The Session
Whether manually, or using CDQPrima’s pre-programmed
Quick Configurations or Speed Dials, getting configured and
connected couldn’t be easier
6. Two Steps To Success
A
ny ‘session’, whether just a few seconds or a permanent
connection, requires some pre-negotiation with the user at the
other end regarding the best possible configuration to use. In
most cases, the application will determine the best
configuration, but in a few cases, cost or transmission medium will
determine the configuration.
Once configured, as outlined in section 6.1, the only thing left to do is
connect to another codec, discussed in section 6.2, beginning on page 622.
6.1 Go Configure
Once you have decided on the configuration to use, setting your
CDQPrima is as simple as following a few prompts. But first, some
discussions on the various modes available:
6.1.1 Codec Compression Algorithms and Modes
There are currently three coding algorithms used in the CDQPrima.
Each has its advantages and disadvantages. Which algorithm you use
depends on a number of factors, including desired audio quality, delay,
cost, and compatibility with other codecs. This chapter serves as a
guide for choosing the best algorithm and mode for your applications
when a choice is available.

6.1.1.1 Stereo and Dual Mono
Users have expressed a great deal of confusion concerning the
differences between stereo, dual mono and joint stereo. From a coding
and compression standpoint, stereo and dual mono are identical. That
is, half of the total bits are assigned to the left channel, and half of the
total bits are assigned to the right channel. Left is always left, and right
is always right…no blending, no sound stage manipulations.
6.1.1.2 Joint Stereo
Unlike dual mono or stereo, joint stereo employs real-time bit allocation
techniques and dynamically assigns bits to the channels and frequency
bands that need them the most. Bits are allocated to the channel and
frequency bands that need them on a frame-by-frame basis. This
dynamic bit allocation results in considerably wider bandwidths and
higher signal-to-noise ratios than possible with the fixed bit allocation
of the other modes. If the bit allocation circuitry determines that
enough capacity is available for true stereo, then stereo frames will be
sent.
Unlike stereo and dual mono, joint stereo may manipulate the left-right
sound stage and stereo separation at high frequencies. The infinite leftright sound stage is blended into seven locations at high frequencies
should the bit allocation circuitry deem it necessary. However, it has
been shown that any spatial blending performed by the bit allocation is
in frequency bands where the human auditory system would normally
blend stereo signals. This is one of the basic premises behind
psychoacoustic modeling. A detailed discussion of joint stereo bit
allocation techniques can be found in the CDQPrima Technical
Reference Manual.
After rigorous testing with trained listeners, joint stereo audio has been
determined to yield higher perceived audio quality than stereo or dual
mono at low bit rates, such as those encountered with single ISDN
lines.

Different, high fidelity left and right audio programs
ISO/MPEG Layer III can deliver full duplex, 15 kHz monaural audio
using only one 56 or 64 kb/s ISDN ‘B’ channel. At 112 or 128 kb/s,
transparent 20 kHz monaural audio is possible. Near-transparent 20
kHz audio is possible in joint-stereo mode. In dual mono or stereo
modes, near-transparent 15 kHz audio is obtained.
Although Layer III offers a wider bandwidth than other algorithms at
low bit rates, the inherent drawbacks of this algorithm may outweigh
this benefit. The disadvantages of using Layer III are long coding delay
times and poor cascading ability. In addition, audible artifacts may be
noticeable when using Layer III at lower bit rates, and post-processing
may further degrade the audio.
At 112 or 128 kb/s, the only advantage of using Layer III over
MUSICAM-enhanced Layer II is that Layer III can deliver true stereo
with 15 kHz bandwidth. This makes Layer III ideal for mix auditioning
or other applications where high fidelity and true channel separation
are required, since no sound-stage manipulation is employed. Other
than that, at 112 or 128 kb/s data rates, we recommend using Layer III
only when communication with Layer III-only codecs is required. Even
at 112 or 128 kb/s, digital artifacts may be noticeable, and the delay,
cascading and post-processing limitations are still present.
At bit rates higher than 128 kb/s (not supported with internal terminal
adapters), there is no advantage to using Layer III over MUSICAM or
standard Layer II. Bit rates up to 320 kb/s are supported for
compatibility.
6.1.1.4 MUSICAM and ISO/MPEG Layer II
Recommended applications for MUSICAM-enhanced Layer II:
•
•
•
•
•
•
Studio-to-transmitter links
Voice-over
High-fidelity remotes
Different audio to two locations
Highest quality audio over ISDN
Low delay (single line mode)
The premier coding algorithm used in CDQPrima is MUSICAM,
MUSICAM USA’s enhancement to the ISO/MPEG Layer II encoding
algorithm. MUSICAM offers the best possible combination of fidelity,
6-3
Prima
CDQ
U S E R S
G U I D E
moderate delay and excellent transcoding ability at all bit rates.
MUSICAM encoding is fully compatible with all MPEG Layer II codecs,
and since the enhancements are a function of the encoder, any decoder
will sound better when connected to a CDQPrima.
MUSICAM can deliver full duplex, 10.2 kHz audio on one ‘B’ channel
with 24 kHz sampling. Although a narrower bandwidth at 56 and 64
kb/s than MPEG Layer III, the advantages are higher signal-to-noise
ratio, higher transparency, lower delay, less noticeable artifacts and
better results when transcoding and post-processing. In addition, the
CDQPrima allows you to send two different audio programs to two
different locating using this mode.
When using 112 or 128 kb/s, the CDQPrima delivers transparent, 20 kHz
monaural or joint stereo or 10.2 kHz dual mono audio. Recommended
for all voice-over work, MUSICAM Layer II at 128 kb/s, monaural, can
stand up to extensive post-production and can be re-coded several
times before artifacts become noticeable.
At bit rates higher than 128 kb/s, the CDQPrima delivers transparent
stereo with immunity to degradation even after up to 15 cascades (at
384 kb/s).
Please note that the CCSO and CCSN algorithms in the CDQPrima are
all MUSICAM algorithms, but these are used when connecting to early
CCS and MUSICAM USA products manufactured before MPEG Layer
II was standardized.
6.1.1.5 G.722
Recommended applications for G.722:
•
•
•
•
Sports, news, traffic and weather reporting
Call-in talk shows
Compatibility with G.722 codecs
Low-delay return audio for high-fidelity remotes
G.722 is one of the earliest audio coding algorithms to be standardized.
G.722 is a relatively simple algorithm based on ADPCM (adaptive
pulse code modulation) offering full duplex 7.5 kHz audio over a single
ISDN or Switched-56 channel. The key advantages of G.722 are its
compatibility with most other codecs and very low delay times. G.722
is ideal for situations where instantaneous talkback is required, such as
dial-in talk shows and distant interviews. The main disadvantages are
6-4
Prima
CDQ
U S E R S
G U I D E
the limited audio fidelity, poor signal-to-noise ratio and poor cascading
properties. G.722 is not recommended for music applications.
6.1.1.6 Algorithm, Mode, Bit and Sample Rate
Since no single algorithm/mode/sample rate/bit rate combination is
ideal for all applications, the CDQPrima offers several different
combinations, each with advantages and disadvantages. In addition,
the full range of available algorithms insures that your CDQPrima can
connect with the widest number of codecs. The tables below compare
the available algorithms and bit rates. Recommended algorithm
combinations are indicated with a ü. In some instances, especially at
lower bit rates, using a lower sample rate will result in better audio,
with wider bandwidths and reduced artifacts.

Other combinations of algorithm, mode, bit rate and sample rate are
possible, but not all combinations are valid. You should be careful when
using a remote control device since there is no check on parameter
validity when configuring through the remote control port. If you get
an error message such as “BAD TOGGLE ON…” or “INVALID
PARAMETERS”, it is because you have entered an invalid combination.
Refer to the CDQPrima Technical Reference Manual for valid bit and
sampling rate combinations.
Please remember that MUSICAM is a fully compatible enhancement to
the ISO/MPEG Layer II standard algorithm. Since the ISO standard
defines the encoded bit stream, and hence the decoder, all
enhancements are to the encoder. Therefore, when connecting to a
standard Layer II codec at the far end, the audio you hear will be Layer
II, but the audio heard at the far-end will be MUSICAM enhanced.
MUSICAM encoding makes any Layer II decoder sound better.
Layer III provides the widest bandwidth at low bit rates, up to 15 kHz
at bit rates of 56 or 64 kb/s. Layer III may be useful at these low bit
rates when wide bandwidths are required and connection costs are a
factor. However, even at high bit rates, Layer III has long delay, does
not cascade well and is adversely affected by post-processing. There is
no advantage to using Layer III over MUSICAM. In some applications,
Layer III may provide better audio than standard Layer II, but in most
applications, MUSICAM has been judged to be the superior algorithm.
6.1.2 Pre-Programmed Quick Configurations
Keeping in mind that Speed Dial entries contain all information
required to fully configure the encoder and decoder sections, Quick
Configurations are simply Speed Dial entries that do not dial. Since no
dialing is performed, you do not need to have an internal terminal
adapter to take advantage of Quick Configurations.

CDQ
U S E R S

Your Prima LT is shipped pre-programmed with nearly three dozen of
the most common configurations pre-loaded as Quick Configurations.
These pre-loaded configurations are held in the first Speed Dial table
entries. In some cases we have set the same parameters in two or more
entries. We did this to enable you to use the alphanumeric description
to configure to various devices without needing to know the details.
!note:
The best way to assure trouble-free communication with another
Prima LT or CDQPrima user is to both use the same Quick
Configuration. If both users have loaded the same configuration, and
the lines have been dialed correctly (appropriate bit rates), the
connection will work. It’s as simple as that. When connecting to a
MUSICAM USA RoadRunner, have the RoadRunner user speed dial
the ID number shown in the RoadRunner equivalent column on the
following table.
More Quick Configuration can be added at any time. Details on using,
editing, and creating your own Quick Configurations can be found later
in this chapter. If you do not find a pre-programmed configuration that
meets your needs, simply use the one that is closest, changing the
parameters that need modifying.
To use a Quick Configuration, simply speed dial the entry by pressing
the SDIAL button, enter the ID number and press ENTER. The following
entries have been pre-programmed, Note that 2-Line configurations
default to lines 1 and 2:
A pull–out Quick-Configuration table can be found at the
end of this chapter. We recommend that this table be
kept near the CDQPrima for quick reference.

6.1.3.1 Encoder Bit Rate
The CDQPrima offers several different combinations of bits and sample
rates. For G.722, Independent Mono modes or with a single-line
configuration with an internal terminal adapter, the only allowable bit
rates are 56 and 64 kb/s. For 2-line operation, only 112 and 128 kb/s is
6-12
Prima
CDQ
U S E R S
G U I D E
allowed. For MPEG operation in the 1-line mode with a non-TA Digital
Interface, you have a choice of all supported bit rates.
Select the encoder bit rate at the Bit Rate prompt or use the EBR
command from a terminal.
6.1.3.2 Encoder algorithm
The CDQPrima supports three basic algorithms, all of which are
described in detail in Section 6.1.
G.722 provides 7.5 kHz audio at 56 or 64 kb/s. MUSICAM enhanced
MPEG Layer II supports bit rates from 24 to 384 kb/s, depending on
Digital Interface Module used, and MPEG Layer 3 supports bit rates
from 56 to 320 kb/s, also depending on installed Digital Interface
module. Please note that CCSO and CCSN algorithms are both
enhanced MPEG Layer II algorithms but are used when connecting to
older CCS Audio Products codecs such as the CDQ1000 and CDQ2000
codecs that have not been upgraded to work with standard-compliant
MPEG Layer II encoders.
Select the encoder algorithm at the Algorithm display prompt
<Common><Encoder><Algorithm>
or use the EAL command from a terminal.
6.1.3.3 PKI Compatibility Mode (G.722 Only)
PKI telephones, manufactured by Philips and in wide use in Germany,
require a special frame structure, and your CDQPrima must be set
accordingly to interoperate with these telephones. If you are connecting
to a PKI telephone, select the G.722/H.221 mode from the Common menu
<Common><G.722/H.221>
or use the CGH command from a terminal.
6.1.3.4 Encoder Algorithm Mode
The next step (for MPEG algorithms only) is to select the algorithm
mode, Mono, Dual Mono, Stereo, or Joint Stereo. Select the desired
mode at the Algo Mode prompt or use the EAM command from a
terminal.
For G.722, the algorithm mode must be M1. Any other choice is an
error.

6.1.3.5 Encoder Line Format
Four line formats are available: Single Line (1 LN), uses only one of the
available lines. Dual Line (CCS 2 LN), uses inverse-multiplexing to
combine two available lines for 112 or 128 kb/s operation over ISDN or
other dedicated lines. H.221 (H221 6 LN) uses BONDING to combine up
to 6 lines (with internal terminal adapters) to achieve bit rates up to 384
kb/s over ISDN. Independent Mono (Ind. Mono) uses two or more
available lines to send different audio programs to two or more
different locations. The single line mode supports all available bit rates,
Dual Line supports only 112 and 128 kb/s. H.221 supports any multiple
of 64 kb/s, up to six. Independent mono supports only 56 and 64 kb/s

6.1.4.1 Decoder Independent Mode
Under normal operation when connecting to any codec manufactured
by MUSICAM USA or CCS Audio Products, the decoder should be
slaved to the encoder by selecting the ‘Independent NO’ mode. Under
certain circumstances, the decoder must be set to operate independently
of the encoder:
!note:
•
When connecting to any codec not manufactured by
MUSICAM USA or CCS Audio Products.
•
When using any of the Broadcast Modes described in the
Application Notes section of the CDQPrima Technical
Reference Manual.
•
When using the Independent Mono (Ind. Mono) mode for
sending two different monaural programs to two different
locations or receiving from two different locations.
•
When using different algorithms, bit rates or line formats for
send and receive audio.
The decoder independent modes also allow send and receive audio to
use different algorithms. For example, high quality audio can be sent to
another codec, but low-delay, lower quality return audio can be used
for cueing. The decoder must be set to independent YES when
connecting to other brands of MPEG Layer II and Layer III
compatible codecs.
This standalone (independent) mode can be used at any time; however,
there are certain times when the decoder should operate in conjunction
with the encoder, as listed above.
Use the DIN command from a terminal or make your selection from
the Indep prompt
<Decoder><Indep>
If decoder independent NO is selected, then the decoder is configured
exactly like the encoder, and the configuration is completed. If decoder
independent YES is selected, you must manually configure the decoder
section.
6.1.4.2 Decoder Line Format
The allowable decoder line formats depend on the algorithm selected.
For G.722, the only allowable line formats are Single Line (1 Ln) and
6-16
Prima
CDQ
U S E R S
G U I D E
Independent Mono (Ind. Mono). For normal operation with G.722, select
1 Ln, and for use when connecting to two different far-end encoders,
use Ind. Mono. If single line is selected, you must enter which line you
will be framing (connecting) to. If independent mono is selected, you
must enter which lines to use for the left and right channels.
When using any MPEG Layer II algorithm, Single Line (1 LN), Dual
Line (CCS 2 LN) and H.221 multi-line (H221 6 LN) modes are available.
The Single Line mode supports all allowed bit rates only when using a
non-terminal adapter type digital interface, otherwise, only 56 and 64
kb/s is supported. The Dual Line mode supports only 112 and 128
kb/s bit rates. H.221 line format allows connecting up to six ISDN lines.
To use BONDING to combine up to six ISDN lines into a larger pipe,
select (H221 6 LN) and enter the lines to use.
MPEG Layer III supports Single Line and Dual Line modes, with the
same restrictions as MPEG Layer II.
Select the line format at the Line Fmt prompt
<Decoder><Line Fmt>
or use the DLI command from a terminal.
6.1.4.3 Decoder Bit Rate
Under most circumstances, the combination of encoder bit rate, decoder
algorithm and line format will determine the allowable decoder bit
rate. The decoder bit rate must be a multiple of the base rate chosen for
the encoder. For example, if the encoder bit rate is 112 kb/s, the
decoder bit rate cannot be 64 or 128 kb/s because different base rates
(56 vs. 64 kb/s) are used.
Select the appropriate bit rate at the Bit Rate prompt
<Decoder><Bit Rate>
or use the DBR command from a terminal.
6.1.4.4 Decoder Algorithm
The decoder algorithm is selected at the Algorithm prompt
<Decoder><More><Algorithm>
or using the DAL command from a terminal. The decoder algorithm
can be different from the encoder algorithm only in the decoder
independent YES mode.

6.1.5 Advanced Encoder and Decoder Configuration
At this point, the encoder and decoder sections of the CDQPrima are
completely configured for normal operation. The next section
discusses advanced features that set the CDQPrima apart from other
codecs. If you will not be using any advanced encoder or decoder
features, you can skip to Section 6.2
The encoder and decoder configurations, either using Quick
Configurations or the manual configuration method, will enable the bidirectional transmission of audio for most applications. The CDQPrima
has many exclusive features that add to the utility and flexibility, and
these are discussed here.

In dual mono, stereo and joint stereo modes, audio input to the left
channel will be encoded as left channel audio, and audio input to the
right channel will be encoded as right channel audio. If mono is
selected, under normal operation, only the audio input to the left
channel is encoded.
The ECS command
<Encoder><More><Audio In><Copy/Swap>
allows you to exchange the left and right audio inputs (stereo modes) or
use the right input for mono. You can even copy one channel into the
other. If you want to use a stereo source for mono transmissions, you
can use any one of three different mono-mix settings available using the
EMM
<Encoder><More><Audio In><Mono Mix>
command. The mono-mix choices are L+ R (M0), L+ R - 3 dB (M3), or

Another MUSICAM USA exclusive feature available on the CDQPrima
is Advanced Concealment of Errors (ACE). ACE is based on CRC
(Cyclic Redundancy Code) protection of the ISO/MPEG Layer II scale
factors.
This feature is controlled by the DSP
<Decoder><More><ACE>
and ESP
<Encoder><More><General><ACE>
commands. In general, it is better to use scale factor protection if the
data channel is noisy (high BER). Scale factor protection (ESP) is used
for all ISO/MPEG Layer II types of bitstreams. Scale factors are the
levels of the digital audio signal within a sub-band. There are 32 subbands and the scale factors change the level over a 120 dB range. An
error on any scale factor will cause a perceptible impairment in the
audio. To prevent this, scale factor protection can be inserted at the
encoder and if the decoder is capable of recognizing it, then the decoder
can perform a concealment operation to repair the damaged scale
factor. If the decoder does not know about scale factor protection, the
audio is decoded and any damaged scale factors cause an impairment.
!note:
Scale factor protection is not bi-directional, and must be enabled
independently for each direction. If ESP has enabled scale factor
protection, the far end decoder must enable scale factor correction
with the DSP command. If only one end has scale factor protection
enabled, audio may be muted. The CDQPrima’s Scale factor protection
is not compatible with other manufacturers codecs. Scale factor
protection is compatible with MUSICAM USAs CDQ2001 and Prima LT
codecs.

required to completely configure the CDQPrima’s encoder and decoder for
operation. Speed dial entries differ from Quick Configurations in that they
also contain ISDN numbers to dial.

Although creating a Quick Configuration or speed dial entry may
sound difficult or confusing, this is really not the case. The following
examples show how easy it is to create table entries.
6.3.2 Example 1 – Save Current Configuration
There may be many instances where a pre-programmed Quick
Configuration may be close to, but not exactly what you need. For
example, there is no Quick Configuration for MPEG layer III at 128
kb/s mono, decoder independent. There may also be instances where
you have created a custom configuration that you would like to save for
future use. Both these scenarios are easy with the CDQPrima’s ability to
save the current configuration. Here’s how:
The closest configuration to 128/48 Layer III, mono, decoder
independent, is Quick Configuration 37, 128/48, Layer II, mono,
decoder independent. To create the wanted configuration, load Quick
Configuration 37, change the encoder and decoder algorithm to MPEGL
Layer III (MPEGL3), and save.

Click on Speed Dial, click on New Entry, enter a name, Save.
In all cases, the CDQPrima will return an ID number. This is the ID
number that is used to load the newly created entry.
In this example, a Quick Configuration entry was created since the
CDQPrima was not connected to another codec. We could just as easily
have created an actual speed dial entry, which would dial into another
codec, if we had dialed into and were connected to the other codec
when we saved the current configuration.
6.3.3 Example 2 – Different Send and Receive Algorithms
In this example, we will create an actual speed dial entry that will be
used to send high quality, MPEG Layer II stereo audio to a recording
studio but receives low quality, low delay G.722 audio from the studio
for cueing purposes.

6.3.4 Example 3 – Using Place Holders
The last example will show how to create a speed dial entry for
broadcasting stereo audio to three different locations. To illustrate the
use of place holders, this example assumes that we will dial the first
location on lines 1 and 4, but the second location will call us on lines 2
and 5 and the third location will call us on lines 3 and 6.
Place holders are used when some, but not all lines are dialed. In this
example, we will be dialing out on lines 1 and 4, but lines 2, 3, 5 and 6
will be receiving calls. We will need to use place holders on lines 2 and
3 since the cdqPrima will dial all numbers in sequence, starting with

Once the parameter has been changed, press the up arrow button to
exit the edit mode.
6.3.7 Example 5 – Changing The Phone Number
Let’s say that your CDQPrima is connected to ISDN through a PBX
system that requires you to dial ‘9’ before making a call. You will need
to change the phone number of the pre-programmed Test Line entries
in order to connect to them. Editing the current entries is easy. Here’s
how:
•
Press the SDSET button, select the <Edit Entry> option, and using the
right arrow button, scroll until we see the desired entry to change,
“CCSTEST64”. Note that we used the right arrow button since the
entries are stored alphabetically, going right requires fewer button
presses.
•
Press ENTER to edit the entry.
•
Continue pressing the right arrow button to scroll through the
settings until the parameter we need to change is displayed. In this
case, when the phone number is displayed, press ENTER.
•
Using the alphanumeric keypad, enter the new phone number. Press
ENTER when done.
