Night exchange · one shift · no queue

A Small Exchange

Patch a ringing call into a free shared trunk. Direct trunks hold a line; a warm relay clears a follow-up faster and pays two extra marks. Cut only when the line you save is worth the loss.

Ringing lines

Choose a call, then a free trunk.

The tape remembers

The handover is already on the tape. The first bells are ringing.

Keyboard: Tab and Enter work throughout; 1, 2, or 3 patches the selected line. In reduced-motion mode, press Space to advance the clock. The desk stops itself when its tab is hidden.

This desk needs its local script to operate. It does not rely on a connection.
