28 ATM Cable Interface Processor (ACIP) Installation and Configuration

Examples of ATM Error Messages

•

To display ATM events, use the debug atm events command:

This command displays event changes to the ACIP. Reset, VC configurations, ACIP
configurations, and PLIM failures are displayed.

After you use a debug command, turn off debugging with the no debug command.

Following are additional debug commands specifically related to the ACIP:

•

To display changes in connectivity to the TeraLink system, use the debug cable channel
command.

•

To display changes in subscriber modem status, use the debug cable modem command.

•

To display error messages that are caused by unexpected system behavior or problems
connecting to the Teralink system, use the debug cable error command.

Examples of ATM Error Messages

Following is a list of possible error messages displayed when you enter the debug atm event
command:

Error Message

RESET(ATM2/0): PLIM type is 0, Rate is 0Mbps

Explanation

Displays the PLIM TYPE value returned from the ACIP and the expected associated

rate.

Error Message

AIP_disable(ATM2/0): state=1

Explanation

The DISABLE code to shut the ACIP down has been entered.

Error Message

config(ATM2/0)

Explanation

The current configuration to the ACIP was sent including TXBUFF, RXBUFF,

exception queue length, raw queue length, and rate queue information.

Error Message

AIP_enable(ATM2/0)

Explanation

The ACIP is taken out of shutdown.
