Check if there is anything wrong with the Abis signaling
link
Abis signaling link failure will also result in the MS network
connection failure.
1) After the BTS start -up, if the Abis signaling link goes wrong,
BSC will be unable to perform logic configuration on BTS, which will
result in the MS network connection failure.
2) If the BTS has obtained the correct logic configuration, when
the Abis signaling link goes wrong, the BTS will turn off the
transmitting signal of the BTRM to which all its sector carrier
frequencies correspond. This will result in the MS network
connection failure.
Through querying the current a larms of the BTS on the OMC
console or BTS local maintenance console, find out if there is an
"Abis signaling link failure" alarm.
Please refer to "2.5
