近期部分基站割接至新BSC后，这些基站的７７２５告警接连不断，可是联系工程师检查却总找不到问题,请问该检查哪些数据呢，我感觉应该找这些基站的共性，可是我对BSC不了解，不知道那些部分和7725告警有关，请高手指点

7725 TRAFFIC CHANNEL ACTIVATION FAILURE

Meaning

The system has blocked the radio time slot because the call control has failed a number of times in the activation of a radio channel.

Supplementary information fields

1 Type of the channel whose TCH activation failed. The channel type can be "TCH", "SDCCH", "Packet Data TCH" or "DTM TCH". The number value "0" indicates "TCH", "1" indicates "SDCCH", "2" indicates "PDTCH" (Packet Data Traffic TCH) and "6" indicates "DTM TCH" (Circuit switched TCH of DTM connection).

Instructions

if the failure type is "PDTCH", the alarm is cancelled automatically by the system, when no more failure indications are observed if the channel type is "TCH", "SDCCH" or "DTM TCH", cancel the alarm with the MML command EOR. Deblock the radio time slot by first aligning the TRX in question with the command ERS and then removing the alignment of the TRX

Cancelling

If the channel type is "TCH", "SDCCH" or "DTM TCH", cancel the alarm with a command before taking the steps described in the INSTRUCTIONS, if the alarm has not been cancelled before. See instructions on base transceiver station alarms handling.
