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 low-

noise 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.
