E1 Lineside Care, Connecting to Dialler, Tone Generator?

[rorton]

Hi All

Still trying to get our dialler to dial over an E1 connection.

At present, we have a server with an Intel D300 Dialogic card, connected to an E1 lineside card in our Option 81 Switch.

The link is up, no alarms at either end, but we cant get the dialler to dial over this link

We have 30 analogue 500 sets configured on the E1 card, and the DN's are aquired.

The only thought i have is that we may not have a tone detector car on the shelf that the E1 card is installed. Im not local to the site so cant tell from looking.

Would a tone detector card be required for an E1 lineside card? The think that is leading me to think is, is that on our dialler server, we are getting 'no ringback tone' in the logs.

Any help apreciated, am tearing my hair out now!

YOU WILL NEED A DTR CARD SOMEWHERE IN THE SWITCH, AND IF THIS IS A WAR DIALER YOU MAY NEED MORE THAN 1. MAKE SURE YOU HAVE DTN IN THE CLS FOR THE ANALOGS. AFTER THAT YOU START LOOKING AT THE SERVER

Hi Rorton
We are connecting an E1 line side to a server using the D300 cards, but we can't establish a link. Can you tell us what cabling set-up your are using & what drivers you have loaded for the card.

Thanks

Hi, we are using the usual v6 intel diaogic software, no special drivers required as long as they appear in device manager on your box (they are plug n play)

With ref to the cable, we have a cat 5, with RJ45 at each end. The pin connections are:

1 RCV_Ring 1 XMIT_Ring
2 RCV_Tip 2 XMIT_Tip
3 Chassis Ground 3 Chassis Ground
4 XMIT_Ring 4 RCV_Ring
5 XMIT_Tip 5 RCV_Tip
6 Chassis Ground 6 Chassis Ground
7 Chassis Ground 7 Chassis Ground
8 Chassis Ground 8 Chassis Ground



1 – 4

2 – 5

3 – 3

4 – 1

5 – 2

6 – 6

7 – 7

8 – 8


This Cat 5 connects to the RJ45 on the D300 card (we are using a 120ohm, not 75 ohm coax) and then into a rj45 to coax converter/balun. This then conncts to the 4 way cable coming out of the Meridian to the coax connectors there.

The thing you need to check, is that CRC is not switched on on the card. THis is what gave us the errors on the E1.

Good luck, post back inf you need any more info.

Many thanks Rorton.

I have a couple more questions!

So the RJ45 lead from the Dialogic card to the PBX is a cross-over cable and NOT a straight through?

I am assuming you then connect into a pre made rj45 to 15 pin D way convertor which inturn connects to the E1 card via cable P2 on the back?

We have had to make up this conversion ourselves and I was hoping you could confirm the pin out configuration, this is what I have done.........

RJ45 15 pin D way
1 3
2 11
4 9
5 1

For information I can get both a green light on the dialogic card and also get all channels on the E1 card into an idle state by plugging s cable into both and shorting/loop back with the wires, proving correct setup for both cards. However as soon as we connect the devices together we get a red light on the Dialogic card and all channels on the PBX go into busy state.

Any info would be great.

Thanks.

Hi

Yep, its not a true cross over, but crossed over as per the pinouts.

Im slightly confused by your next part of the chain.

If i look at our meridian, we have a cable from the back plane with 4 D connectors on.

From P2 on this loom there is a white 15pin Din to Coax converter.

From the coax converter, we have a small run (6 inch) of coax, which connects to a coax to RJ45 Balun. From the RJ45 Balun, we then run the above cable to the D300 Card.

I dont see any Coax runs on your setup, and i think you may be trying to convert from P2 on the loom directly to and RJ45?

If so, i dont think this will work. I was unhappy with all the cable convertions i have to to, coax, RJ45, 15 Pin Din etc) so spoke with our maintainer, who said there was a direct to twisted pair connection from the Meridian, but it wouldnt work with what we wanted, you HAD to convert using the above method.
