求翻译：从通信机械室至SER室敷设2根光缆，其中一根12芯光缆供CSM使用；一根24芯光缆供CTC系统使用（CTC车站站间通信12芯，全景显示通道12芯）是什么意思？

Communication mechanical room to the ser Room laying two fiber optic cable, a 12 core fiber optic cable for csm; a 24 core fiber optic cable for the the ctc system (a ctc communication between the stations of the 12 core, panoramic display channel 12 core)

Mechanical room from the communications room to SER laying 2 fiber optic cable, one end of one of the 12 core fiber optic cable for CSM use; one 24-Pin fiber optic cable for CTC CTC station system use (communication between site 12 and panoramic display channel 12 core)

Lays 2 optical cables from the correspondence equipment room to the SER room, 12 core optical cable uses for CSM; A 24 core optical cable (CTC station interstation corresponds 12 cores for the CTC system use, panoramic indication channel 12 cores)

2 optical cable communication machine room to room SER laid, which used a 12-core optical fiber cable for CSM; a 24-core optical fiber cable for use by CTC systems (communication between CTC Station 12-core, panoramic display channel 12 cores)
