7149 atmL2LinkCongested

This event indicates that an Asynchronous Transfer Mode (ATM) signaling link is in the transmit congestion state.

This event occurs when the threshold for the number of MSUs in the transmission or retransmission buffer is exceeded.

Possible causes include:

• link failure
• insufficient links
• traffic bursts
• the onset congestion threshold buffer may be too low to absorb small bursts of traffic
