    摘要: An apparatus or corresponding method of managing Plain Old Telephone Service (POTS) lines in a Passive Optical Network (PON) to prevent an alarm system from generating an alarm during a software upgrade or maintenance of an Optical Network Terminal (ONT), Optical Line Terminal (OLT), or PON while maintaining the effectiveness of the alarm system. The ONT may store data related to a POTS line in nonvolatile memory. The ONT may activate the POTS line based on the data from the nonvolatile memory in an event of interruption in communications with an OLT prior to reestablishing communications with the OLT. The interruption in communications may be caused by an ONT reboot to complete an installation of a software upgrade. The ONT may energize the POTS line with a voltage in response to activating the POTS line to prevent the alarm system from generating the alarm.

    摘要: When an optical network terminal (ONT) is rebooted, for example, after being upgraded, the ONT may be not be ranged and provisioned for some time. This may disrupt services, such as video services provided to a customer. As such, a method and corresponding apparatus of ensuring continuous receipt of video services based on certain conditions in a passive optical network (PON) are provided. The method may include detecting at a PON element a condition indicating a change of states in receipt of video services, starting a timing mechanism having a default value stored in the PON element, and enabling receipt of video services at the PON element for an amount of time defined by the default value. Receipt of video services is enabled by maintaining a configuration for video services previously provisioned and re-provisioning the PON element with the maintained configuration. In this way, disruption to video services is reduced.

    摘要: A method of ensuring continuous receipt of video services based on certain conditions in a passive optical network (PON) is provided. The method includes (i) detecting at a PON element a condition indicating a change of states in receipt of video services, (ii) starting a timing mechanism having a default value stored in the PON element, and (iii) enabling receipt of video services at the PON element for an amount of time defined by the default value. The receipt of video services may be disabled after the amount of time defined by the default value.

    摘要: A video overlay system for a Fiber to the Premises (FTTP) optical network. The video overlay is achieved by including a video router with a gigabit Ethernet interface including Internet Group Management Protocol (IGMP) multicasting capability in a headend. The video router transmits unidirectional Internet Protocol video to a plurality of Single Family Unit (SFU) Optical Network Terminations (ONTs) at 1550 nm. The SFU ONTs include IGMP snooping (MxU ONT with multicasting) capability and carry bi-directional control signals from Set Top Boxes (STBs) using 1490 nm downstream and 1310 nm upstream traffic to the headend via an Optical Line Termination (OLT).
