Есть вопрос о том, сможет ли реально AS5300, в которой наличествует модуль на 8 E1-портов и 2 модуля по 120 модемов разруливать эти 240 линий одновременно? Не загнётся ли она под нагрузкой?
такой вопрос уже задавался здесь и на него отвечали.
впрочем, можно и ещё раз ответить :)
вот пример с кошки, в которую воткнуто все 8 E1
