1.2 Position of the IPCLK1000 in
the Network
The position of the IPCLK1000 in the network and
the features of the IPCLK1000.
1.1 Introduction to Clock over IP
With the development of IP networks, IP transport is applied to most communications
networks. The IP network, however, is an asynchronous transport network. The equipment on
an IP network fails to extract clock signals from the physical links. Therefore, a new way of
clock acquisition is required for the network equipment.
As a low-cost IP clock solution, 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) or building 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. In this way, the server provides the client with a synchronization clock that has
the hold characteristics.
1.2 Position of the IPCLK1000 in the Network
By adopting the clock over IP technology, the IPCLK1000 provides a cost-efficient IP clock
solution, and is mainly used on the following BSs: the BTS in the GSM, the NodeB in the
WCDMA, the AP in the uBro, the WiMAX, and the LTE.
The IPCLK1000 V200R003 supports both Huawei proprietary protocol and the IEEE 1588v2
protocol.

1 Overview of the IPCLK1000
The IPCLK1000 V200R003 is mainly used with the clock solutions to the GSM, WCDMA,
uBro, WiMAX, and LTE.
The typical application scenarios of the IPCLK1000 V200R003 are as follows:
Deploying the IPCLK1000 on a UMTS network
As shown in Figure 1-1, the IPCLK1000 provides IP clock packets to the UMTS base station.
The UMTS base station receives the IP clock packets from the IPCLK1000 through the IP
network, and recovers the required clock signals. The IPCLK1000 transmits the IP clock
packets to the AP through the SeGW tunnel, and uses the SeGW tunnel to ensure
communication between the IPCLK1000 and the AP.

2 Feature Description of the IPCLK1000
2.1 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.
Supports clock and time synchronization.
Supports clock packet capture.
Supports clock packet statistics.
Supports operation and maintenance (OM) on the Local Maintenance Terminal (LMT) or
M2000.
2.2 Clock Signal Processing
2.2.1 Input and Output of Clock Signals
Clock Source Input
The IPCLK1000 provides access for multiple clock sources. The system clock can be chosen
in a convenient and flexible manner.
The IPCLK1000 supports the following types of clock sources:
Building integrated timing supply system (BITS) clock
External 8 kHz clock, which is a standard 8 kHz clock provided by an external device
Global Positioning System (GPS)/Global Navigation Satellite System (GLONASS)
clock
External 1PPS (1 pulse per second) clock
The IPCLK1000 requires the frequency accuracy of all clock sources to be better than stratum
2, that is, ±0.016 PPM.
For the IPCLK1000, non-standard clock sources need to further meet the following
requirements:
10 MHz clock supplied by BITS: RS422 level; the duty ratio ranges from 45% to 55%.
External 8 kHz clock: RS422 level; the duty ratio ranges from 45% to 55%.
External 1PPS clock: RS485 level; high levels should last more than 1 ms.
NOTE
The IPCLK1000 can obtain clock signals either through the built-in satellite card or from an external
satellite card through the clock signal input ports on the panel.
Clock Signal Output
The IPCLK1000 can provide clock signals whose frequency variation is less than ±50 parts
per billion (ppb). The output clock can be configured to be 10 MHz or 2.048 MHz. The output
clock signal is used only for tests but cannot be used as a clock input source for any other
device.

2 Feature Description of the IPCLK1000
2.2.2 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 oscillator
as the clock source input.
Manual: The input clock signals at a specific port are manually set to be the clock source
input.
Auto: Based on the priorities of the clock sources, the IPCLK1000 automatically selects
the clock signals imported to a specific port as the clock source input. If the clock source
is faulty, the IPCLK1000 then automatically switches to a clock source that takes priority
over the rest available clock sources.
2.2.3 Synchronization
As an IP clock server, the IPCLK1000 sends IP clock packets to a base station so that the base
station can parse the clock packets and recover the clock from the packets. Base stations can
recover clocks from IP clock packets only if intermediate networks transporting the packets
have a jitter less than 20 ms and a packet loss rate less than 1%.
The IPCLK1000 can send IP clock packets to a maximum of 10,240 home APs at the same
time at the following frequency:
For Huawei proprietary protocol, you can set the packet sending frequency to 1, 10, 20,
30, 40, or 50 packets per second. Under default configurations (50 packets per second),
IP clock packets from one base station generally occupy a bandwidth of 30 kbit/s, and
clock synchronization can be ensured if previously described transmission quality
requirements are met.
For the IEEE 1588v2 protocol, you can set the packet sending frequency to 1/2, 1, 2, 4, 8,
16, 32, 64, 128, or 256 packets per second. In unicast mode, the packet transmission
interval can be up to 128 packets per second. In multicast mode, the packet transmission

If no operation is performed during a certain period, the user interface is automatically locked.
SSL security management mechanism
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 the
transmission.
Configuration Management
Configuration management is mainly applied to equipment maintenance and data
configuration.
For configuration management, the IPCLK1000 performs consistency check on configuration
data. Two data configuration modes are available: dynamic data configuration and static data
configuration.
In dynamic data configuration mode, the modified data takes effect immediately.
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.
Software Management
For software management, the IPCLK1000 has functions such as software version
management and software upgrade. You can query the software for its version. You can also
upgrade the non-compliant versions to compliant versions.
Alarm Management
The alarm management system of the IPCLK1000 detects and reports fault information in real
time. The LMT or M2000 then displays the alarm information and provides appropriate
handling suggestions.
The alarm management system of the LMT or M2000 is connected to an alarm box through a
serial port. It provides audio and visual indication of alarms generated by the alarm box.
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 the
IPCLK1000, the system saves the records. The size of the log file is limited to 1 Mbit/s, and
the extra data overwrites the original one when the size exceeds the limit. You can run the
ULD FILE command to upload the OM log to the FTP server. The log can be retained as long

-
One more IP address can be configured for a service port on the IPCLK1000. Generally, the original IP
address of a service port is called the primary IP address, and the new IP address configured for the
service port is called the secondary IP address. Note that the primary IP address and the secondary IP
address cannot be set in the same network segment.
A NodeB does not require a secondary IP address.
In the uBro, the IPCLK1000 requires a primary IP address and a secondary IP address when
providing clock sources for APs. General messages of the IEEE 1588v2 protocol are
transmitted by the IPCLK1000 at its primary IP address, and event messages of the IEEE
1588v2 protocol are transmitted by the IPCLK1000 at its secondary IP address. All
proprietary protocol packets are transmitted by the IPCLK1000 at its secondary IP address.
Event messages of the IEEE 1588v2 protocol contain timestamps. The receive end extracts timestamps
to recover time information. General messages do not contain timestamps.
For the use of a primary IP address, an IPSec tunnel must be configured on the firewall side;
for the use of a secondary IP address, NAT mapping must be configured on the firewall side.
For details on the configurations, see the documentation regarding to the uBro.

The IPCLK1000 supports active/standby workspaces.
The space for storing version files of the IPCLK1000 is divided into an active workspace and a
standby workspace. The workspaces store different versions of files.
The active/standby relationship is relative. It is subject to the active software. The workspace that
stores the active software is called the active workspace, and the other one is the standby workspace.
Prerequisites
The FTP server works properly. It is located in the same intranet as the IPCLK1000. The
two communicate properly.
No firewall exists between the FTP server and the IPCLK1000.
The specified user name and password for login to the FTP server are correct. In addition,
you have the right to read the specified directories.
Procedure
Step 1 On the MML client, run the DLD SOFTWARE command to download the required host
software to the standby workspace on the IPCLK1000.
You must enter the IP address of the FTP server, user name and password and specify the save
path.

4.7 Reconfiguring the IPCLK1000
The data of the IPCLK1000 is initially configured before delivery. Therefore, you need to
only modify the related data on site, based on the field situations. For details, refer to section
4.2.3 "Planning Data." This section describes major data reconfiguration tasks.
4.7.1 Changing the Service IP Address of the IPCLK1000
If the service IP address preset before the delivery of the IPCLK1000 does not comply with
the network planning, you should change that IP address to the planned IP address.
To change the service IP address of the IPCLK1000, do as follows:
Step 1 On the MML client, run the SET ETHIP command, and set the port type to SERVICE to
change the service IP address and the subnet mask. If the service IP address needs to provide
NAT mapping with the firewall in the uBro, select Yes in Add Flag. Then, change the bound
IP address and subnet mask.
Do not set the subnet mask to 32 bits, that is, 255.255.255.255.
After you run the SET ETHIP command, you need to reset the IPCLK1000 to validate the
configuration.
Step 2 (Optional; required when the IPCLK1000 and a client are located on different network
segments) On the MML client, run the ADD IPRT command to configure a route for the
service port, through which the IPCLK1000 is connected to the client.
Alternatively, configure a route for the service port when the IPCLK1000 is actually
connected to a client.
In the uBro, the next hop address for a default route will be the next hop for the primary IP address if
both the primary IP address and secondary IP address of the IPCLK1000 are configured. For the use of
the secondary IP address of the IPCLK1000, a route does not need to be configured.
----End
4.7.2 Changing the OM IP Address of the IPCLK1000
If the OM IP address preset before the delivery of the IPCLK1000 does not comply with the
network planning, you should change that IP address to the planned IP address.
This section assumes that the remote OM terminal is ready while you are performing local
commissioning for the IPCLK1000. After this procedure, the IPCLK1000 is connected to the OM
terminal.
To change the OM IP address of the IPCLK1000, do as follows:
