Product Description

Product: E1-10/100BASE-T Bridge
Model: NE-2701, NE-2702
Product Overview

The design of NE-2701 Ethernet-E1 converter adopts the ASIC chip as the core, which features simple circuits and compact structure and enhances the reliability of the integrated equipment. As an extended device of the Ethernet, the FE1/100BASE-TX bridge realizes interconnection of two Ethernet by using the E1 channel provided by existing networks with low cost. the E1 channel provides a rate of 2.048Mbps and accomplishes transparent transmission.

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 the E1 framing mode, the number of time slots is optional from 1 to 31.
         Supporting 2.048Mbps transparent transmission in the E1 un-framing mode.
         The 100BASE-TX Ethernet interface supports 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 remote loop and local loop tests.
         Pseudo random sequence test, facilitating the test of E1 circuit.
         Perfect circuit test and alarm indication.
         Two architectures: stand alone and 19in rack mount architecture (15 interface converter modular and one NMS modules or 16 interface converter modules can be inserted in the rack mount architecture) ;
         Optional AC 220V or DC –48V input for bridge of both architectures
Hot rear up of double power supplies is provided for
         the Bridge of rack mount architecture, assuring high reliability.
         Support local Hypber Terminal management via RS232 serial port and remoter management by Telnet、Web、SNMP and CGI management software.
         Can be communicate with the bridge of other company.
