Sometimes known as the F-interface, this is implemented in hardware as RS-232 for ASCII
communication protocol between OMT and the equipment.
Physical/Local Connection
RS-232 cable is supplied with equipment. It connects the serial port of the PC to the RS-232 port on
either MOU or RRU. For MOU, it is through the RS-232 port on the Main Control Unit, while for RRU, it
is through the RS-232 port located on the distribution board inside the RRU enclosure. Local
commissioning of ROU can be monitored through the RRU unit connected with it.
Remote Connection
An integrated wireless/wireline modem implementing the link (data and SMS mode) provides the
option for equipment remote connection over PSTN. SMS mode is available only for wireless modem.
For managing the ROU, a remote connection is achieved by in-band communication over the optical
fiber. The FSK modem within the MOU and ROU modulates the data between the equipments. Using
a PC communicating with the MOU, RF parameter and alarm information of the ROU(s) can be
viewed and managed.
