Похоже, у Вас цифровая АТС, и проблемы в виде импульсных помех. Нет ли у Вас параллельных телефонов с АОН? Проверяли, нет ли конденсаторов в розетках?

Параллельные телефоны есть, но при отключении ничего не помогает Розетки проверял, ничего нет.
Единственное что меня смущает из-за чего может быть, это из-за охранного пульта.. Можно ли что то сделать?
Спасибо!

[Technical Support]

Охранная сигнализация - враг модемной связи. Если возможности проверить/отключить у Вас нет, то будем стараться адаптировать модем к той ситуации, которая есть.

Попробуйте прописать такую строку инициализации:

S91=15 S210.7=1 S210.4=1 S17=64

и пересоберите статистику. Нужно сделать так, чтобы модем "усиленно принимал данные" - скачайте какой-нибудь архив.

Вы правильно сделали, добавив S55.4=1 в строку инициализации. Действительно, в некоторых Ваших статистиках модем обнаруживал низкочастотные помехи. Поскольку помехи обнаруживаются не всякий раз, их уровень низкий, на границе обнаружения. В такой ситуации запрет работы фильтра часто помогает.

Что касается остального, то скорость всё равно придётся ограничивать. Если Вы не хотите ставить "жёсткое ограничение" с помощью команды +MS, то используйте "мягкий вариант": S120 и S202.3=1. При "мягком ограничении" модем сможет поднять скорость соединения, если сложатся условия.

Строка:

S91=18 S210.7=1 S55.4=1 S17=64 S202.3=1 S120=9
