Installing CPRI and OBSAI Links Between an RE and REC
Our experience working with large service providers in Asia and North America shows that ensuring a quality customer experience requires verifying the link between the radio equipment (RE) and radio equipment controllers (REC). These links comprise dark fiber, a DWDM network, or CPRI over OTN. Eliminating dropped calls because of missed handoffs or errors in baseband processing and poor data throughput caused by TCP packet retransmissions requires verifying Layer 1 and 2 parameters, like error-free transmission and delay.
