L5113:LAPD_RX_LONGFRM_ERR
The L3 messages are sent through L2 to L1. Then L1 sends the messages in the form of physical frames. If an error occurs when L1 receives a long frame, this frame is discarded, and this counter is incremented by 1.
If the physical uplink is disrupted, the measurement result cannot be sent to the BSC, and the value of this counter does not increase.
Integer number or integer.
This counter is measured when the BTS L1 erroneously receives an LAPD Link long frame.
