay Virtual Connections, which it is bound to by its VC Table attributes. It is bound by its Containing Termination Points attribute to a Physical Layer Interface, and is primarily being accessed by Data Link layer VC Multiplexer, bound by its Contained Connection Termination Points attribute. It is also being accessed by Virtual Connection Switching Entity.

Frame Relay Logical Interface
The following Data Link layer Frame Relay Logical Interface object aggregates multiple Frame Relay Virtual Connections, which it is bound to by its VC Table attributes. It is bound by its Containing Termination Points attribute to a Physical Layer Interface, and is primarily accessed by the Virtual Connection Switching Entity and Data Link layer VC Encapsulation bound by its Contained Connection Termination Points attribute.
Frame Relay Trunk Virtual Connection
The following Data Link layer Frame Relay Trunk Virtual Connection object, is bound by its Containing Termination Points attribute to a Frame Relay Interface object, and is primarily accessed by the Virtual Cross Connection and Data Link layer VC Encapsulation, however it is not bound to any of them by any of its attributes.
