The following are sounds from preserved step by step switches by a private collector in Mattoon, Illinois. The switches are connected to the regular phone network where an outside person can call in and using Touch Tones can make calls on the switches.
The following switches are represented here:
682 prefix: FTR-Kellog (later ITT Kellog)
FTR (Federal Telephone and Radio) central office (later Kellog, still later ITT-Kellog, and finally ITT when they ceased manufacturing) from 1953. The switch closely resemble the Automatic Electric style.
486 (IVanhoe) Prefix: Stromberg-Carlson XY
375 Prefix: Automatic Electric
FTR-Kellog Switch (682 Prefix)
Recordings were made in November 2002. At the time these were made, the call-in adapter was on this switch.
(Note – The faint MF tones you hear are from the AT&T pre-paid calling card platform that I used when I was making these recordings)
Stromberg-Carlson XY Switch (486 Prefix)
Recorded in November 2006. At the time these were made, the call-in adapter was on this switch.
1000 Hz Tone
