FE1&10/100BASE-T Interface Converter (also as FE1&10/100BASE-T Ethernet Bridge) is an Ethernet bridge of high performance, which accomplishes the convertering between the 100M Ethernet port and the E1 port. As an extended device of the Ethernet, the FE1&10/100BASE-T bridge realizes interconnection of two Ethernet by using the E1 channel provided by existing networks with low cost.
Feature for Product:

1.In accordance with the provisions of IEEE 802.3, 802.3u Ethernet, ITU-T G.703, G.704 and G.823 protocols
2.E1 interface framing/unframing optional; balanced 120ohm
3.Unbalanced 75ohm optional
4.E1 interface uses PCM31 mode, supporting CRC check.
5.E1 interface main/ slave clock optional in the framing mode.
6.In the E1 framing mode, the number of time slots is optional from 1 to 31
7.Supporting 2.048Mbps transparent transmission in the E1 unframing mode
8.Supports 10/100M half/ full duplex modes
9.MAC address self-learning and address filtering functions, reducing the transmission load of the E1 circuit
10.Built-in 64Mbits SDRAM Ethernet data buffer memory, improving the capability of Ethernet side 11.anti-outburst, assuring high throughput of data transmission
12.E1 circuit remote loop and local loop tests
13.Pseudo random sequence test, facilitating the test of E1 circuit
14.Perfect circuit test and alarm indication
15.Two architectures: stand alone and 19in rack mount architecture (16 interface converter modules can be inserted in the rack mount architecture)
16.Optional AC 220V or DC -48V input for bridge of both architectures
17.Hot rearup of double power supplies is provided for the bridge of rack mount architecture, assuring high reliability
