Features:

 

2       in accordance with the provisions of IEEE 802.3u,IEEE 802.1q,IEEE 802.3x,ITU-T G.703,G.704 and G.823 protocols.

2       E1 interface support framed and unframed mode;

2       E1 support balanced 120ohm(RJ45 conncetor) and unbalanced 75ohm(BNC connector).

2       the E1 interface uses PCM31 mode, supporting CRC check.

2       E1 interface main/slave clock optional in the framing mode.

2       Supporting 2.048Mbps transparent transmission in the E1 unframing mode.

2       the 10/100Base-T Ethernet interface supports 10/100M half/full duplex modes.

2       Ethernet port support isolation based on port and tag VLAN (16 VLAN).

2       the rate of each Ethernet port is measured by the configuration software, bandwidth particles for 32 k.

2       Each Ethernet port support broadcast storm protection, PAUSE flow control.

2       MAC address self-learning and address filtering functions, reducing the transmission load of the E1 circuit.

2       Built-in 64Mbits SDRAM Ethernet data buffer memory, improving the capability of Ethernet side anti-outburst, assuring high throughput of data transmission.

2       E1 circuit remote loop and local loop tests.

2       Perfect circuit test and alarm indication.

2        Support local console network, can be set up on the Ethernet port.
