There is a scenario that current customer PBX using Nortel/OKI which support for number of analog phones(50units). The issue we encounter here is, there are few analog phone which distance more then 5km away from PBX room. Current PBX still able to support such distance.
Our objective here going to replace Nortel/OKI with CUCM and VG248. But as per VG248 spec. support distance is only up to 5000feet(1.5km). Thinking use ATA with fibre connection in between, but is not allow use fiber in between. The solution must be end to end COPPER wire only, and along the way cann't install any active device, except in PBX room.
any device can be install in font VG248 to boot up RJ11 signal support such distance ?
