Glossary of Telecom Terms

26 Bit Wiegand Format - The industry standard data output of access control card readers.

tomatic C

ll D

stributor - A device for distributing many calls uniformly among a group of agents

or operators. The ACD pays attention to real time traffic load and other factors like which agent has been the

busiest or idle the longest, to evenly distribute call traffic to the agents (also see

UCD).

ericans with D

sabilities A

t - Legislation passed in 1992 to assure equal building access for

the disabled, which also included equal access to emergency assistance in the event of an elevator emergency.

AGC - Automatic Gain Control - Electronic circuit which automatically increases the volume when someone

is speaking quietly and drops the volume when someone is speaking loudly, to keep the transmitted signal

onstant.

A-Lead - Control leads that come from 1A2 key telephone to operate features like flashing of lights to

ndicate a busy, holding or ringing line.

Analog Single Line Station - An extension port on a PABX/KSU that will allow a standard household type

hone to interface with the system. (

OTS

)

ATA -Analog Telephone Adapter - Analog Telephone Adapter, allows user to connect analog telecom

devices to their LAN, WAN or internet (See

FXO, FXS).

AWG -American Wire Gauge - The higher the AWG number the thinner the wire.

BOM - Beginning of Message - A short electrical pulse provided by a digital announcer when used in

certain 4 wire

E & M modes. The pulse alerts the PABX that the Beginning of a Message is coming.

Butt Set: a sophisticated, one piece, telephone used by technicians to diagnose telephone lines or equipment.

Call Progress Detection (Analysis) - A feature of some terminal devices that allows the Terminal Device

o detect when a call has been answered, so the device can play a recorded announcement to the person that

nswered.

arbon Transmitter (Handset)

The microphone of a telephone handset which uses carbon granules and

a diaphragm. The diaphragm responds to voice and varies the pressure on the granules and hence, their

resistance.

Cat 5E - This is a performance category for 8 conductor twisted pair wire. It defines the maximum data rate

that a cable can handle.

CD Quality - Digital audio utilizing 16 bits of resolution at a sampling rate of 44.1k, which is the same as

audio CD's. Better sounding than other compressed formats such as MP3.

C.O./CO - Central Office - A main telephone office where switching equipment is housed and customer

lines originate. Also contains

Trunk line connections to other Central Offices. A C.O. line is a phone line

coming from the Central Office and terminating at the user’s premise.

Central Station Monitoring - Service provided to monitor security systems and emergency phones 24 hours

a day. Often uses a high speed

DTMF communication format to automatically identify where the call is coming

from.

Centrex - A name for an umbrella service offering of the local telephone company. Customers lease a portion

of the Central Office switch to create a centralized point of control and routing. In concept, Centrex is providing

similar features to a

PABX. In some areas, also known as Centron, Cenpac, or Plexar.

CMOS - “Complimentary, Metal Oxide Semiconductor” - When used for the image sensor in video

cameras it allows a wide operating temperature range with high reliability.

CNG -CalliNG - 1100 Hz .5 second tone generated every 3.5 seconds by fax machines.

Contact Closure - Contacts that when “closed” connect a pair of wires together and disconnects the wires

when “open”. A doorbell button is a simple example of a momentary contact closure.

CPC - Calling Party Control (Disconnect Supervision) - A short break in the line current in the called

party’s phone line when the calling party hangs up. Not available on most

PABX’s.

Demarcation Point (box) - Typically the point at which the phone line enters the building. The telephone

company is responsible for all wiring up to this point.

DHCP - Dynamic Host Configuration Protocal

DISA - Direct Inward System Access

DID -Direct Inward Dialing is a feature allowing callers to directly reach a PABX extension without an

operator’s assistance.

Distinctive Ringing (also known as ringmate, custom ring, identifying ring master) - Different

patterns of ringing that allow a user to identify the source of the call, outside, or inside (intercom) or who the

call is for. Usually two burst or three burst with different durations.

DSL - Digital Subscriber Line - High Speed digital data on standard two conductor voice grade telephone

wiring. Allows high speed Internet access and telephone calls to take place simultaneously.

DSL Filter - Filter designed for DSL lines that prevents the normal telephones from hearing the high speed

digital data and interfering with the data.

DTMF - Dual Tone Multi-Frequency (Touch Tone) - Audible tones which conform to North American

Telephone Standards. These are generated by push-button telephones to dial telephone numbers, as well as to

provide control or data input to voice processing systems. Especially significant in the operation of Viking

automated attendants and fax/data line sharing devices.

Memory (See Non-Volatile E

Memory)

& M Control /4 Wire E & M

An equipment signaling system usually used in

ABX

pplications with

digital announcer. This interface control scheme is standard equipment on most Viking announcers.

Earth Ground - A wire conductor that terminates in the earth for electrical purposes.

deral C

mmunications C

mmission

Facility Code - A 3 digit number that each Proxy Card contains in order to provide greater security.

Usually the cards used at a given building all have the same facility code.

iber Optic Modems

Devices to extend a telephone link on fiber optic cable.

FXO - An analog input RJ-11 port just like a POTS trunk input on a PABX or key system. An FXO port

eceives talk battery and ring voltage.

FXS - An analog output RJ-11 just like a station port on a phone system or PABX extension. It provides

Talk Battery, dial tone, and Ring Voltage.

round Start Line

A type of call signaling. In this scheme, when a call is routed to a subscriber, the

hone company will apply a ground signal on the TIP side of the line even before a

ing Signal

s sent.

y detecting this signal, phone systems can immediately determine that the line is about to be in use, and

void call crashing.

Hook Switch Flash or Switch Hook Flash - A signal originated by momentarily depressing the switch

hook on a single line phone. Typically used for accessing

C.O. or PABX features.

Hz - Hertz - Indicates the frequency (number of cycles per second) of alternating current such as Ringing

Voltage

or Touch Tone signals.

ntercept

To stop a telephone call directed to an improper telephone number, and redirect that call to an

perator or recording.

SDN

tegrated S

rvices D

gital N

twork - An emerging international standard that defines

nterfaces for simultaneous voice and data transmission through a single channel over the public network.

ISDN Terminal Adapter - An interface between an ISDN line and a computer. Often these provide 1 or

2 analog

POTS output ports.

KSU - Key Service Unit - A central control cabinet serving many multi-button key telephones. Contains

equipment which enables the user to pick up and hold

PABX or Central Office lines and provide flashing

line, steady, busy, and wink hold signals. Dial intercom service is also an option.

LED - Light Emitting Diode.

Loop Current - (typically 20 to 50 mA) Current that flows from the C.O. when a telecom device goes off

hook.

Loop Start Line - A type of calling signal that relies on a telecom device to allow DC

current to flow when it goes into an off hook condition. The

C.O. or PABX senses this

current and intercepts it as a request for service. Also known as “

POTS”.

Loud Ringing - A tone sent over a paging system that is typically triggered by Ring Voltage or a dry

Contact Closure.

MOH - Music On Hold

Night Ringing - The same as Loud Ringing, but usually disabled during the day or "normal business"

hours.

N.O./N.C. - Normally Open/Normally Closed Contact.

“No KSU” - A phone containing all control functions normally associated with a KSU,

thus not requiring a

KSU.

Non-Volatile E

Memory - Memory that will not be lost from a power failure:

Does not need battery backup.

OPX - Off Premise eXtension - A telephone line from the phone system terminated in

a different building than the phone system.

PABX - Private Automatic Branch eXchange - Phone system used to switch telephones between

extensions and to outside lines. For incoming and outgoing (dial 9) calls.

Page Code - An access code of a

PABX

that allows users to access the paging equipment to voice page.

Page Port - A 600 ohm audio output of a PABX intended to connect to an external paging amplifier.

Page Trigger - A signal provided to an amplifier to automatically switch the amplifiers input or mute

background music during a page. Typically a “dry” Contact Closure, but in some cases can be a 5 volt

DC or 12 volt DC trigger voltage.
