Overview
ZTE C220 central office EPON service board, each board provides a maximum of 4 EPON interfaces, mainly completes the related functions of the OLT side in the EPON system, supports docking with various companies' PON ONUs, and can meet the requirements of CTC interoperability testing.
The specific functions that can be achieved are as follows:
1. Each EPFC single board supports 4 EPON OLT ports, each with a downstream rate of 1.25Gbps;
2. Support 802.3ah standard multipoint control protocol (MPCP), OAM and other functions;
3. Support ONU dynamic discovery, automatic registration and dynamic ranging;
4. Complete the perfect DBA function;
5. Support IGMP snooping, each PON supports 256 multicast groups; Single board has MPU system, providing complete single board OAM function;
6. A single PON port supports at least 32 branches and a maximum of 64 branches.
