Just curious, but what voltage should I get out of the Smartjack? Trying to debug a mysterious PRI that always "tests clean to the NIU".

Out I don't know as I've ever seen this. On the CO side there is a simplex current to power the repeaters. I've never heard of voltage on the drop side. I can tell you the level you should have and frequency, but that's about it. If it test clean to the NIU does it test clean to the CSU? Maybe one of the CO guy has your answer.

I'm trying to get the CO guy to call me so I can loop it up for him. Asterisk doesn't automatically loop the CSU when the CO issues a pattern test.

We used to get request all the time James to run to customer loop. So unless this is a working circuit I'd just loop it up and request they run to your loop. Most CSU's I've seen, even those built into a T-1 card have the option to loop up on the pattern commands, I said most I know there are those that don't, but you might want to see if the option is available to you. I know you know that stuff in an out, but it's possible.
Do you have capabilities of getting the T-1 status and error report?

Working on getting it out of them. This is a working circuit.

James is this a local T-1 or does it run over legacy AT&T network?
Are you able to Pull PM data out of your CSU?
Has whoever is testing your T-1 pulled the PM data from the NIU if equipped?
The AT&T switches used to store PM history.
So there should be several sources to non-intrusively pull error information.
Finally just what is the trouble?

Need to clarify something I stated about simplex current. I've been around awhile and I really don't believe there are line powered repeaters anymore. There used to be an extra charge to power the NIU via line current. I'm sure one of our CO types can verify this.

Originally posted by justbill: Finally just what is the trouble? That's my big question too... I think I should be able to find a voltage spec out of the NCTE (Network Channel Terminating Equipment; aka smart-jack) for ya if’in it would really help ya out at all. … In order to do that, I would need to have an idear on what kind it is though. Manufacture, model, type, part number, etc…

Nearly always the NCTE is line powered now days… I’m not a billing person what so ever so I’m not 100% positive on this but I’m pretty sure there’s only an additional charge if line power is REQUESTED.

Thanks Bryan. Never know in this day and age. I've been away from the hands on for awhile now.
