2.5.4 Timing Interface Bus (TIB) – Multi-TRX only
The Timing Interface Bus (TIB) is used to provide clock and signalling 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 Figure 9.

2.5.5 Chassis Bond Strap – Multi-TRX only
When the nanoBTS is operated in a Multi-TRX configuration, each of the nanoBTS must
be connected together using the supplied chassis bond kit.
To fit the chassis bond strap, remove the nanoBTS from the mounting plate.
Using the screw provided, screw the Chassis Bond Strap to the screw on the rear of the
nanoBTS, see Figure 10 or Figure 11.
