Race to restore the communication links essential to humanitarian assistance

ITU has deployed 25 satellite terminals to help restore vital communication links in the aftermath of the massive 8.8-magnitude earthquake and tsunami that hit Chile on 27 February, killing over 700 people and cutting communications links in the city of Concepción and towns along the coast.

In a press release, ITU indicates that the equipment was airlifted out of Geneva on Monday 1 March, and is expected to be deployed on the ground as early as today, 2 March. ITU is working with emergency communications partner Iridium Communications Inc. to ensure connectivity for satellite handsets, which will be used by local authorities to facilitate humanitarian assistance to disaster victims. ITU is also striving to source additional equipment from El Salvador and Nicaragua, where it had been deployed last year to help those countries restore communications after their own natural disasters.

“Our hearts go out to the government and the people of Chile, who find themselves having to deal with a tragedy similar to that which so recently devastated Haiti,” said ITU Secretary-General Dr Hamadoun Touré. “We are proud to be a long-standing leader in coordinating the provision of emergency telecommunications and will continue to actively contribute assistance in partnership with ITU membership.”

ITU’s Area Office in Santiago, Chile, is already providing expert on-the-ground support to local authorities, as well as to the local UN Operations Centre, to coordinate the restoration of damaged communication systems and manage spectrum requirements for the wireless systems used by humanitarian agencies.

Sami Al Basheer Al Morshid, Director, ITU Telecommunication Development Bureau, said: “I would like to thank Iridium for supporting ITU on this sad occasion. Communications networks were disrupted by this massive earthquake, hampering rescue operations and the delivery of essential logistics and services. Our assistance will contribute towards the bridging of the current communication gap.”

ITU is providing Iridium satellite phones which can use both satellite and GSM networks, as well as delivering accurate GPS positioning coordinates to aid relief and rescue. ITU covers all expenses relating to transportation, deployment and use of equipment, which will be at the disposal of the authorities in Chile for as long as they require it.

Its another busy week, one problem I encounter that I want to post here is about a LAN connection problem on a problematic RJ45 connection.

The problem indicates a no connectivity even if LAN cable is inserted(take note that this is a previously working connection), on the first look of the situation there are possible scenarios that may have caused it, it maybe cause by problematic LAN cable or RJ45 connection,a LAN card problem or perhaps a software problem.

The first thing I did is checked and re-crimped(without replacing the connector) both ends of the LAN cable(visually connection looks fine) but problem still the same. I go ahead on replacing a different LAN card(PC is using a PCI LAN card), when I rebooted the system it detects the new hardware and load the corresponding driver but still a no connectivity exist. What else is left, a cable or a software problem? this will requires a lot of work if I will replaced either of the two, so I look for other ways to confirmed the problem.

Before I continue, I just want to add more info about this particular problem, the problem occurs after the two PC has switched location.The reason I include this fact because this will be bring twist to the problem. I re-inserted that problematic cable to another PC, it’s actually the one being previously switched and to my big surprise the connection did work fine.

I re-insert both PCI LAN card to the other PC, still no connectivity exist. The LAN device used on the particular PC where the particular connection work is on board(strange?), I replaced both RJ45 connectors on the problematic connection and connectivity backs to normal.

Conclusion
A not so good RJ45 connection exists from the very beginning the LAN cable was installed its just it works on the original PC which is using an on board LAN, the problem was only discovered when the user switched PC.

I just want to discuss a particular network problem I encounter just recently, it’s actually an additional connection to the router, the cable is just newly bought and crimped from the store.

The problem encountered is when you plugged the cable, network icon indicates a limited connectivity and shows an exclamation point. It took me sometime to trouble shoot the problem, but later I found out that CAT5 cable is not crimped based on standard configuration.

The hard part in identifying the problem is that LAN cable is newly purchased so it’s the least you suspect.In case you encounter similar problem described above, try to inspect the connector visually or adjust network connection properties to 10 mbps full duplex(default setup is auto), if PC established network connectivity then it’s confirmed that connector was not crimped in accordance to standards.

It is important than you observe proper cable configuration when crimping new connections to ensure a problem-free network.
