Automatic Electric Step by Step Recordings

GTE (now Verizon) phased out the last of their Automatic Electric step by step phone switch equipment in the late 1990s. These recordings were recorded in the summer of 1997, except where noted. 

Dial Tone
Dial tone from Deland, Illinois - (217) 664 prefix.

Busy Signal
Busy signal from Phillipsburg, Ohio - (937) 884 prefix.

Reorder (fast busy signal) from Long Point, Illinois - (815) 854 prefix.

Ringback Signal
Ringback signal from Honanunau, Hawaii - (808) 328 prefix.

1000Hz Test Tone
An example of a 1000Hz test tone (sometimes called milliwatt tone) from Kingston, MI - (517) 683 prefix.

Busy Signal #2
This is a busy signal from Bettsville, OH - (419) 986 (April 1998). It starts out as a ring, then goes into a "busy" signal. I assume it may be a test number.
