h. Error Type 3842: Receive FIFO Overflow error. This error occurs when the circuit pack or
media module detects an overflow of its receive buffers. If it occurs frequently, it may
indicate a LAPD parameter mismatch between the two endpoints of a packet-switched
connection. LAPD should be able to recover from this problem, but it may degrade the
performance of the LAN bus. Maintenance will not start any testing or generate any alarms
in response to this error.
i. Error Type 3843: This error occurs when the Signaling Port LAN Loop-Back test (#939)
