RoadRunner USERS GUIDE

standard G.722 codec. When connecting to a PKI telephone, you must

select either NEWPKI or OLDPKI, depending on the age of the

telephone. You will only be given this choice if G.722 is selected as the

algorithm at 64 kb/s.

EXAMPLE 1 - QUICK SETUP OF ENCODER AND DECODER

For this example, we will configure the RoadRunner for MPEG Layer 2

operation at 128 kb/s, with 24 kHz sampling. We will be connecting to

another RoadRunner, thus using a decoder independent ‘NO’

configuration. Following the procedure below, you can configure your

RoadRunner with any algorithm, bit rate and sample rate combination

in a like manner.

First, use the arrow keys to highlight <Operation>, press ENTER

Select desired algorithm, <MPEGL2>, press ENTER

Select <Setup Seq>, press ENTER

Select the desired sample rate, <24>, press ENTER

Select the desired bit rate, <128>, press ENTER

Select two-line operation, <L1L2>, press ENTER

This completes the configuration of your RoadRunner.

Quick Status

The RoadRunner offers a status screen that enables the user to confirm

the current configuration at a glance. The status screen, an example is

shown here, is accessed by pressing the F1 button or by using the

keypad sequence:

The top line shows the selected encoder algorithm (which may be

different from the decoder algorithm), the sample rate and the decoder
