v5.2 cable

[finafina]

I have to post this once again.

I need to connect two v5.2 interfaces.
The distance between them is about 50 meter.
How is the wiring ?
What kind or type of cable do i have to use ?
Is it similar to E1 cable ?

I never see v.52 port.
How is it look like ?
Is it a DB-connector, telco-connector or what ?
What are pinouts?

Could you tell me the links I can see the drawing ?
I appreciate your help.

Thanks.
