Glossary

ADSL

Asymmetric Digital Subscriber Line.
Commonly referred to as broadband, this is a type
of broadband used to connect to the internet. ADSL allows more data to be sent over
existing copper telephone

lines, when compared to traditional modem lines. A special
filter, called a micro filter, is installed on a subscriber's telephone line to allow both
ADSL and regular voice (telephone) services to be used at the same time.

Aux

Auxiliary Lines are Multi
Lines that provide a single phone number across a group of
between two and 200 lines. They let incoming calls be routed to the first available line or
be routed cyclically using all the lines in the group in turn. It supports more than one
incoming or outg
oing call simultaneously and offers a residential or business telephone
directory listing.

Bearer

Bearer is what the line and equipment an ISDN30e is delivered over.

BIS

‘Bring Into Service’ is the final step on an ISDN30e New Provide order where
Openre
ach will bring the circuit into service. This is actioned after the installation work
has been completed.

Block
Terminal

Block Terminals are used for security to run an alarm line through. These are normally
installed by Openreach though are not maintained by Openreach. An NTE should be
fitted before the Block Terminal as this is a demarcation point for testing.

Care Level

Agreement

Care Level Agreements range from 1 to 4 and Openreach aim to respond to faults
within the timescale allocated within the care level.

CDTA

‘Conscious Decision To Appoint’ is an acronym to confirm that the
customer

is aware of
potential charges i
f an engineer attends the site and proves that there is no fault with
the line.

CLIP

‘Calling Line Identity Presentation’ allows the customer to receive and display the calling
party’s line identity (CLI or telephone number) before answering the call. The called
party will only receive this information if the caller has no restricted the s
ending of their
number and if they have subscribed to the CLIP service. Also known as ‘Caller Display’
on PSTN or analogue lines

CLIR

‘Calling Line Id
entity Restriction’ allows a customer

to restrict their calling line identity
(CLI) to not be displayed
at any time. This can also be done on a "per call" basis by
dialling the "1470" prefix before making a call.

Channels

Channels are found on ISDN systems and the amount of channels will indicate the
number of calls that can be made at any one time.

Contact

This is vital for raising any fault. The engineer should ring ahead to the contact and they
should be present when the engineer attends the site to confirm that the line is working.
It is important that the contact is always someone on site.

CPE

‘Customer Premises Equipment’ is equipment belonging to the
customer

on site (e.g.
PBX, Telephone, Fax Machine etc.).

CPS

‘Carrier Pre Select’ is a way of routing calls on behalf of
a

customer

over a particular
communications provider. This is done at the

exchange, so no codes are needed to be
dialled.

DDI

‘Direct Dial Inward’ is an extension on an ISDN system. These are physical lines
internally after the main socket.

Demarcation
Point

Demarcation Point is where Openreach will maintain the line to. This is typically an NTE
or NTTP socket on the wall. This is where testing should be performed before raising a
line fault.

DP

‘Distribution Point’ is the point at which single telephone
lines are taken from a bundle to
a premise.

Driver
Circuits

When there are multiple orders for the same
customer

or premise (regardless of product
type PSTN, ISDN2, ISDN30), the first order that is built on the Openreach system
become what is commonly kno
wn as a driver circuit/lead order.



If any line plant work is required to be completed to provide the services, all the work is
completed and associated charges are applied to the driver circuit/lead order and as the
order progresses all other secondary o
rders for the
customer
/premise would also
progress in conjunction with the driver circuit/lead order. However, should the driver
circuit/lead order be cancelled all associated work and charges would transfer onto the
secondary order.

Also should any delay
s be encountered with the driver circuit/lead order, it would also
affect the progress of the secondary orders and will continue to be delayed until it has
been resolved on the driver circuit/lead order.

Finally, if the driver circuit/lead order is with a
nother service provider the
customer

would
need to
contact the concerned service provider as
we

are unable to obtain any
order information due to the Data Protection Act.

Dual Tone

Dual Tone is a line that supports both Pulse and Tone dialling

ECCs

‘Exce
ss Construction Charges’ are raised when additional infrastructure is required to
provide new or extended service at a customer’s site.

ERT

‘Estimated Response Time’ is when Openreach schedule to attend a site to attempt to
clear a fault.

ESF

‘Exchange

Service Features’ are features added to the line at the exchange to provid
e
additional services for a customer
. An example of this is Call Divert CLI Presentation.

Fault
Location

‘Fault Location’ is an indicator as to where a potential fault may lie. Di
fferent engineers
deal with different locations on a fault.

ISDN2
Digital
Standard

Integrated Services Digital Network (ISDN) is a set of communication standards for
simultaneous digital transmission of voice, video, data, and other network services over

the traditional circuits of the public switched telephone network. ISDN2 Digital Standard
can have a maximum of two channels and up to nine multiple subscriber numbers.

ISDN2
Digital
System

Integrated Services Digital Network (ISDN) is a set of communic
ation standards for
simultaneous digital transmission of voice, video, data, and other network services over
the traditional circuits of the public switched telephone network. ISDN2 Digital Systems
have a maximum of 5 slots (including the main number) for
DDIs and SNDDIs. The
ranges can be anything from 10 to 2000 if needed in each slot and the 5 slots can be
any variation of DDIs or SNDDIs.

ISDN30

Integrated Services Digital Network (ISDN) 30 and ISDN2 are almost identical
functionality wise. ISDN2e is su
pplied in multiples of two lines which can be expanded
further in multiples of two, but each expansion requires an engineer’s visit and system
programming (2 weeks lead time).

If you require 6 lines or less on your telephone system and it is likely that t
his figure will
not increase, then ISDN2e will usually suffice. However, for larger organisations or, if
you intend to expand your telecoms operation in the future then the correct solution is
probably an ISDN30e as these can be installed with minimum of 8

channels and a
maximum of 30 which is a significant increase over the ISDN2. ISDN30 have a
maximum of 5 slots (including the main number) for DDIs and SNDDIs. The ranges can
be anything from 10 to 2000 if needed in each slot, and the 5 slots can be any va
riation
of DDIs or SNDDIs.

Jumpers

A Jumper is a piece of equipment located at the exchange which connects the line at
the MDF.

KCI

‘Keeping the Customer Informed’ are alerts sent from Openreach to keep us informed
on the progress of the order and its
updates.

Lead Fault

When a common fault has been identified, a Lead Fault is then placed. This is where all
the current updates are added to regarding the fault's progress.

Line Test

A line test can only be performed on PSTN lines. A line test is an indi
cator to a fault and
is not 100% accurate. Initial line tests have to be performed before you can progress a
fault.

Line Plant

‘Line Plant’ is information used regarding infrastructure that is required to provide
service. This can range from cabling and
ducting to pole work. This may involve Excess
Construction Charges (ECCs).

LLU

‘Local Loop Unbundling’ is the process where the incumbent operator (BT Openreach)
makes its local network (the copper cables that run from customers premises to the
telephone
exchange) available to other companies. Operators are then able to install
their own equipment allowing them to provide their own services direct to their
customers.

Local Loop

‘Local Loop’ is the part of the public switched telephone network (PSTN) which

connects
subscribers' equipment with the nearest local telephone exchange. Until recently this
was affected exclusively by means of a copper wire. Radio in the Local Loop (RITTL)
-

sometimes known as a Radio Tail
-

is employed as an alternative in some ca
ses.

Main Billing
Number

The Main Billing Number is applicable on ISDN circuits when you may have several
numbers in use. A fault should be raised on the main billing number, and not a DDI.

MBORC

‘Matters Beyond Our Reasonable Control’ is declared when conditions such as the
weather impact on Openreach and their ability to complete provisioning and fault
activities, and are based on geographical areas.

MDF

The Main Distribution Frame connects eq
uipment from inside the exchange to outside
lines.

NFF

‘No Fault Found’ is a term used by Openreach engineers if they have proven that there
is no fault on the line.

NTE

‘Network Termination Equipment’ is fitted by Openreach for analogue (PSTN) lines a
nd
is the demarcation point. This is typically a white "telephone" socket on the wall.

NTTP

Network Testing Terminating Point is the demarcation point for ISDN circuits. These are
boxes fitted to the wall and you will see one box for every two channels.

PBX

A Private Branch Exchange (PBX) is an onsite telephone exchange that serves an
office or building, where the lines though to extensions. A PBX is typically used for multi
-
analogue lines or with SIP Trunks.

PDQ
Machines

A Process Data Quickly Machines is a device that is used to process credit/debit card
transactions. The system is connected to a central location; bank, server or financial
institution, which will automatically authorise and make payment to the retailer fo
r the
goods purchased by the customer.

Presentation
Number

Presentation Number (PN) is a service that allows
customer
s to specify an alternative
telephone number for the CLI on outgoing calls. When the
customer

calls out the
recipient will see the Presen
tation Number and not the actual line number on any Caller
Display equipment they may have, or where they use the 1471 Call Return service the
Presentation Number will be the number stored.

It is important to note that PN is not available on ISDN2 Digital

Standard, and if you
would like this feature, you would need to convert the line to ISDN2 Digital System.
There are many uses for PNs, but utilizing different numbers so return calls are routed
correctly within an organization is a sizeable benefit.

PONR

‘Point Of No Return’ is when a fault has been issued to an engineer and no further
amendments will be able to be made at this stage.

PSTN

‘Public Switched Telephone Network’ is the world's collection of interconnected voice
-
oriented public telephone net
works, both commercial and/or government owned. It's
also referred to as the Plain Old Telephone Service (POTS) or, more commonly, as
Analogue lines.

It is now almost entirely digital in technology except for the final link from the Digital
Local Exchange

(DLE) to the
customer
. It is also used for the transmission of ADSL and
other data services (e.g. Process Data Quickly (PDQ) Machines) and alarm lines.

RBD

‘Required By Date’ is normally an ERT given for contractors for further work that is
required. A
RBD does not always guarantee the fault to be cleared on this date as it
depends on the work involved.

RWT

‘Right When Tests’ is a fault code that is normally used to advise that an engineer has
attended the site and no fault has been found with the line
.

S Bus
Extension

An S Bus Extension is an extension cable from an ISDN2 circuit that can be up to 800
metres long.

Second
Stage
Repair

‘Second Stage Repair’ is when further work is required though is to be completed by
another team. Second Stage repairs are involved to look at the paperwork and assign
ERTs.

SLA

‘Service Level Agreement’ is reflected by the Care Level Agreement and the C
ustomer
Service Plan. Once this timescale has been exceeded, it can be escalated.

Slamming

‘Slamming’ is a term used to describe a situation where a provider attempts to transfer
the customer without that customer's consent.

System
Maintainer

Openreach
only maintain lines and circuits to the point of entry into a premise. Faults
that involve internal wiring and/or equipment/systems should be resolved by a system
maintainer.

T&D

‘Tested & Demonstrated’ is when the engineer who has attended the site has
tested
and demonstrated that the line is working before closing the job.

Temporary
Call Divert

This is a facility which is provided free of charges on an open fault until the fault has
been resolved. The divert cannot be changed once the fault has is in
a PONR state.

TRC

‘Time Related Charges’ are the charges that are passed on for Openreach's attendance
to the site if there is no fault found with the line.
