Is it possible to connect OXE PRA and AVAYA PRA with CAT6A cable without any E1 modem as intermediate When the distance between both PABX around 300 m
If so what are the cable pairs for Tx & Rx

Hi
It might work due to the quality of cable. Altough technical documentation refers to 300 m max length for this kind of interface. The quality of cable will be the key for this kind of connection. But I would not do it. Have you ever thought about fiber media converter or SIP trunk?
Best regards.

Hi !
The E1 is carried over a G703 line, specs. is around 1000-1200 m , We have succesfully running a crystal over this for many years. BUT be aware of
the overvoltage in BOTH ends of the cable to protect the system and the cable.

Hi !
We use a twisted pair of normal telecom std (0.7 mm DC- 1Mhz with prot. shield and self sealing for evt. water damage) will do.
But we used a 10 pair cable for mechanic strenght and took 2 non adjacent pairs from the pack. It had a outer shield that we connected to the (metal)protected earth. (same point as the grounding of the lightning protectors).

But we can connect with Both PRA by CAT6A cable (1,2 Tx pairs,4,5 Rx pairs ) oxe side and avaya side (4,5 Tx pairs,1,2 Rx pairs )where distance between two pabx more tan 280 m

Yepp, indoors no problem, but outdoors , cable in the ground no no. Still it is advised to protect the cable/eq. for overvoltage. So use a CAT6E.
