Intelligent Peripheral Equipment module (NT8D37)
The Intelligent Peripheral Equipment module uses the new Peripheral
Equipment cards only and may be used with system options 21A,.21,51,
61,7
1. With an upgrade assembly the Intelligent Peripheral Equipment
modules may be used with all existing systems.
The NT8D37 Intelligent PE module is available in two versions, AC or DC
power. These power supplies provide the voltages to operate the circuit
cards located in the modules.
The NT8D37 module may only be connected to a SuperLoop Network
(NT8DO4AA) circuit card. It houses one Controller card (NT8DOl) and up
to 16 Intelligent Peripheral Equipment circuit cards. The card slots are
numbered from 0 to 15, for a total of 16 PE card slots.
The NT8D37 Intelligent PE module supports 16 PE circuit cards, yielding a
capacity of 256 Integrated Voice/Data (IVD) lines (512 TNs), although a
typical configuration includes a mixture of Digital lines, Analog lines,
Trunks and Digitone Receiver (DTR) circuit cards.
All cable connections to the MDF are made in the rear of the module
through an I/O panel. To serve all 16 PE card slots, 12 PE cables are
required to the MDF.
