RCU for Radio Communication
The RCU antenna for a radio modem is connected to the BS antenna via the uplink DC,
provided the RCU and the WRH operate in the same cell system. Otherwise, the modem
must have a separate antenna. Data is transferred between the WRH and the RCU via the
P130 modem port on the RCI or FON. The RCU is also powered via the same port and has a
battery with enough capacity to send a number of alarms if a main power failure occurs.
RCU for Telephone Line Communication
The land line version uses a telephone line connected to a terminal block on the RCU. A free
strain relief bushing at the bottom of the WRH is used for the external telephone line cable.
Repeater-to-Repeater Link (R2R)
This section briefly describes the R2R network. Node configuration for the R2R network is
described in the OM-Online User’s Manual. The R2R network is a Powerwave specific
network that can handle up to 13 nodes, one or several of which being a gateway for
communication with OM-Online or OMS via modem.
Sliding Window (SLW) is a Powerwave specific protocol developed for the R2R network. The
SLW protocol and the IP protocol do not support each other and they cannot be mixed in any
node.
