Product Description
This model adopts inverse multiplexing technology that transmitting 1-4 10/100BaseTs or 10/100Base-FX Ethernet over 1-8E1 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
n Realize transparent transmission of Ethernet data over 1 to 8 E1 channels.
n Provide 4*100BaseTs Ethernet (or 100Base-FX Ethernet)
n Allow 8 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.
