unknown AT&T marker

[pump boy]

I ran across an AT&T marker I've never seen before.

Standard matchstick - white post with orange top but just under the match head is a light blue stripe, a dark blue stripe and then a black stripe. Any ideas?

Thanks

prob at&t transmission att/t which you prob do not locate those big trans fibers(and at&t tcg fiber) are located in house with at&t the original at&t before sbc and ameritech

I've see the ATT/T 's regularly they have an extra orange band under the match head.

the colored bands usually mean a splice in long haul fiber, the colors may be what direction each fiber goes from the splice or what size each fiber is.

At&t has those big ass transcontinental fibers that they locate in house, it might be referring to that.

Could be Level Three, fiber that is maintained by, but not owned by, AT&T, we have a lot of it in my area, but there is none of it in the next county over.
