| 摘要 |
The invention relates to a method for transferring ancillary information, such as channel-associated signalling and alarms in a basic time-divison multiplex system, where ancillary information is transferred in a predetermined timeslot (TS16) of each frame, and where information associated with more than one channel is transferred in at least one timeslot (TS1...TS15, TS17...TS31) of the basic system. To provide a method allowing the ancillary information, particularly signalling and alarms, to be transferred with as high compatibility as possible in a conventional basic multiplex system up to a capacity of 120 speech channels, a superframe (12) having the length of several multiframes (11) is assembled, and at least part of the ancillary information is transferred in said predetermined timeslot (TA16) so that the number of the multiframe is transmitted in addition to said ancillary information, the number indicating with which channel the ancillary information is associated. |
