Trace log EDSS1 (ETSI PRI). Лог D канала PRI потока. Сигнализация Euro ISDN DSS1. |
 |
Это вобщем то и статьёй тяжело назвать, так как в данном материале представлен трейс D-канала потока PRI с сигнализацией EDSS1. Думается что этот лог будет интересен для изучения как молодым специалистам, так и многим специалистам со стажем, для понимания процессов и сообщений которые появляются в следствии эксплуатации или настройки потоков данного типа сигнализации.
