Slips on PRI, smeared faxes

[VoIPgirl]

I believe that I am having slips on my PRI that is causing some faxes to look smeared. I am looking at the list measurements DS1 summary. Should errored seconds equal controlled slip seconds? It doesn't seem to be on all...
Thanks for your help.

if the span is clean it should all say zeros

I have no technical solution to your management problem

Do 'status syn', it should be on a ds1 board, not on the tone board.

It says on TONE-BD. How do I change this? It doesn't seem to be on all faxes. I am wondering if the actual PRI's have slips on them and not from the synchronization issue.

 

[orypecos]

do 'display syn' and see if that has ds1 boards for your syn plan at the top. If it does, do 'disable syn' then 'set synch' to your primary syn source on the 'display syn' page, then 'enable syn'.

 

[VoIPgirl]

I went through all those and it is still showing Maintenance Name: TONE BD. I have not changed the synch plan in a long time. Can this just happen?
Thanks

If the pbx sees too many errors on the primary syn source for the pbx, and there is no secondary source, then it will stay on the tone board. In this case, you would probably want to contact the provider of that t-1 and have them do a 'stress' test after hours when u are not using the line to see if they can't narrow down where the problem is.
copy and past your 'display syn' page into this forum.

Stratum: 4
Primary: 02A15 Secondary: 02C14
Location Type Slip
02C12 DS1 y
02C14 DS1 y
02A14 DS1 y
02A15 DS1 y

Thanks

You only need to have slip detection 'Yes' on the Primary: 02A15 Secondary: 02C14 t-1s. But that isn't causing your problems.
Try to to set the the syn on the secondary t-1 o2c14

 

[VoIPgirl]

Are you saying to change the primary to the secondary? To set the sync, don't I need to do a ch sync? I don't believe that we get clocking from our secondary source, which could also be a problem. I probably have to call both carriers to have them check them for slips after hours and have the secondary one enable clocking/timing.

I am just not sure why some faxes are fine and some are not..

Thanks

 

[orypecos]

do 'disable syn' then 'set synch' to your seconday syn source o2c14 on the 'display syn' page, then 'enable syn'.

 

[VoIPgirl]

but there is nowhere to change the sync on the display sync page? Maybe that is where I am confused.
Thanks

at the command line type "Change Sync" this will give you the ability to change it. Being this is a PRI have you checked the status of you signal group? It's rather hard to have a PRI operational and not have a clock from the network. you may have other troubles that your not aware of.

 

[VoIPgirl]

That is what I did, (the change sync command). I am looking into other issues. Normally this PRI is fine for our clocking. We only use it for clocking. Our primary is the only one that has "clocking". I am going to call the provider. I still just think it is weird that all my faxes are coming through fine, but a customer of mine sent faxes that were half page faxes and smeared. Calls go through our Definity to a fax server that we have. What are you speaking of checking the signal group?

Thanks for your help!

 

[VoIPgirl]

On the interface of my primary clocking source, I have a red light in the third position and green lights in position 4 and 5. Does this help at all?
Thanks

 

[VoIPgirl]

Does the Definity have internal timing that I can use? Our provider is not providing the timing. This is the whole issue.

 

[orypecos]

The tone clock provides timing for the definity when you don't have t-1s, but when you have t-1s the timing needs to come from the central office unless you system is part of a dcs network. If that is the case, then timing needs to come from what ever is your master pbx in the network. The master still gets the timing from the central office at their location.
There is special timing source that AVaya use to sell that gives timing, but last time I heard only 3 were used in the whole planet cuz the central office is better.

 

[VoIPgirl]

Okay. Now provider is going to supply the timing. I have primary at 02C14 and Secondary 02C12. When I do a 'st sync', It says

Stratum Level 4
Maintenance Name: TONE-BD Physical Location: 02A
Switching Capability: Enabled
Excessive Reference Switching: No

02A is the physical location of the old primary.

I tried to do 'disable sync' 'set sync 02C14' then 'enable sync'

Thanks for the help!

 

[orypecos]

Well if have tried to also set the syn to the secondary ds1 and the pbx still goes back to the tone clock, then I would say that there may be other problems involved, as kentech04 (Programmer), has suggested.

We might not be able to resolve your problems in this forum. You might have to call your local vendor and have them dial in or call Avaya Technical Service Center. There are also other providers of remote techical service assistance, but I can't suggest any because I have no idea of the quality of service they provide.
I do know that the quality of service from Avaya Technical Service Center can be excellent to terrible depending on the technician you happen to get.

 

[VoIPgirl]

Thanks. I am having a tech come in to sync the circuit up. Hopefully this will solve the problem.

Thanks for all the help.
