APPARATUS FOR OPTICAL LINE TERMINAL AND APPARATUS FOR OPTICAL NETWORK TERMINAL

摘要

An optical line terminal and an optical network terminal for blocking optical transmission for malfunction and interception of optical transmission are provided to detect malfunction optical network terminal transmitting optical signal in PON environment and to secure the stability of PON(Passive Optical Network). A CPU checks a register(S500). The second number is recorded in the register(S505). The CPU confirms the counts of the registered optical network apparatus(S510). If the number of registered optical network units is not 0(S515), it confirms whether the number of registered optical network units are 1(S520). The CPU controls in order to transmit a second optical transmission intercepting message(S525). The CPU transmits a first optical transmitting blocking message to the registered each optical network terminal(S530). The register is checked in order to confirm that the failure is removed(S535).
