應用功能 安裝環境 20-20 交換機 到最嚴格的 從最嚴苛的 美國 FAA 選擇20-20來作為空中交通 控制的語音通信系統, 系統的要求為 每一年停機時間需要少於3秒鐘 Gazprom為蘇聯最大的天然瓦斯供應商, 選用 20-20 交換機系統來提供他們遍及 西伯利亞的專用通信網路 Teltronics has built communications systems and networks for a wide variety of customers. Our systems have been installed in some of the most demanding environments. For Gazprom, the largest natural gas provider in the world, we built a communications system of over 180 switches across Russia. Some of the systems had to be installed 20 to 30 underground to get beneath the permafrost in Siberia. The FAA selected the 20-20 switch for the air traffic control voice communications system which requires 99.999% availability, allowing no more than 3 seconds of downtime per year. <Mouse Click>

20-20 IXP 精緻的造型滿足您商用通信的各項需求 硬體介面 系統軟體 系統的使用以及維護 各式應用功能 Rearrange this agenda to follow the topics in the order you will discuss them The 20-20 IXP is engineered to streamline your business communications. Today we’ll be discussing the following features of the switch <Mouse Click>

20-20 IXP 的設計 機櫃卡槽均為通用介面設計 所有的介面卡片均可以安裝在 任何的機櫃之內 機櫃與機櫃之間可以至多距 離100公尺 所有的介面卡片均可以安裝在 任何的機櫃之內 每一機櫃 256 Port 機櫃與機櫃之間可以至多距 離100公尺 The 20-20 IXP uses a universal telephony shelf design. The system shown here has space for 16 cards with a total of 256 ports available in the shelf. <Mouse Click> Some systems require you to have a shelf for each type of card. With the 20-20 any card fits in any shelf -whether it’s a line card, trunk card or common service unit (such as a modem). The 20-20 IXP gives you flexibility in your facilities planning. If you decide to purchase more than one shelf, they can be located up to 100 meters (300 feet) apart. A big Teltronics advantage is that we have redundancy available on all systems, regardless of size. Many manufacturers only offer redundancy on large systems. You can have 100% redundant common control and power supplies, to ensure your business communications are always up. ADVANTAGE 所有的系統均可升級至雙套備援的能力 許多廠家只在較大型的系統才提供雙套備援的能力

20-20 IXP 的高擴充性 由初始的小容量可一直擴充至大容量的系統 - 過程方便且符合經濟效益 模組化的硬體架構 每一機櫃 256 埠 可擴充最多至10,000 埠 全部通話無阻塞 (Non-blocking) The 20-20 IXP is modular system, you can start with as few as 256 ports and grow up to 10,000 ports. Expanding is easy and cost-effective. Our hardware architecture grows with you. Many systems have to be re-engineered to add memory or processor power, but Teltronics anticipated system expansion and designed the 20-20 to accommodate growth <Mouse Click> While some switches require cumbersome traffic planning to decrease port blockage, the 20-20 IXP is designed to be non-blocking, allowing all ports to be used at the same time. <Mouse Click> ADVANTAGE “真正通話無阻塞” 的系統架構, 允許所有的迴路可以同使被使用

模組式的軟體架構 “建構式方塊” 模組化的軟體架構達到提供客戶靈活性與穩定性的要求 完美的增加功能方式 使用Software key 來控制 立即可以升級完成 One of the important advantages of the 20-20 IXP is the modular software architecture. Think of our features as building blocks that can easily be stacked on top of each other. When you purchase this switch, all of our features are already in the software. The features are software key controlled. So if you want to add another feature to your system, enabling it is simple and easy. With many competitive systems, you need to reload the complete software package and then test for interworking. With the 20-20 IXP, all of the features are fully tested and also tested for internetworking. <Mouse Click>

通訊的操作管理 模組化的軟體架構提供穩定性的要求 256 組不同的服務等級 撥號控制等級 服務功能等級 通話路徑等級 -只能接聽 -需要輸入授權碼 -一般撥號 撥號控制等級 服務功能等級 -呼叫等待 -廣播呼叫 -通話保留 -所有外撥的路徑 通話路徑等級 -只能內線通話 -外撥限制 The 20-20 IXP has 256 distinct classes of service available. You define the classes of service by selecting elements from the dial control, feature and routing classes. For example, you might want your executive users to have a special calling profile. You would use the class of service to define this profile. Within each of the classes there are 64 elements from which to choose. <Mouse Click> Just to give you an example of some of the elements -- shown on the screen are selected elements from the dial control class (authorization required, normal dialing, no origination) <Mouse Click> Feature class (call waiting, paging, call holding) and routing class (internal only, all outgoing routes, no outgoing) 由分機號碼以及使用者的權利 來定義可以使用的功能
