IPCLK3000 Overview
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, 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 sy system stem (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 IPCLK3000 in the Network IPCLK3000 is cost-effective IP clock solution that delivers carrier-class and high-precision time and frequency synchronization for downstream devices. As a time server that complies with the IEEE 1588-2008 standard, IPCLK3000 provides high-density time input/output ports and can be connected to a large number of clients. IPCLK3000 V100R002C01 supports IEEE 1588v2-2008, ITU-T G.8265.1, ITU-T G.8275.1 、 ITU-T G.8272 and Huawei TOP protocols. IPCLK3000 V100R002C01 is used in the clock solution of a 2G, 3G, 4G/LTE, or WiMAX network The typical application scenarios of IPCLK3000 V100R002C01 are as follows:
Frequency synchronization
As illustrated in Figure in Figure 1-1, a 1-1, a network requiring frequency synchronization comprises base stations, the IPCLK3000, and intermediate transmission equipment. IPCLK3000 obtains its reference clock source from a GPS or BITS, and base stations obtain IEEE 1588 frequency synchronization information from the IPCLK3000 through the intermediate transmission equipment. Two Two IPCLK3000s work in an independent IEEE 1588v2 domain and back up each other.

Time synchronization
Different from a frequency-synchronized network, IPCLK3000 on a time-synchronized network can apply the Grand Master scheme or the Edge Master （for future study） scheme. Figure 1-2 illustrates the hop-by-hop IEEE 1588v2 deployment scheme, which requires that intermediate transmission equipment support IEEE 1588v2-compliant boundary clocks (BCs). On a time-synchronized network applying the hop-by hop IEEE 1588v2 deployment scheme, the IPCLK3000 implements time synchronization for the next-hop router or Ethernet switch, and base stations obtain timing signals from the last-hop transmission device, not from the IPCLK3000 directly.

All types of clock sources must have a frequency accuracy accuracy higher than stratum-2 clock standard, namely, namely, ±0.016 PPM. For the IPCLK3000, 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
IPCLK3000 integrates the GPS receiver and receive antenna into one module. It provides remote GPS (RGPS) ports on its front panel to output 1PPS signals and GPS system messages. The RGPS ports can meet meet disaster disaster-tolerance -tolerance requireme requirements nts or are use used d in scenarios scenarios where it is difficult difficult to la lay y out GPS cables or the distance between the GPS antenna and IPCLK3000 is greater than 300 m.
The IPCLK3000 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.
Currently, the RGPS port and the second GPS antenna port (labeled ANT-2 on the panel) are two reserved ports; if you need to use the two ports, please contact Huawei.
After clock sources are set, the IPCLK3000 can use one clock source as the current clock source input. The IPCLK3000 supports three modes for clock source switching: free, manual, and auto.
Free: The IPCLK3000 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 IPCLK3000 automatically selects the clock signals imported to a specific port as the clock source input. If the clock source is faulty, the IPCLK3000 then automatically switches to a clock source that takes priority over the rest available clock sources. For more information about priorities of the clock sources, see the online help for the SET SRVCLKMODE command.
2.1.3 Powerful Client Access Capability The IPCLK3000 is a case-shaped time server that provides powerful client access capability capability.. When the frequency at which packets are sent is 128 Hz in L3 unicast scenarios, an IPCLK3000 server can be connected a maximum of 2048 clients. Each of the four dedicated ports on IPCLK3000 can be connected to 512 clients. clients.

2.1.4 High-Precision Synchronization The IPCLK3000 supports built-in rubidium (RB) clocks and oven controlled crystal oscillator (OCXOs). When a GPS source is traced, clock accuracy complies with ITU-T G.811 and time accuracy is less than 100 ns. Even when the external reference source is lost, the built-in -11 rubidium clock of IPCLK3000 can have a frequency holding precision of 1x10 /day and a time holding precision of 1 μs/day. An IPCLK3000 which serves as a time synchronization server must be configured with RB clocks. As an IP clock server, server, the IPCLK3000 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. IPCLK3000s 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 IPCLK3000 can send IP clock packets to a maximum of 2048 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 1/16 Hz, 1/8 Hz, 1/4 Hz, 1/2 Hz, 1 Hz, 2 Hz, 4 Hz, 8 Hz, 16 Hz, 32 Hz, 64 Hz, 128 Hz, or 256 Hz. In unicast mode, the maximum packet sending frequency for SYNC packets can be set to 128 Hz in one_step mode and 64 Hz in two_step mode. In multicast mode, the maximum packet sending frequency frequency for SYNC packets packets can be set to 256 Hz in both one_step mode and two_step mode. Under default configurations (16 packets per second), keep the bandwidth for sending the IP IP clock packets packets at 12 kbit/s for each base base station. Ensure that the bandwidth does not exceed 190 kbit/s in a poor network environment.
2.1.5 Compliance with Various Network Protocols The IPCLK3000 supports various network protocols, such as IPv4, IPv6, PTP/IEEE 1588-2008, ITU-T G.8265.1, G.8275.1, NTP(Client), HTTP, HTTPS, FTP, and FTPS, among which HTTPS and FTPS guarantee reliable communication for the configuration and management port. NOTE
It is recommended that FTPS uses the encryption mode. Otherwise, security risks may result.
It is recommended that HTTPS uses the encryption mode. Otherwise, security risks may result.
2.1.6 Support for Customized PTP Templates For master ports, you can select PTP templates that comply with IEEE 1588v2-2008, ITU-T G.8265.1, or ITU-T G.8275.1, and configure different parameters for these templates. For slave ports, you can add clock links that comply with IEEE 1588v2-2008 and configure different parameters parameters for these links.

4.6 Managing Alarms and Events 4.6.1 Basic Concepts Related to Alarms or Events This section describes the basic concepts related to alarms and events.
Alarm A faulthas alarm is generated a hardware is faulty or astatus major is fault abnormal. Acan faultbe alarm a higher severitywhen than an event. Based on the offunction the faults, alarms categorized into active alarms and cleared alarms.
If a fault is cleared, the status of the alarm changes to cleared. This type of alarm is called a cleared alarm.
If a fault is not cleared, the status of the alarm remains active. This type of alarm is called an active alarm.
NOTE
You can search a database for cleared alarms.
Event An event notifies users of important information when the system is running properly. Users do not need to handle an event when it is generated.

5.1 Basic Commissioning of IPCLK3000 The data of the IPCLK3000 is initially configured before delivery delivery.. Therefore, you need to only modify the related data on site, based on the field situations. This section describes major data reconfiguration tasks.
5.1.1 Adding a Service IP Address for the IPCLK3000 By default, no service IP address is preset before the delivery of the IPCLK3000. Y You ou need to add a service IP address for the IPCLK3000 according to the network plan.
Step 1 On the MML client, run the ADD DEVIP command, and set the desired port, and add a service IP address and a subnet mask for the port.
CAUTION
Do not set the subnet mask to 32 bits, that is, 255.255.255.255.
Step 2 (Optional; required when the IPCLK3000 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 IPCLK3000 is connected to the client. NOTE
Alternatively, configure a route for the service port when the IPCLK3000 is actually connected to a client.
Step 3 (Optional; required when VLAN is configured for the service port on the client) On the MML client, run the ADD VLAN command to add a VLAN for the service port, ensuring that the IPCLK3000 and the client can communicate with each other. NOTE
Alternatively, add a VLAN for the service port when the IPCLK3000 is actually connected to a client. To query the VLAN, run the LST VLAN command. To delete the VLAN, run the RMV VLAN command.
Step 4 (Optional; when the IPCLK3000 is configured with VLANCLASS) On the MML client, run the ADD VLANCLASS command to add a VLAN subinterface s ubinterface for the service port. To query
