Abstract
A system for providing network management access to RF outdoor units of a point-to-multipoint wireless network. Network management signals from a network management system (NMS) are transmitted from an outdoor unit (ODU) receiver to destination ODU transmitters via modulation of a low frequency carrier over a frequency reference interconnection carrying a frequency reference signal. The frequency of the carrier is lower than the frequency reference avoiding any interference between the signals.
