Page19

USCU (The Universal Satellite card and Clock Unit )

USCUb0 Board

USCUb2 Board

•The USCU performs the following functions: •The USCU provides interface for an external RGPS device

(such as a reused device of the operator), BITS device, and TOD input

•The USCUb0 does not provide the satellite card •The USCUb2 supports GPS and GLONASS with two built-in satellite cards

Page20

Clock Synchronization Modes •

GPS Clock

•

If an eNodeB is synchronized with the GPS clock, the eNodeB obtains clock synchronization signals from the GPS through the USCU. In this case, both frequency synchronization and time synchronization are applicable

•

IEEE1588 V2 Clock

•

IEEE1588 defines the Precision Time Protocol (PTP), which targets precise synchronization of distributed and independent clocks in measurement and control systems, with the precision to microseconds. IEEE1588 V2 supports frequency synchronization and time synchronization

•

In LTE applications, high-accuracy frequency synchronization and time synchronization can be achieved between clock servers and eNodeBs by IEEE1588 V2 synchronization Page21

•

Clock Synchronization Modes (Cont.)

Clock over IP

•

•

Free Running

•

•

The clock enters the free running mode if no reference clock is available after the oscillator is warmed up or if the clock has lost its reference input for a period of time longer than the timer of the holdover mode

1 PPS

•

•

Clock over IP is a Huawei proprietary frequency synchronization technology, which is based on an IP clock server/client architecture. It supports only frequency synchronization

The eNodeB obtains 1 Pulse Per Second (PPS) signals to achieve time synchronization

E1/T1 Line Clock

•

An eNodeB can extract frequency synchronization signals from E1/T1 links at the physical layer. If S1 data is transmitted over an E1/T1 network, the eNodeB can be synchronized with the E1/T1 line clock
