In Reference of “Places Building of Health” catalog, it has been programmed “The National Record of Places Building of Health (RENAES)”, through a web interface every Health Institution in the country should be filled information related to its own institution and later the update information process should be responsible to every institution (administration) while the system generates an own code identification appended a new record to IEDS database then query information can be accessed by internal and external users.

Auditing report of Minister of Transport and Communications of Peru (MTC)

Product : Auditing report.
Part involved : Minister of Transport and Communications of Peru (MTC).
Summary : Through this report MTC tryes to explain to peruavian citizens what happened when mobile phone communications and land phone communications crashed on August 15, 2007.
Scenario : That date our country was shaken by 2 consecutive earthquakes of 7.5º on Richter scale and after that the communication was lost upto 6 hours in main city (Lima) and several days near to the epicenter (Chincha and Ica -200 Kms south of Lima-).
Company : Owner.
Reference date : September 2007.

Today MTC has published the auditing report in http://www.mtc.gob.pe/portal/Informe%20Nº%20009-2007-MTC-29.pdf to achieve with next goals :

- To decide on capacity of Public Commute Branch Exchange.
- To decide if the capacity of traffic management system and the size of telecommunication networking are enough to attend the requirements of telephone communications of the suscribers.
- In the case of mobile phone service, look at the level of working of cells.
- An additional actions to be necessary.

While OSIPTEL has published two documents in : (1) http://200.89.2.171/Index.ASP?T=T&P=GCC%2FNOTICIAS%5FPUBLICACIONES%2FNOTAS%5FPRENSA%2FFILES%2FNP+Resultados+de+Comision+de+Alto+Nivel%2Epdf (2) http://200.8.92.171/Index.ASP?T=T&P=GCC%2FEL%5FSECTOR%2FNORMAS%5FOSIPTEL%2FFILES%2Fres%5FPD%2F2007%2Fres1232007PDOSIPTEL%5Finforme%2Epdf about the same subject.

The auditing report of MTC shows a delimited sections of every mobile phone operator. Next parameters are defined as : IC-TINE (attempt not connected), TTLI (callings fallen) and summary of them :

Nextel (Mobile phone carrier operator)
Cpu (qty) = 1
Cpu % = 67
IC-TINE = 3
TLLI = > 2
Subscribers= 390,000
Traffic Channels= 4,604
Users/Channel= 84.70

MoviStar (Mobile phone carrier operator)
Cpu (qty) = 6 MGW
Cpu % = 70
IC-TINE = 4.03 (April), 6.41 (May), 3.48 (June), 4.54 (July)
TLLI = (No information)
Subscribers= 7,637,504
Traffic Channels= 141,492
Users/Channel= 53.98

Claro (Mobile phone carrier operator)
Cpu (qty) = (No information)
Cpu % = 72 and 98
IC-TINE = (No information)
TLLI = (No information)
Subscribers= 4,521,412
Traffic Channels= 138,203
Users/Channel= 32.72

Telefónica (Land Line carrier operator)
Cpu (qty) = 5
Cpu % = 60
IC-TINE = (No information)
TLLI = (No information)
Subscribers= 2,340,000
Traffic Channels= (no information)
Users/Channel= (no information)

Telmex (Land Line carrier operator)
Cpu (qty) = (no information)
Cpu % = 43
IC-TINE = (No information)
TLLI = (No information)
Subscribers= 28,530
Traffic Channels= (no information)
Users/Channel= (no information)

In Claro's case the auditing report suggests an acceptable value of "Users/Channel" (32.72), while at the same time does not confirm the rest values indicated under the reference (no information) and clears the responsabilities between MTC and OSIPTEL (Telecommunication Supervisor Body) such as next table :

Duties of MTC
Supervision of implementation networking (first 12 months)
Fill goals of the spectrum.
Fill goals of secret of communications.

Duties of OSIPTEL
Check quality and efficiency in public telcommunications services.
Check the goals and obligation to expand services.
Check to fulfilling the contract as carrier operator.

In the auditing report of OSIPTEL, we can find :
-IC-TINE and TLLI superpassed 3% in MoviStar, Claro and Nextel since previous months ago to earthquake.
- It founded 807,900 callings lost at peak hour (it is an abuse!)
- Most of calling cases are GoS are 1%.

I am going to suppose that :
(a) The quantity of traffic channels busy in Lima reachs up to 70,476 (assumed only 55% from the overall) multiply by 300 minutes, and every one minute had a cost average of S/.050, then the big business for MoviStar was for that event (after earthquake) the profit of S/. 10'571,400 ( US$ American Dolar 3,410,129.00).
(b) But I am going to give to MoviStar the benefit of the doubt according to the previous paragraph : only the half of the overall traffic channels made (dial) the call becuase the other half received the call, then the profit is US$ 1,705,064.00).
(c) There is no any rule and local law to establish the maximum ratio and relation to the parameter "Users/Channel", that is, if the carrier operator exceeds that parameter then this one should be forbidden to sell additional mobile phones. -You want to sell more mobile phones then first build the networking wireless to use-.
(d) The end user at the time of buying a new mobile phone should be noticed about the available traffic channels and another networking resources offered by carrier operator.
(e) The advertisment on news paper, tv and others medias to sell mobile phones should be included additionals indicators of quality of services and availability of networking services, that can be access too, by links of www.
(f) The auditing reports does not confirm an absence of call service and that means, that was a super plus of calling service?, and what happened with suscribers did not connect never at that time?. Both auditing reports confirm deficiency of planning networking telecommunications and degraded of call service but at this point the main reason of typing the auditing report was to confirm what suscribers were feeling at that day ?, is not explained what was the main reason calling services crashed on August 15.

Lost Internet

Product : Linux.
Part involved : Squid.
Summary : Users can not access to internet.
Scenario : Troubleshooting internet service of end users .
Company : National Institute of Cancer Sickness of Peru (INEN).
Reference date : May 2005.

The main functionality of internet connection is based on "rcinetd" service running on Linux, then is possible to get up it swaping the states of that service, such as :

/etc/inetd.conf
rcinetd restart
cd /var/spool/mail
vdir
du -h
tail -f /var/log/mail
tail -f /var/log/httpd/access_log
tail -f /var/squid/logs/access.log
last more
vi /etc/passwd
bi /etc/shadow

And, after that, it persists a lost of internet service then try with ping command from your gateway to outside if there exists any other response, in negative answers check your connection with your ISP.
