NPG 2

Back 12

RTT-A (dedicated) - RTT messages are exchanged between JTIDS/MIDS terminals on this NPG, called addressed RTT, to support fine synchronization.

Front 13

NPG 3

Back 13

RTT-B (Contention) called broadcast performs the same function as NPG 2, but it's timeslots are shared by a group of JUs in which all units can transmit.

The assignment of time slots to a uniquely identified unit for transmission purposes is known as...

Front 29

What is known as the assignment of time slots to a group of units as a pool for transmission purposes?

Back 29

Contention Access

Front 30

In ___________, each unit randomly selects a time slot from the pool during which to transmit.

Back 30

contention access

Front 31

This is an access mode that allows the network capacity of an NPG to be assigned dynamically, based on the projected needs of its participants.

Back 31

Time slot reallocation

Front 32

This is intended to support a fluctuation demand from a varying group of users.

Back 32

TSR

Front 33

____ allows network capacity to be distributed where it is needed, by periodically allocating time slots from a pool to each participant, based on need.

Back 33

TSR

Front 34

How is NPG capacity assigned?

Back 34

It is assigned by specifying time slot blocks and access modes for each participating JU.

Front 35

Network roles are functions assigned to a ___, either by initialization or by operator entry.

Back 35

JU

Front 38

All JU's, except the _____, are referred to as Primary Users (PRUs) if they routinely transmit RTT messages to achieve and maintain fine synchronization with the network.
