my switch resides in the 203 area code. when I 'li ars anal' and see the entry for 1203 it goes to rp 9 which has 3 trunk group choices with NPA's of 200. What is that all about. Everything else in the table has the 203 but the main 1203 with min 11 and max 11's rp has 200. What would be the justification of it being that way?

martinyoung

It will depend on what type of circuits these are. NPA of 200 is a flag for certain kinds of circuits and if you change your route pattern you will probably break it.

What are the entries in the bottom half of the screen?

If it concerns you, you can probably change the NPA field to blank. That generally has the same result.

what do you mean break it.. if i enter in another rp # it will cause me problems??

btrain2871

at the bottom.. there's nothing entered in anywhere..

yyyyynn n rest none for all at the bottom

martinyoung

Yes, all calls to that route pattern will be blocked (in your case that is route pattern 9). Some ISDN T1s do not respond well if you enter the home NPA of that circuit in the route pattern. They prefer a blank NPA field or an NPA of 200. If you want to test this, come in after hours when no one is there and change route pattern 9 to reflect your home NPA. Then make some test calls that would use that route pattern and see if you can still get out.

I, personally though, subscribe to the theory that if it ain't broke, don't fix it.

so what about if i create other entries of 'fuller' #'s.. instead of 1203 what if I create another entry of 1203434 to make the calls go off? the issue is my T1 span that is the 1st entry in that 200 route table is the T1 that's coming down and I want to make sure the calls go out if I make changes.

martinyoung

Yes you can do that. Create a duplicate of route pattern 9 and direct one or two specific numbers to it in ARS. This will allow you to test to your heart's content. Bring up a list trace while testing and you can see how the call goes out.

but what if I don't use rp 9 in my test and enter the individual #'s callers are trying and use another rp for the calls to go out while the span is down

martinyoung

You say that route pattern 9 has three trunk groups in it. If one of those trunk groups fails, it will be failed in all route patterns that send calls to it. What your PBX will do is send calls to one of the other members of that route pattern automatically if one trunk group fails without you doing anything unless you have escalating FRLs in the other choices.

If I am not understanding your problem, then please explain what you are trying to do and why.

Another thing you can do is change the order in the route pattern. Your PBX will always choose the first trunk group in the list first (unless there is an FRL conflict) until all channels are in use, then it will choose the second group in the list.

I have my carrier coming in because they want to migrate this 1 PRI that's on old technology (smartjacks). They are going to swap out the smartjack in my comms room and the other end which I guess is in the basement. during this time that span will obvsiously be down and it happens to be the lead trunk group in most of my local routing patterns. My incoming did's should still flow as i have another pri linked with this 1 but it's the outgoing calls that I want to be seamless. I'd rather change that ars entry from rp 9 to something else with another lead circuit but if you're saying the 2nd member in rp 9 will take the call if the 1st is down then I guess I'd be fine. I'm just trying to avoid having to do anything on the pbx end if necessary as they say this work may take no more than 20-30 mins

martinyoung

For a short time the PBX will be unaware that this T1 is down so some calls might have a problem. The easiest way to make sure nothing happens is make one of the other trunk groups in each route pattern first choice. This is not service affecting to do and if you do it long enough in advance there will be no outgoing traffic on the pipe. The only calls affected will be any incoming calls.

even changing the order of trunk groups on that rp 9 with the 200 npa?

martinyoung

Keep all the info for each trunk group the same as it is now on each line. Just change the order on the list. This will have no impact on calls now up. Once you press enter outgoing calls will follow the new order and the outgoing calls on the T1 you are interested in will dwindle to zero, this is what you want so that there is no cut off on existing outgoing calls when the vendor work begins.
