Direct Outward Dialling on Hipath 4000

You will need to be much more specific than that! Which board do you want to add?

DIUT2 board.
I am currently using it for DID, but how can we program it to use it for DOD?

Probably standard routing?

ADD-BUEND;

ADD-TDCSU;
ADD-LODR;
ADD-LDAT;
ADD-LDPLN;

The same way you dial out on any circuit on the 4K

Don't forget RICHT!

ADD-BUEND;
ADD-COT;
ADD-COP;
DIS-LWPAR; (the User/Network selection)
DIS-COSSU (Trunks require COS and LCOSV & LCOSD for tandem scenarios such as linear topology)
ADD-TDCSU;
ADD-LODR;
ADD-WABE; (dial codes e.g DAR = TIE if these are truly external/CO trunks)
ADD-RICHT;
ADD-LDAT;
ADD-LDPLN;

If your existing circuit is ISDN PRI, and it is currently functioning as incoming DID-only, you probably also need to contact your Telco, as the OUTGOING capability for those trunks may not be enabled. It would be sad for you to perform all that AMO work, then experience failure because the trunk circuit is not immediately capable of supporting outgoing calls! This may result in additional monthly expense to the Telco!!

WARNING: If you are not experienced with the configuration of Least Cost Routing (LCR), be extremely careful - especially when DELETING (attempting to "un-do" something that you perhaps misconfigured). You can easily delete all of WABE and all of LDPLN if you are inexperienced! My recommendation: contact your next level of support for this work!!!!!
If you want to pursue the configuration yourself, I encourage you to find similar trunks and similar LCR config, and use the REGEN verb to see how similar LCR and trunking scenarios are configured.

Yes of course RICHT
you can also use LPROF depending on your setup.
I would say that outbound routing is one of the major items in hipath so iamnothere says above you should find a working situation and copy it.

Thanks all for reply.
But I also need to ask, if the ISDN circuit is a 30 channels circuit, can I have the capability to divide the 30 channels (for example with a ration of 20 channels : 10 channels) between DID and DOD?

You can segment the trunk
make 2 bcgr groups in the tdcsu
so you would
add-tdcsu with 1&&19 for bcgr 1
then add-tdcsu (extend) with 20&&30 for bcgr 2

set bcgr 2 for your outbund in your routing

Aha
but how can I set the bcgr 2 for outband?

and also should then I make 2 TGRPs, one for the incoming and another for the outgoing?

Yes you need 2 or more trunk groups so as you can set them up in the routing.
You technically do not need a trunk group for incoming but you could set it up
and assign a test code to it to see if its up and running.

OK.
sorry for the disturbance, but I still need to know two more questions:

1. Can I program 2 access codes (with 2 buend, 2 richt, 2 ldpln) over 1 30-channels PRI circuit (programed as DID/DOD) (the same TDCSU)? or I have to program just one access code?

2. Can I program one access code over two cricuits, one is DOD (PRI) and another one is COT(analoge)? (The same LDPLN over TACSU and TDCSU)?

Thanks a lot.

OK, I have to be stupid and ask this question because it's been bugging me.

I am quite comfortable with DID - I use it all the time, but what IS DOD?? Is there some realm in the world where phones are not allowed to call out by just dialing 9 or 8 or some other access code in the normal fashion? Why is there some special category for this? I pick up the phone, dial 9, and it's routed out the nearest PRI channel or trunk. That's about as direct as I get... Or is this more like DTS (Direct Trunk Select) where you can actually select the specific trunk channel you want to dial out on?? Sorry to be stupid, but it's confusing me because if there is some kind of dialing restriction wouldn't that be done with COS?? I was under the impression that DID trunks were unidirectional, so I doubt it has anything to do with that... I understand all the conversation that is going back and forth here about partitioning the PRI spans. I just let mine run free and the balance is usually fine, but I could see some circumstances where a company has so much incoming volume that they want to set aside some of the channels for outgoing only, and that's easy enough to do with trunk groups and routing, so I would think that's common....

So I'm open to learning something today if someone wants to explain what it's supposed to do.

Hi donb01
I agree - I have only set it up once and that was for a company that required only 1 channel to be kept spare for testing outbound. I would assume that the carrier did not know about this and sent calls in on that channel anyway but the customer was happy with his access codes and single channel -they can test all their circuits every morning.

@SaeedAyman

1. Can I program 2 access codes (with 2 buend, 2 richt, 2 ldpln) over 1 30-channels PRI circuit (programed as DID/DOD) (the same TDCSU)? or I have to program just one access code?

Yes you can setup as many access codes as you like going out on whatever circuits you like.

2. Can I program one access code over two cricuits, one is DOD (PRI) and another one is COT(analoge)? (The same LDPLN over TACSU and TDCSU)?
Yes you can do this as well - in the LDAT you will specify your PRI first and your TACSU analogue second choice (or the other way around if you prefer)

Thanks all for your helping.

But I still need to ask a question
how can I set the second bcgr (which contains the DOD channels in the circuit) for outbound in the routing?
Is it just by configuring the rest of the commands, (richt, ldat, ldpln,etc.), or there is another step to adjust the bcgr2?

Again thanks a lot.

Another question,

I have noticed that after dividing the 30 channels (into 20 channels for DID and 10 channels for DOD) that the outgoing channels are seizing the dedicated 10 channels, but for the 20 DID channels, they seize any of 30 channels, including the DOD channels.

Is that normal? or I can do something to limit the seizing of the DID channels?

I assume that the FIRST 20 channels are for incoming
and the LAST are for your outgoing

In your TDCSU for the Incoming channels change the circuit as follows:
CHANGE-TDCSUEN=X-X-X-X,BCGR=1,SRCHMODE=ASC;

For the Outbound last 10
CHANGE-TDCSUEN=X-X-X-X,BCGR=2,SRCHMODE=DSC;

In that way incoming calls will always try channel 1 first and then 2 and so on.

Out bound calls will always try channel 30 first and then 29 and so on.

If they 'meet in the middle' you have a decision to make,
Do you have enough channels for the site?
Would another circuit be advisable?

You could stop incoming calls alltogether on the 2nd BCGR but have you considered what your customers would think if they get a busy signal?

Yes, I already have another circuit for the incoming, so how can I stop the incoming calls for the second bcgr?

Don't you have to tell the provider how you want the incoming calls distributed on the channels? Normally it is either a hunt up or hunt down type of configuration and it doesn't matter what you do in the switch, if a 21st call comes in it will hunt to the 21st channel - it may get a busy signal if you have it blocked in the switch, but the provider will still send it there, unless you direct them to allocate the channels used for incoming calls. ??

Aha, so I tell the service provider how do I want to distribute the channels, because I have only told him that the circuit will provide incoming and outgoing, and I thought that it is an issue for me to distribute them
