PRA2 external pinout

[skipper-com]

Hi all!
I want to connect two E1 trunks to OXE PRA2 board. But I can not find any documentation in which explains pinouts for TY2 cable pairs: TxRINGa (TxTIPa), RxRINGa (RxTIPa), TxRINGb (TxTIPb), RxRINGa (RxTIPa). Help please. Thanks!

Yes, documentation contain pinouts for boards PRA2 and cable TY296PTSDIN indicated there T2TXb(1), T2TXa(1), T2RXb(2) and T2RX(2) but I don`t understand how to interpret these abbreviation. What in this abbreviation is the number of a trunk and pair of wires? I think T2TXa(1) is the first trunk transmit pin on the first pair (red wire). But in this case it is not clear tip or ring? As I understand it, for the two streams should be at least 8 wires in the documentation declared only 4. If you can, please explain? Thank you

The PRA board only accepts 1 E1 cct the pin outs are transmit + and - and receive + and -

The NPRAE however can have two E1's in which case I think that the first 2 quads on the cable are used (that would have to be checked though)
