The memory (210) of the optical line terminal (OLT) (110) of a broadband passive optical network (BPON) (200) is increased to store, in addition to an active identity number, such as the serial number, of the current optical network terminal (ONT) connected to a network end point (EP), a standby identity number, such as the serial number, of a replacement optical network terminal (ONT) when upgrades are requested by the end users, or partial or total failures are reported by the end users. |
