Bytes in a frame structure used for the DCC channel in the optical regeneration section and bytes used for the DCC channel in the optical multiplexing section
Question: What are the bytes in a frame structure used for the DCC channel in the optical regeneration section? What are the bytes used for the DCC channel in the optical multiplexing section (OMS) to transmit network management information of a WDM system? Answer: According to SDH principles, bytes D1-D3 are used for the regeneration section, and bytes D4-D12 are used for the OMS section. In actual product application, however, bytes D1-D3 are used for DCC communication but bytes D4-D12 are not used.

What is Spatial Multiplexing
The MIMO technology provides the system with the spatial multiplexing gain and spatial diversity gain. In spatial multiplexing, multiple antennas are used on the received end and transmit end and multipath components in spatial communication is used, allowing signals to be transmitted over multiple data channels (MIMO sub-channels) in the same frequency band. This technology makes the channel capacity linearly increase with the growing number of antennas. This increase in channel capacity does not require additional bandwidth and does not consume additional transmit power. Therefore, spatial multiplexing is an efficient means to improve channel capacity and system capacity. In spatial multiplexing, serial-to-parallel conversion is performed on the transmitted signal to produce several parallel signal flows, which are then transmitted using their respective antennas in the same frequency band simultaneously. Due to the use of multipath propagation, each transmit antenna produces a unique spatial signal for the receive end. After the receive end receives the mixed signals of data, it differentiates these parallel data flows based on the fading between different spatial channels. Spatial multiplexing requires the spacing between transmit and receive antennas to be greater than the distance, ensuring that each sub-channel of the receive end is an independently fading channel.

After an IP phone is restarted, the phone time is restored to the factory settings.
If manually configured, the phone time will be restored to factory settings after the IP phone is restarted. If the phone time is obtained using NTP, it will not be restored to factory settings after the IP phone is restarted. To configure the NTP service, perform the following steps: 1. Log in to the phone's web page (http://IP address of the IP phone). The default user name and password are admin and admin123. 2. On the web page, choose System > Date and Time > Time server address 1 and set the address of the NTP server.
