The scheme of this network configuration is reported hereafter in figure 2.19.

Fig. 2.19: Block diagram for a triple-band system with duplexed base stations. This

scheme involves a rack-based Master Unit, with 8-TFLN optical TRXs and 32 TFAx

remote units.

Let’s assume we need to expand our network in a wider area, by using a

second subrack station at a distance of up to 20 km from the site where the

main subrack station is located.

This new network configuration requires to use an interconnect link, whose

master side will be at the main subrack station, and whose slave side will be at

the new remotised station.

The scheme of this new network topology is shown hereafter, in figure2.20.
