Help needed for BCM400 with 3 PRI 1

[gleduc]

Hi
I have a problem with a bcm 400 4.0 (patch up to date) with 3 PRI.
The problem we have is we are unable to have the 3 PRI working. (Only 2 works)
The one who don't work is never on the same circuit and/or on the same bus.

Here is our config:
Bus 6: PRI, DMS100, clock: primary external
Bus 5: PRI, DMS100, clock: Internal
Bus 2: PRI, DMS100, clock: secondary external
The bcm have 4 PEC card and is in 3/5 DS30 split.

We tried:
1: remove DTM card from bus 2=> bus 5 and 6 works
2: remove DTM card from bus 5=> bus 2 and 6 works
3: remove DTM card from bus 6=> bus 2 and 5 works
4: switch circuit on DTM card=> the problem stay on the DTM card.

The provider told us that all 3 d-channel are up and sometime the system rejects the call.

Anyone have an idea?
Thanks

Have u tried changing the DTM

 

[gleduc]

No because the problem is never on the same DTM card

Why are you using DMS 100?

 

[gleduc]

These PRI providers always offer only this protocol. Why? other are better?

Are all of the trunks in the same pool group/Bloc?

What symptom do you see on the BCM side to indicate the PRI is not working?

At the beginning, all the trunks are in blocA.
For test,
I put each PRI in a pool different (BlocA, BlocB and BlocC)
I had created a routing table (91 for blocA, 92 for blocB and 93 for BlocC).
If I dial 91, 92 or 93, I can get the PRI I wants. (execpt the one not working)

The problem is only 2 work in the same time, never the same bloc. If I disconnect a working one (ex blocB), the other one will work (ex blocC). If I reconnect it (blocB), it will not work and blocC will continu working.

At this point, I don't know what to verifie...

Thanks for your help.

Have you verified with Telco that each PRI has its own unique D channel?
It has to be 1 for 1. Each PRI must have its own D channel.

What is the symptom on the BCM side?
For instance, if you have all 3 PRI installed and try to make a call ... do you get "no free lines"?

Any errors in the alarm log?

I hate to leave you hanging on this one but I had to respond to a customer a while back where they had 3 PRIs and their 400 never processed any traffic on 2 of them, ever.I There are configuration limits on the number of B channels you can use outgoing and by default it is set to 23. Problem is, right now I can't remember where it is in the 400. Unfortunately I'm sitting in front of a 450 at the moment and it doesn't look like that option is in here.

Something tells me its in the Telephony Metrics>CBC Limit Metrics under the Admin tab but I'm not sure. In my case, I changed mine from 23 to 69 and the system started processing them all properly ie. Ascending Sequential from the highest number outbound.

I'll check tomorrow on a 400 system. If I'm in front of one, I'll find it in no time.

Sorry.....old age, short memory.

Do it through telephony programming.. It's under System Programming.. And you're right.. I looked on a 4.0 system and couldn't find it..

Hi all, thanks for your respond.

SupportDube; the provider confirm me that we have 3 d-channel and all three are up. At the bcm side, no alarm, and if the 2 PRI are full (46 lines busy) for outgoing call, the systeme give me: <congestion system>, for incoming call, we get a fast busy.

Telcodog; I will verified this today, but what I see at this moment in this section, it's only for information.

Like I said earlier, I'm not sure that's the right section to look at. I will respond as soon as I get in front of a 400.

Hi all
My problem is resolve, with the answer of telcodog, I found in Configuration/Telephony/Dialing Plan/Line Pools and select my PRI bloc, in Call by Call Limits we can enter maximun outgoing and incoming call. So I put 69.

Thanks all for your help
telcodog, I give you a star!

Now you know why I had a hard tme remembering where it was.
hahaha. Took me a while to figure it out the first time too.

Glad you got your issue resolved though.
