D-channel link connection failure 1

[basboers]

In my 2000IPS v12.2 i get the message; 21: DCH/BRT/PRT D-channel link connection failure.
The alarm is comming from the 4BRTA from 5 remote sites.
I have no problem calling or what so ever.
Can somebody explain what this is?

thnx.

The dchannel reset.

Remote sites? Are your refering to Remote PIM over IP?

The problem is caused bij the remote PIM's, we've already tried to do a reset on the Remote PIM's but that had no effect. Every time we clear the alarms they come back.

Bij your message and screen name I would assume your Dutch. I was just wondering if this is applied in the US or in the Netherlands. There are a few switch setting that need to be changed for proper operation/clocking if they are being used in the European market.

Dank u

Good guessing....i'm Dutch.
On the 4BRTA we've put sw1 to ON.

 

[DrVuDu]

so you are not using the DAID/DAIE cards for a T-1 (E-1) remote PIM at all.

is this a CCIS network?
Remote PIM over IP?
Point to Point (TIE) BRTS?

Star or Ring Voice Network?

Please Explain how a call from one site goes to the other, each has a different approach for us to be looking at.

We have 1 Main site with a 2000IPS and connected with 8IPLA's to 6 remote PIM's they al connected to a VPN network.
Every site has his own 4BRTA card where the in/outgiong calls are made. We have onw the remote sites only IP dect.
The ISDN lines are P-P and P-MP but most of them have only P-P.

ahhhh IP DECT wireless. I'm going to look up my contacts for the EU and see if I still have a buddys number in Hilversum that should be able to help you out. I do remember that philips was having problems at a BOSCH site in NL with DECT.

There are already poeple from Hilversum troubleshooting on our site.

 

[DrVuDu]

BasBoers,

if you have the Hilversum boys on this they have the ability to directly contact NEC Japan and other NEC Worldwide resources for this issue. I have sent them some information that may be useful, but I can not release it on the public boards. I do hope it helps!

goed geluk

I think that might be normal, I remember one time in the past I had similiar alarms with IP CCIS and ran it by NEC and they explained to me that IP CCIS is sort of like Event Based CCIS in that the link looks like it goes down when it is not needed and then comes back up when needed. I am going back a few years but this is what I remember!.

 

[basboers]

OK, thanks for all your help.
But i think Philips has sorted it out.
It has to do with our ISDN provider who uses diferent PABX's called a 5ESS and the EXA, what happends is that after a call our D-Channel goes down for half a second whan our lins comes from a 5ESS PABX from KPN.

cheers.
