The invention discloses a system and method for cascading sub-frames of a PON access system, and relates to the field of PON access systems. In the system, both the system sub-frame and the extended sub-frame include a cascading management module, a device management module and a master-slave Communication module: the cascading management module is used to initialize, delete or maintain the cascading state between the system sub-box and the extended sub-box; the device management module is used to complete the configuration of the cascading port and the configuration of the data path between the system sub-box and the extended sub-box Open up; the master-slave communication module is used to assign MAC addresses and IPs to the service disks of the extension sub-frame according to the cascading status between the system sub-frame and the extension sub-frame, and to establish a master-slave connection between the system sub-frame and the extension sub-frame; The system sub-frame also includes a database, and the database is used to save configuration data, and the configuration data includes sub-frame roles, cascading sub-frame numbers and cascading ports. The present invention can flexibly configure the number of cascaded sub-frames according to the number of users to meet the requirements of different regions and different operators.
Description
technical field [0001] The invention relates to the field of PON (Passive Optical Network) access systems, in particular to a system and method for cascading sub-frames of the PON access system. Background technique [0002] OLT (Optical Line Terminal, Optical Line Terminal) is a large central office integrated service access device, mainly serving major domestic telecom operators and private network users, as well as telecom operators in the international market. [0003] OLT supports PON, MSAN (Multi-Service Access Network, integrated service access network) hybrid networking, or PON, MSAN separate networking. In the MSAN single networking mode, the current operator proposes that a single rack should support 1536 DSL (Digital Subscriber Line, Digital Subscriber Line) users or 1536 POTS (Plain Old Telephone Service, Analog telephone service) users, the market also urgently needs a single rack device (including expansion sub-frame) to access no less than 1536 DSL / POTS users...
