1.信息插头 传统的语音插头采用RJ11插头,它能满足一般语音传输。随着社会的发展,通信业务范围的不断扩大,要求将用户的语音与非语音信息按统一标准以数字形式将其综合于同一网络,构成综合业务数字网(ISDN)。RJ11已不能满足此要求,RJ45则符合ISDN的技术要求。它既能用作电话出线口,又可作为图像显示及计算机终端。不过,当传输速率超过100MHz时,RJ145就不能满足
1. Information plug The traditional voice plug with RJ11 plug, it can meet the general voice transmission. With the development of society, the scope of communication services is constantly expanding. It requires that users’ voice and non-voice messages be digitally integrated into the same network according to a unified standard to form an Integrated Services Digital Network (ISDN). RJ11 can not meet this requirement, RJ45 is in line with the technical requirements of ISDN. It can be used as a telephone outlet, but also as an image display and computer terminals. However, when the transmission rate exceeds 100MHz, RJ145 can not meet
