TLU 76/1 interconnection Cisco 2800, HELP!!!

[rightsaidfred]

Hi All,

I have just programmed a Tlu76/1 card for an interconnection with Cisco 2800.
I want to connect it with TSR 9010481 (RJ45) but I cannot make the connection work.
Both router and Md110 side is blocked and shows alarm.
I have checked and tried everything:

-The router works with a public isdn pri, alarm disappears.
-The PBX's tlu76/1 card also works with public isdn pri.
-I tried through the MDF and directly from card to the router.

As far as I know on TLU76: C26,28,30,32 is used and on the router pinout is: 1,2,4,5

-I tried to change the pairs and the polarity but didn´t help!

Do you have any idea what can be the problem?

If I use RJ45 connection to the router and not Coax is there a difference between the configuration?

Thanks

Do you have correct parameters? Check the Cisco home page for MD110 connection.

If they both work when you connect a public ISDN line on them then they are both set as terminal side. One of them should be network in order for the connection to work.
Why are you using ISDN Pri instead of qsic?
Hope this reply helped you.

Did you connect it in the the fourth connector (at the bottom)?

Now working!
My problem was that TSR 9010481 cable connector was upside down at the card end.
