The EM6T/EM6F is an FE/GE interface board, which provides four FE electrical ports and two GE ports. The EM6T/EM6TA has similar functions to the EM6F/ EM6FA. The only difference is as follows: The GE ports on the EM6T/EM6TA use fixed electrical ports whereas the GE ports on the EM6F/EM6FA use the SFP modules and therefore can function as two FE/GE optical or GE electrical ports. The GE electrical ports on the EM6F/EM6FA and the EM6T/EM6TA are compatible with the FE electrical ports.
1- Receives/Transmits FE/GE service signals and works with the packet switching unit to process the received FE/GE service signals.
2- FE electrical port provides four 10/100BASE-T(X) ports.
3- GE port Provides two10/100/1000BASE-T(X) ports (unpluggable).
4- Backplane bus bandwidth 1 Gbit/s
5- Supported LAG & ERPS & IGMP snooping & LPT & Port mirroring & LLDP & RMON.
6- InbandDCN Each FE/GE port provides one inbandDCN channel.
7- Supports the following loopback types: l Inloopsat the PHY layer of Ethernet ports l Inloopsat the MAC layer of Ethernet ports.
8- l Supports IEEE 802.1ag-compliant ETH-OAM function. l Supports packet loss, delay, and delay variation measurement functions that comply with ITU-T Y. 1731.
