Figure 19 – STEP 2.
Technical Description & Configuration Guide Configuration and Management Figure 22 – STEP 5. Checking settings and executing configuration To verify the settings, we can go to Status or the main screen, which is the first option in the navigation panel. If there are no „red fields‟, everything is set correctly and the link is up. Command Prompt Interface The LigoPTP 24 equipment can be monitored and configured by using command interface described in this chapter.
Technical Description & Configuration Guide Configuration and Management RS-232 Serial Management Port The RS-232 serial management port provides terminal management via a connected PC or another terminal device or modem. The terminal connected to the serial management port provides the same management functionality as Telnet interfaces (refer to chapter Telnet Connection).

If successfully connected, the prompt should appear as in the picture below.
Technical Description & Configuration Guide Configuration and Management Telnet Connection The Telnet connection to the LigoPTP 24 FODU is carried out using the Ethernet management connection. Please refer to chapter Assembling the Ethernet Cable Connector for Ethernet management port connection details.
Technical Description & Configuration Guide Configuration and Management After you have correctly entered the login and password, you are ready to work with all the available command prompt commands. Initial Configuration with Command Prompt Configuration steps using command prompt are as follows: Step 1. Check the system settings with command status Step 2.
Technical Description & Configuration Guide Status Window Status Window The main window in the Web GUI is the status window, which shows all the main system parameters, and, in case of failure or any other problem, it tints a specific parameter in red. To better understand what is exactly shown in the status window, we will go through every field of the status window. 1. Shows the name of this LigoPTP 24 FODU, its IP address, serial number and uptime since the last restart.
Technical Description & Configuration Guide Status Window LDPC is explained below in the chapter LDPC.
Technical Description & Configuration Guide Status Window Consume power – shows the amount of power consumed by PSU in watts (command line diagnostics). Tx polarization – shows transmission polarization and position of connectors and wires at the local side (command line - diagnostics). Radial MSE Radial MSE is a method for estimating the signal to noise ratio. ACM engine uses normalized MSE, which is the inverse of SNR.
Technical Description & Configuration Guide Detailed Configuration in Web Detailed Configuration in Web Configuration section in Web interface allows customizing your system to suit your specific needs. Main Configuration The main configuration window provides the configuration of most vital system parameters, including the ones in configuration wizard as well as some other important parameters. Below is a short explanation of provided customization fields.
Technical Description & Configuration Guide Detailed Configuration in Web ATPC Configuration To configure ATPC, it is necessary to set Rx (remote) “min” and “max” values and enable the ATPC feature. ATPC update period and ATPC delta are recommended to be left unchanged. It is also possible to change the limit of Tx power correction. Note, that ATPC is mechanism for reducing Tx power, that‟s why to make proper use of ATPC, transmitter power (Tx power) must be set to the maximum value.
Technical Description & Configuration Guide Detailed Configuration in Web ACM can be implemented together with automatic transmit power control (ATPC), complimentary features that enhance overall system performance. ATPC reduces the average transmitted power as well as CCI and adjacent-channel interference (ACI), which is caused by extraneous power from a signal in an adjacent channel.
Technical Description & Configuration Guide Detailed Configuration in Web Bandwidth – allows choosing between 7, 14 and 28 MHz bandwidths available. The default value is 7 MHz. This option is dependent on what bandwidth you have purchased. The wider bandwidth you have, the higher will be the overall link bitrate. The maximum bitrate of 108 Mbps is possible when using 28 MHz bandwidth (command line – modem bandwidth 7|14|28); Modulation – allows choosing between QPSK, 16APSK and 32APSK modulation.
Technical Description & Configuration Guide Detailed Configuration in Web Traffic can be mapped into different priorities, which define the level of service for each application. Figure 26 – ACM bandwidth capacity adaptation illustrates how different services – such as rich voice and video – are mapped into different classes of availability (CoA) such as 99.995% or 99.985%. The implementation of multiple priorities increases the available capacity up to 10 times that of standard links.
Technical Description & Configuration Guide Detailed Configuration in Web In comparison similar system using 32QAM and providing similar capacity would provide only 99,981% of availability. Besides, lack of ACM would not provide higher availability. You would have to decrease the distance, decrease modulation or increase antenna sizes to achieve 99,995% availability for the given link.
