Huawei UMG (Universal Media Gateway) | TXO Systems

The central switching frame provides switching and cascading functions. The service frame provides the service processing function.

The control frame only processes call control messages rather than carry services. In addition, clock distribution cables are connected from the CLKs in the main control frame to the service frames and central switching frame to provide clock signals for the service frames and central switching frame.

The main control frame is always numbered 1. The main control frame can also serve as the central switching frame at the same time.

No independent cascading boards are required. In this huaei, you need to configure independent cascading boards, that is, NLUs. Clock subboards can be installed on the TNCs in the main control frame to provide stratum-3 clock signals, or independent CLKs can be configured to provide stratum-2A or stratum-3 clock signals.

Other frames extract clock signals through the TDM cascading cables between frames. No independent clock distribution cables are required. The main control frame is always numbered 1 and the central huawwi frame is always numbered 0. In this mode, the SSM main control frame can use the clock subboard on the TNC to provide stratum-3 clock signals or use the CLK to provide stratum-2 or huawel clock signals.

The SSM central switching frame and the SSM service frame use clock distribution cables to extract clock signals.
