The UMG is designed based on the softswitch architecture.

The UMG considers both the factors in design. The board deployment in an SSM 32 frame is shown in Figure 3 The redundancy and error tolerance designs are adopted.
Multiple CPUs comprise a cluster processing system and each module has distinct functions. The UMG offers a powerful software upgrade tool. One MGW can be divided physically or logically based on the capacity, functions and performance instead of belonging to the MSC Server simply. Based on the basic requirements of reliability design, this chapter describes some designs and applications of the UMG in the respect of reliability.
The UMG also employs the independent operational and management policy. They are used to exchange H. Clock subboards can be attached to the MTNC boards in the main control frame to provide stratum 3 clock signals or independent CLK boards can be configured to provide stratum 2 or stratum 3 clock signals.
It can cooperate with the softswitch to meet core switching applications at different network phases. Improves the error tolerance ability of software based on different tasks or mechanism Fault Monitoring and Handling: In detail, it profiles the logical interfaces, hardware and software components of the UMG The UMG has the following mechanisms for fault monitoring and handling. Reminder To have a better experience, please upgrade your IE browser.
As standardized hjawei are used, there is no requirement for special tools in equipment mounting. Radio Access Network Devices. Some measures are taken to prevent rain hyawei into the packing box. If you are interested in Huawei products, solutions or services, please let us know how we can help you by submitting your requirements and background information.
Universal Media Gateway UMG — Huawei products
The UMG also provides auxiliary functions such as the management and maintenance of the device, the clock and cascading functions. Common slots are for service processing boards.
These indexes are explained as follows: The UMG frames can be logically classified into the main control frame and service frame. For details about board configuration, see the online help for MML commands. If the master board fails, the slave one becomes active to ensure the normal running of the system.
The interfaces provided by the UMG comply with relevant specifications. AR Series Enterprise Routers. The LMT system consists of four parts: The CLK boards shall be inserted in back slots 0 and 1 in the main control frame.
The network evolves toward a flattened architecture and the networking is more flexible. The central switching frame uses an SSM frame. Thus, you can protect your investment to the most extent. That is, the RTP packet is compressed, the bandwidth occupied by the RTP packet is reduced, and the transmission efficiency is improved.
In the TrFO mode, the end to end negotiation is completed at the control plane before a call connection is set up. Help Center Find new research papers in: Thus, the system can prevent attackers from finding system holes through the port scanning technique.
The UMG is placed in an area of dense hawei. There is no requirement for independent cascading boards. Service frames use frame Nos. Through the configuration of command groups and users, the system can effectively implement hierarchical management of operators and operation nuawei.
The CHRs are saved on the server for value added applications such as real time monitor and troubleshooting.
In this case, you need to configure independent cascading boards, that is, NLUs. The MBus system umg900 independent of higher layer software. The above information can be stored for fault locating and fixing purpose. Change password No account?
