Связь стала неотъемлемым атрибутом эпохи. Сегодня без нее немыслимо развитие практически любого бизнеса, любого производства. Все больше компаний нуждаются в протяженных каналах связи с различной пропускной способностью. Все больше неспециалистов невольно оказываются вовлеченными в сферу влияния телекоммуникаций. Это неизбежно ведет к тому, что между поставщиками телекоммуникационных услуг и их клиентами возникает недопонимание, и одним из камней преткновения здесь является качество предоставленного канала связи и критерии его оценки. Вопрос этот достаточно сложный, но чрезвычайно важный. К сожалению, многие проблемы вызваны терминологической и методологической путаницей вследствие разнообразия стандартов и норм, как отечественных, так и зарубежных.
Цель статьи – помочь сталкивающимся с такими оценками инженерам и менеджерам разобраться в применяемой терминологии, типах ошибок, а также диапазонах изменения параметров и возможном порядке величин в конкретных случаях. Эти знания позволят более квалифицированно составлять договоры, обоснованно предъявлять требования провайдерам и контролировать выполнение взаимных соглашений.
