| 单词 | Megaco (Media gateway control) |
| 释义 | Megaco (Media gateway control) an asynchronous transfer mode (ATM) network. The call control and signaling logic are centralized in the MGC and can include features such as dial tone, collect dialed digits, call hold, call transfer, call forward, and call conference. The MGC signals the MGs, which then execute the feature commands and process the call, performing gateway functions as required to interface the incompatible networks or network elements (NEs). There is a master/slave relationship between the centralized MGC and decentralized MGs, much like that of a traditional PSTN, except that the MGs that execute the features and perform the switching are distributed across the network. See also ATM, call transfer, conference call, dial tone, gateway, H.248, hold, IETF, ITU-T, master/slave, protocol, PSTN, and softswitch. |
