ATM

Several commands are available to display specific Asynchronous Transfer Mode
(ATM) statistics:

:atm debug aal5stats

Displays AAL5 port specific Asynchronous Transfer Mode (ATM) statistics

:atm debug gstats

Displays global ATM statistics

:atm debug portstats

Displays port specific ATM statistics

Below some examples are provided:

ATM OAM

The SpeedTouch™ supports active Operation and Maintenance (F4/F5 OAM),
LoopBack (LB) and Continuity Checks (CC) statistics via following commands:

:atm oam cc send

Sends CC activate/deactivate to connection.

:atm oam ping

Sends ATM loopback cells

Below an example is provided of an ATM OAM ping:
