P AR T I Domestic fixed communications  Domestic fixed communications revenues comprised 36.0% and 34.9% of our revenues in 2009 and 2010, respectively. Our  domestic fixed line revenues decreased by 1.1% from NT$71.5 billion in 2009 to NT$70.7 billion in 2010.  Local telephone services.  Our local telephone revenues decreased from NT$33.2 billion in 2009 to NT$32.3 billion in 2010.  This reflects a 6.4% decline in traffic volume from 14.6 billion minutes in 2009 to 13.7 billion minutes in 2010, offset by a 0.5%  increase in average local usage fees. The decline in traffic volume was primarily due to the traffic migration from fixed line services  to mobile and internet telephone services. We expect this trend to continue as broadband and mobile services become more widely  adopted in Taiwan. However, we believe the rate of such migration is slowing down. Our local interconnection revenues decreased  by NT$77 million (US$2.6 million) from 2009 to 2010 because of the decrease in fixed line to mobile voice traffic volume of calls  terminating on mobile networks of alternative operators.  Domestic long distance telephone services.  Our domestic long distance telephone revenues decreased by 10.2% from  NT$7.4 billion in 2009 to NT$6.6 billion in 2010. This decrease was mainly due to a decrease in traffic volume from 3.6 billion  minutes in 2009 to 3.4 billion minutes in 2010 and domestic long distance interconnection tariff decreases mandated by the National  Communications Commission. The decrease in traffic volume was primarily due to the continued traffic migration from fixed  line services to mobile services and VoIP. Our interconnection revenues also decreased primarily because the telecommunications  operators construct their own interconnection circuit.  Broadband access.  The number of our ADSL customers decreased from 2.7 million in 2009 to 2.3 million in 2010 due to  customer migration to our FTTx services. There was an increase in the number of FTTx customers from approximately 1.6 million in  2009 to approximately 2.0 million in 2010. Broadband access revenue increased from NT19.9 billion for 2009 to NT$20.3 billion for  2010.  Domestic leased line.  While demand for higher speed leased lines continues to increase, our overall leased line tariffs have  continued to be adversely affected by competition from other fixed line operators, as well as the continued migration of domestic  leased line customers to broadband services. Domestic leased line revenue decreased from NT$6.7 billion for 2009 to NT$6.1 billion  for 2010.  MOD.  Our MOD revenues increased by 9.9% from NT$0.9 billion in 2009 to NT$1.1 billion in 2010. This increase was  mainly due to an increase in the average revenue per user. In addition, since 2010, MOD revenues include billing fees and advertising  revenues, which was previously accounted for under domestic other services.  Mobile communications  Revenues from our mobile communications business segment comprised 43.6% and 44.0% of our revenues in 2009 and  2010, respectively. Revenues from our mobile communications business segment increased by 2.9% from NT$86.5 billion in 2009 to  NT$89.0 billion in 2010. This increase was principally due to the growth of mobile VAS revenue and handset sales revenue offsetting  the decline of mobile voice revenue over years. The growth of mobile voice traffic due to the general recovery of the economy in  the R.O.C. partially offset the impact from the mandatory tariff reduction, which helped slow down the decline of the mobile voice  revenue in 2010.  Mobile services.  Revenues from our mobile services comprised 36.0% and 36.1% of our revenues in 2009 and 2010,  respectively. Revenues from our mobile services increased by 2.3% from NT$71.4 billion in 2009 to NT$73.1 billion in 2010 due to  the growth of mobile VAS revenue from NT$8.4 billion in 2009 to NT$ 11.1 billion in 2010, offsetting the decline of mobile voice  revenue. The growth of mobile traffic volume due to the general recovery of the economy in the R.O.C. also helped slow down the  decline in mobile voice revenue.  Sales of mobile handsets and data cards.  Revenues from our sales of mobile handsets and data cards comprised 7.6% and  7.9% of our revenues in 2009 and 2010, respectively. Revenues from our sales of mobile handsets and data cards increased by 6.1%  81
