             上交所技術公司地面專線交易接入以SDHSTM-1/MSTP千兆光纖的匯聚方式連接電信或聯通SDH/MSTP網絡,為用戶提供2M(SDH)或2M的倍數(MSTP)帶寬接入。該系統主要用于接入競價撮合平臺、綜合業務平臺、期權業務平臺、港股通平臺、固定收益平臺等交易業務,成為用戶集中報盤的主要通信方式,從而滿足用戶的數據傳輸需求。上交所技術公司分別在陸家嘴證券大廈和外高橋地球站機房建有數據中心,各用戶分別通過電信或聯通的專線連接到交易所這兩個數據中心開展各類業務。
             SDH(Synchronous Digital Hierarchy,同步數字體系)采用的信息結構等級稱為同步傳送模塊STM-N(Synchronous Transport Mode,N=1,4,16,64,256),對應速率為155Mbps、622Mbps、2.5Gbps、10Gbps、40 Gbps。技術公司采用點到多點的連接方式,匯聚接口速率為155Mbps(STM-1),用戶端接口速率固定為2Mbps,帶寬無法平滑升速。目前電信、聯通等運營商的SDH骨干網因設備廠商調整,技術支持力度減少,今后對SDH網絡將維持現狀,不再優化升級。上交所技術公司已不接受SDH線路申請。
             MSTP是基于SDH 的多業務傳送平臺,有效改變了傳統2M固定帶寬的模式,支持動態帶寬管理,可對帶寬進行靈活分配,支持用戶帶寬的平滑升級。MSTP支持多種物理接口,可為用戶提供以太網接入方式。
             SDH接入方式:
             SDH網絡是電信級的高速通信網絡,穩定、可靠且易于安裝,網絡節點分布于全國各地。用戶如有光端機設備,則可直接從光端機上輸出2M線路接入路由器。如無光端機則可以采用HDSL接入,通過轉換器接入路由器。
             MSTP接入方式:
             MSTP接入方式一般通過電信/聯通光端機轉為RJ45接口,直接接入路由器以太網端口。
