M2000 The M2000 provides integrated fault management for all NEs in the entire network. Through this function, you can monitor, handle, and export alarms, customize the notification modes, and perform correlation analysis. In this way, you can detect network faults in time and then perform the related operations. Alarms Alarms Severities

-Critical The device or resource may be no longer available. The fault must be removed immediately.

-Major The Quality of Service(QoS) of the device or resource decreases greatly. Proper measures must be taken to recover the service.

-Minor The QoS of the device or resource decreases slightly. Proper measures must be taken or further observation need to be done to avoid more severe faults.

-Warning The QoS of the device or resource may be affected. Proper measures must be taken. Alarms /Events

Alarm Category

Definition Related Concept Impact Handling Recommendation

Fault alarm

A notification that the system provides when it detects a fault.

A fault is a physical or logical factor that causes the system to fail. For example, Central Processing Unit(CPU) busy, hard disk failure, or network cable disconnection.

The system probably cannot work properly.

Can be cleared.

Clear the alarm to restore the system to normal.

Event alarm

A notification that the system provides when it detects an event.

An event is a situation of the managed object. For example, succeeded in periodic export of operation logs.

Events occur all the time. They have no negative impacts on the system.

Cannot be cleared, but can be acknowledged and unacknowledged.

You do not have to handle the event.

Radio Resource Control

Radio Access Bearer

BBU: The BBU3900 is a baseband processing unit that provides the interface for connection between the NodeB and the RNC. BBU Functions: - Providing ports for data communication between the NodeB and the RNC - Providing the CPRI interface for communication between the BBU and the RRU or the RFU - Providing USB ports, one of which facilitates NodeB upgraded when a USB disk is inserted during software installation and data configuration - Providing OM channels between the BBU and the LMT or the M2000 to operate and maintain the BBU - Processing uplink and downlink baseband signals - Managing the entire NodeB system in terms of OM and signaling processing - Providing the system clock BBU Models (Movistar): -3806 -3900 RRU: The RRU is an outdoor remote radio unit. RRU Functions: - Forwards and processes RF signals between the BBU3900 and the antenna system. - Receives RF signals from the antenna system, down-converts the signals to IF signals, and then transmits them to the BBU or the macro NodeB after amplification, analog-to-digital conversion, digital down-conversion, matched filtering, and Digital Automatic Gain Control (DAGC). - Receives downlink baseband signals from the BBU or the macro NodeB, forwards data received from its cascaded RRU, performs filtering and digital-to-analog conversion, and up-converts RF signals to the TX band. - Multiplexes RX and TX signals over RF channels, which enables the RX signals and TX signals to share the same antenna path. In addition, the RRU filters the RX signals and TX signals.

RRU Models (Movistar): -3801C (40W)

-3801E (40W) -3804 (60W) -3942 (120W)

Transmission Ports

BBU3900

UPEU The Universal Power and Environment Interface Unit (UPEU) is a mandatory board of the BBU3900. It converts -48 V or +24 V DC power to +12 V DC power. FAN The FAN is the fan unit of the BBU3900. The FAN controls the fan speed, detects the temperature of the fan board, and dissipates the heat in the BBU. WBBP The WCDMA Baseband Process Unit (WBBP) of the BBU3900 processes baseband signals. WMPT The WCDMA Main Processing and Transmission unit (WMPT) processes the signals and manages the resources for other boards. UTRP The Universal Transmission Processing unit (UTRP) is the transmission extension board of the BBU3900. It provides eight E1s/T1s, one unchannelized STM-1/OC-3 port, four electrical ports, or two optical ports. UFLP The universal FE/GE lightning protection (UFLP) board is a universal FE surge protection unit, each UFLP supports 2-way FE surge protection.

UELP Each Universal E1/T1 Lightning Protection Unit (UELP) provides surge protection for four paths of E1/T1 signals.
