The network indoor unit (NIDU) enables up to eight (8) E1/T1 connections from the proven PTP650/670 radios. Send both TDM and Ethernet traffic over the same link to achieve seamless connectivity between locations. When combined with the PTP650 series radios, the NIDU is the perfect solution for business communications continuity or disaster recovery. Compared to pseudo-wire alternatives, the Cambium NIDU offers low latency, accurate timing across the link, and efficient use of capacity. Single management interface and simple configuration make setup a quick and easy process.
