                16E1 to 4Ethernet Protocol Converter

                This model adopts inverse multiplexing technology that transmitting 1-4 10/100BaseTs or 10/100Base-FX Ethernet over 1~16 E1 links. 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 1~8E1 links, auto-detecting the number of E1 and selecting the available channels. It allows certain delay between the multi-E1 links. The rate of one link is 1980kbps, and 7920kbps for 8 links.

                Product Description

                This model adopts inverse multiplexing technology that transmitting 1-410/100BaseTs or 10/100Base-FX Ethernet over 1-16E1 links. 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 1~8E1 links, auto-detecting the number of E1 and selecting the available channels. It allows certain delay between the multi-E1 links. The rate of one link is 1980kbps, and 7920kbps for 8 links.

                Features

                nRealize transparent transmission of Ethernet data over 1 to 16E1 channels

                nProvide 4*100BaseTs Ethernet or 100Base-FX Ethernet

                nAllow 16E1 channels up to 220ms transmission delay. When the delay exceeds allowed limit range, it can stop

                transmitting data automatically 

                nSupports Dynamic Ethernet MAC address (4096) with local address filter function

                nHas 2 loop back functions: E1 local loop, E1 remote loop

                nE1 interface compatible with ITU-T G.703, and G.823. not supporting signal timeslot

                nCLK mode: support internal CLK mode and E1 line CLK mode. E1 line CLK realizes auto-switch over the E1 line  according the signal quality

                nCompatible with ITU-T protocol: G.7041 (GFP-F) , G.7042 (VCAT, LCAS), G.7043, G.8040

                nE1 loop detecting: if any channel of E1 loop detected, it will cut off the channel. And after the loop released, the channel will be renewal

                nSupports resetting remote system from local system

                nSupport Console management
