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

2 Chapter 2 Installation and Setup

This chapter describes installation and setup procedures for the standalone and card units.

NIC-EBS/L/V/i is delivered completely assembled. It is designed for tabletop or 19-inch rack installation.

After installing the unit, refer to

Chapter 3

to assure normal operation.

Internal settings, adjustment, maintenance, and repairs may be performed only by a skilled technician who is aware of the hazards involved.

Always observe standard safety precautions during installation, operation, and maintenance of this product.

2.1 Site Requirements and Prerequisites

An AC-powered NIC-EBS/L/V/i/AC should be installed within 1.5m (5 ft) of an easily accessible grounded AC outlet.

The outlet should furnish 100 VAC to 230 VAC.

A DC-powered NIC-EBS/L/V/i/DC unit requires -48/+24 VDC power source, which must be adequately isolated from the mains supply. In order to prevent a fire hazard, a suitable fuse should be installed in the VDC line.

Allow at least 90 cm (36 in) of frontal clearance for operating and maintenance accessibility. Allow at least 10 cm (4 in) clearance at the rear of the unit for signal lines and interface cables.

The ambient operating temperature of NIC-EBS/L/V/i is 0 to 50°C at relative humidity of 95%, non-condensing.

2.2 Configuration

This section describes how to configure NIC-EBS/L/V/i for a typical application.

The Figures and tables below illustrate the DIP switch location and provides details on the functions of the

NIC-EBS/L/V/i DIP switches, and their default settings.

Make sure that the power cord is disconnected before performing the DIP switch settings.

2.3.3 Connecting the Power

To connect the unit to the power source, refer to the appropriate section below, depending on your version of the unit.

This unit should always be grounded through the protective earth lead of the power cable.

2.3.3.1 AC Power Connection

AC power is supplied to the unit through the 1.5m (5 ft) standard power cable terminated by a standard 3-prong plug.

The cable is provided with the unit.

Before connecting AC power to this unit, the mains plug should only be inserted in a socket outlet provided with a protective earth contact. The protective action must not be negated by use of an extension cord (power cable) without a protective conductor (grounding). Interrupting the protective (grounding) conductor (inside or outside the unit), or disconnecting the protective earth terminal can make this unit dangerous.

●

To connect AC power:

1. Connect the power cable to the power socket on the rear panel.

2. Connect the power cable to the mains outlet.

3. Turn on the mains switch of the unit.

2.3.3.2 DC Power Connection

●

To connect DC power:

Certain DC-powered units are equipped with a plastic 3-screw terminal block located on the rear panel. Connect the wires of your power supply cable to the 3-screw terminal block, according to the voltage polarity and assembly instructions provided below.

¾ Preparing and Connecting the Power supply wires

1. Strip the insulation of your power supply wires according to the dimensions shown.

2. Place each wire lead into VDC-IN power input connector according to the voltage polarity mapping shown below (If a terminal is not already open, loosen its screw). Afterwards, tighten close the three terminal screws.

GND 0 -48V

Figure 2-6 DC power connection

Reversing the wire voltage polarity can cause damage to the unit!

Always connect a ground (earth) wire to VDC-IN power input connector Ground terminal. Connecting the unit without a protective ground, or interruption of the grounding (for example, by using an extension power cord without a grounding conductor) can cause harm to the unit or to the equipment connected to it!

3.2 Operating Procedure

3.2.1 Turning NIC-EBS/L/V/i On

NIC-EBS/L/V/i is turned on as soon as power is connected. When power is connected, the PWR indicator lights up and remains lit as long as NIC-EBS/L/V/i receives power.

NIC-EBS/L/V/i requires no operator attention once installed, with the exception of occasional monitoring of front panel indicators. Intervention is only required when NIC-EBS/L/V/i must be adapted to new operational requirements.

3.2.2 Normal Indications

If the local and remote NIC-EBS/L/V/i units are in operation and transmitting/receiving data, the following indicator conditions exist:

PWR: On

TD: Flashing or OFF

RD: Flashing or OFF

LINK: ON

LOS: OFF

AIS: OFF

SYNC: OFF

TEST: OFF

If the above LED indications are not obtained following initial power turn-on, check E1 or LAN interface connection.

3.2.3 Turning NIC-EBS/L/V/i Off

To turn off NIC-EBS/L/V/i, remove the power cord from the power source.

3.3 Loopback Test

This section contains procedures for performing system diagnostic tests for the unit. Use the test procedures provided in this section to:

¾ Verify normal system operation

¾ Isolate faulty equipment

¾ Identify other sources of system malfunction.

Tests are activated by the pushbuttons on the front panel and monitored via LED indicators. For description of the controls and indicators and their functionality, see the relative sections.

This product supports several types of loopbacks for evaluating the operation of the data system equipment and line circuits. Using these loopbacks, you can test communication between the attached equipment, internal circuitry of the local unit and remote unit.

Before testing the operation of the data system equipment and E1 link, ensure that all units are powered up and configured normally.

3.3.1 Local Analog Loopback (ANA)

The local analog loopback (ANA) test checks the performance of the local NIC-EBS/L/V/i unit, the local data terminal, and the connections between them. The test is performed separately at the local and the remote site. As shown in below, pressing the ANA pushbutton of unit A cause the unit A to loop its transmitter output back to its receiver for local device.

3.3.2 Local Digital Loopback (DIG)

The local digital loopback (DIG) test allows the operator at the remote end to check the performance of the local and remote unit, and their connecting lines. The DIG test loops the local unit, the received data back to the transmitter port for the remote unit. The local digital loopback test is equivalent to activating the remote loopback (REM) from the remote unit.

3.3.3 BER Test (L/R)

This unit has a built-in BERT circuit module consisting of a pattern generator and a pattern tester. This circuit works in conjunction with the V.54 diagnostic loops or the remote BERT to verify normal system operation and identify faulty equipment in the event of the system failure.

The pattern transmitted by the BER system of the local unit can be looped back for checking (unit self-test or single-unit test) or can be received by the remote unit (Two-BER test).

When testing together with the remote unit, the whole link between the local and remote units can be tested.

When the L/R button is pressed, BERT module continuously transmits the same 511-bit pattern to the E1 loop line and then receives the pattern to check. If the received pattern is right, the SYNC indicator will light up.

3.3.3.1 Unit Self-Test

The test verifies that the unit is operating correctly.

To activate the unit self-test:

1. Press the ANA pushbutton on the front panel. The TEST LED indicator lights up.

2. Press the L/R pushbutton.

If errors aren’t encountered, SYNC indicator will light up and LOS LED will be off.

3.3.3.2 Single-Unit Test

The test verifies that the unit and the E1 link are operating correctly.

To activate the single-unit test:

1. Make either a physical or logical loop on the E1 channel for the unit, or press the DIG pushbutton of unit B.

2. Press the L/R pushbutton of unit A. The TEST indicator of unit A lights up.

If errors aren’t encountered, SYNC LED of unit A will light up.
