Thanks for the hospitality. We have done quite a few of these connections but this one is turning into a problem. I guess if it were easy everyone would be doing it!

The answer depends on what kind of Dialogic board you have, they come in two basic flavors. In either case the T1 type will be lineside.

The other settings will be either D4/AMI or B8ZS/ESF. D4/AMI is the older type and B8ZS/ESF is for newer boards. The same thing will apply to whether you have to roll the pairs or not. Older boards had to roll the pairs and the newer boards can go either way.

The leads you use are 1, 2 and 4, 5. 1&2 are the orange pair and 4&5 are the blue pair. If you need to roll, do the complete pair, 1&2 go to 4&5. Polarity is not relevant because the pair has one signal on it, either send or receive.

Now, how to discover this. From the Definity do a "test board (DS1 board) long", cancel the test after test 146 completes because you do not care about the rest of the tests. If test 138 fails you have a loss of signal. This is caused by two things, having a 120A CSU on the DS1 card and not telling the PBX you have one by setting CSU type to "Integrated" on the DS1 page, or you need to roll the transmit and receive pairs. If your problem is the 120A issue, correct the translations and test again. If the problem was not the 120A or you fail test 138 again, roll the pairs.

If test 145 now fails (or you did not fail test 13, then try changing the D4/AMI and B8ZS/ESF settings.

If you cannot get rid of the test 138 failure no matter what you do, then the problem is physical (meaning DS1 board, cable, Dialogic board) or programming in the computer with the Dialogic board.

Thanks one down one to go

You should be using B8ZF, ESF, with cross over cable, ethernet cable, reverse the pairs, and connect to either C120A, or the wall field, on the wall field its pair 22 & 23, I have not had any luck except with cross over cable.

MSYoung

If you use an Ethernet cable, examine it first and make sure it has all four pairs. Not all of them do and if it only has the two pairs that Ethernet uses, you only have half the circuit.

A store bought cable should be ok, but if someone there has been making patch cords, verify, verify, verify.

Hello and thank you for your help in getting the Dialogic T-1's up and running. We have run into a problem with transfering a call to an internal 4 digit number.

We have looked at our engine logs and everything appears to function properly until we dial the four digit extension. A #1 is being inserted before the four digit number giving an extra digit.

All help is appreciated

Thank You for your responses

Is this related to the problem in this thread or a new problem?

Same machines just a problem further down the road. Should I post a new thread?
