据《Communications News》1992年1月刊报道,美国Cylink公司研制的这种链路安全装置有三种型号,它们是:低速CIDEC—LS,这种设备具有75b/s—128kb/s的速率,能与V.11、V.35、RS—232或RS—449接口,可进行规约透明加密,并能以点对点或多点方式操作。高速CIDEC—HS,这种设备具有56kb/s—7.0Mb/s的速率,能与T_1、T_2、CEPT E1、V.35或RS—449接口,能有效地与综合的T1 CSU一起使用,并还有远程网管的功能。超高速CIDES—VHS,这
According to “Communications News” January 1992, there are three types of link safety devices developed by Cylink Company in the United States: low-speed CIDEC-LS, which has the speed of 75b / s-128kb / s, V.11, V.35, RS-232 or RS-449 interface that can be transparently encrypted and can operate in a point-to-point or multipoint manner. High-speed CIDEC-HS with 56kb / s-7.0Mb / s rate and interface with T_1, T_2, CEPT E1, V.35 or RS-449 for efficient use with the integrated T1 CSU and There are remote network management functions. Super Speed CIDES-VHS, this
