2. Main features

In accordance with the provisions of IEEE 802.3, 802.3u Ethernet
ITU-T G.703, G.704 and G.823 protocols.

E1 interface framing/un-framing optional; balanced 120ohm
unbalanced 75ohm optional.

The E1 interface uses PCM31 mode, supporting CRC check.

E1 interface main/ slave clock optional in the framing mode.

In E1 framing mode, number of time slots is optional from 1 to 31.

Supporting 2.048Mbps transparent transmission in the E1
un-framing mode.

The two 100BASE-TX Ethernet interfaces support 100M half/ full
duplex modes.
 MAC addresses self-learning and addresses filtering functions,
reducing the transmission load of the E1 circuit.

Built-in 64Mbits SDRAM Ethernet data buffer memory, improving the
capability of Ethernet side anti-outburst, assuring high throughput of
data transmission.

E1 circuit local loop tests.

Pseudo random sequence test, facilitating the test of E1 circuit.
 Perfect circuit test and alarm indication.

Optional AC 220V or DC –48V input for bridge of both architectures
