On the network shown in Figure 1
, the BITS interface that functions as the T-GM obtains high-accuracy time information from a global positioning system (GPS), encapsulates the information into a G.8275.1 packet, and sends the packet to the bearer network. A bearer network device that functions as the T-BC transparently transmits the time information to all devices on the bearer network. BCs send high-accuracy time information carried in the G.8275.1 packet to wireless access devices, such as a NodeB and a radio network controller (RNC).
