CT-FE1 CSU/DSU 單機型數位式E1高速數據機

CT-FE1 特性
CT-FE1 single data port Frａｃｔｉｏｎal E1 Channel Service Unit/DataService Unit (CSU/DSU). 它是全功能的FE1 DSU 設備，提供高速資料終端設備連接至E1/FE1 網路.
功能包括可軟體升級之DTE 介面,CT-FE1 並支援ITU-TV.35, X.21 或EIA RS-449 DTE 介面. 頻寬分配可由軟體設定並允許最大資料傳輸速率至1948 Kbps.
CT-FE1 提供E1 網路介面,DS0 (64 Kbps)多工通道可連接voice,data 及video DTE. 適用於多網路型態架構下的點對點資料連結.

CT-FT1 提供簡單的前面板設定與操作、local terminal 或SNMP 遠端管理功能.
