60 channel telephone fiber transmission solution

Fiber transmission project requirements:

The 60 channel analog subscriber line of the branch program-controlled switchboard will be transmitted to the business department through optical fiber, and the 60 telephone landlines of the business department will be exchanged free of charge. At the same time, other telephone landlines under the branch switch can be played free of charge.

Optical fiber transmission environment:

First, the branch office and the business department must establish a direct optical cable, and a branch-controlled switching system is established within the branch.

Optical fiber transmission solution:

Introduction of optical fiber transmission scheme:

Branch office: 60 pairs lines from the 60-channel analog subscriber line interface of the branch-controlled switchboard of the branch are respectively connected to the audio patch panel. After reasonable wiring, the 60 pairs lines that are coming out are respectively connected to ZMUX-300 and ZMUX-30 user port (30 pairs of lines connected to ZMUX-300, the remaining 30 pairs are connected to ZMUX-30), and finally the optical port of ZMUX-300 is connected to the optical cable of the direct branch office.

Business department: The optical port of the ZMUX-300 is connected to the optical cable from the branch office, and then the 60 pairs of wires from the ZMUX-300 and ZMUX-30 user ports are respectively connected to the audio patch panel directly to each phone extension.
