Not going to say all the blame should go to the local guys. I remember being told by our manager, shortly after TT took over, that in order to try and save money, to go into all my CO's and turn the GEN RUN schedule off in all my transfer switches. We were told that no more weekly exercises, that it would be monthly if it was a manned site, quarterly for unmanned.
Also, upper management has the mind set that us NT's don't do anything and are nothing more than the CST's backup. There are literally days, if not a week or more, we're we can't do any routines or CO maintenance, because "the CST'S are too busy" and us NT's are loaded down with CST work. Yet us NT's are expected to work late to catch everything while the "too busy CST's" are back at the office by 4pm and gone by 4:55pm. The CST's are told that if they don't want to call TAC, then call their local NT's for help, so we stayed swamped with other techs calling us and getting the whole "I got one that's not trained, can u look at the remote and see if there's an issue". I have literally been told to work a CST order, before working a TNOC outage.
I can have several dslam's down...hard, and be told to do CST work and not worry about the outages until a ticket is made and loaded to me.
At least thats how we operate in FL.
