【Functional description】
3.1 Time synchronization based on 1PPS+TOD mode: The base station can support the input of the 1PPS signal and the TOD information to obtain synchronization timing information, so that the base station and the upstream time of the transmission network can realize the air interface time and frequency precision.
3.2 Digital compatibility: It is compatible with the latest models of mainstream BBU equipment from Huawei, ZTE, Ericsson, Nokia, etc. (the device needs to have HDMI interface).
3.3 Connection BBU indication function: GPS signal room intelligent multi-channel distribution system device signal output terminal is connected to the GPS signal input end of BBU. After the GPS input end of BBU is connected to the clock synchronization system device output end, the clock synchronization system device should have access status indication.
3.4 Alarm function: After the RGS108D is connected to the host device (iRGS208), the 8 output ports of the RGS108D are connected to the corresponding GPS receiving device or BBU. The access port of the receiving device has 5V DC power. At this time, the corresponding port indicator will be lit red. Start. Pressing the reset button will clear the alarm of the dry node and memorize the connection status. If the device of the RGS108D output port is disconnected or the new device is connected, the dry node will have an alarm.
When the alarm is triggered, the status can be cleared and memorized again by pressing the reset button.
