BTS_Test_ASCI: Add UPLINK FREE / UPLINK BUSY test A VGCS channel is activated. The BSC sends UPLINK FREE message and UPLINK BUSY message. When the UPLINK FREE message is sent, the MS is expected to receive serveral UPLINK FREE messages. Then the UPLINK BUSY message is sent, the MS is expected to receive one UPLINK BUSY message.
