| On April 27, 2000, TTNet made changes to technical documentation concerning its high-speed digital transmission service and Type I TTNet computer network service. TTNet revised the documentation as it starts to use its own optical fiber and metallic cables for high-speed digital transmission services economy and simple classes. Documentation was also revised because the company renamed its "Computer Network Service" to "Type I TTNet Computer Network Service" (TTCN) since it added new services as well as high-speed digital and ATM-specialized circuits. |
