Household line discipline card
Representative practice, 1993–1999
Observed surface
BEFORE CONNECTING — tell everyone who can reach a telephone.
DURING NEGOTIATION — do not lift a receiver to check whether the line is busy.
AFTER CONNECTION — treat silence as use, not availability.
Implied procedure
The card would be placed near the shared telephone, where a rule could substitute for a second line.
A failed call meant listening again, redialling again, and possibly finding the remote service engaged.
Interpretive residue
The network boundary passed through the household. A family member could interrupt a protocol without seeing the computer.
The warning turns connectivity into domestic coordination rather than a private machine state.
