(INUe Intelligent Node Unit Extended)


Description of INUe Cards• NCC ( Network Controller Card) : It provides the key node management

and carries the main power supply for -48 V DC input. It also contains the Flash card( 256 MB) which holds the management software.


RAC ( Radio Access Card) :

It connects to ODU via 50 ohms coaxial cable. RAC sends data on to optical port.

These are two types of RAC cards: RAC 30V ( non XPIC links) RAC 40V (XPIC links)


DAC( Digital Access Card) :

This card has optical Fiber interface. This Fiber interface sends its data to multiplexer.

DAC cards are of two types: 1. 1 X 155o DAC 2. 2X 155o DAC Fan Unit : For cooling of INUe.


Some Installation Sites of INUe in SDH Ring:

•2-STM1 Ring Hub site

• 2 STM1 Ring Node


9500 MXC CT Software Introduction

IDU/INUe both are monitored through same software.

Performance

For a RAC the Performance screen provides G.826 data for the selected link, plus Tx power, RSL, PA temperature, -48Vdc supply voltage at the ODU, and an estimate of current BER and remote fade margin (fade margin at the far-end Rx).

G.826 data includes: • Elapsed, available and unavailable seconds • Errored seconds and errored second ratio • Severely errored seconds, and ratio • Block error, background block errors, and ratio How to see Performance (RSL)? Diagnostics Performance

System Controls•This is very important feature of 9500 MXC. Why?


System Controls contd.

Warning will be appeared on RAC with alarm description demodulator locked.


History

The History screens provide either a seven day, or one month graphical and report views of operational history, captured as 15 minute data bins over the most recent seven days, or daily bins over one month.

For links the screen supports G.826 data, RSL, events, and configuration changes, errors, events and configuration changes.

We have two formats of history are available: 1- Graphical view 2-Report View How to see History? Diagnostics History

Event Browser The Events Browser screen provides a time and date-stamped view of

the most recent 5000 events, both active and cleared. Options include viewing of current alarms only, or all occurrences of a selected alarm type.

For each alarm or informational event a tab provides access to additional information. For alarms the alarm description, probable causes, and recommended actions are displayed. For information events its description is displayed.

Parts• The parts screen presents:

1. Part Number

2. Part Revision

3. Serial Number

4. Time in service


Current Alarms

An alarms screen provides a tree-view of all alarm actions for a selected plug-in. For each alarm a tab provides access to the alarm description, probable causes, and recommended actions.

Problem Icons


Alarms on IDU 9500 MXC (SEEN ON SYSTEM SUMMARY)

CASE 1: In system summary, RAC is red. Alarm appears will be Errored second ratio (ESR) + Errored second + Alarm Indication

Signal. ODU LED will glow red on IDU front panel.

Probable Cause:

ODU is faulty or surge arrestor is faulty.


Alarms on IDU 9500 MXC (SEEN ON SYSTEM SUMMARY) contd.

CASE 2:In system summary, DAC is red. Alarm appears will be Loss of Frame

(LOF) or tributary loss.Probable Cause:

DAC card is faulty or fiber is faulty.CASE 3:

In system summary, IDU icon is showing warning.IDU LED will start flashing on front panel.

Probable Cause:

IDU is synchronization with NMS server or software of main/stdby IDU is different.


Alarms (SEEN ON EVENT BROWSER)ALARM 1:

Alarm Indication Signal (AIS) + Loss of Frame (LOF)Probable Cause:

DAC card is faulty or Fiber is unplugged or Fiber is faulty. In system summary, DAC card will be red. ALARM 2:

ESR threshold exceeded Probable Cause:

Interference, equipment malfunctioning or Path Condition If ESR threshold exceeded at local end and RSL is OK, it means that

interference at from another link.ESR ---> demodulator not locked ---> Traffic Path Down (Path Failure)--->

Path Warning (complete path fading or Remote Tx faulty i.e. ODU),


Alarms (SEEN ON EVENT BROWSER)

ALARM 3: 10 E-3/10 E-6 threshold exceeded

Probable Cause:

Interference at both ends. In system summary RAC card will show warning alarm on both ends.


9500 MXC CT installation at LAPTOP
