COMMANDER INTRODUCTION

INTRODUCTION

Thank you for buying a Tieline technology codec!

In the audio codec broadcast revolution Hearing is believing….

Tieline, providers of the world’s best Plain Old Telephone Service (POTS) Codec
technology, developed the COMMANDER codec to provide high quality, bi-directional
audio for POTS together or ISDN operation.

Tieline has changed the opinions of even the most critical broadcasters, proving that
stable high bandwidth links with unfailing audio and data is the new reality for
broadcasting over a telephone line.

A superb DSP algorithm delivers crystal clear 15kHz bi-directional audio in real time at bit
rates as low as 24kbps with a small 100ms delay and a minimal loss of quality over a
standard telephone line.

COMMANDER is the versatile CODEC solution, giving you full broadcast freedom with

the ability to use ISDN if required. COMMANDER is part of the Audio Codec Family that

includes the PATRIOT – the economical solution and i-Mix – the Sportscasters Dream

Machine.

COMMANDER provides audio-link opportunities previously that were impossible or
simply too expensive to use. Broadcast journalists and presenters now have an easy to
use compact portable field codec with high quality, two-way audio link performance.
COMMANDER can be transported as carry-on baggage allowing convenient worldwide
coverage with minimal equipment or is available as a professional Studio rack mount
unit.

Using the COMMANDER is as simple as plugging it into a POTS (Plain Old Telephone
Service) or ISDN (optional extra) phone line and dialing the destination number. The
receiving Tieline codec automatically answers the call and establishes the link. For POTS
connections, a built-in modem negotiates the best possible data rate for high-quality low­noise and distortion, bi-directional audio.

COMMANDER features include:

• High quality audio at very low bit rates

• ISDN as an optional extra

• Many remote control features for remote operation

• Purpose built modem for POTS codec operation

• Automatic link re-connect in the event of line dropouts

• Extensive menu system caters for most individual applications

• Choice of optional extras such as;

o 15kHz audio in one direction and up to 9600bps in the opposite direction

OR
o 7kHz audio and up to 4800bps of data simultaneously in both directions

• Fast and easy configuration via a Windows 9*/ME/2K software application:

COMMANDER INSTALLATION AND USAGE TIPS

INSTALLATION AND USAGE TIPS

While the TIELINE COMMANDER is a very reliable telecom product, its performance will only be

as good as the line that it is operating over.

Proper precautions MUST be taken to ensure that only the COMMANDER uses the line.

Remove these possible interference sources:

• Other telephone handsets

• Fax machines

• Computer modems

• Alarm systems

• Extension bells

• Line monitoring devices

Important precaution for the COMMANDER phone-line:
ENSURE THAT CALL WAITING IS DISABLED!

It is always preferable to obtain a dedicated phone line from the local Exchange or Central Office.
Try to avoid going through a PBX, PABX, Key station or any other local exchange. If this is
unavoidable, check that the line works BEFORE you try to do a live program. Some of these
systems have poor line characteristics and may make the operation of the COMMANDER
marginal, if not unusable.

WARNING - DO NOT CONNECT YOUR TIELINE TO A DIGITAL PHONE SYSTEM AS
PERMANENT DAMAGE MAY OCCUR.
If you are unfamiliar with a particular facility, check that the line you are given is NOT a digital
line. This is very important. because If the unit becomes faulty due to the use of a digital phone

system, the Warranty automatically becomes void.

On most good lines, the COMMANDER is normally able to achieve 28,800 bps (Bits Per Second)
at a line quality of approximately 70%. If you are not able to achieve this level of operation, you
may have transmission problems with your line or the line at the other end of the connection.

CHECK:

• Length of the line from your site to the local Exchange or Central Office

• Presence of stub or party lines on your local loop

• Earth leakage problem on the line

• Equipment problem at the Exchange or CO

It is very desirable to have a local loop (The line from your office or home to the local CO or
Exchange) as short as possible. Optimum performance can be expected for lines up to about
three kilometers in length.

In some countries, it has been the practice to have more than one phone service attached to one
line. As more lines have been installed, the services have been separated but the unused lines
have remained connected to the local loop. Even though the old line may be unused, if it is still
present across your local loop, it will cause problems with your equipment operation.

A good line should have an earth isolation of better than ten meg-ohms. If your line is located in
an area where water is a problem, check out the earth leakage.

Although there are many factors at the Telco end that can cause problems, a problem that does
occasionally occur is if the clock on the interface codec to your line is not synchronized to the
network. A drifting clock will cause instability and unreliable COMMANDER performance. If you
suspect that this could be the problem, contact your local Telco.

Dialing a number

Here’s how to make a connection from one COMMANDER to another using a standard Plane Old
Telephone Service (POTS) telephone line. Connect the telephone line to the modular socket at
the rear of the COMMANDER. Switch on and wait for the self-check functions to complete.

The COMMANDER will dial the number to establish a connection with the remote TIELINE Codec
equipment at an initial attempt of 19,200 bps bit-rate. The modems measure the characteristics of
the telephone line and then negotiate the highest possible stable data rate for best sound quality.

Dialing From an Office or Hotel Room

Most hotels and offices require dialing an additional digit(s) followed by a pause to gain access to
an outside line. After entering the access number, hold the “#” key until a comma (“,”) appears
after the access number on the LCD display. Now enter the rest of the telephone number. A two
second pause has now been inserted after the access digit to allow time for the outside line to be
set up for dialing. The length of this pause can be changed in the “View Config” menu.

FUNCTION KEYS

Quick Function Tips

The CLEAR Key is a general Escape (Esc) key. Selecting the CLEAR Key takes you back to the

previous screen from the particular menu that you are in.

Many COMMANDER menu items can be quickly accessed by pressing either the F1 or F2 keys
followed by a single number (0~9).

A common set of items are installed as defaults and can also be reinstated through the “Reset
Function” in the menu system [Menu 09]. The default key settings provide a useful tool for the
operator.

The Keys can be tailored to individual requirements through the [07 Advanced Setup] menu and
its sub-menu option [06 Function Setup]. The Toolbox PC application (page 38) can also set the
function keys and save these settings as a data file for later reuse.

F2 & KEY 6 Retrain Current

COMMANDER modems communicate over the line to establish the best possible conditions
for data transmission. The modems “train” the line to compensate for variations in frequency
response and to cancel out any echo that may be present. Under some circumstances,
particularly when line conditions are subject to change, it may be beneficial to manually
request the modems to "retrain" the line by using F2 & KEY 6. The audio is muted for about 20
seconds during this process.

F2 & KEY 7 Toggle PPM Meter

Changes the Peak program meter to display either the incoming or outgoing audio level.

F2 & KEY 9 Renegotiate Down

Manually requests COMMANDER modems to renegotiate a lower bit rate.

Note: This should be done when current line conditions no longer support the prevailing bit

rate. This is indicated by audible disturbances such as "popping" noises or distortion. The
audio is muted for about 1 second during the renegotiation process.

COMMANDER HOW THE COMMANDER WORKS

©Tieline Technology - 34 - August 2002

HOW THE COMMANDER WORKS

Analogue audio inputs (two) are combined and amplitude limited prior to being digitized by a high
quality stereo 20-bit analog-to-digital converter. The serial data bit stream is then fed to an
extremely fast 32-bit DSP that encodes the audio data using the proprietary digital audio
compression algorithm.
After compression, the DSP then produces a low bit rate serial data stream that is fed to a V.34
data modem.

At the remote TIELINE Codec, the reverse process takes place. The audio data is decompressed,
fed to a digital-to-analogue converter, then amplified to line level and fed to a balanced output
connector for broadcasting.

ISDN operation is very similar to the POTS operation except that a fixed bit rate of 64kbps or
56kbps (US network) is used. The quality of sound at ISDN bit rates is near CD quality and the
delay is a relatively low 100 milliseconds.

Theory of Operation

Coding Algorithms

Over the past two decades, there have been great improvements in the way that digital audio data
can be condensed while retaining much of the quality of the original signal. Many different
algorithms have been developed, including well-known ones like MPEG layer 2 and 3. These
algorithms require a reasonably high bit rate, typically 64kbps or higher, for high quality wide band
mono real time operation. Many ISDN codecs use MPEG layer 2 and 3 for mono communications
at 64kbps and 128 kbps however the delay can become a problem for real time operation. Some
codecs use MPEG-2 layer 2 and 3 to overcome bandwidth limitations at low bit rates.

While the MPEG algorithms may be suitable for ISDN operation, they are quite inadequate for the
low bit rates available for POTS operation. Some manufacturers have tried to use MPEG for low
bit rate POTS operation but have found the results less than satisfactory. As a typical POTS line
will achieve bit rates of 28,800 or less, an algorithm capable of far greater performance than
MPEG is required.

Fortunately, significant advances in the development of coding algorithms have made the design
of digital audio codecs like the COMMANDER possible. The proprietary coding algorithm used by
COMMANDER achieves compression factors of the order of twenty times or more.
This enables 15 kHz bandwidth high quality audio to be transported at a bit rate as low as
24,000bps. Reduced quality and bandwidth can be obtained at bit rates down to 9600bps. In
addition, low coding delays of 100 milliseconds provide the kind of performance required for real
time operation.

Peak Level Meter

The LCD provided on all COMMANDERS shows the peak audio levels being transmitted.

COMMANDER HOW THE COMMANDER WORKS

©Tieline Technology - 35 - August 2002

Modem Negotiation and Line Quality

COMMANDER sends and receives high-speed digital information over a standard telephone line
via an internal modem. The modems communicate over the line to establish the best possible
conditions for data transmission and the highest reliable data rate. This also corresponds to best
possible audio quality.

Initially, the modems “train” themselves to the line to measure and compensate for variations in
frequency response and to cancel out any echo that may be present. The modems then establish
the highest possible speed for data transfer using a process of “negotiation” with each Data
Pump.
When the modems have established the connection, control is passed to the COMMANDER CPU
and the LCD will display the Line quality (LQ). Generally, for satisfactory operation, LQ needs to
be greater than 30%. LQ of 70% or more is excellent. One of the unique features of the
COMMANDER is to show the LQ for both the Local (L) and the Remote (R) units. This valuable
information enables the user to manage the link more effectively.

Refer to Menu 03 Modem Setup in the Detailed Configuration section for more information on

retraining and renegotiation the bit rate.

Master Slave Operation

A unique feature of the COMMANDER is the remote control capability of the unit for audio input
level control. All TIELINE Codecs can be set up so that the input level can be controlled from a
remote site, such as a studio or control center. This enables a TIELINE Codec to be used by non­technical people or to be unmanned. All the levels can be monitored and adjusted from the control
center by using a master COMMANDER.
In most applications, the COMMANDER located in the studio or control center is set up as the
Master unit and a TIELINE Codec at the remote location is set up as the Slave unit.

The easiest way to do this is with the Quick Function keys F2 - #. By pressing these two keys, one
after the other, it will sequence through the different modes of operation. The first sequence sets
the COMMANDER in Master mode. Pressing the keys again puts the unit in Slave mode.
Pressing the key sequence again sets the unit into Toolbox mode and the final sequence puts the
unit back into Local mode. Alternatively, the unit can be set up by using the Menu Selector and
selecting the Advanced Setup menu.

When a unit is set up as a Master, the Input gain controls operate the audio gain at the remote
TIELINE Codec. The input level for the local COMMANDER remains at the setting last used when
in Local mode. To adjust the local input levels, COMMANDER has to be set back into Local mode.

When a unit is set to Slave mode, the input level is set by the local Input controls until the TIELINE
Codec is connected to a Master unit. When the connection is made, the Slave TIELINE Codec
obtains the gain setting from the Master unit and it then stores the setting in memory. If the
Master COMMANDER is then switched to Local, as can be done with the Studio rack unit, the
Slave unit maintains the level last received from the Master unit.

COMMANDER HOW THE COMMANDER WORKS

©Tieline Technology - 36 - August 2002

ISDN Operation

SPID

Each telephone line is assigned a single directory number. When a customer orders services or
features they are programmed into a Service Profile stored at the switch. Any call associated with
that line can be assumed to apply only to that customers Directory Number and Service Profile.
When a single ISDN device is connected and serviced this way , the configuration is said to be
point-to-point.

However, ISDN also supports point-to-multipoint configurations, with multiple but dissimilar
devices connected to a single line. In many cases, it is not desirable to share the same directory
number and service Profile. Consequently ISDN relies on an initialisation procedure for
associating Service Profiles with individual terminating equipment, rather than lines. Terminating
equipment that support this procedure are said to be Auto Initialising.

The ISDN supplier gives the customer a Service Profile ID (SPID) of up to 20 digits long. The
customer programs the number into the terminating equipment which sends it to the switch. The
switch then associates the SPID with a specific Service Profile and Directory number. When the
switch sends setup messages to a point-to-multipoint line, only equipment with the matching SPID
will respond.

Relay Control

All Commander units are supplied with two CMOS relay control ports on the RS 232 Interface
Connector located on the rear of the unit. There is also an optional relay card that can be installed
in Commander rack units. A description of these relays and how they work is given below. These
allow a user to control an external piece of electrical equipment from the COMMANDER.

Port one and two can be used in two different modes;

Mode 1

• Port one is activated when a call is answered by the COMMANDER.

• Port two is activated when the link is established and audio is ready to be sent.

Mode 2

• Port one and two are controlled by Quick Function keys (see page 18)

CMOS Relay Ports

These are semiconductor devices that provide a circuit closure when they are activated. They are
rated to 350volts peak across the contact closure and they have a maximum current rating of 120
milliamps. The contact closure resistance is approximately 35 ohms. A circuit diagram outlining
the pin details are given on page 48.

Relay Card (optional)

A relay module fitted with six electro-mechanical relays is available as an option for the
Commander rack unit. A diagram of the interface connector is provided on page 37 of this manual.
These relays are activated by Quick Function keys on page 18 or via the Toolbox software on
page 38.

Relay Operation Modes

Both types of relays can be set to operate either in toggle mode or pulse mode. See Relay

Operation details on page Error! Bookmark not defined. for the details of each mode.

TOOLBOX Software

Toolbox is a PC compatible software application that works with the COMMANDER and provides
a convenient way to configure, remotely operate and monitor a COMMANDER system using a
Personal Computer. The application also provides online “chat” and communication diagnostic
tools.

Updates can be downloaded from the Tieline web site;

http://www.tieline.com.

Obtain the free, latest version.

Preparing to use the ToolBox application

The Toolbox software is distributed as a compressed file “TieTool.zip”. Extract the program files to
the PC hard drive using a program such as WinZip 8. The files are;

• TieTool.exe - TieLine toolbox application

• Tietool.hlp - Toolbox help file

Both of these files should be saved in the same directory or folder.

Connecting COMMANDER to the PC

The COMMANDER serial port connects to any vacant serial (or COM) port on the PC using a
standard modem cable. A cable can also be constructed using the following components and
connections:

COMMANDER (DB 9
