Помогите настроить IDC-5614BXL/VR+

[abaz]

Здравствуйте!

Модем IDC-5614BXL/VR+(заземление отключено). Линия цифровая, уплотненная. Пользуясь Вашими рекомендациями на форуме, отключил НЧ-фильтр - качество связи улучшилось(возросла стабильность). Строка инициализации следующая: +MS=,,,32000 S91=15 S210.7=1 S17=52 s11=5 s55.4=1. Что еще можете посоветовать в моем случае?

[Technical Support]

Фильтр НЧ помех работает на V.90, а Вы соединяетесь на V.34.

Попробуйте такую строку инициализации:

S91=15 S210.7=1 S210.4=1 +MS=11

и покажите, что получается в статистике. Да, вот ещё что: после замены строки инициализации выключите и снова включите модем.

Выходит, прирост никак не связан с отключением НЧ фильтра. Поменял строку - привожу статистику:

Нет, фильтр тут не при чём. Теперь попробуйте заменить команду +MS=11 на такую:

+MS=11,,,26400

и покажите статистику. Скорее всего, это и будет "окончательный приговор"...
