Figure 8 - nanoBTS Connections
1.7.1 Ethernet
Each nanoBTS must be connected to an Ethernet switch or hub via either a 109
ip.access single power inserter or 126 ip.access Powered Ethernet Switch. Refer to
CENG0033 for details of the power supply connections.
1.7.2 Timing Interface Bus (TIB) – Multi-TRX only
The Timing Interface Bus (TIB) is used to provide clock and signaling between the
nanoBTS when operating in a Multi-TRX configuration.
The TIB OUT from the Master TRX must be connected to the TIB IN of the slave
TRX. This in turn has its TIB OUT connected to the next TRX in the chain. See
