Figure 1 shows the faceplate of the ATM Interface Carrier Module with
one OC-12/STM-4 daughter card installed on the left and one
OC-3/STM-1 daughter card installed on the right.
In the figure, the Module is shown on its side; when installed, it stands
vertically in the CoreBuilder 9000 chassis with the LEDs on top.

ATM Interface Module Faceplate
The LED indicators on the left side of the faceplate show the module’s
operational status. The Module Status LED indicator is a general purpose
LED which shows the ATM Interface Module’s status; the two groups of
four port LEDs show the status of individual ports in the daughter cards.
Audience Description
This guide is intended for the system administrator, network equipment
technician, or network manager who is responsible for installing and
managing interface modules designed for operation with network
hardware such as CoreBuilder 9000 ATM switches. It assumes a working
