  1. 1. Department of Engineering North South University Project- Project topic: VOIP Solution in Nepal Prepared by … Sk.Ashikur Rahman ID# 072-874-556 ETE-605 Dept. of Electronics & Telecommunication Engineering North South University Dr.Mashiur Rahman Faculty of Computer Science & Engineering Department North South University, Dhaka.
  2. 2. VOIP Issues in Nepal Technologically, VOIP is not an issue. The exisiting policy do not prohibit the use of VOIP technology. But it specially prohibits providing end user telephony service. The bone of contention with existing situation, is illegal use of NTC's telephone service to terminate international calls. The policy doesn't at point prohibits the carrying of Voice in data form, and thus the reluctance of parties concerned to go to court of law. The use of VOIP technology is a result of lack of competition in telephony service, which has enabled NTC to keep the price of it's domestic services subsidized through international revenue. This is also partly result of NTC's non co-operation with ISPs in their initial stage of functioning. * Telecom liberalization should be taken forward at speed. This may mean bringing the dates for complete opening of telecom services earlier * The current thought of licensing particular technology is short term thinking and should be discouraged. * The incumbent telecom provider should be divided into different units, and cost based tariff implemented to disable cross subsidy of tariff. * International movement in telecommunications, and data networks needs to be more closely monitored and technologies made welcome by the authority to avoid illegal use of such technologies in future.
  3. 3. -- unofficial notes VOIP in Nepal started around mid-1999, after VSAT services were allowed, and ISPs could afford bandwidth. There were a couple of factors in why ISP did that * The ISPs were paying phone bills for the phones that were being used for dial-in only access for subscribers. This was a complete wastage of their resources, and they wanted to make use of it. NTC didn't want to talk about it , despite strong lobbying by organizations here. Their contention – since we are loosing money to e-fax, and e-mail, we will continue charging it. * The more appropriate reason was the high accounting settlement rate of NTC with international operator. As late as Sept 2001, the accounting rate was USD2, thereby resulting in a settlement rate of USD 1.00 for NTC. This was very very high by International standards, and naturally companies shopping for cheaper rates found a cheaper way to terminate calls. * Last year, around June 2001, there were almost 10 VOIP phone operators (basically bypass operators – they used NTC's subscribers line to terminate calls locally). some had big operations (ask internationally for big bandwidth buyers in Nepal.. :-), and you'll know the companies) * The main reason for NTC creating the noise was the deep cut in it's revenue from settlements. In the year 98/99 (fiscal year), it was around USD15million (translated figure – do not quote.. can provide exact amount if required).. It dropped to around USD11 million in one year. the impact was only half, as it takes around two years to completely settle the amounts. the drop is probably sharper going by the recent crackdown by NTC on operators. * The number of minutes have also decreased sharply – from 2.2 million minutes earlier to 1.7 million minutes (in august 2001) per month. * In call percentage as well this drop was seen – specially in calls originating in USA. While total
  4. 4. incoming calls from US were around 20% in 98/99, in April 00, it was only 6% of total incoming calls. This was not VOIP, but traffic was being re-filed through New Zealand. * For sometime afterwards, to take revenge (??) on AT&T, NTC refilled all of its traffic through Singapore. Ironically, Singtel was sending inwards traffic through cheaper bypass operators. – A NTC guy told me.. this ..:-) * NTC decreased it's accounting rate for 2000 to 60 cents and for 2001 to 30 cents, which has now made operations difficult. Major operators now go with NTC again, as the ASR (Acute Seizure Rate) is almost 70% country wide with NTC, while with VOIP operators, it is around 50% for Kathmandu, and lot less for outside valley. * A source inside NTC told me that, since 1997-98 itself, the volume of international traffic had not grown proportionately, which it should have –owing to good international economy largely due to increased use of e-mail, and e-fax. But, most of this shortfall was made up by local revenue arising out of internet usage. NTC was alarmed, when call rates actually dropped. He actually said – if there were not so may VOIP operators, there would probably not have been such a fuss.. * VOIP operators, as their numbers grew.. compromised on quality in order to make call cheaper. some were even using only 6K per voice channel.. making connections from many countries impossible. For example, in June 2001.. I couldn't make a call from Stockholm to kathmandu despite repeated tries with the calling card. Using Telia's business network – it was possible. These concerns reach the public/ governments quickly – but they don't understand the underlying dynamics of international telecom. * People inside NTC too realize that this cannot be stopped., and if they stop cross subsidizing their domestic operations with international revenue * From HMG's perspective, which is highly skewed
  5. 5. by NTC's reporting of its revenue – the biggest concern seems to be decreasing revenue. Operators and industry has been contending that if the VOIP operators can be brought under tax net, then the revenue will actually grow – while NTC's income may decrease. But government sources (the bell heads), don’t' seem to get the point. * NTC actually uses VOIP technology in some of its trunk routes to increase existing capacity, which make the question of quality and technology irrelevant. new Developments The telecommunications authority is hard at work to publish the new regulations legalizing VOIP operators. But it seems that it is buying time, so that when time comes for opening up of telecom sector in basic services (2004).. the licensing can allow all sorts of things. Thereby making things easier to license and less administrative work. The regulations could be skewed (check out India's – a lot of it doesn't make sense to us net heads). which is why currently there is a huge lobbying effort ongoing. My Conclusions * NTC should be privatized – or it be broken up like AT&T, and private parties be able to tap into its national backbone. * Technology specific licensing should not be allowed * The date for opening of basic services should be brought earlier, so that there can be fair competition. but without breaking up NTC.. competition will never succeed as there would issues with interconnection and laying fibre all over the city and country.
  6. 6. Nepal routes Needed AD 240 12/16 KHz Billing Pulse Generator The Concept The AD240 Billing Pulse Generator is designed to locally produce 12 or 16 KHz billing pulses. It can generate billing pulses for up to 2000 prefixes (max 8. digits). The billing start can be triggered by either polarity reversal or by a DTMF tone. When is it needed? Enterprises using local call accounting and billing solutions that are dependent of the 12 or 16 KHz billing pulse services provided by national telecom carriers, will be unable to bill the calls sent via alternative carriers like ITSP since those carriers don’t supply these billing pulses. For these cases, the AD240 can be integrated in their telecommunications system in order to produce the required billing pulses locally. The AD240 is a 4 port device that can generate billing pulses on 4 Trunk lines independently. How does it work? The AD 240 should be connected in serial between the PBX and the interconnection device(s) (gateway or auto dialer) on the CO lines. This way, the AD240 Billing Pulse Generator can capture the dialed number and compare the prefix with its prefix table. If, the prefix of the number dialled can be found on the configuration table along with a period of pulses, , the AD240 Billing Pulse Generator will produce billing pulses by given interval. The AD240 Billing Pulse Generator can be connected to a PC via a USB cable. Thanks to the accompanying software, you can easily access and modify the rate table as well as the trigger properties of the device.This PC connection is only necessary for setting up or modifying the rate table. Normal operation does not require a PC.
  7. 7. Nepal VOIP to get legalised? They say one man’s meat is often another man’s poison, and for us VoIP lovers – especially the Nepali VoIP lovers – this couldn’t be truer. What came as a rude shock to the Nepalese Government is a celebration cause for all advocates of VoIP. After an estimate revealed that the Government is losing NRS 8 billion annually due to illegal International Long Distance call bypass services offered by VoIP powered public phone booths and cyber cafes, the Nepal Telecom Authority has finally given the green signal to United Telecom Limited and Nepal Telecom to employ VoIP technology. And when you come to think of it, who can blame them? If I was losing that kind of money, I’d want it back too! United Telecom Limited is a Bangalore based joint venture between India’s MTNL, VSNL and Telecommunications Consultants India. In Nepal, it operates in collaboration with Nepal Venture Private Limited, and is also the country’s first private telecom operator. Nepal Telecom – the other company that has been given the go-ahead – is a state owned enterprise. The VoIP project is still in its initial phases, with UTL only beginning to conduct feasibility studies to identify partners it can ally with overseas to offer the new technology to its subscribers in Nepal. If initial estimates are to be believed, UTL will need to invest about NRS 150 Million (Over $2 Million) to implement the new technology. I like the fact that the government has granted licenses to two companies to negate the possibility of a monopoly. But even though everything seems bright and positive so far, I won’t be surprised if hitches crop up in the plan concerning the rights and licenses of the two telecom operators. Discrimination against the privately owned UTL is not unheard of in Nepal, and petty politics could spoil the whole thing. An example of the prejudice would be that even though both UTL and Nepal Telecom have identical licenses to offer phone service based on the wave technology employed by cellular phones, the Nepal Telecom Authority has allowed Nepal Telecom to offer full mobility to their customers, while UTL has been restricted to limited mobility. This means that while a UTL subscriber can use his phone as a mobile only up to a certain area, Nepal Telecom’s phones using the same technology can be used anywhere in the country. If such discrimination seeps into the new VoIP plan, it can be a heavy setback to the development of a strong, robust VoIP network in Nepal. This post is written by Samarth Chandola.

  11. 11. UTL gets Nepal nod to start VOIPservice Tuesday 26th of June 2007 Indian joint venture United Telecom Ltd, the first private operator in Nepal's telecom sector, has been given the go-ahead to start VOIP (voice over internet protocol) service - a technology that is expected to slash international long distance (ILD) call costs from here substantially. After the green signal came from Nepal Telecom Authority (NTA) late last week, UTL, a joint venture between India's MTNL, VSNL and Telecommunications Consultants India Ltd and Nepali partner Nepal Venture Pvt Ltd, has begun a feasibility study to identify the partners and phone routes it can ally with overseas to offer the new technology to its subscribers in Nepal. Though the study will take at least a month, according to initial estimates, UTL will need to invest about NRS 150 million (Over $2 million) to implement the new technology. Along with the Indian joint venture, NTA also authorised the state agency, Nepal Telecom, to operate VOIP technology. VOIP is a technology and not Internet services used for call bypass by illegal operators. The move comes after the Himalayan nation has been losing annually around NRS 8 billion, at a conservative estimate, due to illegal ILD call bypass services offered by public phone booths and cyber cafes mushrooming all over Nepal. Though Internet calls - routing ILD calls through computers by adding a voice card and other modifications - is illegal in Nepal, as in India, phone booths and cyber cafes in both countries thrive on it, causing the government as well as telecom service providers a loss of billions. The VOIP technology means sending calls through several routes simultaneously though without using the Internet. The Nepal gesture comes as a placatory offer after NTA made a discriminatory gesture earlier this month. Though UTL and Nepal Telecom have identical licences to offer phone services based on the wave technology employed by cellular phones, NTA this month allowed the Nepali company to offer full mobility while UTL has been given only limited mobility. This means while a UTL subscriber can use his phone as a mobile only up to a certain area, Nepal Telecom's phones using the same technology can be used anywhere in the country, like mobile phones. This is not the first time that UTL has suffered discrimination. Though its licence, acquired in 2002, said it would be able to offer ILD calls to both UTL and Nepal Telecom subscribers from 2004, the facility was given only in 2006. Also, during the 15 months that King Gyanendra ruled Nepal from February 2005, triggering violence and intense political instability, UTL phone services were closed for six times, causing a loss of millions.

  13. 13. CONCLUSION: In order for Nepal to communicate among the rural areas remotely. Nepal VoIP example can be a guideline for most economic & practicable telephone system based on VoIP system affordable to most Nepalese in Nepal and abroad. Legalizing VoIP in Nepal, I fervently believe that the examples set by our neighbouring countries especially SAARC countires will be the right path to follow for the most economic and practical overall communication systems so that every single Nepali citizen will benefit from the latest technological development in VoIP. NTA to equip themselves with latest technological know-how, required specialized manpower, monitoring equipments for QoS etc. to regulate the market in the best consumer interests.
