EG4P

EG4boards are 4xGE interface boards, which provide flexible combinations of port types to meet a wide variety of service requirements. One EG4/EG4P board provides a maximum of four ports, two always being RJ45 electrical ports and the other two being small form-factor pluggable (SFP) ports or RJ45 electrical ports. On an EG4P board, the two fixed RJ45 electrical ports provide the RTN 300 full-outdoor radio equipment series with power and service signals simultaneously.
Functions
1- Receives/Transmits GE service signals, and processes these signals by working with the packet switching unit.
2- Provides four GE ports. l Provides two unpluggableGE electrical ports (through which EG4P boards support power over ethernet). l Provides two unpluggable GE electrical ports or two SFP optical ports. Supports the following types of SFP modules: – Dual-fiber bidirectional FE/GE optical module – Single-fiber bidirectional FE/GE module
3- Backplane bus bandwidth l 1 Gbit/s when an EG4/EG4P board works with an SL91CSH board l 2.5 Gbit/s when an EG4/EG4P board works with an SL92CSH/ CSHU/CSHUA board .
4- Supported LAG & Spanning Tree Protocol (STP)  & IGMP snooping & Link-state pass through (LPT) & Port mirroring & LLDP & Anti-Theft function
