14.8.5.13 Automatic Laser Shutdown

The automatic laser shutdown (ALS) procedure is supported on both client and trunk interfaces. On the
client interface, ALS is be compliant with ITU-T G.664 (6/99). On the data application and trunk
interface, the switch on and off pulse duration is greater than 60 seconds. The on and off pulse duration
is user-configurable.

14.8.5.14 Jitter

For SONET and SDH signals, the MXP_2.5G_10E card complies to GR-253-CORE, ITU-T G.825, and
ITU-T G.873 for jitter generation, jitter tolerance, and jitter transfer.

14.8.5.15 Lamp Test

The MXP_2.5G_10E card supports a lamp test function that is activated from the ONS 15454 front panel
or through CTC to ensure that all LEDs are functional.

14.8.5.16 Onboard Traffic Generation

The MXP_2.5G_10E card provides internal traffic generation for testing purposes according to
pseudo-random bit sequence (PRBS), SONET/SDH, or ITU-T G.709.
