Direct connection from IPO PRI Card to Diva Fax Server T1/PRI Card 1

[ega218]

Hello,

I have been able to configure the Diva Sever Card to emulate NT and configure the PRI card on the IPO as a normal connection to a Telco.

The conection seems to be working ok, except the connection between both cards keeps going up and down. Can not hold a connection more than 2 seconds.

I have tested both IPO PRI card and Diva Sever card when connected to PRI directly and working fine.

Note that I have created a cross over cable and made sure that they were crossed correctly 1/2 & 4/5.

The connection keeps going on and off. Could it be a voltage issue? As I can also hear a clicking noise on all of the phones on the IPO side, when the connection is made.

Any ideas? Thank you.

The clicking sugests a posible frame synchronisation problem

What is the clock quality set to on the 2nd pri card?

 

[ega218]

It is set to Network.

Thanks for your interest in this matter )

I would change it to either fall back or not suitable
only the main pri circuit should be set to network

 

[ega218]

I've now changed the clock quality to "Not Suitable" and "Full Back". However, I still have the up and down every three seconds and a cliking sound.

Any other ideas?

hmm, I am now working in the dark, but you could try setting the line signaling to CO, this looks like a new setting in V2.1 to make the Pri emulate the network

I have never used it myself, but it is worth a go.
acombination of these settings & those on the Diva should hopefully get thing working

Otherwise it looks like it is over to morrack

Thank you IPGuru for all your help.

Unfortunately, I have tried your suggestions and I am still getting connection up and down.

I will try next to connect a direct ground to the IP office units.

Someone from AVAYA suggested that I connect pass the connection through a DSU/CSU. I will try this tomorrow.

Any other suggestions from anyone else is welcomed.

I was able to make it work by changing the config on the Avaya PRI card.

I selected the DSU box (Which is on the 2.1 (15) version.
Then I also, slected CO for the Line Signalling.
However, I left the Clock Quality at Networked.

I can now receive faxes going to the Fax Server, with the short code giving to me by IPGuru:

However, when I reverse the shortcode and I setup an incoming call route as follows:

Line Group ID: 1 (which is the line group for the PRI card going to the Fax Server Card)

Incoming Number: (Left Blank)

Destination: FAX_out (short code pointing all calls to go through the primary PRI card connected to the Telco PRI)

Bearer Capability is set to Any.

When I attempt to send a telephone call by dialing 9 first, Avaya passing the digits to the PRI.

 

[IPGuru]

1 obvious solution is to NOT dial 9 from the fax.

Otherwise try a LINE short code of 9N, number N feature Dial.

Again I havnt tested this so keep experimenting & good luck
