Could I please know the steps to program a DOD card on hipath 4000?

Thanks a lot.
 
If you only want incoming calls on the lower 20 channels you need to tell them that. Otherwise the whole span is opened up for bi-directional use. Normally the way these things work is your incoming calls ring in from the top down, and your switch is programmed for the outgoing calls to go out from the bottom up. If you have enough capacity you rarely crash in the middle. In this manner your span is very dynamic and you could theoretically have 30 incoming calls or 30 outgoing calls, or any combination of the two. What it sounds like you are trying to do is similar to how VOIP works - in that case you want to give phones (say incoming calls) priority on the span, but you want to set a limit so that you never get so many incoming calls that you can't dial out.

Your provider needs to be in the loop on that so they enforce the same limits that you do.
 
It can also depend on the carrier, some allow b channel negotiation.
They may not be able to segment up a circuit and you might be better off with incoming on one circuit and outgoing first choice on another.
If it was me I would ask the carrier to send the calls in on alternate circuits to give you resilience.
You will always have busy times at least twice a day.
You could do traffic analysis in the assistant to see that.
 
On my main site I have 3 of them in a hunt group from the provider. Calls come in from the bottom up, and I have my switch set to dial out from the top down. That allows the full dynamic of the 3 trunks and if it's going to crash in the middle there would have to be over 60 external calls coming or going at once. Management signed off on my 3 year fight to bring the whole organization up to the 4000 and I'm going to be adding an E911 system in there as well - it is inevitable the legislation is coming so I might as well be proactive. We decided for that we are going to pull out the middle 4 or 5 channels into a separate dedicated trunk group for the E911. I don't think either the users or the E911 system will never run out of resources.
