660 NT8D15 E and M Trunk card
E and M Trunk card contains a microcontroller that controls the internal
operation of the card and the serial communication link to the NT8D01
Controller Card. The microcontroller provides the following functions:
• card-identification
•
self-test
•
control of card operation
• status report to the controller
• maintenance diagnostics

Card LAN
The card LAN provides a serial communication link for transferring
maintenance data and control signals between the trunk card and the SSC
card. The card LAN controls the microcontroller. The following functions
are supported:
• providing card ID/RLS
• reporting self-test status
•
polling from the controller card
•
enabling/disabling of the DS-30X link
