1 Chapter 1 Introduction
1.1 Overview
NIC-EBS/L/V/i is a type of high quality Ethernet-to-E1 converter. As an extended equipment of Ethernet, it could be
used to connect two Ethernets transparently by PDH or SDH network and adapt to found remote network connection
with a low cost.
NIC-EBS/L/V/i has 1 10/100Base-T Ethernet interfaces with auto-negotiation function on Full/Half Duplex and
10/100M speed.
NIC-EBS/L/V/i can learn the MAC address automatically that be connected and transmit just the datagram with the
destination address in the remote Ethernet. So it can restrain the broadcast and advance the efficiency of the Ethernet.
The transmitting speed is up to 2.048Mbps.
Twin using of NIC-EBS/L/V/i at the application is suggested.
1.2 Versions
The following versions of the unit are available:
¾ NIC-EBS/L/V/i/AC: a standalone unit, AC power supply.
¾ NIC-EBS/L/V/i/48: a standalone unit, -48VDC power supply.
¾ NIC-EBS/L/V/i/24: a standalone unit, +24VDC power supply.
¾ NIC-EBS/L/V/i/C: a plug-in card unit consisting of a front sub card and a back sub card for installation in the
NIC-iRACK, 19-inch rack, holding up to 14 service cards.
