UTRP (The Universal Transmission Processing unit )
Optional, maximum 2 modules
The UTRP performs the following functions:
Provides ports for eight E1s/T1s based on the IP
protocol.

controls 256 HDLC timeslots.
Copyright © 2011 Huawei Technologies Co., Ltd. All rights reserved. Page23
USCU (The Universal Satellite card and Clock Unit )
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
USCUb0 Board USCUb2 Board

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
Copyright © 2011 Huawei Technologies Co., Ltd. All rights reserved. Page25
Clock Synchronization Modes (Cont.) Clock over IP
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
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 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
