愛立信2202機柜采用兩傳輸級聯(lián)至此機架，在BSC監(jiān)控端出現(xiàn)TS 1B3故障。基站端只出現(xiàn)A0 TS0－0 EC1：3，此描述為
TRA PCU (REMOTE TRANSCODER PCU COM LOST)
The speech/data frames coming from the BSC to the TS are
missing or corrupt.
This is most likely a fault in the BSC (for example no TRA
allocated, no connection in Group-Switch, and so on) or in the
A-bis transmission path.
此小區(qū)為只開一個EDGE載波。
