Abstract

Systems, devices and techniques for automatically configuring a Demarcation device in a communication network based on DOCSIS provisioning over EPON. A method can be implemented to include initializing a Demarcation device and an optical network unit device (ONU) that is connected to the Demarcation device; operating the Demarcation device to establish a communication with the ONU and to obtain configuration information of the ONU; operating the Demarcation device to communicate to a back-office system in the network regarding information of the Demarcation device, the information including capabilities associated with the Demarcation device; operating the back-office system to generate a service configuration file and to send the generated service configuration file to the Demarcation device; and operating the Demarcation device to process the service configuration file from the back-office system and to update communication services provided by the ONU based on the service configuration file from the back-office system.

Claims

1. A method for providing auto configuration of a Demarcation device in a communication network based on Data Over Cable Service Interface Specification (DOCSIS) provisioning over Ethernet Passive Optical Network (EPON), comprising:

initializing the Demarcation device and an optical network unit device connected to the Demarcation device;

performing, by the Demarcation device, port configuration to allow communication to the optical network unit device, wherein the communication comprises forwarding frames from the Demarcation device to the optical network unit;

establishing, by the Demarcation device, a communication with the optical network unit device and obtaining configuration information of the optical network unit device;

communicating, by the Demarcation device, to a back-office system in the network, information regarding the Demarcation device , the information including capabilities associated with the Demarcation device;

receiving, at the Demarcation device, the service configuration file from the back-office system, wherein a timer, implemented at the Demarcation device, restarts the Demarcation device when the service configuration file is not received prior to expiration of the timer and after the timer restarts the Demarcation device for a predetermined number of times, the predetermined number of times defined in the service configuration file, the Demarcation device powers down and awaits user intervention; and

processing, at the Demarcation device, the service configuration file received from the back-office system and automatically updating communication services provided by the optical network unit device based on the service configuration file received from the back-office system.

2. The method as in claim 1, wherein:

the communication established between the Demarcation device and the optical network unit device is based on IEEE 802.1AB Link Layer Discovery Protocol (LLDP) protocol with the DOCSIS Provisioning over EPON specific type-length-value (TLV) values.

3. The method as in claim 1, comprising:

utilizing, by the Demarcation device, Dynamic Host Configuration Protocol (DHCP) to communicate with the back-office system.

4. The method as in claim 1, comprising:
