Was this the receiver off hook tone for Tennessee Telephone Co. in Halls Cross Roads Tn. - Video Dailymotion  Was this the ROH tone for Tennesseee Telephone Co. in Halls Crossroads Tn.? is says that the Tennessee Telephone Co. was a switch type ATT/Philps Tel 5ESS PBX Host. Is there another Tennessee Telephone Co.? I though that the phone company was Halls Telephone Exchange Inc. and that they were ATT/Philps Tel 5ESS-PBX Host. Were there 2 phone Companies in Halls Crossroads Tn. with
that same switch? I would still like to know the Technical name for that kind if ROH tone. Please let me know. Thank you.
