Service providers and enterprises have invested significant time and resources into dedicated T1/E1 transmission systems. Based on TDM (Time Division Multiplexing), these circuits have been very popular and effective for voice and data long distance services, dedicated private lines and last mile access, but they are expensive.
There is a demand for a more cost effective solution that can reduce the dependency on leased lines and ease the transition to all-IP networks. Wireless broadband has proven to be an economical and reliable option. The PTP 650 Network IDU (NIDU) is a hardware device which enables the passing of T1/E1 TDM circuits over PTP 650 fixed wireless broadband connections. Using the NIDU, information from existing TDM circuits is delivered reliably, meeting the precise latency and jitter requirements needed for T1/E1 traffic. The NIDU combined with the PTP 650 delivers TDM traffic today while easing the migration to all-IP networks in the future whether for enterprise applications or Macro-cell backhaul for 2G/3G traffic.
