ISDN Explained

What is the ISDN?

The ISDN is an evolutionary circuit switched network based
on digital telephony. It uses a common set of interface
standards and allows users to send and receive information
over the network.

ISDN offers end-to-end (caller to receiver) digital
connectivity between Terminal Equipment (TEs), via
Network Terminators (NTs) and digital exchanges, both
private and public.

ISDN Services

ISDN services are the telecommunication services to which
the user has access either at an ISDN interface or a terminal
connected to the ISDN. The diagram below summarises the
services offered:

1-10 429850

Equipment on the ISDN

Each piece of equipment (‘functional group’) on the ISDN
has a label related to the function it performs. The labels are:

Introducing AuroraPlus

ISDN Interfaces

An interface (‘reference point’) is said to exist between each
piece of equipment on the ISDN.

Issue 5 - 04/01 1-11

Trend AuroraPlus User Guide



 Notes



In a typical BRI installation NT1 and NT2 functions are
combined in single NTE (Network Termination Equipment).

ISDN Standards

ISDN is subject to standardisation by the ITU-T and ETSI,
which issue recommendations and specifications covering
ISDN equipment and interfaces. Standards also exist for
types of service, protocols and ISDN numbering.

Pulse Code Modulation

Pulse Code Modulation (PCM) is a method of converting
analogue signals into digital code. An analogue waveform is
sampled at regular intervals and a measurement is taken of
the sample point at various levels. The number obtained is
digital. The receiver recovers the original analogue signal by
reversing the conversion.

The sampling rate is 8kHz, and the sample value is translated
into an 8 bit code, to conform with ITU-T G.711. Therefore
each speech signal results in a continuous bit stream at a rate
of 64 kbps.

The process of converting between analogue and digital is
known as encoding. An encoding device when combined
with a decoder is called a Codec.

Methods of Voice Encoding

The number of levels used in the sampling, and the way they
are spread, affect the amount of signal noise and distortion.
There are two methods of encoding within the ITU-T G.711
recommendation: A-Law and µ-Law.

A-Law encoding

This is the type of voice encoding used in Europe. Sampling
consists of 4096 levels, divided into 7 segments.

1-12 429850

µ-Law encoding

This is the type of encoding used in the United States, Japan
and some other regions of Asia. Sampling consists of 8159
levels, divided into 8 segments.

Line Coding Techniques

To overcome the technical difficulties raised by sending
digitised information down a telephone cable originally
designed for 50V pulse dialling and 4kHz speech, line coding
is used. There are a number of different techniques: each one
involves coding digitised speech into different voltages which
can then be transmitted down the telephone lines.

2B1Q line coding

Introducing AuroraPlus

The name 2B1Q comes from the method of coding 2 binary
digits (2B) as one of 4 voltage levels (1Q, where Q stands for
‘quaternary’).

4B3T line coding

The name 4B3T comes from the method of coding 4 binary
digits (4B) as a group of 3 voltage levels (3T, where T stands
for ‘ternary’).

Basic Rate & Primary Rate ISDN

Equipment on an ISDN network may be connected either
through a Basic Rate interface or a Primary Rate interface.

• Basic Rate (BRI) consists of two B channels and one D
channel, known collectively as 2B+D.

• Primary Rate (PRI) consists of 30 B channels and one
D channel (‘30B+D’) in Europe, and 23 B channels and
one D channel (‘23B+D’) in the US.

Issue 5 - 04/01 1-13

The B channels contain user data at rates of up to 64Kbps.
The data is switched by the network in order to provide an
end-to-end transmission service.

Trend AuroraPlus User Guide

In Basic Rate the D channel carries control and signalling
data at 16kbps. It may also be used for X.25, the Packet
mode service.

Basic Rate access to the ISDN

The diagram below illustrates Basic Rate ISDN operation.

In this illustration, a 4 wire interface consisting of a transmit
and receive pair (known as the ‘S/T interface’), is connected
to the NT1. The S/T interface is terminated at the NT1 and
the distant end, on both the transmit and receive pairs.
Connection to the interface is usually made via 8-pin plugs
which conform to ISO Specification 8877. Over this

Point-to-Point and Point-to-Multipoint links

The layer 2 of a S/T interface can operate in either
Point-to-Point (PP) or Point-to-Multipoint (PMP) mode.

• On a PP link, only one TE may be connected at the end of up
to 1km of cable.

• On a PMP link, up to 8 terminals can be connected in
parallel along the bus. The length of the bus is limited to
about 200m, depending on the cable.

Basic Rate power

Power is provided across the network so that, in the event of
a local mains power failure, a basic telephone service is still

The OSI 7-Layer Model

The Open Systems Interconnection (OSI) is an agreed,
international standard governing the way systems
communicate. The standard model has seven layers, as
follows:

Layer 1 The physical layer. Transmits bits between the

terminal and the network. It defines
connectors, line coding, transmission rates and

Introducing AuroraPlus

anything else concerning the transfer of bits.

Layer 2 The data link layer. Provides link level control.

Error detection and correction are handled by
assembling the bits into frames. All Layer 2
formats derive from a standard known as High
Level Data Link Control (HDLC).

Layer 3 The network layer. Routes messages to their

destination.

Layer 4 The transport layer. The end-to-end layer

which sets up and maintains connections.

Layer 5 The session layer. Handles the co-ordination

between processes.

Layer 6 The presentation layer provides data

Issue 5 - 04/01 1-15

formatting and code conversion.

Layer 7 The application layer. This is the task to be

performed, e.g. remote login and file transfer.

Trend AuroraPlus User Guide

Layer 1 (BRI)

Layer 1, at the S/T reference point, transfers information bits
in frames between the terminals and the NT1.

Each layer 1 frame is 48 bits long and lasts for 250
microseconds—its structure depends on the direction of
transmission. It contains two 8 bit groups of channel B1,
two 8 bit groups of channel B2, 4 bits of channel D and 12
bits used for other functions.

D Channel Contention

If two TEs attempt to make a call simultaneously, a
procedure known as D Channel Contention Resolution
prevents a collision.

Activation and deactivation

TEs and NTs can be deactivated in order to reduce power
consumption, then reactivated to normal power. Both the TE
and NT can receive activation messages, but only an NT can
instruct a TE to deactivate.

‘Info’ signals

Activation and Deactivation messages are transmitted using
‘Info’ signals.

Info 0 idle state—neither the TEs or the NT are operating.

Info 1 TE to NT—requests activation.

Info 2 NT to TE—requests activation/responds to

Info 1.

Info 3 TE to NT—contains operational data.

Info 4 NT to TE—contains operational data.

Layer 2

Introducing AuroraPlus

Layer 2 provides a secure, error-free connection for Layer 3
call control information, by organising the Layer 3 octets
into error checked frames. Layer 2 procedures, based on
HDLC, are known as Link Access Procedure for a D
Channel (LAPD).

A Layer 2 frame is structured as follows:

Flags Indicate the start and end of the frame.

Address A unique value identifying the message type

and the channel to which it refers. Contains
a SAPI (Service Access Point Indentifier) to
identify the service that the frame is
intended for, a TEI (Terminal Endpoint
Indentifier) to identify the terminal, and a
Command/Response bit.

Layer 3

Control Carries information that identifies the

frame.

Information Carries the TEI management protocol or

layer 3 message.

FC Sequence Used for error detection.

Layer 3 routes messages to their destination. The diagram
below shows the structure of the Layer 3 signalling messages.

ETSI

The ITU Q921 and Q931 recommendations are the basis of
what is commonly known as the ETSI protocol. Q931
defines the call control messages and Q921 defines the
frames that carry the messages. ETSI is the standard ISDN
protocol used within Europe.

VN

VN is the national ISDN protocol for France and it is also
used in private networks utilising equipment of French
origin. VN is similar in many respects to the ETSI protocol,
the main differences being the construction of layer 3
messages and information elements, new message types and
different teleservices.

AuroraPlus is

connected to an S Interface Point-to-Point connection.

After connection onto either the S or U Interface, the display
indicates Idle. When you try to make a call the unit initialises
the connected interface. On the S Interface this is almost
instantaneous and is not visible. On the U Interface this can
take a minute or so. During this time INIT U is displayed.
When the interface is initialised, the call progresses to the
next stage of the call establishment procedure.

POTS Check Switch (Only via U Access Cable)

The POTS Check function is activated by the POTS Check
Switch, marked 'POTS CHK'. The high impedance circuitry
means that the handset can be used to listen to analogue
signals on the line. The switch has two positions:

UP POTS Check is off

DOWN POTS Check is on

When the TERM switch is in the DOWN position, if the
line is idle, when you press the TERM Switch the unit draws
analogue dial-tone.

an internal rechargeable battery in both ISDN and Analogue
modes. The two switch positions are:

BAT Power is supplied from the internal

rechargeable battery, even when the charger is
connected.

CHARGE The internal battery is charged if the charger is

connected. If the charger is not connected,
setting the slide switch to the CHARGE
position acts as an off switch.

Charging is indicated by the red charging LED,
next to the charger connection socket. The
LED flashes when the charging process is
completed.

When the remaining battery charge drops to 30 minutes, an
audible signal is sounded and a warning is displayed on the
screen. This screen is redisplayed every 30 seconds. If the
battery level drops still further, before it fails completely, the
unit switches itself off. It cannot be switched on again until
the external charger is connected.

Termination Resistor Switch (TERM)

Correct operation of the S-bus connection (Point-to-Point or
Point-to-Multipoint) can depend on the customer wiring
being correctly terminated. The wiring must be terminated
with 100 ohms at either end of the S-bus connection in both
directions, i.e. Transmit (Tx) and Receive (Rx).

Channel Setup

The ISDN Basic Rate Interface provides for two B Channels
(Bearer Channels) and one D Channel (Demand Channel).
Each multiplexed Bearer Channel can carry either voice or
data information. During setup, you should define the
default channel to make outgoing calls with as B1, B2 or BX.
The D Channel is a fixed physical link and is not definable.

The three channels are:

• B1 (Bearer Channel 1)

• B2 (Bearer Channel 2)

• BX (either Bearer Channel)

The type of services that each channel supports can also be
defined individually. For example, B1 can be set up for voice
communication, and B2 for fax. Where the channel or
service cannot be defined in advance (for example, a cleared
call on B1 with a maintained call on B2 when a subsequent
incoming call is received) then BX can be used to
automatically find the free channel.

Supplementary Service Selection

Supplementary Services are additional ISDN services to
which users can subscribe. They supplement the functions of
Bearer Services or Teleservices.

The available supplementary services are:

• Call Forwarding • Call Hold and Retrieve

• Call Deflection • Keypad

• Three Party Call • MCID

• CCBS • User-to-user signalling

• Call suspend/resume

Call Forwarding

Call Forwarding is a service which lets you send future
incoming calls to another number instead of to your number.

AuroraPlus can be used to activate and deactivate Call

Forwarding, where this facility is supported by the network.

Call Forwarding is protocol specific.

Types of Call Forwarding

• CFU (Call Forwarding Unconditional). This enables a
call to be forwarded regardless of the line status.

• CFB (Call Forwarding when Busy). This enables a call
to be forwarded when the line is in use.

• CFNR (Call Forwarding on No Reply). This only
forwards a call when the call is not answered.

Call Forwarding types may be applied individually to each
type of ISDN service or to all services. Call Forwarding is
also programmed individually for each CLI on a
Point-to-Multipoint configuration and for the whole
interface on a Point-to-Point configuration.

4-20 429850

Types of Call Forwarding

• AWS1 (Call Forwarding unconditional).

• AWS2 (Call Forwarding when there is no reply, when

the line is busy or when there is no Terminal
Equipment or the equipment is out of order).

The call screening on Call Forwarding is typically used where
the CPN has auto switched fax equipment and the Call
Forward number has not.

Types of Call Forwarding

Call Forwarding is either Unconditional or No Reply,
depending on which service has been subscribed to.

Notes on entering Keypad Codes

If the characters you enter start with # or *, and end with #,
they are sent in a keypad facility information element.

For example if you enter *21*6489#, it will be sent in a
keypad facility information element.

If you enter characters after the #, they are sent as a Called
Party Number information element.

For example if you enter *01*6489#90698, then *01*6489#
is sent in a keypad facility information element, and 90698 is
sent in the Called Party Number information element.

If the characters you enter start with a number, they will be
sent in a Called Party Number information element.
