Example configuration methods and apparatus are described. In one example method, a first baseband unit (BBU) updates a first line rate, and sends a data frame to the second BBU at an updated first line rate after each update. The first BBU receives a data frame that is sent by the second BBU at an updated second line rate after each time the second BBU updates a second line rate. When the first line rate is equal to the second line rate, the first BBU sends networking relationship information of the first BBU to the second BBU at the first line rate, and receives networking relationship information of the second BBU that is sent by the second BBU at the second line rate. The first BBU establishes a bidirectional upper-layer communication channel with the second BBU based on a communication address of the second BBU allocated by the first BBU.

Integrated access system, configuration method, and baseband unit

Provided are methods, systems, and apparatus related to a gas detector () and a gas detector calibration cap (). The gas detector calibration cap includes a cap body (), a first cap wing (), a second cap wing (), and an extended strip () for opening the gas detector by inserting the extended strip in a groove () of the gas detector. The extended strip allows a worker to easily open the gas detector housing, thus improving the speed and reliability of servicing the gas detector while eliminating the potential additional cost on a separated tool for opening the gas detector housing.

The present invention discloses a communication signal multiplexing method, a radio communication system, and a radio equipment controller (REC). Taking the common public radio interface (CPRI) standard as an example, by carrying multiple CPRI links on limited physical links (CPRI-MUX), generally one high-speed physical link, physical bandwidth is used more efficiently and the number of interconnected interfaces and the system cost are reduced without compromising with the CPRI standard is maintained. When the bandwidth provided by the high-speed physical link is insufficient, more physical links can be adopted.
