100

is the primary means of delivering message traffic to the Fleet.
What is Fleet Multi-channel Broadcast System

100

was developed to allow multiple baseband subsystems, or users, to simultaneously use a single 25 or 5 kilohertz (kHz) satellite channel.
What is UHF DAMA subsystem

100

is the measure and controls taken to deny unauthorized person(s) information derived from telecommunications and ensure the authenticity of such telecommunications.
What is COMMUNICATIONS SECURITY (COMSEC)

100

The three methods of operating circuits
What is simplex, duplex and semi-duplex,

100

Are short, concise messages between communication personnel. Such messages have the force of official communications and will be accorded prompt attention.
What is a Service messages

200

is a highly flexible system providing global broadcast service to the Fleet via four major communications areas.
What is MULCAST System

200

System provides worldwide coverage with high-capacity, anti-jam (AJ), real-time command and control communications links with full-duplex communications capability via SHF Satellites, between designated mobile units and Defense Satellite Communications System (DSCS) shore sites.
What is Super High Frequency Satellite Communications (SATCOM)

200

consists of aids and hardware which secure telecommunications or ensure the authenticity of such communications.
What is COMSEC material

200

circuits are a combination of the simplex and duplex modes. All stations except the NECOS transmit and receive on the same frequency.
What is Semi-duplex

200

May delegate release authority for service messages down to the communications watch supervisor.
What is Communications officers

300

A maximum of sixteen channels of information are combined to form the
What is multi-channel broadcast

300

provides the services with interoperable and survivable SATCOM.
What is Extremely High Frequency system

300

Maintain a master list of individuals having routine access to classified communications spaces. At a minimum this list should show the name and rank of authorized personnel, level of clearance and access authorized, as well as their specific function/spaces, e.g., fleet center, tech control, message center.
What is Access And Visitors Control

300

describes a circuit designed to transmit and receive simultaneously. In such operations each station transmits on a different frequency and both stations transmit concurrently.
What is Duplex

300

Commonly referred to as "Q" and "Z" signals, are found in ACP 131 and its supplement, and provide a concise unclassified code designed for use by communications personnel to exchange information related to establishing communications or message handling.
What is Operating signals

400

Is a survivable communications link during trans-attack and post-attack phases of conflict. It enables the President and the Secretary of Defense to directly contact submarines, bombers and missile platforms protecting our national security through strategic nuclear deterrence
What is TACAMO

400

consisting of Fleet Satellites (FLTSAT'S), and Leased Satellites (LEASAT'S), provides worldwide communication connectivity with all naval ships and submarines, certain land and air platforms, and fixed shore sites.
What is Ultra High Frequency (UHF)

400

is a real-time procedure which brings to the immediate attention of circuit operators the fact that an EEFI (Essential Elements of Friendly Information) disclosure has (or may have) occurred.
What is BEADWINDOW

400

are dedicated circuits which provide communications between commanders afloat and those ashore. These terminations require allocation of limited NCTAMS/NAVCOMTELSTA assets.
What is Full Period Terminations

400

When an originating or relay station detects an error in a transmission, that station must send a correction by using
What is a concise service or else ZDG/ZEL procedures.

500

Aircraft operations requires dedicated transmission of all ground-to-air traffic using the broadcast method.
What is the nature of USW patrol

500

Apt to provide the best current information on the latest procedures for communicating in this dynamic environment.
What is NTP 2, CIB/CIA'S

500

These plans outline procedures to reduce the amount of classified material held, and realign storage so that should emergency destruction be required, it can be accomplished in an expeditious manner.
What is Emergency destruction plans

500

circuits are encrypted, Frequency Shift Keying (FSK)/Phase Shift Keying (PSK) PC nets which permit afloat units to transmit record communications for delivery ashore.
What is Primary Ship/Shore Circuits

500

is a PROFORMA message designed for fleet broadcast subscribers to request the rerun (ZDK) of messages missed or received garbled on any fleet broadcast.
What is Broadcast Screen Request (BSR)
