ОБЩИЕ УКАЗАНИЯ
Контрольное задание состоит из двух объемных заданий, в каждом задании по десять вариантов. Студент должен выполнить все задания своего варианта. Вариант определяется по последней цифре номера зачетной книжки студента. Рассшифровка трейсов задания должна осуществляться согласно форматов протоколов сигнализации DSS-1,ISUP, с обоснованными пояснениями.
ОФОРМЛЕНИЕ КОНТРОЛЬНОГО ЗАДАНИЯ
Работа должна быть аккуратно оформлена. Надо придерживаться следующих правил:
1. Задания рекомендуется выполнять том же порядке, который указан в методическом указании по выполнению заданий.
2. Перед выполнением каждого задания необходимо написать трейс согласно варианта.
3. Не допускайте, пожалуйста, небрежного выполнения рисунков и пояснений.
4. В конце работы привести список источников, которыми Вы пользовались, дату окончания работы и подпишите ее.
5. Работу необходимо выполнить на формате А4.
6. Рецензирование работы выполняет ПЦК СССК СибГУТИ.
7. Если в работе имеются отмеченные рецензентом ошибки, их необходимо исправить.
8. Работа должна быть зачтена прежде, чем Вы будете сдавать зачет по курсу.
Если работа не зачтена, то студент выполняет ее заново полностью.
КОНТРОЛЬНЫЕ ЗАДАНИЯ
