機場捷運骨幹傳輸系統網管技術簡介 Introduction to the Network Management Technology of TIAA MRT BTN System
骨幹傳輸網路STM-16 SDH塞取多工器。

骨幹傳輸網路又稱核心網路,它由所有用戶共用,負責傳輸骨幹數據。透過光纖傳輸,能夠實現大範圍的數據傳送。這些網路通常採用高速傳輸網路傳輸數據,高速交換設備提供網路路徑。
骨幹傳輸網路為機場捷運之神經中樞,提供捷運供電、號誌等各機電系統訊號傳遞路徑。骨幹傳輸網路包括STM-16 SDH網路、超高速乙太光纖網路,均為複聯雙環,即使單一路徑故障仍可維持正常運作。
機場捷運之骨幹傳輸網路(BTN)系統共有三套網路管理軟體,包括:
1.1353NM控制管理「同步數字體系」設備(Synchronous Digital Hierarchy, SDH),可以對SDH設備進行元件組態、驅動元件、新增/移除元件等,其主要功能計有:使用者管理功能、拓撲圖建立、拓撲圖中的網路元件建立、網路元件的監視與管理、網路元件的警報監視、網路管理工作站(NMS)伺服器的資料庫備份等。
2.1320CT控制管理塞取多工器設備,可對塞取多工器設備進行組態、操作權限設定,驅動元件、新增/移除節點,其主要功能計有:使用者管理測試、網路元件的建立/刪除、警報管理等。
3. Alcatel-Lucent Omnivista可對乙太網路設備進行網路拓樸設定、網路元件告警、新增/移除網路元件,內容包括:使用者管理測試、事件陷阱、組態編輯器、統計及網路維護等。

The Backbone Transmission Network (BTN), also known as the core network, is shared by all users and is responsible for the transmission of backbone data. Through optical fiber transmission, a wide range of data transmission can be realized. These networks typically use high-speed transmission networks to transmit data and high-speed switching devices to provide network paths.
The BTN is the nerve center of the TIAA MRT System. It provides MRT power supply, signaling and other mechanical and electrical system signal transmission paths. The BTN includes the STM-16 SDH network and ultra-high-speed Ethernet fiber network. They are dual-linked with dual-rings and can maintain normal operation even if a single path fails.
The TIAA MRT BTN system has three sets of network management software, including:
1.The 1353NM software controls and manages the Synchronous Digital Hierarchy (SDH) equipment. It can configure components, drive components, add/remove components, etc. on SDH devices. Its main functions include user management functions, creation of topology diagrams, establishment of network elements in topology diagrams, monitoring and management of network elements, alarm monitoring of network elements, and library backup of network management workstation (NMS) servers.
2.The 1320CT software controls the add-drop multiplexing devices. It can configure add-drop multiplexing devices, operate on permission settings, drive components and add/remove nodes. Its main functions include: user management testing, network component creation/deletion, and alarm management.
3.The Alcatel-Lucent Omnivista software can perform network topology configuration, raise network component alarms, and add/remove network elements to Ethernet devices. Its contents include user management test, event trap, configurator, statistics, and network maintenance.
