Metric logic is operatively coupled with the link-layer interfaces to calculate a metric value for each link-layer interface in the set.

Each further connection interface is formed by a bracket (130, 140) for connection of a ball joint.

The proximate end of the plunger has a first mechanical linkage interface (720).

In the best mode, the interface is an IEEE 1394b interface with a physical layer interface and a link layer interface.

The Media Interworking Module provides the connection and media match between the uplink Signalling Interface Function Module and the downlink Signalling Interface Function Module.

The second interface transmits the symbols on the second communication link.

The bonding layer (14) has a bonding interface (15) at a boundary between the bonding layer and the board-like members (11, 12).

The digital data interface device may include an MDDI link controller.

The indication is received over an air interface other than the communication link.

A second interface is configured to communicate with an operably linked server.

The housing has a connecting interface for being mounted on the valve.

The seal assembly may contact the first link at a seal-link interface.

A broadband user access device includes an up interface and at least an up channel and a down channel.

Each interface is equipped with a link failure detection logic (24, 132).

An input section of an RF interface is shown in conjunction with a tuner circuit.
