Outbound Calls (RANDOM) person on the other END can hear 1

[lhiraman]

I am not sure where to start. This problem has been happening since last week, Siemens support said that the need to send out a tech to pull and pop back in the PRI card, tech showed up did that last Friday night, same issues starting Monday, the tech opened a ticket with our PRI provider, tech from telephone company said they can't find any issues..siemens tech saying it is PRI provider, IT IS A BIG CIRCLE!

Can anyone help? Or let me know how to see if any trunks are acting up.

That can be determined quickly take the two cables going to the CSU and plug them together, bypassing the CSU

This problem is killing me! It is still happening. The Telco company is telling me that everything is testing clean on their end. The CSUs are OK. The Siemens tech is saying that BLS says to upgrade to the latest software. WTF!

 

[Iamnothere]

I spent 10 years in the field. I can tell you from experience that the Telco ALWAYS says their end is good!!!

Siemens BLS typically would not request that unless your system was WAY behind the current hotfix levels. What version is your HiPath 4000? (Look in the bottom right corner after logging in to Assistant via browser.)

 

[lhiraman]

Hi-Path 4000 V5

 

[lhiraman]

Iamnothere: Believe I really do think that it is the telco having the problem. Our Siemens tech tells me that the risk of updating is no risk at all.

Upgrading is not going to fix this issue. This is Siemens standard response. This is with out doubt a Telco issue as you've changed the relevant hardware. What have the Telco changed, probably nothing. I think the issue is intermittent with the Telco equipment which could be SDH/PDH. The problem is that they can't identify the problem so blame the HiPath. Seen it all before. I've had this many times myself with network providers. Insist that they start to change hardware in order to resolve the issue or threaten to change to a new network provider if that's possible. The issue may only manifest itself during high traffic. Does the Siemens tech have access to an ISDN analyser, eg Aurora Duet?

 

[lhiraman]

I don;t know if the Siemens tech has the ISDN or Aurora Duet?

Is there something that I can test?

 

[birdseye51]

If you are the customer then this is not for you to resolve. If you are paying a maintenance contract to Siemens and you will obviously be paying for the PRI to the Telco, then the onus is on them to sort this out. I would escalate this higher more so with the Telco. The Siemens tech could test each B channel on each PRI with an ISDN tester and I would almost guarantee there would not be a problem with the HiPath hardware.
This must be very frustrating for you and an on site meeting with both parties needs to take place and an action plan put together which will involve call tracing. Lock them both in the room and do not let them out until they come up with a credible plan on how they intend to fix this or it will never get resolved.

 

[lhiraman]

Yeah It is killing me! Especially since I am not a telecom guy. I had our telephone system dropped on me only because i knew a little about punching down...killing me. Users are stopping by telling it is horrible.

 

[birdseye51]

lhiraman, can appreciate what you're saying but I think that posting on here is unfortunately not going to progress this any further. Given that you're not a telecom guy I think you've taken this as far as you can and I can only re-iterate my previous comment.
You really have to get the Telco involved 100% on this one and ask them what they've actually done in trying to resolve this rather than blame the HiPath. Again have they changed any hardware?
Just remember the HiPath has a single DIU card that supports 2 x PRI circuits, the network provider has the network interface presentation to the HiPath and all the associated equipment behind it. Just ask yourself where is the greatest fault liability.

 

[lhiraman]

Just another quick question:

Is there a way to display how call (inbound/outbound) hunt through the different PRIs?

For example:

we have 3 PRIs are call incoming and outgoing to channels 1, 2, 3, etc or are they scanning the PRIs channel 1 (pri 1), chanel 1 (pri 2), channe 1 (pri 3) and then 2 etc..

 

[birdseye51]

Having looked at the trunk configuration on a previous posting by you the trunk selection is descending so it will always try and select channel 1-2-2-23 on an outbound call. If that is busy it will try 1-2-2-22 and so on, but should channel 1-2-2-23 become free it will select that one. The incoming channel selection is controlled by the network provider.

 

[lhiraman]

So If I change it to asc outbound with go 1-2-2-1? and so on?

 

[birdseye51]

No lhiraman, if you change it to ASC all out bound traffic will always try to use channel 1 on link 1-1-1 and will only step over to the next channels of that link if busy. If you change it to CIR then it will go round all 69 channels in a cyclic mode.

 

[lhiraman]

Is it possible to down bCHAN 22 and 23 ? If so how?

 

[birdseye51]

Yes, example: DEA-DSSU:OFFTYPE=DI,TYPE=BCHAN,PEN1=1-1-1-1,BCHL=22;

This would de-ctivate channel 22 on link 1-1-1-1.

Do the same for channel 23.

 

[lhiraman]

Telco is saying that our Hi-Path 4000 is rejecting their signal.

 

[birdseye51]

If you're de-activating channels then this will be the case. If you de-activate channels 22 & 23 for example, then these have been disabled on the HiPath but they're not de-activated by Telco and will attempt to route calls over them.

 

[lhiraman]

Bird thank you for all the advice!

The Telco and Siemens tech was here today. The Telco tech replaced the smartjacks, move all the PRIs to new ports. The Siemens tech could not replicate the issue, everything seems to be working find for now. I now have a direct telco tech's telephone number.

I hope that this is the end of all of the issues. I also recieved the DVDs for the hi-path 4000 upgrade.

UPDATE:

On Tuesday (4/3/12), the Telco tech and Siemens Tech came, the telco tech replaced all of our smartjacks and moved the ports of our PRIs. We could not replicate the problem. Since then, no issues! I never realized that the telco can be such a freaking hassle.

But hopefully this is done with.
