ISDN BRI on IP500 "PHDI" issues 1

[technicaluser4]

I have an IP500 with BRI 8 Card and 4 BRI lines connected.
I am set up was point to point configutation with my provider and got 1 line set to (network clock) another as (fallback) and the other 2 set to (unsuitable)

Calls are dropping off during conversations and I noticed the following in montior:

Have noticed also the follwing error in System status:
Alarms in the Service Section:
Occurences: 40
Error Description: 8Khz clock source changed, Previous source was Line6: Slot: 2 Port: 2


My IPO was running (4.0)after that I read that there were some issues with ISDN lines going out of service I have upgraded to 4.1.12, but the problem persists.

My hardware conists of:
IP500
Slot1 = 8port analog analog extension+4-port analog trunk card
Slot2= 8-port digital extension+8BRI trunk card
Slot3= VCM32 extension card
Expansion 1=Digital Exp DS30.

Anyone met this?

 

[mattKnight]

Usually, we set all BRI lines to clock from the network. This has caused us no problems.

Take Care

Matt
If at first you don't succeed, skydiving is not for you.

 

[VoiceonData]

Yep ive got the same issue.

with systems set the same as Matt

and now trying just one BRI set to clock


Thought i was going mad

 

[tlpeter]

Always set ONE for sync (clock) and ONE for fallback !!!

Here some info about isdn

Value Message
F1 Inactive
F2 Sensing
F3 Deactivated
F4 awaiting signal
F5 identifying input
F6 synchronized
F7 activated
F8 lost framing


ISDNL1Evt: v=[line_no.] peb=[hardware device no.], [message]

Where BRI L1 sates value is as follows :-

Message Description

PHAI Physical Activate Indication (i.e. Line is UP)
PHDI Physical Deactivate Indication (Line is DOWN)
T3TO T3 timeout has occurred
TxErr A Transmit error has occurred
UnLocked The IP Office is not able to lock its clock to this line.
Locked The IP Office and the clock extracted from this line are locked together.

tlpeter

Thanks for that useful info

have a star

 

[TomMills]

Oh Dear,

i have just put a BRI card in about an hour ago and realised i may be popping back into site tomorrow to change the clocking.

Schoolboy error

>>i have just put a BRI card in about an hour ago and realised i may be popping back into site tomorrow to change the clocking.

Can you not dial in via ISDN modem?

Tom

Is your Mum cooking dinner again Its about time you found the cooker.

He He

 

[TomMills]

i am cooking all by myself, honest.

i am actually very proud of my culinary skills, and wireless means i can surf the web from next to the hob

Hi, had a similar issue once.
Turned out that the service provider was running maintenace tests during the night. That was IPO sw 3.0 or 3.1, the IPO freaked out, had to reboot it to get it work.
Monitor traces looked similar then.

 

[technicaluser4]

This is what I have here...I mean
Line 5 - network clocking
Line 6 - fallback
Line 7 - unsuitable
Line 8 - unsuitable

Calls keep dropping out. Therefore the conclusion is that it seems that I am prefectly set up and the calls are dropping due to provider problems although they are not catching them!

What do you think?

 

[Bas1234]

Did you try to put them all on networking?
I normaly put them on networking and had no problems, only Mobile Gateway's and other ISDN hardware who do not provide a clock.


Greetzzz...Bas

If you can get the service provider to run a trace that they can look back to when it happens it would be good.
The must see something, even if it's the IPO that's causing this they should see it

 

[technicaluser4]

Thanks guys! even if we went through all the subjects such as sexy receptionists, mummies, cooking. I think there is some truth in all this!

 

[technicaluser4]

The only way I got the system working without errors until now is to disable all clocking from all lines (suppose that IP Office is using its internal clock).

I just want to hear whether someone here that have an IP500 and a BRI8 card inside (runnning 4.1.12) without any dropped calls problems.
If yes, please, how are you set
up? point to point or point to multipoint? and then what clock source are you using.

I am getting clock changed alarm in system status all the time when i put one line as network and another one as fallback.

 

[tlpeter]

That alarm must be in black with 8kh has changed

This is normal because you did a reboot after the change
You need synchronisation so disabling all will give problems

hi tlpeter,
I can see the alarm in the system status and it does not appear only following a reboot. I can see it increasing with time. Clock switching is happening all the time.

Everytime the alarm comes in system status I notice a PHDI event in monitor and another user complaining that his call just dropped.

I changed the circuits to point to multipoint with provider but the problem did not disappear.

I have also noticed this error in monitor:

[tlpeter]

Oke that is a different alarm
This is monitor and it remembers 20 alarms

But when your alarm keeps increasing there is still a problem !

I will explane your trace a bit

760756mS ISDNL1Evt: v=7 peb=7,F3 F7
760756mS PRN: T4 Started
760951mS ISDNL1Evt: v=5 peb=5,F3 F7
760951mS PRN: T4 Started
760961mS ISDNL1Evt: v=5 peb=5,UnLocked
760961mS ISDNL1Evt: v=6 peb=6,Locked
760961mS PRN: BRI: LockToPeb 5

peb=7 means the isdn line 7
F3 F7 means Activated(F7) and then deactivated (F3)
This is always the last one first and then the first one
T4 started means that it is trying to get synchronised again
peb=5 unlocked meand it is locked to the clock anymore
peb=6 locked means the clock is locked
This will give a reboot because you can not be called anymore and you can not make external calls anymore

You realy have a problem with the line(s)

What you need to do is go in to monitor
Go to filter -> trace options -> isdn
Press clear all and select all the isdn settings except for the "trunk packets(ip401 only)"

Let that race run and show it when it goes wrong again
