You can get Adtran ACE CSU, non-display. Two on ebay going for $15 each right now. About a day left.

OK this may sound like a dumb question. Is there a standard log in for Smart Jacks like the Adtran H2TUR. I know you can use Procom but what settings do you have to change in order to login.
One of our local land line companies is telling me it is nnot possible to change the LBO on these cards and my equipment is not going to come into service until it is increased.
Thanks

The H2TU-R (HDSL 2-wire remote card) is Network terminating equipment. This card ends the regulated piece of the local circuit. It’s NOT a DSU/CSU and belongs to the Telco and should not be accessed by a non-regulated company’s technician…. That unit would be THE DEMARC in most cases. The LEC person you spoke with must have been mis-informed (that’s a nice way for me to put it.) I suggest pushing back on them to change you LBO settings on the unit. The default setting is 0-133 ft. It can be set up to as far as 533-655 ft. Again I’ll state, “THIS IS NOT A PIECE OF EQUIPMENT YOU SHOULD BE INTERFACING WITH!†… That being said, if I were in your position I’d change it myself too!  :shhh: Here’s a link to Adtran’s I&M pratice on the HDSL2 remote unit: https://www.adtran.com/adtranpx/Doc/0/F5OGTS8PGEJ494J150A9PH2T2A/61223226L2-5A.pdf

Adtran NIU's are typically 9600, 8N1. You could place a CSU between the smartjack and your equipment, and set the LBO on the CSU to cover the distance.

Sorry to hi-jack this thread, but, I have tried to connect this CSU to Time Warners PRI interface & it does'nt work. If I plug it directly into the SBC smart jack, it works.
It must be a pin-out issue, but I have'nt had time to play with it.

How is Time Warner delivering their PRI? You might need to use a T1 crossover cable. T1 uses pins 1,2,4 & 5.

I am in agreement with Kyle. Ours here required a crossover cable. While it's true that you can get by without a CSU, we have had instances with video over PRI that failed miserably without the CSU being there. Maybe voice traffic is more tolerant than video?

I tried a cross-over cable...no dice...
We actually have this at our office. I still need to find the time to play with this, but, when I came across this at a customer site, I got a replacement and tried it at our office. Pins 1,2,4,5 straight from Time Warners channel bank to my NEC IPKI. When I put this CSU in between, no connection indication, when I plug it into the SBC smart-jack, I get connection indication...weird...

Every Time Warner Versa pack bank we have worked with required a flip of the pairs between the bank and customer premise equipment. No CSU in line.
