| 单词 | register |
| 释义 | register A high-speed buffer, or region of memory, that is used to store digits or characters for a specific purpose. In telecommunications, a Central Office (CO) switch register stores dialed digits until the caller completes dialing the outgoing telephone number. At that point, the switch analyzes the number and determines how to process the call. If the call is within the CO switch’s domain and the target telephone is available, the switch rings that phone and connects the call. If the call is a local call intended for a destination telephone outside the CO switch’s domain, it will hand the call off to another CO switch within the local calling area, or perhaps to an intermediate tandem switch. A tandem switch is always involved if the call is long distance or international in nature. See also buffer and shift register. |
