      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.

      Description

      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.

      Features

      n Realize transparent transmission of Ethernet data over 1 E1 channel. 

      n Provide 100BaseTs Ethernet (or 100Base-FX Ethernet)

      n Allow 1 E1 channels up to 220ms transmission delay. When the delay exceeds allowed limit range, it can stop transmitting data automatically. 

      n Supports Dynamic Ethernet MAC address (4096) with local address filter function.

      n Has 2 loop back functions: E1 local loop, E1 remote loop.

      n E1 interface compatible with ITU-T G.703, and G.823. not supporting signal timeslot.

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

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

      n E1 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.

      n Supports resetting remote system from local system.

      n Support Console management and WEB management.
