概述根据用户的需要和我厂关于明线铁线高频复用的设想,为了进一步提高明线铁线的复用率,我们在ZZD43型低三路(宽频带)载波机及ZZD44型高三路(也为宽频带)载波机频谱之上,又研制了ZZD45型超三路载波机.这样,在铁线(或有色金属线与电缆)上可以再增加三个话路,一共达到十个话路.三套三路载波机可以端对端叠加开放,也可以以三路为一组,沿途下杆,类似于环路载波机的开放方式.本设备具有各种自动(与人工)的接口,双方向可与国内各种自动
Overview According to the needs of users and our plant on the bright line of high-frequency wire multiplexing reuse ideas, in order to further improve the bright line multiplexing rate, we ZZD43 type low three (broadband) carrier and ZZD44-type high three For the broadband carrier spectrum, and developed ZZD45 type super triple carrier machine, so that in the wire (or non-ferrous metal wire and cable) can be added to the three sessions, a total of ten sessions. Three sets of triple carrier can be superimposed open end to end, but also to a group of three, along the way under the rod, similar to the open loop carrier carrier. The device has a variety of automatic (and manual) interface, the two sides To various domestic and automatic
