Glossary of terms for technical standards.
The following words
				and terms, when used in this section, have the following meanings, unless the
				context clearly indicates otherwise:
ALI-Automatic Location Identification
-A
				  feature which displays a name and address associated with the telephone number
				  from which the call originated to the PSAP on customer premises
				  equipment.
ANI-Automatic Number Identification
-A
				  feature by which the telephone number from which the call originated is
				  forwarded to the compatible customer premises equipment.
APCO-Associated Public Safety Communicate Officers,
				  Inc.
-A not-for-profit organization incorporated to develop and foster
				  the progress of the art of public safety communications whose sole purpose is
				  to promote greater correlation of the communications activities of towns,
				  cities, counties, State and Federal agencies, and represent the agencies before
				  the Federal Communications Commission and other regulatory bodies.
Alternative routing
-A feature of the CPE
				  that allows the 911 calls to be routed to a designated alternate location if
				  the following conditions exist:
(i)
				The 911 service lines to the primary PSAP are busy.
(ii) The primary PSAP closes down for a
				period of time.
Answering position
-An appropriately equipped
				  location within a PSAP that is used to receive incoming 911 calls.
Audible signal
-A sound that indicates an
				  incoming 911 call.
Average busy hour
-The 1-hour period during
				  the day statistically shown over time to be the hour in which the most
				  emergency telephone calls are received.
Called party hold
-A feature where the
				  attendant retains control of the circuit despite the switchhook condition of
				  the originating station. By remaining off-hook or placing the call on hold,
				  control of the circuit is maintained.
Call party trunk hold
-A feature designed to
				  manage multiple calls where the answering point has the capability to place the
				  calls on hold. This feature is required only where CPE is utilized.
Call-progress
-An audible (ringing) or visual
				  (lighted) indication of the 911 call status to the call taker.
Central office transfer-
(i) Manual central office transfer enables
				the PSAP to transfer an incoming call by depressing the switchhook or button on
				compatible customer premises equipment and dialing either a 7-digit or 10-digit
				telephone number or a 2-digit speed calling code.
(ii) Fixed control office transfer enables a
				PSAP attendant to transfer incoming 911 calls to secondary PSAPs by use of a
				single button on compatible customer premises equipment.
Emergency ringback
-A feature that if a 911
				  caller abandons a call, before information necessary to provide aid is
				  received, the PSAP attendant can activate this central office feature and ring
				  the "on-hook" station which originated the call.
Forced disconnect
-A circuit that is
				  automatically disconnected at the central office despite the switchhook
				  condition of the calling party.
Idle circuit tone application
-An audible
				  signal that informs the PSAP attendant of the status of the line being
				  monitored. Two types of tones are applied to a line under the following
				  conditions:
(i) If a call is abandoned
				prior to completion of a report to the PSAP, tone consisting of 60
				interruptions per minute, busy tone, is applied to the line.
(ii) If the PSAP attendant seizes an idle 911
				circuit, or a caller abandons a 911 call before it is answered, a tone
				consisting of 120 interruptions per minute, reorder tone, is applied to the
				line.
Immediate/splash ringing
-A feature whereby
				  incoming 911 calls are automatically directed to the first available answering
				  position. This allows the caller access to the first available operator and
				  prevents in most cases a busy signal or call hold. Incoming calls may be
				  transferred from station to station within a PSAP, or may be transferred from
				  PSAP to PSAP.
Routing profiles
-A set of procedures that
				  details how PSAPs are notified in the event of circuit disruptions so
				  corrective actions can be taken in a timely manner. Network providers should
				  maintain current routing profiles and ensure that disruption of any circuit
				  element which involves 911 trunking is detected within a reasonable amount of
				  time.
Selective routing/transfer
-A feature that
				  routes a 911 call to the predesignated PSAP based upon the identified number of
				  the calling party. Selective transfer provides the PSAP with the ability to
				  transfer an incoming call to another responding agency by depressing a single
				  button labeled with the type of agency; for example, "FIRE," on the associated
				  customer premises equipment.
Switchhook status
-A feature that indicates
				  an audible or visual, or both, signal if the station originating the 911 call
				  returns to an off-hook status.
Tandem trunking
-An arrangement where a
				  telephone line connection has one or more intermediate switching points which
				  are required or permitted before reaching the final destination. This usually
				  occurs on a controlled dial pulse basis.
TDD/TTY
-A telecommunication device for the
				  hearing and speech impaired.
