Welcome to auroraSonata - Section 2
Introducing
auroraSonata
auroraSonata allows you to test ISDN links on a range of
different interfaces depending on which interface modules are
fitted.
auroraSonata may be fitted with S and/or U interface modules for
testing Basic Rate links and a Primary Rate (PRI) module (E1
transmission).
How you can use your auroraSonata
Depending on the type of test you perform, you can check one
or more of the following:
•
ISDN equipment and lines
•
the route through the network via ISDN switches
•
the operation of the call control protocols
•
ISDN fixed links, which do not use protocol support
•
the integrity of a call and the quality of service
•
the availability and operation of ISDN services
The basic methods for testing
There are two main ways in which you can use auroraSonata—
these are known as the operating modes. They are:
•
Simulation mode—you use the unit to simulate the
operation of Terminal Equipment (TE), a Network
Termination (NT) or a Line Termination (LT).
auroraSonata can generate or receive the network clock
and act as the protocol ‘master’ (network side), or
‘slave’ (user side).
•
Monitor mode—auroraSonata monitors user traffic and
protocol information on the line in real time.

Safety advice
When using auroraSonata, always take basic safety precautions to
reduce the risk of fire, electric shock and injury to persons.
These include the following:
•
Avoid using the tester during an electrical storm—
there is a remote risk of electric shock by lightning.
•
Use only the batteries supplied for the unit. These
are described in Chapter 8 and in the power source
specifications in Chapter 9 section 1.
•
Do not dispose of batteries in a fire—they may
explode.
•
Disconnect all interface cables before removing the
battery cover.
•
Never remove the rear of the case while auroraSonata is
switched on or connected to the network.
You must also observe all safety warnings related to the power
supply. These are set out in Chapter 8.
Looking after auroraSonata
Although light and portable, auroraSonata is very robust and has
been designed to operate in a typical outdoors working
environment. For example, it can survive a fall onto concrete
from a height of up to two metres.
To ensure reliable operation, avoid:
•
very high or low temperatures—auroraSonata is
designed to operate between -15°C and +55°C,
although you should only charge the battery between
+10°C and +30°C. You can store the unit safely
between -25°C and +70°C.
•
very wet conditions—auroraSonata is weather-resistant
but not waterproof. You can use it in light rain when
held vertically, but you should never immerse the
unit in water.

Setting the emulation mode
The way in which auroraSonata emulates ISDN equipment or the
network itself is called the emulation mode. This is a
combination of settings which you define to suit the test you
intend to perform.
The following pages describe each setting in turn, explaining
what it is for and how to set it up. Following this is a set of
examples indicating which combination (i.e. emulation mode)
you would choose for different tests. Finally, it explains how
to use auroraSonata’s Hot Keys as a quick and easy way to change
the setup of auroraSonata.

Identifying the protocol master and slave
To test ISDN protocol links, you need to identify whether
auroraSonata acts as the ‘master’ or ‘slave’ of the network at
Layer 2. To test fixed links, you can set auroraSonata to operate
without Layer 2 protocol.
Tip
Usually, when auroraSonata emulates a TE it acts as protocol
slave, and when emulating an NT or LT it acts as protocol
master. However, you can use the opposite settings (TE
Master, NT Slave, LT Slave), if required. For example, you
might use NT Slave in order to use auroraSonata as a protocol
slave and a clock master.

For example, S TE s PP m means that auroraSonata is operating
on the S interface, emulating a TE, acting as Slave at Layer 2
level, with point-to-point as the link type, acting as Master of
the Layer 3 protocol.
Selecting the type of ISDN protocol link (PP/PMP)
When testing a Basic Rate link that uses ISDN protocol
support (i.e. it is not a fixed link) you need to specify whether
you intend to test an ISDN point-to-point (PP) link or a
point-to-multipoint (PMP) link.
CorNet-N and TN1R6-N only operate on point-to-point
links. Therefore, with these protocols, only the PP (point-topoint) option is available for the Line Type setting.
CorNet-T and TN1R6-T can operate on point-to-point or
point-to-multipoint links.

Setting up auroraSonata using Hot Keys
auroraSonata has six Hot Keys, which allow you to configure the
unit quickly without having to redefine each individual setting.
You can customise the Hot Keys to suit your requirements.
Displaying the current list of Hot Keys
-1-
In the top level menu, press the Hot function
key to list the available Hot Keys. For example:
Each interface has its own set of Hot Keys. The title bar on
the screen shows which interface is currently selected—for
example, S Hot Keys.
Tip
To see details of the settings assigned to a Hot Key, highlight
its number and press ENTER.
How the Hot Keys work
Each of the most commonly used combinations of settings for
the selected interface is assigned to a Hot Key. When you want
to set up auroraSonata in a particular way, you simply select the
Key to which the settings are assigned.
When you use Hot Keys to set the emulation mode for
auroraSonata, the list of available keys is always appropriate to
the selected protocol. For example, if a protocol only operates
on point-to-point links there are no Hot Keys selecting pointto-multipoint operation.

25/07/00, 10:23
First Steps in Testing - Section 1
Each Hot Key has a different combination of settings for:
•
the device which auroraSonata emulates
•
whether auroraSonata acts as protocol master or slave
•
the type of link to be tested
•
the way in which B channel Terminal Endpoint
Identifiers (TEIs) are assigned
•
the value or values for fixed TEIs.
From the Hot Key screen you can also change to a different
protocol.
Preconfigured Hot Keys
auroraSonata comes with a series of preconfigured Hot Keys for
each interface. The name of each Key indicates the settings
assigned to it.
For Basic Rate operation, the protocol master/slave setting is
indicated as follows:
TE
Emulate a TE, acting as protocol slave
NT Emulate an NT, acting as protocol master
LT
Emulate an LT, acting as protocol master
For example, TE PP TEI 0,0 means the Hot Key configures
auroraSonata to emulate a TE, testing a point-to-point link, with
fixed B channel TEI values of 0, 0.
Note
Remember that the available emulation settings, and therefore
the available Hot Keys, are determined by the interface you
have selected. When the S interface is selected, for example,
there is no Hot Key that sets up auroraSonata to emulate an LT.
For Primary Rate operation, the name of each Hot Key shows
the emulation mode and protocol master/slave setting: for
example, NT Slave or TE No D Chan.

Laye r 2 link
Automatic
auroraSonata sets up the link only when you make a
call. The link may be released again when the call
is cleared.
Pe rmane nt When you first switch on auroraSonata, it sets up the
Layer 2 link. It keeps up this link and uses it each
time you make a call.
If auroraSonata cannot set up the link when it is
switched on, it tries again when the first call is
made. If it succeeds, it keeps up the link for future
calls.
Note
This setting also determines the point at which Layer 1
activates for a call—for details, see Activation of Layer 1 in
Chapter 4 section 2. If Layer 1 is not operating properly,
auroraSonata cannot set up the link at Layer 2 level.
Selecting the way in which B channel TEIs are
assigned
For Basic Rate operation you can determine whether TEIs are
assigned by the network (Automatic) or manually (Fixed)
and, for fixed TEIs, assign one or two TEI values.
When CorNet-T and TN1R6 are selected and you are testing a
point to multipoint line, you can set up fixed TEI settings.
CorNet-N or TN1R6-N can only operate on point to point
lines, therefore you cannot set TEIs and they are set to 0,0.

When TEIs are assigned automatically, the network
ensures that no two terminals on the link have the same
TEI. When you assign them manually, you must check
this yourself.
Setting up auroraSonata to generate call charging
You can define the way in which auroraSonata generates charging
information (known as Advice of Charge or AOC) and sends
it to the caller for incoming calls. This is only used when
auroraSonata is emulating a Network Termination (NT).
If VN4 is selected and you are emulating a TE, auroraSonata
allows you to request charging information from the NT.
When CorNet-T is selected you cannot configure auroraSonata as
a NT, therefore you cannot set up charging information.
If TN1R6-N and CorNet-N are selected charging information
can be generated by either the TE or NT.

Configuring the serial port/protocol output
auroraSonata has a two-way, high speed RS232 serial port, which
is used to connect the tester to another device such as a PC or
printer. For example, you would connect to a PC to use
auroraExpert for Windows. To configure the serial port:
-1-
From the main Setup menu, select Comms/
Tracer to display the Comms/Tracer menu.
Note
The Tracer setting in this menu is used both to determine
what is output at the serial port and to select the format and
destination of the protocol decode. For more information on
protocol analysis, see Chapter 7.
Choosing the serial port output
auroraSonata’s RS232 port can be used:
•
to print test results
•
to output results of a BERT as it is performed
•
to print a protocol information from a test call
or monitor session that has been saved to
auroraSonata’s memory.
•
to output protocol information while a test call
or monitor session is in progress.
Note
For more information about protocol analysis, see Chapter 7.

Saving the current settings as custom defaults
Suppose you have set up auroraSonata in a particular way to suit a
series of tests you are performing. However, you now need to
perform one test where the settings are different.
To avoid having to change the settings twice, you can save the
current settings, change them for the new test and then go
back to the settings you were using. To do this:
-1-
From the Set Defaults menu, select Save
Defaults. auroraSonata displays a pop-up window
prompting you to confirm that you wish to
save the current settings as custom defaults.
-2-
To confirm, press the OK function key. To
cancel, press ESC.
Note
auroraSonata stores these settings until the next time you return
to the factory defaults, even while the tester is switched off.
Returning to the custom defaults
-1-
From the Set Defaults menu, select Get
Defaults. auroraSonata displays a pop-up window
prompting you to confirm that you wish to
select the custom defaults.
-2-
To confirm, press the OK function key. To
continue without changing any settings, press
ESC.
Note
If auroraSonata does not return to your custom defaults, it is
probably because you have returned to the factory defaults
since the custom ones were set. Returning to the factory
defaults always cancels your custom defaults.

First Steps in Testing - Section 2
Connecting a
Basic Call
This section explains how to use auroraSonata to connect
outgoing and incoming calls, display call status and clear calls.
Note
To set up calls, auroraSonata must be in Simulation mode—that
is, emulating an ISDN device or the network itself. For details,
see Choosing the operating mode in Chapter 2 section 3.
The purpose of connecting calls
Often, the first test you would perform on an ISDN link you
are provisioning or maintaining is to connect auroraSonata to the
line and check whether you can make a call between it and
one of the following:
•
another piece of ISDN equipment
•
a Terminal Adaptor (TA) connected to non-ISDN
equipment
•
another ISDN tester
•
another B channel on your own auroraSonata
Once you have a connected call you can use it as the basis for
testing line quality, service availability and so on. You will find
full instructions for these tests in Chapter 4.
Tip
auroraSonata’s ISDN Test Suite allows you to check many
features of the link at the touch of a button. For an
introduction to the Test Suite, see Chapter 4 section 1.
If the call fails, you can perform further tests to find out more
about the problem. For example, you might test the physical
link or try to make calls using other ISDN services.

-3-
From the top level menu, select Simulate.
auroraSonata displays a menu listing the tasks you
can perform in Simulation mode.
Selecting a channel for testing
When you make a call, auroraSonata uses the channel which is
currently selected. You can select a specific B channel or set up
auroraSonata to use any available B channel (Bx). You cannot
connect a call on the D channel unless you have X.25 installed
on your unit (see the X.25 Operation Annex for details), but
on a Basic Rate fixed link you can perform D channel BERT—
see Chapter 4 section 2 for instructions.
When TN1R6-T or TN1R6-N are selected, the Emulation
menu has an additional setting: L3 Protocol. This setting
determines whether it is auroraSonata or the connected device
that chooses the channel to be used for a call. For details, see
Identifying the Layer 3 master and slave in Section 2 of this
chapter.
When auroraSonata is emulating a TE and TN1R6-N is selected,
channel Bx is the default bearer channel.

and press ENTER. For a list of the services that
are available for the different protocols, see
Chapter 4 section 4.
Notes on speech calls
Although you can have speech calls in progress on all B
channels simultaneously, the Codec (audio coder/decoder) can
only be connected to one B channel at a time. In other words,
you can only talk or listen to the channel that is currently
displayed on the screen.
Setting up dialling information for the call
To make the testing process more convenient, auroraSonata lets
you access the Dial Options menu (see Setting up dialling
information in section 1) from the Outgoing ISDN Call
screen as well as from the main Setup menus.
You can use the Dial Options menu to test a number of ISDN
supplementary services (see Chapter 4 section 5), use a semipermanent connection (1TR6 only) and select a numbering
plan and type for the Called Party Number and Calling Line
Identity.

Selecting the dialling mode
The dialling mode is the way in which the digits you dial for
outgoing calls are sent to the line.
If you are using Siemens HICOM ISPBX equipment with
software version 3.3 or later you must use En bloc dialling. If a
data call using overlap dialling is attempted, it is rejected by
the ISPBX, and Cause Code 100 (Invalid information element
contents) is displayed.
The call is rejected because the call is cleared by the ISPBX
using an unspecified or undocumented call clearing of 52. This
is a known problem of the ISPBX.

From the Outgoing ISDN Call menu, select
Dial Mode to display the options:
-2-
Highlight the dialling mode you require and

The digits are all assembled in one Call Control
Packet before they are sent. The entire packet is
then sent at once, in the initial call setup message.
Ove rlap Each digit is sent in its own Call Control Packet,
either individually as it is dialled or with other digits
when dialling is complete.
Note
You can only use a sub-address with En-Bloc dialling. With
Overlap dialling the connection is made as soon as you have
entered enough digits to identify the called party, so the call is
connected before a sub-address could reach the destination.

Identifying the CPN for the call
The number to which you make an outgoing call is known as
the Called Party Number (CPN).
Entering the CPN and sub-address
You enter the CPN in the same way whichever dialling mode
you use, but you can only use a sub-address in En-bloc mode.
Tips:
•
The most recently dialled CPN and sub-address (if used)
are shown on the Outgoing ISDN Call menu. To call
this number again, simply leave it as it is and proceed
with the call.
•
For details on how to identify a CPN numbering plan
and type, see section 1.
To change the CPN:
-1-
From the Outgoing ISDN Call menu, select
CPN to open an entry window.
Tip
To dial a new number instead of changing digits on the
existing one, simply move the cursor to CPN and start typing
digits. The entry window opens automatically, showing the
digit you have just entered.
-2-

Receiving an incoming call
The way in which incoming calls are connected on auroraSonata
depends on whether the call is a data or speech type call.
•
When auroraSonata receives an incoming speech call,
you always answer it manually.
•
For incoming data calls, you choose in advance
whether auroraSonata connects automatically or waits
for you to connect manually. You would choose
automatic connection when, for example, you intend
to make a self call for BERT.
Tip
You can set up auroraSonata to screen incoming calls and present
only those from or for a particular number. See Chapter 6
section 1.
Note
When no channel is free to connect the call and Call Waiting is
supported, auroraSonata displays a Call Waiting menu. See
Incoming calls when channels are busy later in this section. If
Call Waiting is not available, the call is rejected with a User
Busy Cause Code.

Looping back the call
A loop is a continuous transfer of information when
auroraSonata transmits all data that receives. When auroraSonata
receives information, it sends it back on the same channel. You
would normally loop back information on a call to synchronise
a BERT pattern, the BERT pattern that is transmitted by
auroraSonata is also received. See Chapter 4 section 2.
Note
This section relates to a standard ‘framed’ loop—i.e. one
where the data is separated into different timeslots. On a
Primary Rate link you can also set up an ‘unframed’ loop,
where the data is sent as a full 2-megabit stream. See
Unframed Layer 1 tests in Chapter 4 section 2.
There are two types of loop:
•
remote—information produced by auroraSonata is
looped back by another device.
•
local—auroraSonata loops back the information it
receives from another device. You could use a local
loop, for example, to return incoming BERT.
Note
In Unattended mode (see Chapter 6 section 2), auroraSonata
loops back all incoming voice or data calls automatically.
Setting up a loop
You can place loops on any B channel, individually or
simultaneously, and remove a loop without disturbing any
others that are set up.

channels simultaneously, the Codec (audio coder/decoder) can
only be connected to one B channel at a time. When you have
two or more connected speech calls, the Codec is connected
to the channel you are currently displaying. To listen to a call
on another B channel, you simply switch to that channel.

Origin of the Cause Codes
auroraSonata receives the Cause Code from the network. The
message type depends upon which party initiated call clearing.
•
When you clear the call, auroraSonata receives a
Clearing Cause Code in the Release message.
•
When a remote user or the network initiates call
clearing, auroraSonata receives a Disconnect Cause
Code in the Disconnect message. When you finish
clearing, it receives a Clearing Cause Code in the
Release Complete message.
If calls are not possible
If a call attempt is unsuccessful, first check the displayed
Cause Code. You will usually want to perform further tests to
find out more about the problem—for example, you can
attempt a call using a different channel or service, test other
equipment on the link or use auroraSonata to monitor the line.

Introduction
This section includes:
•
advice on simulation on Basic and Primary Rate links
•
a discussion of when you might use auroraSonata to
emulate different ISDN devices
•
brief details on the types of link you can test
•
an introduction to auroraSonata’s ISDN Test Suite
Simulation on a Basic Rate link
You can use auroraSonata for simulation on the Basic Rate S and
U interfaces.
Simulation on the S interface
On the BRI S interface you can use auroraSonata to emulate
Terminal Equipment (a TE) or a Network Termination (NT).
Using the termination resistor
The S bus must be terminated with 100Ω at each end. This is
normally done by the NT and the most distant socket on the
bus.
For simulation on the S bus, you must switch auroraSonata’s
100Ω termination resistor on or off, depending on the device
auroraSonata is emulating and the other equipment on the link.
When emulating an NT, the resistor must always be On.
Only one TE on the interface can have the S bus termination
connected at any one time. Therefore, when you need to
emulate a TE on a line where there are other TEs, check
whether one of the other TEs has a termination resistor. If so,
you must switch auroraSonata’s resistor Off. If not, you must
switch auroraSonata’s resistor On.

25/07/00, 10:51
Testing in Simulation Mode - Section 1
For instructions on connecting/disconnecting the resistor, see
Terminating the S bus in Chapter 3 section 1.
Emulating a TE on the S interface
You would use auroraSonata to emulate a TE on the S interface:
2
•
to determine whether a TE is faulty
•
to check the line reliability (e.g. using BERT)
•
during line provisioning or maintenance, to test
the line configuration, line quality and the
availability of channels and services
•
to check any subscribed supplementary services
Note
You must set up the 100Ω termination resistor as appropriate.
Emulating an NT on the S interface
When you emulate an NT at the S interface you are using
auroraSonata to replace the NT and the ISDN. You can use this:
•
when installing a TE—you can make test calls
to auroraSonata instead of the ISDN
•
during line installation, to check the operation
of S bus connections
•
when troubleshooting a TE—to check if there
is an fault with the ISDN at the S interface.
When emulating an NT, auroraSonata sends ringing tones to the
TE in the same way as an exchange would do.
2
Notes:
•
You must use an 100Ω termination resistor when
emulating an NT on the S interface.
•
NT powering can be supplied by an optional ‘Phantom
Power Feed Box’ (PPFB) capable of supplying power to
one TE on an S-bus or U interface. For more information
on the PPFB, contact your Agilent Technologies
representative.

auroraSonata Hand Held ISDN Tester—User Guide
Simulation on the U interface
On the U interface, you can use auroraSonata to emulate
Terminal Equipment (a TE) or a Line Termination (LT) device.
Emulating a TE on the U interface
When auroraSonata emulates a TE on the U interface, it operates
as both the NT1 and the TE. You would use this:
•
to check the interface during line installation
•
to find out whether a suspected fault is on the
U interface side of the NT
auroraSonata can emulate a TE on the U interface using 2B1Q,
4B3T or Up0 line coding, when the appropriate module is
fitted.
Emulating an LT on the U interface
You would use auroraSonata to emulate an LT:
•
to test towards the NT (check the local loop)
•
to test the line from the exchange end
auroraSonata can emulate an LT on the U interface using 2B1Q,
4B3T or Up0 line coding, when the appropriate modules are
fitted.
‘NT replacement’ test
When your auroraSonata is fitted with one S and one U interface
module, you can disconnect the NT and replace it with
auroraSonata. This allows you to test whether the NT is faulty.

Testing in Simulation Mode - Section 1
Simulation on a Primary Rate link
On a Primary Rate link you can use auroraSonata to emulate
Terminal Equipment (a TE) or a Network Termination (NT).
Terminating the link
When using auroraSonata for simulation on a Primary Rate link
you must set its resistor to 75Ω or 120Ω to suit the equipment
to which you are connecting. For instructions, see Terminating
a Primary Rate link in Chapter 3 section 1.
Emulating a TE on a PRI link
You would use auroraSonata to emulate a TE on a PRI link:
•
to determine whether a TE is faulty
•
to check the line reliability (e.g. using BERT)
•
during line provisioning or maintenance, to test
the line configuration, line quality and the
availability of channels and ISDN services
•
to check any subscribed supplementary services
Emulating an NT on a PRI link
When you emulate an NT at the S interface you are using
auroraSonata to replace the NT and the ISDN. You can use this:
•
when installing a TE—you can make test calls
to auroraSonata instead of the ISDN
•
during line installation
•
when troubleshooting a TE—to check if there
is an fault with the ISDN.
When emulating an NT, auroraSonata sends ringing tones to the
TE in the same way as an exchange would do.

Using an external source for the network
clock
Normally, when auroraSonata emulates an NT, it generates the
network clock. However, on a Basic or Primary Rate link you
can take the network clock from an external source.
-1-
Connect a network link into the top connector
for the S or PRI interface module, using the
4-4 cable.
Tip
This is useful, for example, when testing into a PBX which has
more than one network connection. If you have any queries
about this mode of operation, contact the Agilent
Technologies Help Desk.
Testing ISDN links
There are two main types of ISDN link:
•
links which use ISDN protocol transactions for call
control. For Basic Rate such links may be either
point-to-point or point-to-multipoint, while for
Primary Rate they are always point-to-point (see the
Introduction to ISDN for details).
•
‘fixed’ links, which do not use protocol support
For guidelines on how to set up auroraSonata to test each type of
link, see Setting the emulation mode in Chapter 3 section 1.
Notes on testing fixed links
A fixed link is a point-to-point link consisting of a single,
dedicated ISDN circuit between a TE and an NT. No ISDN
protocol support is used for call control, so there is no call
setup process.
To test a fixed link, you must set L2 protocol (see Setting the
emulation mode in Chapter 3 section 1) to No D Chan.
During a fixed link call auroraSonata displays No D Chan.
4-8
Chap04s1.P65
427869
8
25/07/00, 10:52
Testing in Simulation Mode - Section 1
You can test fixed links with BRI or PRI access, provided the
appropriate interface module is fitted. For Basic Rate you can
test fixed links at the S interface or at the U interface using
2B1Q, 4B3T or Up0 line coding. There are two methods:
2
•
replacing the NT with an auroraSonata
•
connecting auroraSonata and another device (e.g. a
Agilent Technologies ISDN tester) at either end
of the link, with one emulating a TE and the
other an NT
Notes:
•
Because there is no D channel protocol, there is no way
to tell when auroraSonata receives a fixed link call. Both
ends of the link must be set up for fixed link operation.
•
When auroraSonata is set up to test fixed links you do not
have the option to use ‘any’ B channel (Bx) for the test.
For details on channel selection, see Chapter 3 section 2.

auroraSonata’s ISDN Test Suite offers you a quick and easy way
of performing the most common tests on an ISDN link.

How the Test Suite works
The Test Suite has five ‘one-button’ tests, each consisting of a
different set of ‘component’ tests which can be enabled or
disabled for a test run. Four of the tests are preconfigured to
allow you to select from a specific set of components. You can
configure the fifth test to suit your own requirements.
The preconfigured one-button tests
Four of the one-button tests are preconfigured with one or
more of the component tests most commonly used in line
provisioning. For example, the Available services test
contains components to test ISDN teleservices and a range of
supplementary services.
You can enable or disable each component before running the
test. For example, for Available services you can choose to
test only ISDN teleservices, or specific supplementary services.
Tip
To perform all the checks normally required during line
provisioning, run the four preconfigured one-button tests in
sequence with all components selected.

The component tests
Each one-button test offers one or more of the following
component tests for selection:
•
X.25 TEI availability
•
an Outgoing Channel test
•
a Full Channel test
•
a Bit Error Rate Test (BERT)
•
availability of each of the ISDN teleservices
•
availability and operation of the Calling Line ID
Presentation/Restriction (CLIP-R), Connected Line
ID Presentation/Restriction (COLP/R), Subaddressing and Advice of Charge (AOC)
supplementary services
For TN1R6-N and TN1R6-T, the Outgoing Channel Test
component is only available when L3 Protocol in the
Emulation menu is set to Master. See Identifying the Layer 3
master/slave in Section 1 of Chapter 3.
When L3 Protocol in the Emulation menu is set to Slave
auroraSonata can only identify that a teleservice is available on a
link, it cannot identify which channel the teleservice is
available on.

one-button tests, see the appropriate sections of this chapter.
2
Note
When you change the CPN for any individual component,
auroraSonata automatically uses it for all components in all onebutton tests to save you time. You can use a self-call— e.g. for
BERT, if you want to use auroraSonata to perform the loopback.
During the test
While a one-button test is in progress, auroraSonata displays the
results of each component on screen as they occur. You can
stop the test at any time by pressing the Abort function key.
Viewing and printing stored results
auroraSonata stores the most recent set of results for each
component test, and up to 30 sets for the BERT component.
2
Note
The results of a component test are also displayed on screen
during and after the test.
auroraSonata lets you view the most recent results of all types of
test, even if a test was performed while a different protocol
was selected and is not available with the current protocol.
In other words, when CorNet-T is selected, X.25 TEI (for
example) is still available in the Review Results menu and
you can still use it to see the results of the most recent X.25
TEI test.

Physical & Line
Quality Checks
This section explains the ways in which you can use auroraSonata
to check the physical communications interface and the
quality and configuration of the ISDN line. It covers checks
for:
•
line voltage
•
the status of OSI Layers 1, 2 and 3
•
detection of Near/Far End Block Errors
(NEBE/FEBE) at the U interface (2B1Q only)
•
TEI availability for X.25 operation
•
line quality testing (BERT)
Checking the line voltage
For all Basic Rate interfaces, you can check the voltage of the
line to which you are connected. auroraSonata can display the
voltage to an accuracy of 1V, between +250V and -250V.
-1-
Press
+ 6 to display the ISDN call
information screen. For full details of this
display, see Getting information about the
current or last call in Chapter 3 section 2.
-2-
Scroll down to display the PS1 and PS2 values.
Understanding the voltage display
For the S and Up0 interfaces, the display indicates whether the
voltage is correct (OK), too low (under) or too high (over)
for the interface. For example, on the S interface it might
show 41v OK or 33v under.

auroraSonata Hand Held ISDN Tester—User Guide
Warning: High voltages
If the word ‘over’ appears after the voltage measurement for a
U interface, refer to Chapter 9 section 1 for the maximum
voltage that can be applied safely. A reading above this level
means that a dangerous voltage may be present. Disconnect
auroraSonata from the line, observing all safety precautions.
Checking Layer 1
Layer 1 (the ‘physical’ layer of the OSI 7-layer model) is
responsible for the electrical, mechanical and interface aspects
of transmitted data. For calls to be possible, Layer 1 needs to
be active—i.e. available for passing Layer 2 frames.
Tip
You will find more information about the OSI 7-layer model
in the Glossary and the Introduction to ISDN.
In Simulation mode, you can tell whether Layer 1 is active by
checking the Line A LED. Off means that Layer 1 is not
active, flashing green means that Layer 1 is activating and
steady green means that Layer 1 is fully active.
Activation of Layer 1
The point at which Layer 1 activates is determined by when
auroraSonata establishes the Layer 2 link—i.e. the Mode setting
in the Layer 2 menu. When this is Permanent, Layer 1
activates as soon as you connect to the line. When it is
Automatic, Layer 1 activates when you make or receive a call.
For details of Layer 2 setup, see Setting up the Layer 2
protocol in Chapter 3 section 1.
Layer 1 activation may take up to 35 seconds when connecting
to a CorNet-T switch. This is a feature of the ISPBX which
may vary according to the load.

The result of attempting a data call from an auroraSonata which
has been identified as a speech device (SET751 or SET
SET500) is indeterminate.
The result of attempting a speech call from an auroraSonata
which has been identified as a data device (DCI521 or
DCI731) is indeterminate.
Unframed Layer 1 tests
On a Primary Rate link, you can test Layer 1 by setting up an
unframed loop or unframed Bit Error Rate test (BERT).
‘Unframed’ means that instead of being divided into timeslots
(‘framed’), the data is transmitted as a full 2-megabit stream.
You can therefore test line quality over the entire link rather
than over a specific channel.
Tip
For details of how to set up a standard (i.e. framed) loop on a
call, see Chapter 3 section 2. A full description of BERT and
instructions on performing a framed test are provided later in
this section.
Before you set up an unframed BERT or loop, check that the
device to which you are connecting auroraSonata is configured to
transmit and receive unframed information (i.e. it has an
unframed loop).
-1-
From the main Simulate menu, choose Layer 1
Test.
-2-
Highlight either Unframed BERT or
Unframed Loop and press the Go function
key.

Performing an unframed BERT
When you select Unframed BERT, auroraSonata displays the
standard BERT screen for the test, setting up and running the
test is performed in the same way as the standard BERT.
For full instructions, see the main Bit Error Rate Testing
(BERT) information later in this section.
Setting up an unframed loop
When you select Unframed Loop, auroraSonata provides a loop
so that all data it receives from the remote device is sent back
out as a full two-megabit transmission. You would use this
when performing an unframed BERT.
While the loop is set up, the following screen is displayed:
To stop the unframed loop:
-1-
Press ENTER to select STOP.
Sending a test tone on a 2B1Q link
The 40kHz test is used to send a 40kHz tone at -12 dBm
(decibels) across the line from the remote end, to be used by a
tester at the exchange (a TIMS tester) to measure signal loss.
This test may only be used on the Basic Rate U interface with
2B1Q line coding.

(see Chapter 3 section 1), the CRC LED lights up red when a
CRC4 error is detected. The LED remains red for as long as
the error is present.
Note
For normal operation, CRC4 checking is enabled.
Returning RAI signals
When Return RAI is enabled in the ISDN Setup menu (see
Chapter 3 section 1), auroraSonata returns Remote Alarm
Indicators (RAIs) to the remote end when it is not receiving a
proper signal.

Testing in Simulation Mode - Section 2
Checking the status of Layers 2 and 3
Layer 2 of the OSI 7-layer model is the Data Link layer. It
performs the Link Access Procedure on the D channel
(LAPD).
The Layer 3 (Network Layer) protocol provides the means to
establish, maintain and terminate network connections (ISDN
calls).
Tip
You will find more information about the OSI 7-layer model
in the Glossary and the Introduction to ISDN.
In Simulation mode, the status of Layers 2 and 3 is indicated
by vertical arrows on the Status bar. For example:
Notes
•
Layer 1 must be active before Layers 2 and 3 can
operate.
•
If Layer 2 is not active, then Layer 3 cannot operate,
since Layer 2 passes Layer 3 information along the line.
If Layers 2 and 3 are not active
If Layers 2 and 3 are not active, check that auroraSonata is set up
correctly for the link—the protocol is correct, the tester is
configured to test the appropriate type of link, B TEI
allocation is set up as required and so on.

Checking the protocol activity
When auroraSonata detects protocol information being passed
along the line, the Line A LED shows yellow for as long as the
information is present.
During a call, auroraSonata displays a simple decode of the
to activate the
protocol information. To view this, press
Decode window in the Connected menu. For example:
For more detailed analysis, you can send the protocol
information to auroraSonata’s serial port or save it to memory. See
Chapter 7 section 1 for instructions.
Notes
•
There can be no protocol activity unless Layer 1 is active
(i.e. the Line A LED must be green).
•
Layers 2 and 3 must be active before the protocol
information can be passed along the line.
Detecting NEBE/FEBE (2B1Q)
auroraSonata can detect internal errors on the U interface when
2B1Q line coding is being used. Far End Block Errors (FEBE)
are errors in the transmit direction, and Near End Block Errors
(NEBE) are errors in the receive direction.
The CRC LED indicates NEBE/FEBE by lighting up red for as
long as the error is present on the line.

Testing in Simulation Mode - Section 2
Bit Error Rate Testing (BERT)
auroraSonata can perform a Bit Error Rate Test (BERT) to check
the integrity and quality of the physical communications
channel (Layer 1 or the physical wire).
Note
The instructions below relate to a standard BERT, where the
transmitted data is separated into timeslots. You can also
perform an unframed BERT—see Unframed Layer 1 tests
earlier in this section.
You can use BERT across the B channels to check an
established ISDN link on any interface. On a BRI fixed link
you can also perform D channel BERT.
Tip
You can perform BERT over voice or data type calls. However,
to test audio quality it may be simpler to make a speech call to
another engineer or a recorded service and listen to received
voice signals in the earpiece.
How BERT works
auroraSonata generates a test pattern and transmits it repeatedly
to another device, which transmits it back. auroraSonata then
compares the received pattern with the original one and
determines the rate of bit errors. The test passes or fails
depending on whether errors occur at the rate you have set to
be the ‘fail’ threshold for the line.
Tip
Although you can only perform one BERT at a time, you can
test on two channels at once by running a self call.

auroraSonata Hand Held ISDN Tester—User Guide
Remote and local testing
The receiving device may be another device sending a similar
pattern (remote BERT) or looping the call, or your own
auroraSonata (local BERT) using a self call. On a self call,
auroraSonata transmits back the received pattern by looping it
back to another B channel.
Setting up BERT operation
-1- From the ISDN Setup window, select BERT to
display a menu of BERT settings.
Tip
You can change the BERT settings during the call, to test with
different settings on the same connection. See Changing the
BERT settings while connected later in this section.

Select Duration from the BERT Setup menu to
display the options:
-2-
Select one of the following and press ENTER:
•
the test length you require
•
Continuous—the test runs until you stop
it. Continous BERT does not need a fail
rate, so the Threshold setting is removed.
•

auroraSonata displays a User Def setting.
To set a custom (User Defined) test length:
-1-
Select User Def.
-2-
Type the length in hours, minutes and seconds
(two digits for each), and press ENTER.
Setting the fail threshold
For a timed test (i.e. when Duration is not Continuous), you
need to determine the number of errors that cause the test to
fail if they occur within the designated time.
The threshold you choose depends on the specification of the
link you are testing. For example, if it requires a performance
which is almost error-free, you would set a low threshold.

The BER display shows the error rate that applies if the
currently selected number of errors occur within the selected
test time. The rate is shown as x.yE-z, where E-z means 10 to
the power of z. In the above example, the rate is 2.6x107.
You can set the threshold either in terms of a number of errors
or as an HRX percentage. HRX (Hypothetical Reference
Connection) is a model used to study the performance of
ISDN, where the percentages represent the allocation of
degraded minutes and errored seconds. For details, refer to
ITU-T Recommendation G.821.

You can choose whether auroraSonata connects incoming data
calls automatically, or whether you connect them manually.
Tip
When you intend to make data type self calls (i.e. to perform
BERT using a single auroraSonata), it is best to choose automatic
data connection. This avoids you having to answer the
incoming BERT calls and loop them back manually.

Answer is set to Manual.
Sending BERT results to the serial port
You can set up auroraSonata in advance to send BERT results to
the serial port—e.g. if you want to print out the error record
during the test. To do this, you need to set the Tracer setting
in the Comms/Tracer setup menu to BERT. See Configuring
the serial port/protocol output in Chapter 3 section 1.
Performing BERT using a connected call
You can use BERT for quality checking across the B channels
on both Data and Speech type calls.
Tip
This section explains how to perform a one-off BERT over an
established connection. However, when you are testing line
quality as part of a series of checks—for example, during line
provisioning—you can use auroraSonata’s ISDN Test Suite. See
Performing BERT from the Test Suite later in this section.

auroraSonata displays the length of time the test has been running
(Time:) and counts bit errors as they are detected. You can
scroll through this display.
For details of the error display, see Understanding the bit error
display later in this section.
At any time you can stop the test manually, insert an error or
reset the counters to zero.
Checking that the patterns are synchronised
For BERT to be reliable, the pattern auroraSonata receives back
across the line must be synchronised with the pattern it is
transmitting, so that they can be compared.
To check that this is the case, look at the BERT Sync LED.
Steady green means that the patterns are synchronised. If
they are out of step, check that the remote end is looping back
and sending the same pattern as your auroraSonata.
Notes
•
BERT statistics are not recorded until synchronisation is
achieved.
•
You can loop back information on the D channel to
synchronise BERT patterns, but only on a Basic Rate
fixed link.
Checking that the test is working properly
At the start of the test, you can inject a single bit error into
the data stream and check that it is detected. To do this:
-1-
Press the Error function key.
-2-
Check that the error has been detected.
-3-
Press the Reset function key to reset the
counters to zero and begin the ‘real’ test.

Channel Testing
This section explains how to test the availability and
configuration of the B channels for ISDN calls.
Although you can check that a channel is available for calls
against a single ISDN bearer service by connecting a call using
the appropriate service, the simplest way to perform a
complete channel check is to use auroraSonata’s ISDN Test Suite.
Tip
For an introduction to the ISDN Test Suite and its
applications, see Introducing the ISDN Test Suite in section 1.
The Test Suite allows you to test channel availability and/or
configuration against a range of ISDN bearer services. You
might perform these checks as part of a series of tests—for
example, during line provisioning.
Checking channels from the Test Suite
When CorNet-T is selected the Test Suite is not available.
There are two available components for the Channel test:
•
Outgoing Channel test—establishes and clears
an outgoing call on each B channel in turn. This
tests channel availability.
•
Full Channel test—establishes a call on each B
channel until all channels have an active call,
then clears the calls in the order in which they
were established. This tests the configuration
of the B channels.

established successfully and cleared normally. It fails when
calls are not established successfully, or are cleared with
abnormal causes.

Availability
This section explains how to test the availability of
telecommunications services for ISDN calls, and TEI
availability for X.25 operation.
Bearer services and teleservices
A bearer service (e.g. Data 64K) provides the basic capability
for transmission of signals between user-network interfaces. A
teleservice (e.g. Telex) provides the complete capability for
communication between users by means of terminals, network
functions etc., according to established protocols.

Testing services from the ISDN Test Suite
You can check that an individual bearer service or teleservice is
available by connecting a call using that service. However,
when you need to check the availability of more than one
ISDN teleservice (for example, during line provisioning), the
quickest and easiest method is to use auroraSonata’s ISDN Test
Suite.
When CorNet-T is selected the Test Suite is not available.
When L3 Protocol in the Emulation menu is set to Slave
auroraSonata can only identify that a teleservice is available on a
link, it cannot identify which channel the teleservice is
available on.
Tip
For an introduction to the ISDN Test Suite and its
applications, see Introducing the ISDN Test Suite in section 1.
How the test works
Before running the test, you select a range of services to be
checked. auroraSonata sets up a series of calls to an exchange or
remote device which you have selected, using each service in
turn. Each call is either accepted or rejected. If a service is not
available, auroraSonata marks the service as having ‘failed’ and
moves on to the next service.
Note
auroraSonata also marks the service as a Fail and moves on to the
next one if the test call fails with an internal cause—i.e. a
Cause Code above 127.

Pass means that the test call for the service was successfully
established and cleared normally. Fail means that the call could
not be established, or was cleared with an abnormal cause.
The Status bar shows the service currently being checked. In
the above example, auroraSonata is checking Video.
When the test is complete, auroraSonata lists the results for all
services that have been tested. It also stores the most recent set
of results for the Teleservice component—you can view this
from the Review Results menu (see section 1).

Checking TEI availability for X.25
As well as TEIs for ISDN operation, the network assigns TEIs
for the use of D channel X.25. There are 63 possible values.
You can use auroraSonata’s ISDN Test Suite to check which TEIs
are assigned in the network for D channel X.25.
How the test works
Before running the test, you set up a range of TEIs to be
tested. When you start the test auroraSonata transmits a series of
Layer 2 SABMEs, one at a time, each containing SAPI 16 and
one of the TEIs in the range you have set up.
If auroraSonata receives a response from the network, it means
that the network has recognised the TEI, and auroraSonata
indicates a ‘pass’. If the network does not respond within one
second, the TEI has not been accepted and auroraSonata indicates
a ‘fail’. When each TEI has been checked, auroraSonata proceeds
to the next one in the range.

Note
When the test call is to be routed through two non-compliant
networks you can set Present’ to Interworking—see Setting
up CLIP/CLIR earlier in this section for details.
Connected Line Presentation/Restriction
Connected Line Restriction (COLR) allows a subscriber
receiving a call to prevent their ISDN number being presented
to a connected caller unless they specifically request it.
Connected Line Presentation (COLP) allows a subscriber
making a call to display the number of the line to which they
are connected.
Setting up COLP/COLR
To test COLP/COLR, you need to define a number and set up
auroraSonata to send it to the calling unit for all incoming calls.
You can then make calls to test whether the presentation of
this number is allowed or restricted.

remember that the displayed COL may not correspond with
the CLI of the remote device you called—for example, where
Call Forwarding has been set up.
To test COLR, you can set up a CLI (ETSI users need to set
Present’ to Restricted), and make a call to a unit which has
COLP enabled. When restriction is successful, the number is
displayed in the ISDN call information screen (
+ 6),
but is followed by an R.
Note
When the test call is to be routed through two non-compliant
networks you can set Present’ to Interworking—see Setting
up CLIP/CLIR earlier in this section for details.

Closed User Groups (CUGs)
Closed User Groups (CUGs) are groups to and from which
access is restricted.
Members of a CUG can usually communicate with each other,
but not always—it depends upon the way the network
provider has set up the CUG. Depending on the protocol and
the way the CUG is set up, the members may also be able to
make calls to users outside their group, but they cannot
normally receive calls from the outside.
To check the operation of CUGs on a link, you can assign a
CUG number to your auroraSonata, then try to make calls to
devices within and outside the CUG.
To begin setting up CUG operation on auroraSonata:

Monitoring the Line
This chapter explains how you can use auroraSonata to monitor
protocol information or listen to audio traffic on the line in
real time. This feature is particularly useful for on-the-spot
line troubleshooting.
Note
In Monitor mode you only use auroraSonata to receive
information, not to transmit.
When the appropriate interface modules are fitted, auroraSonata
can monitor on the following types of link:
•
Primary Rate
•
Basic Rate links at the S interface
•
Basic Rate links at the U interface with 4B3T or Up0
line coding. For U interface monitoring auroraSonata
must be fitted with two U interface modules of the
same type (for example, two 4B3T interfaces)
Connecting auroraSonata
The following diagrams show how you can connect auroraSonata
in Monitor mode, provided the appropriate interface is fitted:

Note on monitor connections
To connect auroraSonata to the S interface for monitoring, you
need the optional ‘T’ piece which is available from Agilent
Technologies. This allows the NT, the TE and auroraSonata to be
connected to the line at the same time.
To connect to the U interface for monitoring ,the line must be
broken.
For monitoring on a Primary Rate link you may need a ‘T’
piece, depending on the cable and switch you are using.
Setting up auroraSonata for monitoring
Before you begin monitoring, you need to determine:
•
whether you want auroraSonata to begin
monitoring automatically at a set time, or
whether you will begin the session manually
•
whether you wish to save the protocol
information in auroraSonata’s memory or send it
to the serial port
•
the Idle Code that is used to determine an idle
state (absence of activity) on a channel
•
the configuration of the serial port, if it is to be
used for output of the protocol decode.

Call screening
Sometimes you may want to accept only calls that are for a
certain number (CPN), or from a certain number (CLI). To do
this, you can set up auroraSonata to screen incoming calls.
You can screen for up to three CPNs (this is called Multiple
Subscriber Number (MSN) screening), or for a single CLI.
You can screen for one CPN and one CLI. On a point-tomultipoint link, you can also screen for up to two 1TR6 subaddresses. This is a single digit at the end of the subscriber
number to identify the terminal—it is also known as the EAZ.
Using call screening—Examples
The following examples illustrate occasions when you might
use the two main types of screening.
Example 1—Screening for Called Party Numbers
When testing a Basic Rate point-to-multipoint link, you are
likely to receive calls on more than one number.
To avoid all the different numbers causing auroraSonata to ring,
you can choose to accept only the calls that are for your own
extension. To do this, you screen by CPN—the number the
callers have dialled.
When testing a point-to-multipoint link using the 1TR6
protocol, you can use EAZ type screening instead.
Example 2—Screening for Calling Line Identity
At other times—for example, when working on a live
switch—you are likely to receive calls from several numbers.
6-6
Chap06s1.P65
427869

25/07/00, 11:24
Advanced Features & System Maintenance - Section 1
To avoid receiving repeated calls due to other traffic, you may
want to receive calls only from a specific number—for
example, another engineer connected to the link. To do this,
you screen by CLI—the number the calls are coming from.
How to set up call screening
To begin setting up screening:
-1-
From the top level menu, choose Setup.
-2-
Select Screening. auroraSonata displays a window
from which you select the type of screening
you require and identify the numbers that you
want to be accepted.
Selecting the type of screening

Identifying the numbers for screening
When you have chosen the screening type, you need to identify
the numbers to be accepted for that type of screening.
You can set up to three CPNs for MSN screening, and one CLI
for CLI screening. Each number may include a
sub-address.
You can identify one CPN for CPN screening, one CLI for CLI
screening and, on a Basic Rate point-to-multipoint link, up to
two 1TR6 sub-addresses (EAZs) for SUB screening.

Once you have identified the numbers for a screening type,
auroraSonata stores them even when you are not using that type.
When you use it again you can either screen for the same
numbers or replace them with new ones.
In the instructions below, the example screens illustrate how
to identify a CLI using the ETSI protocol.
-1-
-2-
Select one of the following, depending on the
screening type and protocol you are using:
•
CLI for CLI screening
•
CPN1, 2 or 3 for MSN screening
(CorNet-N, CorNet-T and ETSI)
•
CPN for CPN screening
(TN1R6-N, TN1R6-T and 1TR6)
•
EAZ 1 or 2 for sub-address (EAZ)
screening on a Basic Rate PMP link
(TN1R6-N, TN1R6-T and 1TR6).
Enter a CPN or CLI of up to 20 characters, or
a single digit between 0 and 8 for 1TR6 EAZ
screening. Press ENTER.
Tip
The + and ? function keys allow you to use wildcards to make
the screening more flexible. See Using wildcards for call
screening later in this section.

-3- To include a sub-address for the CLI or CPN:
•
Select SUB to display an entry window.
•
Enter a sub-address (up to 19 characters),
and press ENTER.
Using wildcards for call screening
You can make screening more flexible by using the ‘wildcard’
function keys (+ and ?) in the screening number setup
windows. You can insert a plus sign (+) at the start or end of
the number to denote ‘any digit, any series of digits or no
digits’. A question mark (?) anywhere in the number denotes
‘any single digit’. For example:
123
The number must be an exact match—only 123 is
accepted.
123+ Accept any number beginning with 123—e.g. 123,
1234 and 12345.
123? Accept only four-digit numbers beginning with
123. In this example 1234 is accepted, but not
123 or 12345.
For example, if a customer has several CPNs, all identical apart
from the last digit (016285249772, 016285249773, etc.), you
can screen for all of them by using 01628524977?.

Using self calls
As well as calling other equipment, you can set up auroraSonata
to make a call to another B channel on the same access to
which you are connected. You might do this to test
supplementary services (see Chapter 4 section 5), or to
perform local BERT (Chapter 4 section 2).
For example, in a Data type self call the receiving channel
answers the call and loops received data back to the origin.

Setting up a self call
You set up self calls in the same way as normal outgoing calls,
but remember the following specific information:
•
If you are using a Speech call, remember that the
Codec (audio coder/decoder) is only connected to
the currently displayed B channel.
•
Although you are calling the line to which your
auroraSonata is connected, you are calling a different B
channel, which may have a different CPN.
Tip
If you do not know the CPN of the other B channel, try
making a call from it to another channel. The network may
send a CLI to the receiving channel.

Testing in
Unattended Mode
You can set up auroraSonata to connect and loop back incoming
data or speech calls on any B channel when left unattended.
This is useful, for example, when investigating a fault which
only occurs occasionally. Instead of watching continuously,
you can leave the tester on site and check periodically to see
whether the error has occurred.
You can leave auroraSonata unattended and set up a link from
another device (e.g. another auroraSonata) to perform BERT or
check audio quality. For an incoming speech call auroraSonata
sends DTMF tones down the line before applying the loop.
Notes:
•
To allow auroraSonata to run in unattended mode its
automatic power-off feature is disabled, even if you have
enabled it for normal operation. Make sure the tester has
adequate power before leaving it unattended.
•
An unattended auroraSonata always connects incoming data
and speech calls automatically, even if it is set up for
manual connection during normal operation.
If Layer 2 is set to Automatic, auroraSonata cannot accept
incoming calls until after the first outgoing call has been
established. If auroraSonata is in unattended mode and Layer 2
is set to Automatic, no calls will be received.

Capturing & Analysing
Protocol Information
This chapter explains how you can use auroraSonata to capture
and decode ISDN protocol information being transmitted
across the line. It is divided into the following sections:
Section 1 Decoding in Real Time
Section 2 Capturing to Memory
Section 3 Analysing the Decode Display
About the protocol decode
Protocol information is transmitted in raw hexadecimal
format. auroraSonata can decode this information to identify the
different messages it contains.
You can then go through the decode and check whether
specific information has been transmitted, search for problems
and so on.

Capturing & Analysing Protocol Information - Section 1
Decoding in Real
Time
There are two ways to display a decode of protocol events in
real time (i.e. as they occur):
•
by viewing the simple decode which auroraSonata
displays during test calls and line monitoring sessions.
•
by sending the protocol information via the serial
port to a PC or printer, where auroraSonata can
produce a more detailed decode.
Viewing the simple real-time decode
During calls in Simulation mode, auroraSonata displays a simple
protocol decode in a background window.
To display all of the Decode window for the call:
-1-
Press the
key.
During a line monitoring session, auroraSonata displays the
simple, real-time decode in the foreground.

Freezing the decode display
You can press the Freeze function key to pause the display at
a particular section of decode, then return to the real-time
display when you have finished examining that part of the
information.
For example, you might do this when you are waiting for a
specific event to occur. When you think you see the
information on the real-time decode you can pause the display
and make sure it really is the relevant information, without
having to stop recording and risk missing the event.
-1-
Press the Freeze function key.
You can use the arrow keys to scroll up and down through the
information as required.
-2-
When you have finished examining the
information, press the RTime function key to
return to the real-time decode.
Note
You can view the decode in more detail using the extended
decode display, for information see section 3 of this chapter.

Capturing & Analysing Protocol Information - Section 1
Viewing the real time buffer contents
auroraSonata holds the most recent 8 kilobytes of the real-time
decode in a part of its memory called the ‘real time buffer’. It
continues to do this even while the display is frozen.
You can view the contents of the real time buffer to see recent
protocol events. This is a useful ‘fallback’ if, for example, a
network problem arises when you have not set auroraSonata to
save the information to memory or send it to the serial port.
Note
When you are capturing information for a test call in Simulate
mode, you can save the contents of the real time buffer in
auroraSonata’s memory for future reference. For instructions, see
Saving the contents of the real time buffer in section 2.
Tip
To capture information for a test call, start a session from the
Capture/Review menu (see section 2). You can save up to
200 kilobytes of information.
-1-
Display the review menu for a captured
Simulate session (see section 2).
-2-
Highlight Real Time and press ENTER to
display the current real time buffer contents.
For example:
Note
If you view the real time buffer when there is no call in
progress, auroraSonata shows the last information for the most
recent call. If you view during a call auroraSonata continues
adding data until the buffer is full, then freezes it until you
stop viewing.

Navigating through the information
-1-
Scroll through the decode using the arrow keys.
At the top right of the screen, auroraSonata shows
the time at which the currently highlighted
event occurred.
-2-
When you have finished viewing the real time
buffer contents, press ESC to return to the list
of sessions available for viewing.
Sending the decode to the serial port
As well as viewing a simple protocol decode displayed onscreen, you can send a more detailed decode to auroraSonata’s
serial port for output to a printer or PC.
Note
You can also output protocol information which has been
previously stored in auroraSonata’s memory. For details, see
Sending the capture session to a printer or PC in section 2.
Choosing the format for the decode
There are various formats available for decode output to the
serial port, allowing data to be analysed in different ways:
Protocol Output at the Se rial Port
De code
Expe rt
De bug
7-6
Chap07s1.P65
A partial decode of Layer 1, Layer 2 and Layer 3
signalling with full hexadecimal dump of the D
channel messages with Transmit/ Receive indicator,
time stamp and frame reference.
A full output of the ISDN protocol and auroraSonata
operation, in a format which can be analysed using
Trend auroraExpert for Windows.
An OSI protocol decode, showing the messages that
are sent between each layer in the protocol stack,
plus D Channel messages being transmitted and
received by Layer 2.
You choose a format using the Tracer setting in the Comms/
Tracer menu (see Configuring the serial port/protocol output
in Chapter 3 section 1). When you connect to a PC or printer
and begin a call or monitor session, auroraSonata begins sending
427869
decode in the selected format.

Capturing & Analysing Protocol Information - Section 2
Capturing To
Memory
You can save the protocol information for an entire test call or
monitor session in auroraSonata’s memory. This is useful on sites
where no PC or printer is available.
•
You can retrieve the stored session and display a
simple decode on screen. This allows you to view
protocol information for an entire session instead of
being restricted to the real-time buffer decode on site.
•
You can also send a stored session to the serial port,
when the equipment you require is available. For
example, you can wait until you have access to a PC
and then send the saved protocol information to a file
for analysis using auroraExpert for Windows.
Capturing the decode for a test call
You can set auroraSonata to begin capturing protocol information
to memory before you connect a test call. auroraSonata also
allows you to stop and start capturing at any time—this means
that you can capture an entire call, or only part of a call, or
information for several calls within the same capture session.
To display the options for the protocol capture:
-1-
From the main Simulate menu, select
Capture/Review.

While capturing is in progress
As auroraSonata captures protocol information for the call, it is
added to the end of any information already in the memory.
When the memory is full, auroraSonata either displays a Memory
Full message and stops saving until you delete a session, or
displays a Wrap message and begins overwriting the earliest
data in the memory. This is determined by the Memory Mode
setting in the Comms/Tracer menu—see Choosing what
happens when the memory is full in Chapter 3 section 1.
Ending the capture session
You can stop capturing at any time after the call has cleared.
-1-
From the main Simulate menu, select
Capture/Review.
-2-
Select Stop Session.
Reviewing a captured session
You can retrieve the captured protocol information and
display a simple decode on screen.

auroraSonata Hand Held ISDN Tester—User Guide
Note
The Real Time option is not removed from the menu, because
it is not a stored session—it always shows the most recent 8
kilobytes of information.
Saving the decode for a monitor session
The protocol information captured during a line monitoring
session is essentially the same as the information captured for a
test call in Simulate mode, except that you access it from
different menus.
For more information on saving and retrieving protocol
information for line monitoring, see Chapter 5.
Saving the contents of the real time buffer
auroraSonata holds the most recent 8 kilobytes of protocol
information in a part of its memory called the ‘real time
buffer’.
When you are capturing information for a test call in Simulate
mode, you can save the current contents of the real time
buffer in auroraSonata’s memory for future reference. This is a
useful ‘fallback’ if, for example, a network problem arises
when you have not set auroraSonata to save the protocol
information to memory or send it to the serial port.
Note
In both Simulate and Monitor mode, you can view the current
contents of the real time buffer to see recent protocol events.
See Viewing the real time buffer contents in section 1.
You can save the real time buffer contents at any time after
disconnection.

Analysing the
Decode Display
This section explains each of the possible formats for the
protocol decode.
Note
The section does not cover protocol analysis using auroraExpert
for Windows, because full user instructions are provided in the
auroraExpert for Windows Reference Guide and on-line Help.
The simple decode
auroraSonata displays a simple protocol decode on-screen during
all simulation test calls and line monitoring sessions. You can
also display a simple on-screen decode for information which
has been saved to memory, or for the real time buffer contents.
The example screen below shows the simple decode of a
section of protocol information captured to memory during a
test call in Simulation mode and now being reviewed.
About the display screen
At the top of the Decode window is a Status bar showing the
types of device which are connected to each other. The
example above is a typical display for a call between a TE and
an NT. The left side of the screen shows TE activity and the
right side shows NT activity.

Understanding the simple decode
The simple decode shows basic information about Layer 1,
Layer 2 and Layer 3 events, with a timestamp at the top right
of the screen.
The direction of each message is indicated by an arrow. For
example, in the illustration on the previous page a Connect
message has been sent from the NT to the TE.
For a Basic Rate link, the display shows Layer 1 Info states for
the Basic Rate S interface, Layer 2 frame messages (SABME,
UA, RR, etc), and Layer 3 messages. For a Primary Rate link,
instead of Layer 1 Info states the display shows Layer 1 alarms
as they occur.
Extended Decode
The extended decode display allows you to look at a message
that is displayed in the Decode window in more detail.
You can use the extended decode display when:
•
you are reviewing a monitor or capture session
that you have stored in auroraSonata’s memory
•
you are viewing the decode window for a call
that is connected

The detailed decode
auroraSonata can send a more detailed decode of the protocol
information to the serial port. From the serial port you can
send the decode to a printer or PC file.
You can choose whether to produce the decode in a standard
format (Decode) or in a format compatible with auroraExpert
for Windows (Expert). For instructions, see the earlier
sections of this chapter.
Initial output at the serial port
The standard output at the serial port begins with information
identifying the software release, current date and time, the
source of the decode (e.g. TE or NT), the protocol in use and
the current setup of auroraSonata.

25/07/00, 11:40
auroraSonata Hand Held ISDN Tester—User Guide
Understanding the standard decode
The standard decode shows the name of each message, with a
timestamp and the direction of the message. It decodes all
incoming and outgoing ISDN messages and Layer 1 events.
The output is in the form of a Layer 2 and Layer 3 partial
decode of the protocol information, with the message
information broken down into Layer 2 and Layer 3 parts.
The Layer 2 decode is displayed first, followed by the decode
of the Layer 3 part of the message, if there is one. Finally,
there is a hexadecimal print of the entire message.
For a Basic Rate link, Layer 1 Info State information is
provided by the S interface for the standard decode output.
For the 2B1Q U interface, the decode provides EOC and
FEBE/NEBE information. For a Primary Rate link, Layer 1
alarms are shown.
Decode output—Example
The tables on the following pages show a typical protocol
decode for the beginning of a call setup on a Basic Rate link.
The first table shows the initial output, which displays the
software release, current date and time, the source of the
decode (e.g. TE or NT), the protocol in use and the current
setup of auroraSonata.

Understanding the Debug output
The Debug format for the protocol decode is normally only
used for detailed analysis by Agilent Technologies engineers. It
consists of a hex printout of any transmitted or received
messages, plus additional information about the messages
(primitives) which are passed between the OSI Layers, internal
entities and the line at each end of the link. The layers are
labelled as follows:
MMI

This chapter describes how to operate auroraSonata from external
power or rechargeable batteries. It includes instructions for
recharging and replacing the battery pack.
Using external (mains) power
You can power auroraSonata from the mains supply, using the
adaptor/charger supplied with the unit. When you connect the
adaptor/charger, this automatically starts up a battery charging
cycle—see Recharging the battery pack later in this chapter.
-1-
Plug auroraSonata’s power supply unit into a
nearby power socket which is easily accessible.
-2-
Fit its connector into the external power
supply socket on auroraSonata, as shown below.
-3-
Switch on the mains power supply.
Note
You can also power auroraSonata from the 12V cigar lighter
adaptor in a vehicle, using a vehicle cigar lighter power cable
which is supplied as an optional extra.

Power Sources
Using battery power
auroraSonata is supplied with a removable, rechargeable nickel
metal hydride (NiMH) battery pack. The packs come in two
sizes—see Chapter 9 section 1 for details.
Warning: Battery packs
The battery packs are factory-sealed and must not be opened.
Battery life
The battery life depends on the interfaces you are using, the
age of the battery, surrounding temperature and the task you
are performing.
Under normal conditions, with one BRI S interface in use:
•
the medium capacity battery pack lasts up to 8
hours from fully charged
•
the higher capacity pack lasts up to 18 hours
from fully charged
PRI operation consumes significantly more power than BRI
operation.
Checking the battery voltage
When the battery is in use, auroraSonata displays a percentage
figure on the top level menu to indicate the battery condition.
For example:
Issue 2 - 07/00
Chap08.P65
8-3
3
25/07/00, 11:47
auroraSonata Hand Held ISDN Tester—User Guide
Note
Use this figure as an approximate indication of battery
condition. Immediately after charging, it is around 100%.
When the charge is adequate, it is around 60% (this varies
according to surrounding temperature). This value is displayed
during most of the charging cycle.
When battery power is low
When battery power has dropped to approximately 16% of its
fully charged voltage, the Bat LED flashes red. You must now
either recharge or replace the battery pack.
Note
If battery power falls to a level which is insufficient to power
the tester reliably, auroraSonata switches itself off. The system
settings are stored in the memory.
Saving the batteries
auroraSonata can be set to switch itself off automatically when
powered from batteries, if no calls are in progress and no keys
have been pressed after a certain length of time.
You can choose the length of time that auroraSonata will wait
before switching itself off, or disable the battery-saving feature
for continuous operation. For details, see Setting the
automatic power-off time delay in Chapter 3 section 1.
Discharging the battery pack
NiMH cells exhibit a ‘memory’, which means that if you
repeatedly recharge a battery which is only partially
discharged, a small amount of its capacity is lost.
This should not normally be a problem, but you may wish to
discharge the battery completely before recharging it. You can
do this by operating auroraSonata from battery power with the
battery-saving feature disabled (see above), or by leaving the
unit in unattended mode (see Chapter 6 section 2).

Recharging the battery pack
Warning: Recharging the battery
Only recharge the rechargeable NiMH battery pack supplied
with your auroraSonata.
You must not recharge the battery if the temperature is below
0°C or above +35°C.
-1-
Plug the power adaptor/charger into the mains
supply and auroraSonata’s power supply socket.
Warning: Using the adaptor/charger
auroraSonata is intended for use only with the adaptor/charger
with which it is supplied. If you use any other adaptor/charger,
you may damage the tester or battery, and invalidate
equipment warranties and approvals relating to safety or
electromagnetic compatibility.
The battery is initially charged at a high current (‘fast
charging’). This means it will be almost fully charged in 1-1½
hours (medium capacity pack) or 2-3 hours (higher capacity
pack). During fast charging, the Bat LED lights up green.
Tip
You can use auroraSonata while the battery is recharging. You can
also disconnect the adaptor/charger at any time during the
charging cycle: when you reconnect, a new cycle begins.
-2-
Continue until the battery is fully charged.
When fast charging is complete, the Bat LED glows green less
brightly. The battery is now being charged in ‘pulses’. This is
the ‘top off’ stage, which ensures that the battery is fully
charged: it lasts for 1½ hours (medium capacity pack) or 3
hours (higher capacity pack).
When charging is complete, the LED glows green very dimly,
to indicate that the battery is being ‘trickle charged’.

25/07/00, 11:47
auroraSonata Hand Held ISDN Tester—User Guide
When the battery is fully recharged, it is safe to leave the
charger connected for longer periods. If you do this, it
continues ‘trickle charging’ the battery to maintain full
capacity, and the Bat LED glows green very dimly.
Note
Avoid ‘force charging’ auroraSonata by repeatedly removing and
inserting the charger—this may cause excessive heat in the
tester and reduce the capacity of the battery.
Replacing a battery pack
It may be useful to carry spare battery packs with you, in case
the battery runs out at a site where no mains power is
available. Keep them in the carrying case until needed.
While you are replacing the battery, the real time clock and
system settings are maintained by a memory backup capacitor.
This should ensure that the settings are retained even if
auroraSonata is left without a battery for several hours.
To remove the old battery
-1-
Remove the battery pack cover, which is on the
back of auroraSonata. To do this:
•
Loosen the screw by turning it anticlockwise
using a coin or screwdriver.
•
When the screw is completely released, it pops
up. Slide the cover upwards to remove.

auroraSonata Hand Held ISDN Tester—User Guide
-3-
Replace the battery pack cover:
•
Slide the cover back down into place—be
careful not to trap the connector wires.
•
Push the screw down and turn it clockwise to
tighten.
Warning: Tightening the screw
Make sure the screw is properly tightened—otherwise the
cover will come off when you hang auroraSonata from its belt
hook.
Disposing of the old battery
Dispose of batteries in accordance with local environmental
regulations. Please recycle them wherever possible.
Warning: Disposing of batteries
Do not dispose of batteries in a fire—they may explode.
Storing the battery packs
If your auroraSonata is to be left unused for more than three
months, you should remove the battery and store it separately,
to avoid chemical changes caused by the discharge of the
internal circuitry.
For maximum life, batteries should be stored in a cool dry
place. The surrounding temperature must not exceed 30°C.
Note
When an auroraSonata battery has been stored for a long period
of time, it may be necessary to perform three or four complete
charge/discharge cycles to recover its full capacity.
Using auroraSonata without a battery pack
It is quite acceptable to use your auroraSonata without a battery
pack. However, if you plan to do this, remember that the
internal clock and system settings are maintained by the
memory backup capacitor for only a few hours. You are
advised to keep a note of the system settings.

Notes for
Purchasers
This section provides information to help you make decisions
when purchasing optional equipment for use with auroraSonata.
Customising your auroraSonata
As explained in Chapter 1, auroraSonata can be fitted with a
number of different optional interface modules.
The main advantage of this is that you can customise your
unit, using only those interfaces that meet your organisation’s
specific requirements. This means that:
•
the overall cost of the tester is lower, because
you only need to purchase the interfaces that
you actually need
•
if your requirements change, you can arrange
for additional interfaces to be fitted
•
the tester can easily accommodate future
developments
When you first purchase auroraSonata, you specify which
interface modules you require. Each module that you choose is
fitted onto the main unit by Agilent Technologies. Once fitted,
it is an integral part of the tester.
Your local sales representative can advise you on how to
proceed with upgrades.
Warning: Interface modules
Any future upgrades will require special handling. Do not
attempt to remove an interface module from the tester
yourself, unless you have been specifically authorised byAgilent
Technologies to do so.

This Appendix explains the Cause Codes generated by the
network (external codes) or auroraSonata itself (internal codes)
to explain why a call has failed, cleared or been disconnected.
External codes
The following codes are generated by the network at the
exchange to which your equipment is connected.
ETSI external codes
1
Unallocated (unassigned) number
The destination that the caller requested cannot be reached
because, although the number is in a valid format, it is not
currently assigned (allocated).
2
No route to specified transit network
The equipment has received a request to route the call through
a network which it does not recognise—either the network
does not exist or it does not serve this equipment.
3
No route to destination
The destination that the caller requested cannot be reached
because the network through which the call has been routed
does not serve that destination.
6
Channel unacceptable
The last identified channel is not acceptable to the sending
entity.
7
Call awarded & being delivered in established channel
The incoming call is being connected to a channel already
established to the user for similar calls, (e.g. packet mode).
16
Normal call clearing (peer)
The call is being cleared at the request of one of the users
involved in the call.

17
User busy
The called user cannot accept another call, although their
equipment is compatible, because there are no resources
available.
18
No user responding
The called user is not responding with either an Alerting or a
Connecting indication within the allowed period of time.
19
No answer from user (user alerted)
The called user’s equipment has responded with an Alerting
indication, but no Connecting indication has been received
within the allowed time.
21
Call rejected
The equipment will not accept this call, although it is not busy
or incompatible.
22
Number changed
The called number is no longer assigned.
26
Non-selected user clearing
The called user has not been awarded the incoming call.
27
Destination out of order
The requested destination cannot be reached because its
interface is not working properly. This may be because a
signalling message could not be delivered to the called user
(e.g. due to a physical or data link failure off-line), or because
the called DN has been manually placed in timer busy state.
28
Invalid number format
The called number is invalid or incomplete.
29
Facility rejected
The network cannot provide the requested facility.
30
Response to Status Enquiry
This cause is included in a Status message which has been sent
in response to a Status Enquiry message.
31
Normal, unspecified
This cause is used to report normal events only when no other
cause in the ‘normal’ class applies.

Introduction to ISDN
This chapter provides an overview of the Integrated Services
Digital Network (ISDN).
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 all 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 which the
user accesses either at an ISDN interface or a terminal
connected to the ISDN. The diagram below summarises the
services offered:

Appendix 3—Introduction to ISDN
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:
ISDN interfaces
An interface (‘reference point’) is said to exist between each
piece of equipment on the ISDN.

auroraSonata Hand Held ISDN Tester—User Guide
auroraSonata can be configured with interface modules for Basic
Rate testing at the S, U and T interfaces, or Primary Rate
testing at the S and T interfaces, provided the physical
interface is compatible.
ISDN standards
ISDN is subject to standardisation by the ITU-T, which issues
recommendations 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 sampling rate is 8kHz, and the sample value is translated
into an 8 bit code, to conform with ITU-T standards.
Therefore each speech signal results in a continuous bit stream
at a rate of 64kbps.
The process of converting between analogue and digital is
known as encoding. An encoding device 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: 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.

Appendix 3—Introduction to ISDN
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 techniques: each one involves
coding digitised speech into different voltages which can then
be transmitted down the telephone lines.
Basic Rate and 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.
The B channels contain user data at rates of up to 64Kbps.
The data is switched by the network to provide an end-to-end
transmission service.
The D channel carries control and signalling data at 16kbps
(Basic Rate) or 64kbps (Primary Rate). It may also be used for
X.25, the Packet Switched Network.

Basic Rate
Basic Rate (BRI) consists of two B channels and one D
channel, known collectively as 2B+D.
Basic Rate access to the ISDN
The diagram below illustrates Basic Rate ISDN operation.
In this illustration, a 4 wire bus consisting of a transmit and
receive pair (known as the ‘S bus’), is connected to the NT1.
The S bus is terminated at the NT1 and the distant end, on
both the transmit and receive pairs. Connection to the bus is
usually made via 8-pin plugs which conform to ISO
Specification 8877. Over this bus pass the 2B+D channels.
Point-to-point and point-to-multipoint links
The S bus can operate in either point-to-point (PP) or pointto-multipoint (PMP) mode.
•
On a PP link, one TE is 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
mains failure, a basic telephone service is still provided.
Primary Rate
There are two variations of the Primary Rate Interface. In
Europe, primary rate comprises of 30 B channels and one D
channel, known collectively as 30B+D. In the U.S., the
primary rate standard comprises of 23 B channels and one D
channel, known collectively as 23B+D.
B Channels
The B channels contain user data at rates of up to 64kbps.
D Channel
The D channel is reserved for control and signalling data at
64kbps.
Primary Rate access to the ISDN
The Primary Rate Interface is point-to-point only; the
connection is simply between the network and a PABX or
similar piece of equipment. The line carrying the traffic is
either a 75 Ohm co-axial, a 120 Ohm twisted pair or a fibre
optic cable.

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 Physical layer—transmits bits between the
terminal and the network. Defines connectors,
line coding, transmission rates and anything else
concerning the transfer of bits.
Layer 2 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 Network layer—routes messages to their
destination.
Layer 4 Transport layer—the end-to-end layer which sets
up and maintains connections.
Layer 5 Session layer—handles the co-ordination between
processes.
Layer 6 Presentation layer—provides data formatting and
code conversion.
Layer 7 Application layer—this is the task to be
performed, e.g. remote login and file transfer.

Basic Rate Layer 1 S bus operation
Layer 1 transfers information in frames across the S bus
between the terminals and the NT1.
Each 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, plus bits for channel D and other functions.
D Channel Contention
If two TEs attempt to make a call simultaneously, a procedure
known as D Channel Contention prevents a collision.
Activation and deactivation
TEs and NTs can be deactivated 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 4
NT to TE—contains operational data.

Layer 1 Frame Structure
Data is transferred across the line in ‘layer 1’ frames. In
Europe, each frame is 256 bits in length and lasts for 125
microseconds. In the U.S., each frame is 193 bits in length and
lasts for 125 microseconds.
The structure of the European frame is shown below:
Layer 2
Layer 2 provides a secure, error-free connection for Layer 3
call control information, by organising the Layer 3 bits 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 terminal to which it refers. Contains a SAPI
to identify the service for which the frame is
intended, a TEI to identify the terminal and a
Command/Response bit.
Control
Carries information that identifies the frame.
Information Carries the signalling or layer 3 message.
FC Sequence Used for error detection.

Siemens. There are two implementations:
•
CorNet-N operates between adjacent PBX links.
•
CorNet-T operates between a PBX and a piece of
ISDN Terminal Equipment (TE).
CorNet-N and CorNet-T are based on the ETSI protocol.
When CorNet-T is selected auroraSonata can only emulate a TE.
TN1R6-N & TN1R6-T
TN1R6 is a private ISDN protocol that was developed by
Bosch Telekom.
•
TN1R6-N operates between adjacent PBX links.
•
TN1R6-T operates between a PBX and a piece of

Parity
A mechanism for determining whether a single bit error
has occurred when individual characters are being
