from FB group Bell Telephone of… Jul 09 Jon Guidry (new member) I was a telecomm/datacomm tech for Santa Ana College and the rest of the college district, so we were a customer of Pac Bell/SBC/at&t. I did all house Telecom and datacomm wiring and plant for 3+ decades. I was a craftsperson like many

from FB group Bell Telephone of… Apr 21 Jim Engle One time I was connecting up a POTS modem line and I was getting the crossconnect wire into the 66 block ready to punch them down. BRZZAP! I got zapped by the AC! Some idjit plugged a three prong plug into a 2 prong ungrounded
