Verifying an Analog Line Card
121
MAC addresses, with the associated port numbers and assigned
extensions.
The ports on an Analog Line Card are usually not auto discovered in
order. The example in
Table 21
shows that port 2 was discovered first
(because it was assigned the lowest extension number), then ports 1, 3,
and 4.
Using Status Lights
You can use the status lights on an Analog Line Card to help verify that
the card has been properly discovered by the NBX system.
When an Analog Line Card is initializing, all four status lights (labelled 1
through 4) blink on and off in unison, approximately once every second.
After an Analog Line Card has been auto discovered, each status light is
off most of the time, but blinks on briefly approximately once every 10
seconds. The order in which the status lights blink is the same as the
order in which the ports were auto discovered. For the example shown in
Table 21
, the lights would blink on in the order 2, 1, 3, 4.
