router's clock for PBX

[mljevakovic]

URGENT!

I have a router 2801 who has E1 controller. Through this controller I connect router to PBX (Avaya Tenovis Integral 33. Because the PBX cannot give the router sync clock how can I setup the router to give sync clock the PBX.

"clock source internal" unde controller E1.

Also do not forget the commands networks-clock-participate and network-clock-select.

Hope this helps, please rate post if it does!

I've tried but I've got the message: "Controller e1 0/0/0 is not deriving clock from line."

[paolo bevilacqua]

Right, this is the case when controller has clock internal. So leave the "networck-clock" commands as default and you will be sourcing clock to the PBX.

[mljevakovic]

I cannot see the command "network-clock-select 1 E1 0/0/0" in my sh run output and I've still have "slip errors".

[paolo bevilacqua]

That makes me think the PBX is indeed using internal clock.

Try setting clock external and "networck-clock" commands on the router and see how it goes.

[mljevakovic]

I've put clock source line and after that I could put the command network-source-select 1 e1 0/0/0 and also now Ican see it in th sh run output.

[paolo bevilacqua]

Now check for slips and if possible do the same on PBX. The try sending a long fax between router and PBX and if it goes you're all set.

[mljevakovic]

sh network-clok get me

Priority 1

Clock source E1 0/0/0

Clock state GOOD

Clock Type E1

there are no slip errors but it seems that PBX cannot get sync clock from router. :(

Is there any way to check more...

[paolo bevilacqua]

What is the PBX reporting ? When the router is set for internal clock but slips are seen it means the PBX is not resend back router's clock but it's own.

[mljevakovic]

here are my cfg file. Is there anything wrong?

[paolo bevilacqua]

Nothing wrong but nothing is configured under controller E1.

[mljevakovic]

This is config of controller e1Č

framing is CRC4

Line code HDB3

Clock source is line

[paolo bevilacqua]

That is all good but unless you configure pri-group under controller there is no way you can connect voice to the PBX.

[mljevakovic]

How can I do it?

I've put isdn switch-type primary-net5 in global config mode and after that I tried to config pri-group under controller but I ve got message "Insufficient resources to create pri-group -it has been removed"
