    Merhaba

    1 saat 29 dakikada bu kadar HATA normal degil.

    492000 paketten, 61000 input error olusmus. ( bu rakam binde biri gecmemeli)
    Ayrica CRC ve carrier transition sayisida oldukca yuksek.

    5300#sh int serial 0:0
    Last clearing of "show interface" counters 01:29:02
    492551 packets input
    ^^^^^^
    61354 input errors, 40846 CRC, 4609 frame, 0 overrun, 0 ignored,
    ^^^^^^^^
    250 carrier transitions
    ^^^^^^^^^^^^^^^^

    Hattin ve aradaki elementlerin kontrol edilmesi lazim ( kablo, topraklama, bozuk bir cihaz...)

    Telekom iki taraftada hattı ölçtü ve sorun yok diyor..
    Neyi olctuler?
    Loopback testi yapildi mi?
    BERT?

    Telcoya bu verilerle geri donmekte yarar var.

    Kolay gelsin

      Merhaba,
      iki nokta arsinda 2Mb leased-line baglantimiz var.
      C5300---------TDM----------NB2902--C1721
      5300 tarfında modem yok.Telekomdan gelen 4 tel kablo direk 5300 ün
      (G.703 E1) portuna giriyor.
      1721 tarafında NB2902 var.1721 tarfi internete 5300 üzerinden cikiyor.
      Sorun iki nokta arsında paket kayıpları oluyor. ping süreleri çok iyi
      ancak ani kayiplar meydana geliyor.
      5300 serial0:0 a CRC ve error paketleri çok fazla geliyor. Telekom
      iki taraftada hattı ölçtü ve sorun yok diyor
      ama bu kayiplari ve error ları önleyemedik.1721 tarafında download
      iyi ancak özellikle web çok yavaş. 5300 tarafında çok hızlı halbuki.
      yardimci olabilir misiniz?
