    1.1 Introduction to Clock over IPWith the development of IP networks, IP transport is applied to most communications

    networks. The IP network, however, is an asynchronous transport network. The equipment onan IP network fails to extract clock signals from the physical links. Therefore, a new way ofclock acquisition is required for the network equipment.

    As a low-cost IP clock solution, clock over IP serves mainly the base stations that do notrequire strict time synchronization. These base stations can be the NodeB or Access Point (AP)

    in a Wideband Code Division Multiple Access (WCDMA) network, the Base TransceiverStation (BTS) in a Global System for Mobile communications (GSM) network or Access Poin

    (AP) in a UMTS Boardband (uBro) network.

    Clock over IP is implemented by the IP clock server and IP clock client. The IP clock server

    obtains clock signals from a clock device, such as a Global Positioning System (GPS) orBuilding Integrated Timing Supply System (BITS) device. After local phase lock and hold,the server transmits IP packets through an IP network to the IP clock client, that is, a NodeB

    or an AP in a WCDMA network, a BTS in a GSM network or an AP in an uBro network. In

    this way, the server provides the client with a synchronization clock that has the holdcharacteristics.

    1.2 Introduction to the IPCLK1000

    1.2.1 Position of the IPCLK1000 in the NetworkThe IPCLK1000 is developed by Huawei. It mainly acts as the IP clock server for IP transport

    in a WCDMA, GSM or uBro network. The IPCLK1000 provides a clock for the base stationsto which clock sources are unavailable. The introduction of the IPCLK1000 does not affect

    the architecture of the network.

    IPCLK1000 V200R002 supports both Huawei private protocol and the IEEE1588 V protocol.

    This section takes the IPCLK1000 in a WCDMA network for example. Figure 1-1shows theposition of the IPCLK1000 in the WCDMA network.

    When some equipment in an IP network is unable to extract IP clock packets, the IPCLK1000

    can also serve as the IP clock client on that equipment side.

    Unless otherwise stated, this document assumes that the IPCLK1000 acts as the IP clock server.

    1.2.2 Network Security

    To provide clock to the AP, the IPCLK1000 sends the clock to the AP through the IPSectunnel. The IPSec tunnel applies security policies to the communication between the

    IPCLK1000 and the AP. To relieve the load in the IPSec tunnel, IEEE1588 V2 controlmessages and signaling messages are transmitted over the IPSec tunnel while the event

    messages are transmitted over the public network. Thus, In order to detach the transmission ofsignaling messages and event messages, the IPCLK1000 must be configured with two IP

    addresses, that is, a private IP address at the mobile core network and a public IP address. Theprivate IP address, that is, the primary service IP address, is used by the AP and the

    IPCLC1000 to transmit signaling and control messages in the IPSec tunnel, and the public IP

    address, that is, the secondary IP address, is used by the AP and the IPCLK1000 to transmitthe event messages over the public network.

    The communication between the IPCLK1000 and the NodeB does not have specific requirement on the

    network security.

    1.2.3 Features of the IPCLK1000

    The IPCLK1000 has the following features:

    Supports multiple clock source inputs.

    Provides clock source outputs for other devices.

    Supports multiple clock source switching methods.

    Sends IP packets as scheduled to IP clock clients for time synchronization.

    Is able to act as the IP clock client as required.

    Supports Operation and Maintenance (OM) on the Local Maintenance Terminal (LMT)

    or M2000.

    Supports clock packet capture

    Supports clock packet statistics

    1.3 Clock Signal Processing

    1.3.1 Input and Output of Clock Signals

    Clock Source InputThe IPCLK1000 supports the following types of clock source:

    BITS clock

    External 8 kHz clock, which is a standard 8 kHz clock provided by an external device

    External 1 Pulse Per Second (PPS) clock

    GPS or Global Navigation Satellite System (GLONASS) clock

    The IPCLK1000 can use its built-in satellite card to obtain synchronization clock signals.

    The BITS clock is categorized into the following types:

    Two 2.048 MHz or 1.544 MHz unbalanced clock inputs

    Two 2.048 Mbit/s or 1.544 Mbit/s unbalanced clock inputs

    Two 2.048 MHz or 1.544 MHz balanced clock inputs

    Two 2.048 Mbit/s or 1.544 Mbit/s balanced clock inputs

    Clock Signal Output

    The IPCLK1000 can provide lower-level devices with clock signals whose frequency

    variation is less than 50 parts per billion (ppb). The output clock can be configured to be10 MHz or 2.048 MHz.

    In addition, for easy recognition of whether the 2.048 Mbit/s or 1.544 Mbit/s clock source iscompatible with the IPCLK1000, the 2.048 Mbit/s or 1.544 Mbit/s clock signals can beconverted into 2.048 MHz or 1.544 MHz clock signals inside the IPCLK1000. The converted

    clock signals are further exported to the output ports, so as to facilitate verification of theclock sources.

    1.3.2 Switching Between Clock Sources

    After clock sources are set, the IPCLK1000 can use one clock source as the current clock

    source input. The IPCLK1000 supports three modes for clock source switching: free, manual,and auto.

    Free: The IPCLK1000 uses the free-run clock signals generated by the internal oscillatoras the clock source input.

  • 5/24/2018 IPCLK1000 User Guide

    IPCLK1000

    User Guide 1 Overview of the IPCLK1000

    1-4 Huawei Technologies Proprietary Issue 06 (2009-12-20)

    Manual: The input clock signals at a specific port are manually set to be the clock sourceinput.

    Auto: Based on the priorities of the clock sources, the IPCLK1000 automatically selectsthe clock signals imported to a specific port as the clock source input. If the clock source

    is faulty, the IPCLK1000 then automatically switches to the clock source that takespriority over any other available clock source.

    1.3.3 Working Principles of the IPCLK1000 as an IP Clock Client

    The IPCLK1000 can be configured to be an IP clock client and serve the device that isincapable of the IP packet resolution functionality.

    The IPCLK1000 in Slave mode parses the clock packets sent from the IP clock server,extracts clock signals from the packets, and then provides the clock signals to the required

    device such as a base station.

    1.3.4 Clock SynchronizationThe IPCLK1000 in Master mode sends IP clock packets to an IP clock client before the clientextracts clock signals from the packet.

    The IPCLK1000 frequency of sending the packets can be controlled as follows:

    For Huawei private protocol, you can set the packet sending frequency to 1, 10, 20, 30,

    40, or 50 packets per second. Usually, keep the bandwidth for sending the IP clockpackets at 30 kbit/s for each client. Ensure that the bandwidth does not exceed 50 kbit/sin a poor network environment.

    For the IEEE1588 V2 protocol, you can set the packet sending frequency to 1 packetevery two seconds or 1, 2, 4, 8, 16, 32, 64, or 128 packets per second. Usually, keep the

    bandwidth for sending the IP clock packets at 20 kbit/s for each client. Ensure that thebandwidth does not exceed 40 kbit/s in a poor network environment.

    The IPCLK1000 can send the IP clock packets to a maximum of 10,240 clients at a frequencysmaller than or equal to 32 packets per second. The total number of clients supported is

    decreased when the frequency is increased over 32 packets per second.

    1.3.5 Clock Packet Capture

    The IPCLK1000 can capture the clock packets in real time. The real-time capture of the clock

    packets enables the user to observe the message interaction on the M2000 or LMT client.Thus, the user can maintain the clock system by tracing the messages sent from the

    IPCLK1000.

    1.3.6 Clock Packet Statistics

    The IPCLK1000 provides statistics of the clock packets, including the number ofsent/received and abnormal IP clock packets at the application layer.

    1.4 OM Functions

    The following consoles are available for the OM of the IPCLK1000:

    LMT

    The LMT is applicable to local and remote maintenance. It is used to maintain a single

    IPCLK1000 from aspects such as software upgrade, data loading, alarm data collection,and equipment maintenance.

    M2000

    The M2000 is applicable to remote maintenance. It is used to maintain multipleIPCLK1000s from aspects such as software upgrade, data loading, alarm data collection,and equipment maintenance.

    Local maintenance: refers to the OM process where a user logs in to the IPCLK1000 by directlyconnecting an LMT to the local Ethernet port on the IPCLK1000.

    Remote maintenance: refers to the OM process where a user in an equipment room or at a networkmaintenance center configures IP routes on the LMT or M2000 to log in to the IPCLK1000 remotely.

    1.4.2 Introduction to OM Functions

    The IPCLK1000 provides the following main OM functions:

    Security Management

    Configuration Management

    Software Management

    Fault Management

    Log Management

    1-6 Huawei Technologies Proprietary Issue 06 (2009-12-20)

    1.4.3 Security Management

    For security management, the IPCLK1000 can protect the operator information by

    automatically locking the LMT application if no operation is performed during a period of

    time.Socket security layer (SSL) is added in the transmission link between the IPCLK1000 and the

    M2000/LMT. Thus, all MML and BIN instructions and messages can be encrypted during thetransmission.

    1.4.4 Configuration Management

    Configuration management is mainly applied to equipment maintenance and data

    configuration. For configuration management, the IPCLK1000 performs consistency check onconfiguration data.

    Two data configuration modes are available. They are dynamic data configuration and static

    data configuration. In dynamic data configuration mode, the modified data takes effectimmediately. In static data configuration mode, the modified data takes effect only after the

    IPCLK1000 is reset.

    The following commands are applicable only to static data configuration:

    SET CLOCKID

    SET CLIENTMODE

    SET ETHIP

    SET PTPFILE

    SET PTPPARA

    SET WORKSTATUS

    All the other commands are applicable to dynamic data configuration.

    1.4.5 Software Management

    For software management, the IPCLK1000 has functions such as software versionmanagement and software upgrade. You can query the software for its version. You can also

    upgrade the non-compliant versions to compliant versions.

    1.4.6 Fault Management

    The alarm management system detects and reports information about faults in real time. The

    LMT or M2000 then displays the alarm information and provides appropriate handlingsuggestions.

    1.4.7 Log Management

    The IPCLK1000 records the information about operations in real time. For example, when

    you perform operations and commissioning on the IPCLK1000 or alarms are generated on theIPCLK1000, the system saves the records. The size of the log file is limited to 1 Mbits, andthe extra data overwrites the original one when the size exceeds the limit. You can run theULD FILE command to upload the OM log to the FTP server. The log can be retained as

    long as you expect. In addition, you should specify the save path for the OM log, and thus youcan easily find the log, which helps locate and solve system problems effectively.

    1.5.3 Requirements for the IP Network

    QoS Requirements

    The Quality of Service (QoS) requirements of the IPCLK1000 for the IP network are the sameas the requirements for service data transmission. Table 1-2describes the specifications forthe IP network where the IPCLK1000 is located.

    Table 1-2QoS specifications for the IP networkItem Specification

    Delay < 60 ms

    Delay variation < 20 ms

    Packet loss rate < 1%

    Bandwidth Requirements

    Typically, each IP clock client requires 30 kbit/s bandwidth for transmission of clock packets.

    In a poor network environment, each client needs to increase the packet transmissionfrequency, thus requiring a maximum of 50 kbit/s bandwidth.

    1.5.4 Typical Networking Modes

    The IPCLK1000 can work in the following types of network:

    Layer 3 private network

    Layer 2 private network

    Internet-based public network

    Ethernet for the IPCLK1000 supports the following activities:

    Transmitting and receiving standard Ethernet II frames

    Receiving Ethernet 802.3 frames

    Transmitting and receiving Ethernet VLAN frames

    Transmitting and receiving standard TCP/IP data

    The IPCLK1000 has relatively low security guarantee. To enhance the security and reliability of theIPCLK1000 that accesses a network, you need to configure an external firewall.

    Layer 3 Private Network

    Service Ports

    The IPCLK1000 supports two types of port for services: GE optical port and FE port. The two

    types of port are applicable to different scenarios.

    The GE optical port is applicable to the situation where the field network uses only the

    optical port or where the field network uses both the FE port and the GE optical port butthere are more than 1,000 clients.

    The FE port is applicable to the situation where the field network uses only the FE port

    or where the field network uses both the FE port and the GE optical port but there arefewer than 1,000 clients.

    When the IPCLK1000 uses the GE optical ports, the optical module is required. This optical module is

    pluggable. You can replace it on site. For details about how to replace the optical module, refer tosection 5.3.2 "Replacing the Optical Module."
