NEAX 61E

After long time,due to Busy life I was unable to write you.
in this time I am going to say about OLD great thing.

I was able to touch a Very OLD Telephone exchange called NEAX61E.
this was a great system in the history and many countries ware powered by this NEAX61E system.
it was a great creation of NEC company in JAPAN.though it is a old system I believe many 3rd world countries are using this system yet and this article will remind your memory if you have worked with this system in your life.
so I thought to put some switching commands to recall your memory.

1.Display

DSP:

2.Display system status

DSP:SOS;

3.To Reconnect

SOD:SPR,N=number; (number must without area code)

4.To Disconnect Out oing Calls

SOD:SPS,N=number,,ORG;

5.To Disconnect All Calls (TOS)

SOD:SPS,N=number,,ALL;

6.Call Baring (ALL)

SOD:CLC,N=number,,,RC=101;

7.To add IDD Facility

SOD:CLC,N=number,,,RC=000;

8.To Remove IDD Facility

SOD:CLC,N=number,,,RC=004;

9.Check The Number Details

PSD:N=number;

10.To Add New Connection

SOD:NEW,N=number,EL=xxxxxxxx,30; (EL must include 8digits)

11.Delete Numbers

SOD:DSC,N=number,EL=xxxxxxxx;

then

SOD:UAN,N=number

12.Malicious Call Trace (This is Not a CLI support system)

MTR:REG,N=number


and also there are thousands of commands are using with this system.I just wanted to recall your memory.

VERY IMPORTANT Email

Today Morning I received This email from one of my friend.I do not know whether this story is true or false but this can happend.I think it will be useful to all of us.so I decided to to publish it in my blog.

-------------------------

VERY IMPORTANT

This is a real incident that happened in a local hospital in Bangalore , India . A 4 year old girl was admitted due to leg fracture. As it was an open fracture, she had to undergo an operation to stitch the protruding bone back in place. Though it was quite a minor operation, she was hooked on to life support system, as a part of the process.

The doctors had to input some data prior to the operation to suit different conditions. Thereafter, the operation proceeded.. Half way through the process, the life support system suddenly went dead.

The culprit : -

Some one was using his/her hand-phone outside the operation theatre. And the frequency had affected the system.. They tried to track the person, but to no avail. The little girl, young and innocent as she was, died soon after.

Be compassionate! Do not use your hand phone / mobiles especially at any hospitals or within the Aircraft or any places where you are told not to use it... You might not be caught in the act, but you might have killed someone without knowing.

Sometimes it's a matter of Life & Death.....!!!

Please pass this to as many, since most of us are just not aware of the seriousness of this issue.

Please Don't Delete. Please Send this to all your contacts and help save a life..

Last Word :

So friends, please avoid using your mobile phones in hospitals / petrol pumps / aircraft etc ... wherever it is mentioned no use of mobiles, go by the rules, it's a matter of life & death.

A tiny mail can save a life..

REAL INCIDENT....READ N PASS..

Long time no see

But

I will come again very soon....

Special attention....for Sri LAnkans

Just Dial

#132#

from your mobile phone....

(Dialog, Tiogo, Mobitel,Hutch)

If you are not the owner

Register Your SIM Now...

Try to reduce long time calls

A very important message to everyone,I reserved this as Email.
please read it carefully.


1 Egg, & 2 Mobiles
65 minutes of connection between mobiles.

We assembled something as per image:








Initiated the call between the two mobiles and allowed 65 minutes approximately...
During the first 15 minutes nothing happened;
25 minutes later the egg started getting hot;
45 minutes later the egg is hot;
65 minutes later the egg is cooked.





Conclusion: The immediate radiation of the mobiles has the potential to modify the proteins of the egg. Imagine what it can do with the proteins of your brains when you do long calls.

Please try to reduce long time calls on mobile phones and pass this to all your friends & Family you care for.

Dont use mobile phones when recharging

A few days ago, a person was recharging his cell phone at home.

Just at that time a call Came in and he answered it with the
Instrument still connected to the outlet.



After a few seconds electricity flowed into the cell phone unrestrained
and the young man was thrown to the ground with a heavy thud.

His parents rushed to the room only to find him unconscious,
with a weak heartbeat and burnt fingers.



He was rushed to the nearby hospital, but was pronounced dead on arrival.

Cell phones are a very useful modern invention.



However, we must be aware that it can also be an instrument of death.



Never use the cell phone while it is hooked to the electrical outlet!

My dear Friends I reserved this as E mail.
pls inform your friends about this matter....

City & Guild Telecommunication Diploma

My Friends,

What Can WiMAX Do?

WiMAX operates on the same general principles as WiFi -- it sends data from one computer to another via radio signals. A computer (either a desktop or a laptop) equipped with WiMAX would receive data from the WiMAX transmitting station, probably using encrypted data keys to prevent unauthorized users from stealing access.
The fastest WiFi connection can transmit up to 54 megabits per second under optimal conditions. WiMAX should be able to handle up to 70 megabits per second. Even once that 70 megabits is split up between several dozen businesses or a few hundred home users, it will provide at least the equivalent of cable-modem transfer rates to each user.

The biggest difference isn't speed; it's distance. WiMAX outdistances WiFi by miles. WiFi's range is about 100 feet (30 m). WiMAX will blanket a radius of 30 miles (50 km) with wireless access. The increased range is due to the frequencies used and the power of the transmitter. Of course, at that distance, terrain, weather and large buildings will act to reduce the maximum range in some circumstances, but the potential is there to cover huge tracts of land.

How Wi-MAX Works......

In practical terms, Wi-MAX would operate similar to Wi-Fi but at higher speeds, over greater distances and for a greater number of users. Wi-MAX could potentially erase the suburban and rural blackout areas that currently have no broadband Internet access because phone and cable companies have not yet run the necessary wires to those remote locations.

WiMAX transmitting tower

A WiMAX system consists of two parts:

• A WiMAX tower, similar in concept to a cell-phone tower - A single WiMAX tower can provide coverage to a very large area -- as big as 3,000 square miles (~8,000 square km).

• A WiMAX receiver - The receiver and antenna could be a small box or PCMCIA card, or they could be built into a laptop the way WiFi access is today.

A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T3 line). It can also connect to another WiMAX tower using a line-of-sight, microwave link. This connection to a second tower (often referred to as a backhaul), along with the ability of a single tower to cover up to 3,000 square miles, is what allows WiMAX to provide coverage to remote rural areas.

What this points out is that WiMAX actually can provide two forms of wireless service:

• There is the non-line-of-sight, WiFi sort of service, where a small antenna on your computer connects to the tower. In this mode, WiMAX uses a lower frequency range -- 2 GHz to 11 GHz (similar to WiFi). Lower-wavelength transmissions are not as easily disrupted by physical obstructions -- they are better able to diffract, or bend, around obstacles.

• There is line-of-sight service, where a fixed dish antenna points straight at the WiMAX tower from a rooftop or pole. The line-of-sight connection is stronger and more stable, so it's able to send a lot of data with fewer errors. Line-of-sight transmissions use higher frequencies, with ranges reaching a possible 66 GHz. At higher frequencies, there is less interference and lots more bandwidth.

WiFi-style access will be limited to a 4-to-6 mile radius (perhaps 25 square miles or 65 square km of coverage, which is similar in range to a cell-phone zone). Through the stronger line-of-sight antennas, the WiMAX transmitting station would send data to WiMAX-enabled computers or routers set up within the transmitter's 30-mile radius (2,800 square miles or 9,300 square km of coverage). This is what allows WiMAX to achieve its maximum range.

Special Thanks goes to Prabath Ariyarathna..

Be careful when you SMS......

A True Story:

This lady has changed her habit on the hand phone after her handbag was stolen.
Her handbag which contained her mobile, credit card, purse etc. was stolen.
Twenty minutes later when she called her hubby, telling him what had happened,
her hubby says 'I've just received your SMS asking about our
Pin number and I've replied a little while ago.'

When they rushed down to the bank, the bank staff told them all the money was already withdrawn.
The pickpocket had actually used the

stolen hand phone to sms 'hubby' in the contact list and got hold of the pin number.

Within 20 minutes he had withdrawn all the money from the bank account.



Moral of the lesson:

Do not disclose the relationship between you and the person in your

contact list. Avoid using names like Home, Honey, Hubby, Sweetheart,

Dad,

Mum etc...... and very importantly, when sensitive info is being asked

thru SMS, CONFIRM by calling back.

PLEASE PASS THIS story ON TO YOUR LOVED ONES AND FRIENDS

Potential New risk from mobile phones...

Please use left ear while using cell (mobile), because if you use the right one it will affect brain directly.

scientists have discovered that exposing human endothelial cells- which line the minute blood vessels in the brain - to mobile phone radiation can damage the blood-brain barrier,a vital safety barrier that stops harmful substances in the blood from entering the brain.

I reserved this as an E mail........I think It will useful to you, now you can find about this matter.
