Hi
I have a site where we are having a porblem with the incoming DNI. Some calls have it on then others come in but dont seem to have any dni. In particular we have alls with their numbers witheld but we would still like to get the DNI for that call.

Can anyone tell me if there is any special programming to be done to the OPtion 11 for DNI?

Any help would be appreciated.

regards John
 
I am assuming you are talking about Caller ID or ANI? If so you will get it on every call that contains it. In some cases ANI is not passed in the PSTN network, therefore they have nothing to send you.

HI Fletch,
Thanks for the reply. I might have misled people a bit, what I actually meant was that we seem too have a problem with the DNIS.

Our application:

Caller dials Office "A" phone number that comes into the call centre and using the DNIS we then tag the call for Company "A" and then the CLI appears. The operator then knows that the person is phoning regarding company "A".

This way they can answer the phone "Good Morning, Joe Bloggs, Supply company", but if they wring company "B" then the DNIS will trigger our system and mark it for Company "B" etc etc.

The problem is that we seem to be having a lot of calls going to Company "A" and after watching the calls coming in I noticed some funnies as I call them.

1. Some calls had DNIS of more than 4 digits (max was 10)
2. Some calls had DNIS plus it had a -1 or -1 i.e 9104-1 so dont know where the -1 or -3 has been added.

So thats the main sort of problems. Now it would have helped if the switch prodiver (Eircom in Dublin) had acutally progarmmed the thing up so that the operator could see the company name on the phone, their are two of these setup already but Eircom did not bother to do the others.

I dont know if there is a way of actually watching the ISDN30 incoming data on the OPtion 11 rather than using an Analysier, at least with the raw data we could look thru the numbers and see what DNIS is being added to them if any is being added at all. IF there is DNIS and its 4 digits then there might be something wrong in the phone system with the programming. Not sure at all how DNIS works i.e routing tables etc. I know all about DDI and how it works (have set it up in Samsung DCS switched).

So what I really need to be able to do is:

1. Monitor traffic from ISDN30 into the switch.
2. Download the DNIS routing table or any information regarding DNIS in the switch.
3. Get someone from Eircom that will actually come out and talk to me and not just shake their head............

Its all fun and games. The good thing with a problem like this is that you actually learn things from it, and I hope to learn a lot more about DNIS and option

Look forward to your reply.

No worries John, I think I can get most of your questions answered.

First off DNIS is the same as DID. From the M1 perspective, we look at them the same froma routing perspective.

You can look at the PRI message stream in LD 96 by monitoring the DCH. I highly recomend you do this during non peak hours so you do not overload the TTY interface, and when you do it, just look have it output the setup messages. Those are the ones that contain what you are looking for.

Good luck mate!

Hi Fletch,

With regards the routing, is there a table I can look at or download?

I have never monitored the PRI stream on a Option 11, is this easy enough to do? I have worked on other switches but only monitoring information from call logger and smdr outputs for taking CLI informatin.

I was looking at getting someone over with an analysier so that we could monitor the traffic but your idea seems to be better (and easier) and would not cause too much trouble to the customer.

What software and connections are required to monitor the stream?

Thanks for your help so far.

regards John
 
There is no 'table' per se. The DNIS being sent will match a DN in the system. Now that DN can be a DN on a phone, a CDN, and ACDN, or a steering code that is set to tandem out of the switch.

To turn on monitoring you need to know the DCH number. Once you have this:

LD 96

REQ ENL MSGI x <<This turns on DCH inbound msgs for DCH x
REQ DIS MSGI x <<This turns off DCH inbound msgs for DCH x

For the outbound stream:

REQ ENL MSGO x <<This turns on DCH inbound msgs for DCH x
REQ DIS MSGO x <<This turns off DCH inbound msgs for DCH x

Like I said, do this during low traffic volume, and only turn on what you need.

Hi Fletch,

Thats for the reply. Ok so it seems that what I want to do is easily done. I take it that you can save the output too some sort of .txt file?

Now how do you find the dedicated channel then?

As for ACDN, CDN etc, all the incoming calls should just go into on bit pot for ACD. At this point they dont identify the calls to any of the 4 companies whos calls are being answered. Its only when the DNIS comes up is it then flagged on our booking system that the customer is calling company "A"s phone number.


You will have to forgive my ignorance on this subject, now if you wanted too ask a question about mobile radio data systems then I might be able to answer that for you.

So by the looks of things, once I find out the DCH and also figure out how to operate the software on the pc talking to the switch then I should be fine?

Its a bit like my new job, I know have to learn about UNIX....life is just one big school.......

regards John
