426 NT8D02 and NTDK16 Digital Line cards
Functional description of the NT8D02
The digital line card is equipped with 16 identical units. Each unit provides
a multiplexed voice, data, and signaling path to and from digital apparatus
over a 2-wire full duplex 512 kHz time compression multiplexed (TCM)
digital link. Each digital telephone and associated data terminal is
assigned a separate terminal number (TN) in the system database, for a
total of 32 addressable ports per card.
The digital line card contains a microprocessor that provides the following
functions:
•
self-identification
•
self-test
• control of card operation
• status report to the controller
•
maintenance diagnostics
