Telecommunications access systems implementation method is described in detail.
Electric power terminal multi-service telecommunications access systems implementation method provided by the invention based on timeslice isolation includes pressing
The following steps that sequence executes：
Step 1) builds communication system：
Build the communication system based on EPON networks, typical EPON system optical link full guard operating mode such as Fig. 1
Shown, the communication system includes：Optical line terminal (OLT) 1, Optical Distribution Network (ODN) 2 and multiple optical network units
(ONU) 3, wherein：Optical line terminal 1 is connect by Optical Distribution Network 2 with multiple optical network units 3；
The optical line terminal 1 is arranged in substation or cell switchgear house, passes through Optical Distribution Network 2 and each power distribution station
Interior optical network unit 3 connects.
For optical line terminal 1 when carrying out signal processing, internal production control great Qu Service Processing Modules only handle life
The business information of production control great Qu, management information great Qu Service Processing Modules only handle the business information of management information great Qu.It is raw
Production control great Qu Service Processing Modules and management information great Qu Service Processing Modules pass through respective Ethernet interface and electric power bone
Dry communication network connection, realizes that data upload.
The optical network unit 3 is arranged in power business terminal equipment side, passes through Optical Distribution Network 2 and optical line terminal
1 is connected, and realizes the access of electric power terminal communication service.
Optical network unit 3 is connected by Ethernet interface with power business terminal device；It is different to ensure the isolation of business
Different from the optical network unit 3 Ethernet interface connections respectively of the terminal device of safe great Qu.It is raw inside optical network unit 3
The production control great Qu Service Processing Modules only business information of process for producing control great Qu, management information great Qu Service Processing Modules are only
Handle the business information of management information great Qu.
The Optical Distribution Network 2 is made of the optical cable laid with supply line's same period, and optical link is used on operating mode
Full guard operating mode or hand in hand protection operating mode, can also be used unprotect pattern.
