Ascend通信公司近日推出的MAX4048和MAX4060两种高密度广域网访问交换机可将高性能数字调制解调器、路由器和远程访问服务器集成为一体。 MAX4048配有一个V.34和两个T1广域网接口及48个Series 56数字调制解调器;而MAX4060配有一个V.35和两个E1 WAN接口及60个Series 56数字调制解调器。MAX4048和4060符合Ascend的HybridAccess4000特性集标准。借助HybridAccess4000,MAX4048和4060利用通道化的T1、E1或ISDN PRI中继接口提供模拟或数字访问服务。每种产品都支持多达48或60条同时访问通道,这些通道可能包括V.34或56kbps模拟、56/64kbps帧中继或ISDN BRI。这使得ISDN或帧中继能够与Ascend的
Ascend Communications recently introduced the MAX4048 and MAX4060 two high-density WAN access switches that combine high-performance digital modems, routers, and remote access servers. The MAX4048 features one V.34 and two T1 WAN interfaces and 48 Series 56 digital modems; and the MAX4060 features one V.35 and two E1 WAN interfaces and 60 Series 56 digital modems. The MAX4048 and 4060 meet Ascend’s HybridAccess 4000 feature set standard. With the HybridAccess 4000, the MAX4048 and 4060 provide analog or digital access services using channelized T1, E1 or ISDN PRI trunk interfaces. Each product supports up to 48 or 60 simultaneous access channels, which may include V.34 or 56 kbps analog, 56/64 kbps Frame Relay, or ISDN BRI. This enables ISDN or Frame Relay to work with Ascend
