DSL硬件前景光明 DSL硬件正在全面推出,但建立DSL技术的无数标准和协议将会极大地限制它的接受范围。界限将会在最近的讨论划清,这将会导致DSL技术可用性的推迟。 Efficient Networks公司即将推出的称之为Speed Stream的ADSL(asymmetric DSL)设备,利用DMT(Discrete Multi-Tone)技术可用高达6Mbps速率传输下行数据。Speed Stream将以三种版本出现:PCI NIC(595美元)预计在第四季度推出,ISA NIC(595美元)预计在1998一季度推出,外置调制解调器(1195美元),它通过以太网与PC相连,预计在明年第一季度推出。
DSL hardware Bright DSL hardware is in full swing, but the myriad of standards and protocols for establishing DSL technology will greatly limit its acceptance. The boundaries will be set in the recent discussion, which will lead to a delay in the availability of DSL technology. Efficient Networks’ forthcoming ADSL (Asymmetric DSL) device called SpeedStream uses DMT (Discrete Multi-Tone) technology to transmit downstream data at up to 6 Mbps. The Speed Stream will come in three versions: The PCI NIC ($ 595) is expected to be available in the fourth quarter and the ISA NIC ($ 595) is expected to be available in the first quarter of 1998 with an external modem ($ 1,195) connected to the PC via Ethernet , Is expected to be launched in the first quarter of next year.
