atcomsystems.ca/forum Forums Wiring - Telecom Carriers - Trunks & Services T1's, CSU's and DSU's Fax problem caused by RX slips. (T1/Titan5500/5ESS)

From what I understand, it goes to the switch via DS3 Coax.

We also thought it might be a bad card or cable so we had the switch facility moved to a new one and there are still slips.

Ahhhh crap :scratch: LOL

5) With the router plugged in at the dmarc and mapped all the way to the switch, we get slips. If my tech at the office changes the cross connects for the T1 in the Titan and maps it over to his tberd, the errors STOP. NO ERRORS!

.... <sigh> this STILL points me to the problem being bewteen the Titian DCS and the 5E. Was the office tech changing the circuit to go to and thru his T-Berd to the switch or just ruuning off it? (not going to the switch at all during that testing? :confused:

I figured I'd chime in here. I work at the same company and have been involved with the problem. Our switch technician was remapping the circuit /TO/ the Tberd, not through it. As in, with the 5E completely out of the loop, all errors disappear. Once the 5E is brought back into the mix, the timing errors resurface.

not going to the switch at all. cross connect was changed to a test port on the titan which went to the tberd.

Have you tried moving this circuit to a different switch mod?

Are we talking about a VOIP circuit? Why the router? If we are there lies the problem.

It looks to me like an issue between the Titan and the 5E. Can you put a router in the CO on the customer NPC coming out of the Titan, with a T-BERD at the DSX-1 setup to monitor both directions?

You will not see the slips taking the circuit down and running to a TBerd, that's all there is too it, you HAVE to monitor the circuit and time the TBerd off a known good circuit to see slips. Just exactly where are you seeing the slips? 5E? DACS? Customer location? If you are seeing them at the 5E you will also see them at the DACS, assuming this goes cust, dacs to 5e. Slips are not directional, they are on both sides equally.

I am being told that we cannot see slips in the 5E and I mean as it's not an available PM in the 5E. I don't know much about the 5E so I cannot comment further. Same thing goes for the dacs. I am told that slips don't show up in the PMs on the dacs. Really helpfull, I know.

We are seeing the slips at the customer location in the integrated voice and data unit that is out there. It is NOT voice over ip. This unit acts as a miniature dacs and allows us to map x channels for voice to a 66block and x channels for data to a router card.

And Kyle, regarding your question. We did something like that. We took a duplicate of the device that is at the customer prem and set it up in our lab here. We then took the T1 at the dacs level and remapped it to the device in the lab. It showed no slips. So in this case, it goes 5E to Titan and then Titan to device in lab. No errors. I don't recall if a tberd was in the middle watching both directions for this test though but since it showed no errors we simply moved on.

Again, I can't thank everyone enough for trying to help. You guys are a great bunch.

What is the Make/Model of this unit you are talking about?
