Description of functions
ON-9864 is a new generation SDH multiplexer for transmitting TDM traffic and Ethernet traffic with L2 processing, designed for integration into modern multiservice networks. In the maximum configuration of optical boards, it can support up to 10 SDH fiber rings of different STM levels (STM-64/16/4/1) with SNCP, MS-SPring or MSP 1+1 protection. It supports up to 4 STM-64 optical ports (on two DXC boards), up to 12 STM-16 optical ports (4 optical ports on two DXC boards and 8 optical ports on optical boards in slots 1 and 2) and up to 16 STM-4/1 optical ports (4 optical boards in slots 1-4). In the maximum configuration of the E1 cards, it supports up to 240 E1 ports, and in the maximum configuration of the Ethernet cards, it supports up to 24*10/100/1000 Mbps copper Ethernet ports in the corresponding slots. Users can make any combination of tributary boards according to the requirements of their network. The optical interface complies with ITU-T G.655, 652, and G.653 international communication standards. All modules can be replaced if necessary without interrupting traffic.
ON-9864 provides two interfaces for hardware management. The first way of management is through the Web server interface. Users can manage their network segment via Web browsers. The second control method is via the SNMP protocol, which is a standard UDP–based network management protocol.
ON-9864 ensures the security of the administration of the management system. The administrator can set user accounts and passwords to deny access to those users who are not allowed access to the network.
ON-9864 issues emergency SNMP messages to any message system operating under the SNMP protocol, and also writes them to the logs of current accidents and the history of accidents with a maximum capacity of 9999 records, which makes it easy to identify and fix the problem.
The alarms of the ON-9864 multiplexer are divided into 3 levels according to the degree of importance: critical, important and insignificant. The user can independently set the degree of criticality of the ON-9864 alarm signals using the Web interface. All multiplexer alarms are sent to the user via the user control interface.
In addition to the Crash Signal report, ON-9864 performs Performance Monitoring (PM) to control transmission quality on optical and electrical interfaces. Users can collect and analyze data to evaluate the transmission quality. All parameters can be read and processed through management interfaces.
The protection of the optical interface is important for the optical transmission system. ON-9864 allows you to provide 1 + 1 protection for all working optical modules in a point-to-point topology. The multiplexer switches traffic from the working line to the backup line automatically in case of signal loss (LOS) or large errors on the working line. Users can also switch the optical line manually using the Web interface. For ring topology, MS-SPring or SNCP at the VC-4/3/12 level are used for protection.
Synchronization is important for transmission quality in synchronous optical networks. In ON-9864, it is carried out by a digital phase-locked frequency (PLL) system, which provides synchronization of the internal generator of the multiplexer with the selected synchronization source. This ensures the quality of traffic transmission in SDH networks.
To diagnose emerging accidents, ON-9864 can use two functions: test loops and test sequence. To debug and identify transmission problems in the network, there are these functions, they can be enabled via the Web interface. ON-9864 can send a test sequence for each E1 channel and calculate the error rate.
The ON-9864 is easily mounted in standard 19” or 23” (ETSI) racks. The multiplexer complies with the standards of overvoltage protection in accordance with IEC-61000-4-5 Class 3 and FCC Part 68 and ITU-T K.20, K.21 standards for E1 interfaces and AC and DC power supplies.
The FG-FOM-MS64 has two DC boards, providing 1+1 redundancy for the cross-connection matrix, internal generator and system controller.
