of the returned letters of credit from usac and were reimbursed for these penalty fees by at & t mobility llc in january 2014. we began the construction of our wholesale mobility funds projects during

revenues generated by our operations in certain smaller rural markets already covered by our wholesale network in the western united states . wholesale revenue is generated from providing mobile voice or data services to the customers of other wireless carriers , the provision of network switching services and certain transport services using our wireless networks . wholesale wireless revenue is primarily driven by the number of sites and base stations we operate , the amount of voice and data traffic from the subscribers of other carriers that each of these sites generates , and the rates we are paid from our carrier customers for carrying that traffic . story_separator_special_tag in addition , we recorded $ 1.1 million and $ 0.6 million relating to our discontinued operations for the

long-distance revenue was offset by data revenue growth from our newly built fiber optic submarine cable . wireline revenue in the u.s. remained relatively consistent compared with the previous year as we saw increased revenue from our upstate new york wholesale transport service business . we continued to add business customers in the u.s. for our voice and data services ; however , the overall revenue increase was offset by a decline in the residential data business in vermont and new hampshire , including dial-up internet services . equipment and other revenue . equipment and other revenue increased by $ 1.9 million , or 30 % , to $ 8.0 million for the year ended december 31 , 2012 , up from $ 6.1 million for the year ended december 31 , 2011. the increase was the result of an increase

as a result of a decrease in voice traffic volume and a reduction in bad debt expense . these decreases were partially offset by the termination and access fees in our u.s. wireline segment increased by approximately $ 1.7 million as a result of the expansion of our wholesale transport networks in vermont and new york state . engineering and operations expenses . engineering and operations

primarily as a result of the continued expansion of our u.s. wireless and international integrated telephony networks which resulted in increases in engineering and operations expenses of $ 2.6 million and $ 2.1 million , respectively . the remainder of the increase was the result of the completion of our bermuda merger in may 2011 and the expansion of networks and new services being offered in our international subsidiaries . sales and marketing expenses . sales and marketing expenses decreased by $ 1.2 million , or 6.2 % , from $ 20.2 million for the year ended december 31 , 2011 to $
