| 释义 | hold A voice telephone system (Centrex, KTS, or PBX) feature that enables a user to place an existing call in a suspended state simply by depressing the hold feature button, with a holding indication usually in the form of a blinking light next to the associated line. The user can reconnect the call at any time by depressing the button associated with the line on hold. In a KTS environment, any user can retrieve the held call from any telephone set where the line appears unless the primary user placed the call on exclusive hold, also known as I-hold, which often is initiated by depressing the hold button twice. See also Centrex, KTS, and PBX. 74570c08.qxd 9/11/07 12:22 PM Page 228 |
