Notation that describes line card redundancy, where N is the number of installed line cards of a single card type and 1 is an additional line card of that type designated as a standby card. For example, if you have three T-ONE cards and one additional standby T-ONE card installed, the system provides redundancy by activating the standby card if any of the three active T-ONE cards fail.
