ITU-T L.340 (06/2023)

عربي | 中文 | English | Español | Français | Русский
地下电信设施的维护
隧道、检修孔和手孔等地下设施会随着时间的推移不断老化。例如,会发生裂缝和漏水现象,这些现象会降低地下设施的安全性和可用性。如果对老化问题视而不见,可能需要进行大规模的修复并采取加固措施,这将增加未来的成本。因此,强烈建议进行定期检查并及时维护。ITU-T L.330建议书对电信基础设施的安全管理做了总体介绍,但每种设施的详细技术和对策则在其它建议书中讨论。ITU-T L.340建议书介绍了ITU-T L.330建议书中定义的地下设施维护的检查程序、技术和对策。
