法国阿尔卡特SMC360是一种单管同轴通信系统,能双向传输360个话路,距离2500公里(1560英里),在整个线路容许3站可以分出120路.SMC360系统符合CCITT规定的标准,它与类似的多路复用设备如阿尔卡特SMAT一样符合于CCITT标准或贝尔系统的要求,这种系统可以应用在直埋地下或架空的各种单管同轴电缆上.
The French Alcatel SMC360 is a single-pipe coaxial communication system that transmits 360 channels in both directions at a distance of 2,500 km (1,560 miles), allowing 120 stations to be split between 3 stations throughout the line. The SMC360 system complies with CCITT standards, Like similar multiplexing equipment such as the Alcatel SMAT, it conforms to the requirements of the CCITT standard or the Bell system, which can be used on a variety of single-tube coaxial cables buried underground or overhead.
