Rural Century Telephone remote terminal unit
Rusty old Century Telephone / CenturyTel RTU?
It doesn't say CenturyTel. Just RUBY in red letters
Gray splice box by road has same RUBY in red letters
I have heard that this is our local remote terminal unit for CenturyTel. I'm way out in the boonies about ten miles from the CO, but I'm told DSL could be run from this box to us about 2.1 miles away. There's a long string of the silver can 621 App Cases up to this box.
It doesn't explicitly say CenturyTel, at least from this view, but it has RUBY in red letters, which is also on the large gray metal telco splice box by the road. What with the rust on the bottom, this RTU is probably 20 years old or more and likely is from when the CenturyTel megacorp was still just Century Telephone. Anyone ever seen one like this?
Since it's out in someone's field, these photos are taken from the road. I don't want to be trespassing to take photos of it, but I'd like to see the other side. Does CenturyTel own the driveway up to it, or can RTU's be installed on other people's private property?
I have no idea how the phone company determines where to put these remote terminals, but Ruby WI was once a large logging camp in the early 1900s which then folded up and blew away, and there is still a large run-down old building by this box that was once a country store.
It seems possible that there might have been a rural telephone exchange at this location back in the logging camp days. The first RTU out here may have been plunked down back in the 1950's - 1960's to replace the local office and take over the trunks.
Hmm, is this it? Wandering around this site there's a thread about RTU's and a PDF with images of them. While I can't see the front access door of our RTU, the vent grille of the base and the general shape looks very similar to this one from the battery retrofit catalog.
AFC RFC-120 / AFC-120
Apparantly a pile of 48v batteries sits in a drawer in the base of the remote terminal. Neat!

RTU Images PDF (battery retrofit guide), look at page 12:
I've been googling around for AFC but I cannot figure out what the initials mean.
Here's a company making a retrofit kit for the AFC-120 to go from 300 watt to 800 watt equipment capacity. Hmm, so the little edge-over top cap is actually a fan shroud, apparantly sucking air up through the internal hardware rack and out the top.
As they say:
For many years AFC stood as one of the premier access providers to the hundreds of US based Independent Operating Companies. Literally thousands of small line count AFC cabinets are deployed in networks across the nation. Originally deployed for POTS only, some cabinets were upgraded to support DSL on a percentage of lines, often bringing the cabinets to their thermal and power limits.
With the introduction of fiber transport, high-speed data and video services, and ever increasing takes rates, carriers turned to the next generation of access equipment. But while the original electronics may be superseded, most of the installed AFC cabinets have many years of serviceable life left in them. With a well engineered set of changes, these cabinets can easily be adapted to support many of today's newer systems.
AFC was bought by Telabs a few years back..;)

2004: Tellabs to acquire AFC for $1.9 billion in cash and stock
And of course you can't really expect them to stop making what has been such a great seller under the AFC brand name. Tellabs still makes two models with this shape:

Based on the short-squat
appearance of our RTU, we probably have the 120-line model.
Thanks for the help with this useless but interestingly inquisitive research project.

Probably contains a single channel bank fed by metallic DS1's aka T1's.
If you cannot fix it with a buttset and some bennies you ain't a technician.
I know it's not, but it looks VERY close to the MESA Sport cabinet. That cabinet has 3 copper DISC*S shelves (300 lines), a Charles Industries Wescom T1 repeater and a Alcatel-Lucent DDM-2000 OC3. Like I said tho, VERY CLOSE!
The box at the very bottom should house batteries. With a base that large any combination of 12/28's or 12/155's could be under.
