500 NT8D14 Universal Trunk card
The Universal Trunk Card is equipped with a microprocessor which
controls card operation. The microprocessor also provides the
communication function for the card.
The Universal Trunk Card communicates with the Controller Card through
a serial communication link. Features provided through the link include:
•
card-identification
• self-test status reporting
• status reporting to the Controller Card
•
maintenance diagnostics
Card LAN interface
Maintenance data is exchanged with the common equipment CPU over a
dedicated asynchronous serial network called the Card LAN link.
Maintenance data is exchanged with the common equipment CPU over a

LAN link is described in
“SDI function” (page 998) .

Signaling and control
The signaling and control portion of the Universal Trunk card works with
the CPU to operate the card hardware. The card receives messages from
the CPU over a signaling channel in the DS-30X loop and returns status
information to the CPU over the same channel. The signaling and control
portion of the card provides the means for analog loop terminations to
establish, supervise, and take down call connections.
The signaling and control portion of the card provides circuits that
establish, supervise, and take down call connections. These circuits work
with the system CPU to operate trunk interface circuits during calls. The
circuits receive outgoing call signaling messages from the CPU and return
incoming call status information over the DS-30X network loop.
