Which of the following is the steps to multiplex a low-speed service into a high-speed SDH service? (Multiple choice).
If the overhead bytes pass through two plugged backplane buses, then the two slots are called paired slots that enable automatic transparent transfer of overhead bytes, such as (), () and (). Even if the SCC on the local network element The board is offline, which can also improve msP switching performance and protect DCC communication with other network elements. (Multi-quality selection).
Configuring the EPLAN service as a ring is not recommended. If the EPLAN service is configured as a ring network, the STP protocol must be enabled on the network to prevent broadcast storms.
