You will need either a TSR 901 0450/11000 (8 pair) or a TSR 901 0492/11000 (16 pair) cable from the front (bottom) of the TLU79. Terminate this on Krone strips as normal (ie: white/blue, white/orange etc). ISDN circuit 1 (Individual 0 ) will be presented on pairs 1 & 3 (RX & TX), Ind 1 will be 2 & 4, Ind 2 will be on 5 & 7 and Ind 3 on 6 & 8. The pairs are always the same but it depends how you terminate on the Krone (eg: missing out Krone positions 5&6 for cable balance or not). At the end of the day, taking Ind 0 as the example, pair 1 (Rx) will need to connect to pins 4&5 of the RJ45 and pair 3 will need to connect to 3&6 of the RJ45. I think that's right but if you have to reverse the pairs, that's no big deal, it can simply be done on the Krone strip. If hooking up to say BT ISDN 2e's for example, you could always terminate these on Krone strips and cross jumper the pairs as appropriate. Regards, gedii.
Yes, your understanding of the circuit pairs is correct. I thought I might have confused the issue a little. I think I'm right with the RJ45 side of things but I was going on memory and theory rather than checking a working installation. Please excuse any error here if you do find in fact that you have to reverse the pairs. Good Luck ! gedii.
I connect cable as advise by you. but i am getting alarms 269 digital trunks loss of frame synchronization.
How i can check that my configuration is ok.
