Cable ID

The name of one physical cable, such as TV-2.1, which closes up while numbers are unlocked and is its cable's for good once they are locked.

A Cable ID names one physical cable, for the label on it and the row in the cable schedule. It comes from its icon's Number and the cable's place: an icon's two Cat6 cables are TV-2.1 and TV-2.2. A pair's shared cable takes the entry speaker's Number (SP-3.1). A cable group's cables belong to the group: LINK-1.1 the run, LINK-1.2 the spare, LINK-1.3 between members; a 70V line's run and each piece of its chain, 70V-A.1, 70V-A.2. Adding a speaker in the middle of a line makes two new pieces; every other piece keeps its ID. A surround speaker takes its system and role (S1-FL), and a surround pair's shared cable the entry speaker's (S1-FL.1).

It is made when the cable first appears. A pair's Cable ID never carries its L or R, so swapping its sides never leaves a wrong label on a pulled wire; a surround pair, whose roles are its sides, has no swap.

While the project's numbers are unlocked, Cable IDs close up on their own when a cable is deleted, as device Numbers do. Once they are locked, an ID is its cable's for good and never passed to another: a removed ID shows in brackets, a new cable takes the next one, and Renumber cables starts them afresh in a new version. Each version keeps the Cable IDs it issued.
