                E1 to Ethernet Protocol Converter (GFP)

                This model adopts inverse multiplexing technology that transmitting 10/100BaseTs or 10/100Base-FX Ethernet over 1 E1 link. Employing Ethernet-over-PDH technique, it allows the transport of native Ethernet frames over the well-established PDH telecommunications infrastructure. This enables carriers to make use of the extensive legacy PDH and TDM equipment to provide new Ethernet-centric services. It supports flexible configuration if 1 E1 links, auto-detecting the number of E1 and selecting the available channels. It allows certain delay between the E1 link. The rate of one link is 1980kbps, and 7920kbps for 4 links.
