DXC multiservice access nodes provide 50 millisecond backup of radio links in a ring topology, using drop-and-insert of E1s at each site. The DXC-30 placed in the base station controller duplicates up to 15 E1 links for 1+1 redundancy. The DXC-8R offers carrier-class redundancy in a compact, cost-effective unit that is ideal for crowded base stations. This application ensures reliable backhaul of cellular traffic.

This backup solution requires the RAD DXC only. Alternative backup solutions require costly investments in additional radio transmitters, transceivers and licenses.

This solution can also be achieved with the Optimux-T3 (instead of the DXC) for radio links with a T3 interface.
