Tech support and I are having difficulty getting a PRI circuit from XO using a Cisco softswitch, to work on the PRI / T1 combo card for the XTSc-IP system. We are using 8 of the circuits for the system. XO says to show the full 23 anyway. Programming done: Flash 45 NI2, ESF, FL 24 card type is 08 for full PRI, tried 02 for 8 circuits only, FL 40 TIE-DNIS.

I can't accept that I am the first person that has tried this. Even the XO tech has said that he is used to seeing Vodavi equipment installed on his circuits.

Any input would be greetly appreciated. Thanks!

I hate to say this, but you aren't going to have much luck getting it to work on a soft switch. You might be able to get them to remove name delivery from the CID and get it to function marginally. The only other option is to have them change it to a "real" PRI. There are a lot of systems out there that won't work with a PRI that is derived from a softswitch.

There's been quite a bit of discussion here about this subject. You might want to use this site's search feature at the upper right corner of this page. Look for "softswitch".

As is typically the case, Ed is right on the money. I started a post on the exact same issue several months back. Short explaination - Soft Switches send out a lot more info then a traditional switch, which the KSU doesn't know what to do with - so it dumps it into the buffer. Once the buffer fills, the KSU locks up. Reset the KSU, which clears the buffer and the problem is resolved until the buffer fills and then you're right back where you started.
One thing that has worked with some people is trading out your PRI/T1 Combo card with a PRI-B card.

Good Luck!!

Yep do a search!! Sucks!! They are both right and what a pain in the arse!!

Thanks guys. It is great to know that there are people out here supporting each other. The guys in tech support are general good with intentions, but they are bogged down by corporate protecting their back sides as oppossed to fixing issues that we struggle with in the field.

I will pick up a PRI B card from somewhere tomorrow and give this a try. One individual from XO said that a 'standard PRI circuit' can be ordered instead of the 'softswitch' version, but this is still just a comment by one XO rep.

Thanks again. Duncan

Sundance Communications, the host of this forum has the PRI-B card. Why not give them the business if you can?

SUCCESS ! !

OK guys, you may not believe this one, but I was able to get the combo card (PRI/T1) to work with the softswitch. I know that there have been techs stating that they were able to achieve intermitent functionality. I don't yet know if there are problems to be expected, or whether I have truely achieved a working relationship between the combo card and the XO softswitch PRI.

The key accorging to the XO tech in Denver seems to be proper programming of the Cisco Router. The 'CLID strip name only' command line must be entered into the Cisco Router. Once this was done, I am making phone calls successfully. Now I still don't know how a parameter for inbound calling effects the outbound calling capabilities. I am going back over to the client site to test inbound calls with and without the CLID name acceptance setting on the XTSc-IP.

I will let you know what the final verdict is. If it does not work, XO will be canceling the order for the suedo PRI on the softswitch and installing a 'true' PRI circuit.

Thanks very much for the heads-up.

Ok guys- I am new to this site, but I am turning up an STS on a softswitch PRI... our first attempt was all bad...but I believe it to be a T1 crossover cable issue...we got no sync whatsoever. I am moving the custoemr to a new location and figured that it would be a good time to attempt the softswitch PRI again- I am using a DTRU4 card..does anyone out there have any experience with this?
