 Processes Abis/Iub/S1/X2 interface protocols.
 VSWc2/VSWd1/VSWd2 accomplishes LTE control plane and service plane
protocols processing and 5G transmission transferring, including S1AP, X2AP,
RRC, PDCP etc. or accomplishes 5G control plane and service plane protocols
processing and 5G transmission transferring.
 VSWc0 accomplishes LTE control plane and service plane protocols processing,
including S1AP, X2AP, RRC, PDCP etc.
 Supports Ethernet switching function and implements data switching for service and
control flow within the system.
 Supports software management and local/remote BBU software upgrading.
 Supervises the running status of each board within the system.
 Provides LMT interface for local O&M.
 Provides GPS interface and GPS receiver management.
 Supports synchronization to various clock sources, including GNSS, IEEE1588,
1PPS+TOD, and SyncE. It can select one according to the actual configuration.
 Provides a real-time clock for system operation and maintenance and calibrates the
real-time clock.
 Manages hardware management information, including that of racks, slots, boards,
software versions and board function configurations.
 Provides a USB interface for software upgrading and base station commissioning.
2.2.2 Baseband Processing Board (VBP)
VBP is the baseband processing board, which processes the physical layer protocols
and frame protocol specified by 3GPP. There are seven types of BP boards: VBPc0,
VBPc1, VBPc5, VBPc7, VBPd0, VBPd1 and VBPd2.
