This object provides a human-readable, CLI-consistent description of the circuit an IP interface is bound to, formatted as slot/port:channel:subchannel followed by an authority/level/index, with channel and subchannel segments only appearing when relevant. An administrator reads this to quickly identify, in the same terms used at the command line, exactly which physical circuit underlies a given IP binding entry. An example value given directly in the source is "4/1:1 1/2/7", describing a circuit on slot 4 port 1, channel 1.
