Overview
MEL-202, the 2E1&10/100Base-TX Bridge is a device that takes ASIC chip as its core and enables Ethernet data to be transmitted through multi 2E1 channels. The Bridge breaks through the bandwidth limit of single E1 Ethernet bridge. It is very easy to make use of the existing rich E1 resources in the public networks to quickly extend the range of the Ethernet LAN. The MEL-202 Bridge is an enhancement model of the Ethernet to multi E1 converter.
Features
● Support 2E1 bandwidth, 75ohm or 120 ohm optional ● In accordance with G.703, G.736, G.823, IEEE802.3u standard.
● Provide 2*10/100M Base-T ports, support 10/100M full duplex and half duplex, and support auto-negotiation mechanism
● Ethernet interface 10/100M、full/half duplex modes auto-negotiation
● Architectures: stand alone, modular
● Optional AC 220V or DC –48V input for bridge of both architectures
