Mr. Oo cited a situation in 2013 where a fire at a SingTel facility caused essential services to be lost, including for clients of various telcos.  ,
There seemed to be a lack of circumstances in that case, he said, and also so in this year’s disturbance.
For essential services and facilities, there should be reliability, he said, referring to the process of intentionally having copies so a program is more dependable.
” If you have duplication, you should not come down for three days, right? You should be able to quickly move over”, he said. ” Reliability means that you’re constantly on”.
The , Infocomm Media Development Authority ( IMDA ) has started investigations into the disruption. It can impose a financial penalty of up to S$ 1 million ( US$ 766, 000 ) or 10 per cent of the annual turnover of Singtel, whichever is higher.
What’s the potential for handsets?
Additionally, Asst. Prof. Purnima cited an IMDA report from June that recommended connections between ISDN facilities and “next generation systems”.
In the event of ISDN disruptions, Internet equipment may act as an automatic backup once it is in place.
CNA has inquired with IMDA when this will start.
On circumstances, the expert said in a statement even sent to other advertising that Singapore’s sites provide communication across words, mobile, broadband, Wi-Fi and messaging through various service companies. ” This variety is a vital part of our system resilience”, a spokeswoman said.  ,
In contrast, StarHub has stated in a part of its site that ISDN and Public Switched Telephone Network services will become disabled in 2025.
CNA has contacted IMDA to get this assurance.
