module's 96-pin DIN connector is engaged into modem Interface Slot 2. The
CDI-70 provides these features:
• A 96-pin DCE (Modem Interface) connection.
• The 'GBEI | J1' LAN interface. See Section D.2.1 for the pinout table for
this single IEEE 802.3ab 1000 Base-T copper-compliant female RJ-45

• The 'GBEI | J1' connector features two Light-Emitting Diodes (LEDs):
o The "Link Status" LED lights amber when the module senses a
stable Ethernet connection.
o "Link Activity" LED flashes green when the module senses
Ethernet data activity.
