E1 PRI S0 on IP Office? 1

[janni78]

Is there any hardware you can connect to get a E1 PRI S0 interface on your IP Office?

Have customers that use a PRI30 as S0 on their INDeX today and would like to migrate to IP Office.

What are they using the PRI S0 for. Is it QSIG??

Fooball is not a matter of life and death-It is far more important!!!!

No it's not QSIG.

The PRI S0 acts as master and allows you another PRI interface to it.

For example I have a PRI S0 on an INDeX here in my office that I connect my testlab IP Office to.
With that I get the same functionality as it was connected to an ISDN Provider.

Hi Janni

you could use another IPO with a standard PRI 30 card setting it up as QsigA (that means master, then set up the other one as QsigB (that means slave).

Hope this helps

But I don't just want to connect another IPO to it.

I want to be able to connect any other equipment designed to be connected to the PSTN using a E1 PRI-30 interface.

The answer is no janni. It can't be done. Avaya only support BRI So8. It's not a PBX like the INDeX was.

the integral I55 of avaya (tenovis)can be connected via qsig

Whoho, someone understands me

I know the IPO hasn't this, but some kind soul in the world should have built a 3rd party hardware that can solve this and be connected to the IPO in some way.

All So8 means is making a BRI circuit into a 'Network' point as opposed to a 'User' point. When a BRI is the 'User', the telco exchange is the 'Network' and when it's a 'Network' then the VidConf (or whatever) device is the 'User'.

You can alter it's state by using QSIG - one has to be the 'Network' and one the 'User'. However, Avaya do not clarify whether QSIG-A or QSIG-B is what. 'Network' and 'User' terminology is standard talk in ISDN speak and they had no idea what I was talking about when I rang them. In IPO QSIG networking, all they know is one has to be 'A' and one has to be 'B'.

You could try this but I won't promise anything. There's also a setting in the Line config for a PRI to set as either CPE or CO. It says it's only for Brazil/Argentina user (or it used to) so this might be worth a go too.

Humm, guess I need to take more time in my testlab

Now I also have people who would like to connect equipment through DPNSS to the IPO. Guess that is totally out of the question.

You can get DPNSS/ETSI converters which in theory should work. Whether you get Avaya to support you if you have problems or not is another thing!

 

[janni78]

Humm, do you know where I could find a DPNSS/ETSI converter?

I gave up the thought about Avaya or my distributor supporting me on this a while ago

 

[disturbedone]

This is a DPNSS/QSIG converter made by Westell in the UK. I remember seeing a Tech Tip or Job Aid years ago about Westell. Not sure what it was about but might be worth digging out.

I found them while goggling and it seems like it will do the trick. It will even convert to a h.323 line which is even better.
See if I can get one for testing if the price is right.
