中文摘要 | 「互動式多媒體服務試用系統」為中華電信研究所(以下簡稱本所)自行研發以ADSL為傳輸方式,在市話網路上提供多媒體應用服務的試用系統。目前在傳統的市話網路上可提供的服務一般僅限於語音、傳真等,最多再加上網際網路服務。為因應未來固網開放所帶來的競爭壓力,我們嘗試在傳統的市話網路上提供互動式多媒體的服務。並且以ADSL來提高市話網路頻寬以達成提供多媒體應用服務的目的。本試用案選擇以本所自行研發之BEX-VPX交換機當作核心基幹,週邊再連接同樣是本所自行研發之AMX設備,試用戶和節目源節點則是透過AMX之LBM面板連上VPX交換機以達成分封交換的目的。本篇文章的目的在於介紹BEX-VPX交換機在此試用系統中所提供之功能與系統之設計。 |
英文摘要 | The “MOD Trial System” is developed by Telecommunication Laboratories(TL), Chunghwa Telecom. The MOD service trial is based upon ADSL technology over PSTN network. This trial system uses the BEX-VPX as a core switch, which is also developed by TL. In this article, we will introduce the design and functions of BEX-VPX that supports the MOD Trial System. In Section 1, we make an introduction about our Trial System and describe the proposed service. The MOD system architecture and scenarios of proposed MOD services are described in Section 2. The architecture and the main functions of BEX-VPX are discussed in Section 3. Later in section 4, we will introduce three new function modules proposed by BEX-VPX that support MOD services, These modules include 1) MCM hardware/software module that is implemented on BLM for the propose of multicasting, 2) mTRAN software module that resides on CC for the propose of controlling the multicast tree, and 3) SNMP Agent software module that is located on CC for the propose of maintenance. In Section 5, we will introduce the maintenance design about BEX-VPX which supports MOD service. Finally, we make a short conclusion for this article. |
