Nortel Networks 311 Functional description of the NTDK16

512 NT8D02 and NTDK16 Digital Line cards
digital link. Each digital telephone and associated data terminal is assigned
a separate terminal number (TN) in the system database, for a totalof 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
Functional description of the NTDK16
The NTDK16 digital line card is equipped with 48 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 96 addressable ports per card. Refer to Figure 130 "NTDK16 DLC"
(page 513).
The NTDK16 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
The card also provides
•Ability to support Digital sets and the Digital Console M2250
•Provides a serial link (Card LAN) for status report and maintenance.
•Supports loop lengths up to 3500 ft. (1.0 km) using 24 AWG wire.
•Interface between three DS30X loops and 48 TCM lines.
Card interfaces
The digital line card passes voice, data, and signaling over DS-30X loops
and maintenance data over the card LAN link. These interfaces are
discussed in detail in the section "Intelligent Peripheral Equipment" (page
21).
