Помогите чайнику.

[Vlad_Ig]

Помогите пожалуйста правильно настроить модем. Пытался методом проб и ошибок, но как видно без помощи специалиста не обойтись АТС аналоговая, хотелось бы на 100% использовать возможности модема

[Technical Support]

Попробуйте поработать с такими строчками инициализации:

S91=15 S210.7=1 +MS=,,,36000

и

S91=15 S210.7=1 +MS=11

С каждой из строк нужно провести сеанс длительностью минут 5-10, и обеспечить загрузку модема на приём (скачивайте архивированный файл). Покажите статистики для каждой строки.

Модем провайдера: 735-000 Ascend MAX. V.90 56000
Стоит ли опробовать другие модемы провайдера:
Microcom Integrated Modem 2.2 (Cisco)
INPRO IDC 2814 BXL+
TAINET T-288 Nc
USRobotics Courier V.E.
на разных АТС города?
Спасибо.

[Technical Support]

Печальная картина. Такое впечатление, как будто бы на линию временами подключают мощный генератор шума

SNR Last/Min/Max............. 43/17/43
SNR Last/Min/Max............. 14/14/43

Видите, как прыгает SNR. И с EQM не лучше:

EQM Last 10 Readings......... 6 61 58 26 13 126 127 127 125 125

В общем, картина разительно отличается от первой статистики. Кроме того, видны последствия команды S210.4=1, которую выдавать не просили. Что всё это значит?

Большое спасибо за консультацию, буду эксперементировать.
И еще, подскажите пожалуйста, где можно найти информацию о методах анализа полученной статистики?

Кое-что есть в FAQ. Но главное для понимания статистики - знание протоколов модуляции, коррекции ошибок и сжатия данных. При наличии этих знаний дополнительных комментариев не требуется
