مشكل drop شدن مودمها در خطهاي E1
سلام
من يك مشكل كوچيك دارم. اگه دوستان لطف كنند راهنمايي كنند ممنون مي شم.
ما دو تا خط E1 داريم با يك AS5300 4E1 120modem مودمهاي 2M هم از نوع Watson5 هستند.
يوزرها هم اكثرا با سرعت خوبي وصل مي شن. سرعت هم خوبه يعني با 4.5 تا 5.3 دانلود ميكنند. ولي معمولا بعد يه دقيقه مودمها drop ميشن يعني يه دفعه ارتباط به اندازه 3 تا 5 پينگ كه timeout بشه، قطع مي شه، يعني هيچ send و receive انجام نمي شه . بعد از اين 4 تا 10 ثانيه دوباره نقل وانتقال با همون كيفيت از سر گرفته مي شه. تقريبا هر دقيقه اين قضيه يكبار تكرار مي شه (كاربر dc نميشه اصلا). كيفيت پهناي باند خوبه و كلا هيچ timeout ي نداره. (از يك روتر ديگر تامين مي شه)
ورژن مودمهاي ميكا : 2.9.5.0
ios version : 12.3.18
فكر مي كنيد مشكل از كجا باشه ؟
