HDSL
English: HDSL
Chinese: 【计】 高速数字用户专用回线
Examples:
1. "In HDSL (High Bit-rate DSL) and SDSL (Symmetric DSL) the data stream is symmetric; that is, the upstream and downstream rates are the same."
「高速数字用户回路」(hdsl)和「对称数字用户回路」(SDSL)的资料流是对称的,也就是说上行和下行的速率相同。
2. Another problem with HDSL is that it doesn't easily accommodate conventional voice traffic (POTS).
hdsl的另一个问题是它不易适应常规的话音信息流(POTS,即普通的老式电话服务)。
3. Despite their speed, the IDSN, ADSL and HDSL protocols do have limitations.
尽管传输速度快,ISDN、ADSL和hdsl协议也都有局限性。
4. For faster connections, users will have to wait for two protocols: Asymmetric Digital Subscriber Line (ADSL) and High-data-rate Digital Subscriber Line (HDSL).
对于需要更快连接的用户来说,还须等待两个协议:不对称数字用户线(ADSL)和高数据速率数字用户线(hdsl)。
5. HDSL has also found a home in campus settings as a low-cost alternative to running fiber between buildings.
hdsl在校园内也有用武之地,可作为大楼间铺设光缆的低价替代方案。
6. HDSL is a symmetric version of ADSL (meaning data travels at the same speed in each direction) that is primarily oriented toward business applications.
hdsl是对称型的ADSL(就是说数据在双向上以同一速度传输)这主要是面向商业应用。
7. HDSL speeds are 784Kbps in each direction, but unlike ADSL, which will transfer data, voice, and video on the same wire, HDSL can transfer only data.
hdsl在两个方向上的速度均为784Kbps,但与在同一电线上可以传输数据、话音和视频图像的ADSL不一样,hdsl只能传输数据。
8. One drawback to HDSL is that it takes two circuits.
hdsl的一个缺陷是占用一对电路。
9. POTS requires a special modulation and conversion schemes with HDSL, unlike other XDSL variations.
与其它的XDSL变型不一样,用hdsl时,POTS需要特殊的调制和转换方案。
10. With HDSL, they can do it in an hour.
用hdsl,安装只要1小时。
