The Number 1 Crossbar ANI-B equipment will perform a calling directory number lookup on all outgoing long distance calls (for instance, to Phreaknet). This lookup happens after the 7 digit MF outpulsing by the subscriber sender. A momentary 5800 hz tone is placed on the sleeve lead, followed by an MF spill of the calling number. Even though the 5800 hz tone is audible on historic recordings, it is not audible at the museum (for now), because the short lengths of our trunks do not provide enough inductive coupling for this kind of artifact to come through. At some point, I'll build some artificial lines to make the tone audible.
If ANI lookup fails for any reason, you will be directed to an Phreaknet TSP operator for number identification.
