The OLT (Optical Line Terminal) network element is an important part of the passive optical network. It consists of multiple boards. Each board supports multiple PON ports. The PON port is the port of the OLT. Each PON port has only one channel, and the channel is used for data transmission between an optical network unit (ONU) and an OLT network element.

For example, an ONU configured in a GPON mode needs to find a configuration mode and also a GPON PON port access. However, in the actual application, the configuration mode of the ONU may change. For example, if the user is adjusted to the configuration mode of the XG-PON1 by the ONU of the GPON configuration mode, the original GPON mode PON port cannot be compared with the adjusted ONU. compatible.

The configuration mode supported by the multiple channels that are obtained in advance may be: when configuring multiple channels of the PON port, recording and storing the configuration mode supported by each channel; or After the channel, the configuration mode supported by the channel is obtained by detecting the attributes of each channel; or after the multiple channels of the PON port are configured, the operation input by the user is received to record and store the configuration modes supported by each channel. For example, the configuration mode of channel 1 is GPON, and the configuration mode of channel 2 is XGS-PON, etc., so that the optical network unit can access the channel that is consistent with its configuration mode. The configuration mode is the optical network unit of the GPON. When the channel selection is performed, the configuration mode is also selected for the GPON channel and the optical network unit for data transmission; if the configuration mode of the optical network unit is upgraded by GPON To a later version, the configuration mode of the channel is changed accordingly.
