Definitions

AC SUPERVISION.
Indication of off-hook by presence or absence of tones.

BUSY HOUR.
That hour in a 24-hour period during which the traffic load offered to a switch is at a maximum.

Capability to forward a call via an operator.

CALL TRANSFER.
Capability of having calls transferred automatically.

CIRCUIT BOARD.
Printed circuit card usually capable of being unplugged.

CIRCUIT CARD.
Printed circuit boards or printed circuit cards.

CLASSMARKS.
Termination identifier for use, service features, security, classification, restrictions, signaling, and supervision.

COMMON BATTERY.
Battery which serves as central source of energy for many circuits.

COMPRESSED DIALING.
Ability to dial a 2-digit number to reach another subscriber.

DC SUPERVISION.
Indication of off-hook by presence or absence of DC voltage.

DIRECT ACCESS SERVICE.
Capability to call a predesignated subscriber by going off-hook.

E&M.
Designation of signaling leads at a switch. E for recEiving (Ear). M for transMitting (Mouth).

ERLANG.
Unit of telephone traffic numerically equal to percentage of occupancy of a trunk.

EXTRASWITCH TRUNK GROUP.
Interconnects an AN/TTC-39 to a non-AN/TTC-39 switch.

FRAME RATE.
The basic channel rate at which the switch operates. Either 16 or 32 kbs.

GLARE.
The condition that exists when two switches simultaneously attempt to use the same trunk to access each other.

GRADE-OF-SERVICE.
Probability of a call being blocked.

HOLDING TIME.
Elapsed time of a telephone call.

INTERFACE.
Consists of the electrical and mechanical connections, and the procedures necessary to make these connections functional.

INTERSWITCH TRUNK GROUP.
Interconnects two AN/TTC-39s or AN/TTC-39 and AN/TYC-39.

KEY.
A sequence of random binary digits used to set up and/or periodically change the existing electronic key settings in COMSEC equipment.

LINE.
Transmission circuit.

LINE DRIVER INTERFACE.
Provides logic level conversion from TTL to bipolar voltages.

LOCAL BATTERY.
Source of talking power located at subscriber's telephone.

LOOP.
A circuit from a switch to the subscriber.

LOOPBACK.
Ability to connect transmit and receive portions at a termination.

Having dimensions or characteristics which allow expansion or contraction in whole units.

OBJECTIVE SYSTEM.
All-digital communication system of the future.

OFF-HOOK SERVICE.
Automatic establishment of a connection between specified subscribers by lifting handset.

ORIGINATING OFFICE CONTROL.
Routing method where originating office retains control of directing a call.

PRINTED CIRCUIT BOARD.
Circuit card usually designed to be easily replaceable with boards with different functions. They are called PCB.

QUEUE PROCESSING.
Element of software design. Events are queued as they occur and then processed.

RAMIFICATION MESSAGE.
A message to the operator showing data base discrepancies and possible results. It also shows when an action cannot be taken.

RECONFIGURATION.
(1) Changes made to a circuit switching network. (2) Changes made to a switch (number of matrices, cards, modules and other equipment.)

RINGDOWN.
Method of signaling where one incoming signal is activated by alternating (ringing) current over the circuit.

SPILL FORWARD CONTROL.
Transfer routing control on a call to a succeeding switch by sending forward the complete telephone address.

TECHNICAL CONTROL (TECH CONTROL).
Central facilities used for testing, patching, troubleshooting, circuit conducting, status reporting, and technical management.

TERMINATIONS.
The connection of a line to a terminal, a switch, a distribution frame or a matrix.

TRUNK.
Single or multichannel communication patch between switches or switching centers.

TRUNK GROUP.
Trunks which have identical characteristics -destination, signaling, and traffic route.

TRUNK GROUP CLUSTER.
Set of trunks with different transmission characteristics (including analog and digital types) with the same destination.

VALIDATION.
The checking of a data entry to determine its acceptability, size, and range.

WINK START.
A timed off-hook signal indicating readiness to receive pulses.
