Motorola(摩托羅拉)SURFboard SB6121 Cable Modem 介紹(一)

Motorola(摩托羅拉)SURFboard SB6121 Cable Modem 介紹(一):

這台是 Motorola(摩托羅拉)SURFboard SB6121 Cable Modem(電纜調製解調器),電纜調製解調器(簡稱 CM / CableModem)是指就是利用有線電視網絡(CATV)將外網(包括 Internet等)與客戶電腦內網橋接在一起的終端設備。利用 Cable Modem 上網和我們比較熟悉的電話線(ADSL)上網方式比較類似的,記得最早期筆者也是通過 Modem 連接電話線上網,速度祇有 64kB。Cable Modem 是利用 RF Cable 線連接,實現同時雙向傳輸 Internet 上網和有線電視網絡。

Motorola SB6121 是 DOCSIS-3.0 Cable Modem(電纜調製解調器),向後兼容 DOCSIS 1.0、1.1 和 2.0,還支持 IPv4 和 IPv6、高級加密服務以及所有其他 DOCSIS 3.0 標準。作為摩托羅拉 DOCSIS 3.0 超寬帶產品系列的一部分,SB6121 包括一個增強型調諧器,支持高達 1 GHz 的下行輸入,允許運營商增加頻譜以部署新的高價值服務,例如帶寬 - 為其客戶提供需求、商業服務、交互式遊戲和 IPTV。SB6121 具有 10/100/1000Base-T 以太網 (RJ-45) 端口,以及直觀、易於閱讀的狀態 LED。 客戶可以選擇激活雙色 LED,以對綁定通道和 GigE 使用進行視覺驗證。Motorola SB6121 利用 DOCSIS 3.0 技術的力量來綁定多達四個下行通道和四個上行通道。 因此可以提供先進的多媒體服務,每個方向的下載速度高達 172 Mbps。
