We believe the Company 's poor performance is due primarily to a convoluted and ineffective growth strategy made worse by poor execution and failed oversight . Tollgrade is a small player in the telecom equipment industry . The core of Tollgrade 's existing businesses is legacy hardware and software solutions that allow telecom operators to manage their legacy copper networks . This is the market for which the Company is best known and in which it has had success historically . However , Tollgrade has aggressively pursued broad and wide ranging product development initiatives and acquisitions outside its core competencies spanning multiple industries on a global scale . These include products for next generation telecom networks , power utilities and , up until recently , cable operators . These initiatives have , for the most part , failed . Tollgrade has lost focus on who are its key customers and how to best serve those customers with products and services that the customer actually needs and would purchase from Tollgrade .
