said by battleop:Decades. I was in an AT&T tandem a few months ago and they had rows of gear in the CLEC colo area that was powered up doing nothing. According to one of the AT&T techs I know that gear has not been used since the mid 90s. I asked why it was still running and he said that no one has ever issued a ticket to remove or power down the gear so it wasn't anything he was going to worry about.
...what a waist of money AT&T prob has many like that they dont even care about the old equipment they just wright it off some where down the line and let it sit in buildings.. runing and not doing anythin a bit of good
