Позже вышлю статистику соединения днём.

[Technical Support]

Похоже, Вам не стоит особенно бороться за V.90 - проблем больше, чем преимуществ. Если всё-таки желание побороться есть, то используйте такую строку инициализации:

S91=18 S210.7=1 S202.3=1 +MS=,,,36000,,,21600

Днём наверняка лучше будет на V.34, с такой строкой:

S91=18 S210.7=1 S202.3=1 +MS=11,,,,,,21600

Днём с v-90 действительно плохо, соединяет, но не стабильно, т.е. коннект есть, а данные не идут.

Выкладываю статистику для v-34 с вашей строкой инициализации. Вцелом всё стабильно. Но вдруг что-то стоит изменить?

[Technical Support]

Можно попробовать запретить модему снижать скорость по причине большого процента сбойных кадров данных на приёме ("Forced FB"). Практически все снижения были связаны именно с этим:

FForwards/FBacks/FEQM/Denied. 4/11/0/0
Forced FB/FB after FF/MaxREJ. 10/3/10

При этом средний процент сбойных кадров - "в пределах нормы":

Frames Errors, Rx/Tx......... 561/57 (1,1%/0,5%)

Запрет Forced FB производится добавлением S210.4=1 в строку инициализации. Попробуйте и последите за процентом сбойных кадров и за общей производительностью. Если выяснится, что производительность упала и существенно возрос процент сбойных кадров - вернитесь к прежнему варианту. Не забудьте выключить/включить модем после изменения строки инициализации.

Сбойных больше не стало. Стабильность примерно на том же уровне. Скорость тоже.

[Technical Support]

Кажется, Вы столкнулись с побочным эффектом: удалённый модем начал запрашивать перетренировки. Посмотрите сами: в предыдущей статистике их было две за 43 с лишним минуты соединения. В этих перетренировки случаются существенно чаще:

Time Online.................. 00:04:55
Retrains Issued/Granted/Auto. 0/6/0

Возможно, что речь идёт о случайном совпадении. Чтобы проверить, попробуйте ограничить скорость передачи до 9600, заменив +MS на такую:

+MS=11,,,,,,9600

Если это не скажется на количестве перетренировок, запрашиваемых удалённым модемом, отказывайтесь от S210.4=1.
