爱立信2202机柜采用两传输级联至此机架，在BSC监控端出现TS 1B3故障。基站端只出现A0 TS0－0 EC1：3，此描述为
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.
此小区为只开一个EDGE载波。
