atcomsystems.ca/forum Forums General General Telephone & Systems Information Can a Voice T1 run without power but on Generator instead?

CO A has its own outside plant facilities. So does CO B. It is extremely rare, at least in my area (SBC land), for wiring from two different rate centers to touch the same customer premise. I'm not saying it's impossible, but I have only seen a couple of isolated cases in residential areas. And this rare case was caused by the buildout of a new central office.

The telco most likely hauled the circuit from CO B to CO A via optical carrier or DS-3, then both ride CO A's outside plant to your facility.

In either case, if I take out the pole outside the building, you're still down. If the tech doesn't properly close the splice case in the manhole outside and it floods, you're still down. If Billy Backhoe is excavating and turns that 200 count buried cable into a 150 count aerial cable, odds are pretty good that you're down. Don't ask how I know about the last two...

You have to deal with possibility and probability. You can't cover all the possibilities without investing a ton of time and money. If you're only dealing with probability, well, it's still a lot of time and money, but a few less grey hairs.

How do I know if there is a "repeaters" on the T1 line? I believe there is a distance of 2.8 miles from the CO to the office.

So if I understand correctly.

1. Repeaters are powered by the power company(not the T1 line). When power goes out, they go down even if the CO & customer office are powered by backup generator?

2. Damage to the Pole outside the building will cause a T1 to go down no matter how many T1 you have from different companies.

Even if these condition are met.

A. Everything in the phone closet connected to a UPS being recharged by generators
B. CO up and running (maybe on generators also)
B. CO Network intact.

You will still be down if either 1 or 2 are true?

Please let me know.

Thanks.

A good many customers are now fed though SLC's (Subsciber Loop Carrier) or Remote Terminals. These are powered by commercial power but also have battery backup. The problem is with the condition of some of these batteries. They could last from 4 hours to 2 days depending on the amount of usage. Some CLEC's in anticipation of power outages from storms, provide backup generators at these RT's. Hope this helps.

Correction LEC's. Most CLEC's don't have facilities

Thanks, that is some good information.
