					UBBPD5 WD2DUBBPD500 022HEL network Refrigeration Equipment 
				 
					Applications: 
				 
					All UBBPD5 WD2DUBBPD500 022HEL series Gigabit Ethernet ports can receive and process pause frames from other devices. However, not all UBBPD5 WD2DUBBPD500 022HEL series Gigabit Ethernet ports can transmit pause frames to other devices, identifies the Catalyst Gigabit Ethernet switches, modules, and ports that can transmit pause frames to other devices.

					What is UBBP? 
				 
					The universal baseband processing unit (UBBP) can serve as a baseband processing board working in any mode. 
				 
					A UBBP board can be configured in either a BBU3900 or a BBU3910. 
				 
					
 
					
 
					
 
					The UBBP performs the following functions: 
				 
					
 
					
						 Multiplexes baseband resources among different modes, thereby supporting multimode concurrency. 
					
						  Provides CPRI ports for communication with RF modules and processes uplink and downlink baseband signals. 
					 
					
 
					
 
					What are the types of UBBP boards? 
				 
					From SRAN9.0 onwards, UBBP boards are classified into the following types: UBBPd1, UBBPd2, UBBPd3, UBBPd4, UBBPd5, UBBPd6, and UBBPd9. 
				 
					All UBBP boards have the same appearance: On the upper left of a UBBP panel, there is a silkscreen "UBBP". On the lower left of a UBBP panel, there is a label indicating the type of a UBBP board. 
				 
					
 
					What modes are supported by UBBP boards?
