AT-GS950/48
Коммутаторы Gigabit Ethernet серии WebSmart GS950 от Allied Telesis представляют собой недорогие коммутаторы Gigabit Ethernet, настройка которых может осуществляться через браузер или локальное подключение RS232. Такие коммутаторы для сетей Gigabit Ethernet могут служить превосходной альтернативой устройствам, управляемым через SNMP, в системах для сотрудников, работающих с информацией. Коммутаторы серии WebSmart поддерживают управление качеством обслуживания (QoS) и механизмы приоритизации пакетов. Модели GS950 отлично подходят для транспортировки по сети трафика голоса, видео и данных.
