Abstract:
A method of constructing a channel rearrange equipment, comprising steps of:providing first and second sets of elements, each set of elements including:a high speed transmission line interface unit responsible for signal input-output interface with a set of sending and receiving high speed transmission lines, said signal input-output interface being duplicated a west and east side ports;a low speed transmission line interface unit responsible for signal input-output with a set of sending and receiving low speed transmission lines; anda switching unit for switching between the high speed signals transmitted on the high speed transmission lines and the low speed signals transmitted on the low speed transmission lines; andinterconnecting said first and second sets of elements with each other such that the west and east side ports of said high speed transmission line interface unit of said first set of elements are used as a working high speed transmission line and the west and east side ports of said high speed transmission line interface unit of said second set of elements are used as a protection high speed transmission line.
