Descriptions : -
SUN-7211 is low cost bridging equipment, via a single E1 route to Ethernet. The interface is unframed mode E1 port with 2.048Mbps. Ethernet data bag occupy E1 frame 32 slot. The main E1 line can offer 2 kinds of clocks: The clock complex from E1 port and the equipment internal clock. The Ethernet interface using 10/100Base-T standard, full-duplex and half-duplex protocol support.
