Introduction
One appropriately equipped TEAM system can accommodate
point-to point audio transmission or large-scale network systems.
1. Overview
T
he TEAM audio transmission system is the most flexible system
of its kind. The TEAM system provides point-to-point
transmission of up to 12 audio channels, and can be equipped to
become the central hub of a multi-location audio delivery network. The
TEAM system is designed for operation on both the 1.544 Mb/s North
American standard T1 and the 2.048 Mb/s European standard E1
systems. Additionally, TEAM can connect to smaller capacity
Dedicated Data circuits, or to ISDN lines, through its optional X.21 or
V.35 modules. TEAM can even be used for streaming audio over the
Internet, and the audio can originate virtually anywhere in the world!
With seven available slots and four different plug-in modules, you can
customize your TEAM system for your applications. You can tailor the
audio to your applications with five different audio compression
algorithms and one linear (non-compressed) algorithm. The ability to
send audio to multiple locations, insert and drop audio programs and
establish cross-connections are all standard features of the TEAM
system.
1.1
Basic Features
The TEAM system is housed in a 4U high (7”, 17.8 cm) 19” (48.3 cm)
rack-mountable enclosure. The TEAM is convection cooled, and no
forced air cooling is required. TEAM’s modular design, with internal
power supplies, allows for custom configurations and future upgrade
capability. All modules except the Command Processor are hot
1-1
TEAM U S E R S G U I D E
swappable and thus can be removed and installed without the need to
power-down the system.
Each TEAM system requires the installation of at least one power
supply and one control processor. Two different power supplies are
available: Universal AC (90–250 VAC, 48–65 Hz) and 48/60 volt (42–75
VDC). Two power supplies can be installed to operate in a dualredundant configuration.
A single Control Processor is used to control and monitor all functions
of the TEAM system and all plug-in modules. The Control Processor
allows connections to a terminal or computer through RS232 interfaces.
With two user definable alarms, four optically-isolated inputs and four
relay outputs, you can create local or remote ‘events’ for control of
peripheral equipment. An included Ethernet port for connection to a
Windows®-based media server allows easy streaming if MPEG Layer 3
audio.
1.2
Audio Features
Each encoder and decoder module is capable of two-channel operation.
Up to six encoder or decoder modules can be installed in a TEAM
system yielding up to 12 audio channels.
Analog audio input and output is available with adjustable input
sensitivity and output levels, variable impedance, balanced or
unbalanced. Both AES/EBU and S/PDIF digital audio I/O is available,
with automatic sample rate adaptation and internal, line, or external
synchronization.
Many algorithms are supported to provide audio quality suited to any
application.
Since multiple encoder and decoder modules are
supported, multiple algorithms can be used simultaneously.
Supported algorithms are listed below;
G.722 :
This early PCM-based algorithm yields 7.5 kHz commentary
grade mono audio ideally suited for voice applications, such
as news, sports, etc. With low delay, talk-back is possible
without cumbersome delay compensation schemes. G.722 as
implemented in TEAM supports a bit rate of 64 kb/s.
1-2
TEAM U S E R S G U I D E
CCS MUSICAM® / ISO/MPEG Layer 2: ISO/MPEG Layer 2 (known
as MUSICAM in Europe) is ideally suited for high fidelity
music applications. With bit rates as low as 64 kb/s, MPEG
Layer 2 can deliver moderate fidelity monaural audio with
moderate delay. Full fidelity (20 Hz to 20 kHz) transparent
monaural audio at bit rates of 128 kb/s, and full fidelity
stereo audio at 256 kb/s (20 Hz to 20 kHz) is possible. Using
higher bit rates allows for multiple encode/decode cycles
without audible degradation.
MUSCIAM USA has spent thousands of hours and
conducted dozens of listening tests to fine-tune MPEG Layer
2 to yield even better performance. Fully compatible CCS
MUSICAM enhanced Layer 2 can deliver near-transparent,
full fidelity joint stereo audio using as little as 128 kb/s, and
true stereo at 192 kb/s. CCS MUSICAM enhanced Layer 2
encoding is fully compatible with all Layer 2 decoders and
makes any decoder sound better.
TEAM supports MPEG Layer 2 bit rates from 64 kb/s up to
384 kb/s per channel. The decoder will automatically
determine the sample rate of the incoming audio.
ISO/MPEG Layer 3: Optimized for 64 kb/s per channel, Layer 3
becomes the ideal choice when high fidelity is required but
transmission capacity is limited. Near transparent, full
fidelity, true stereo audio is delivered using as little as 128
kb/s. The disadvantages of Layer 3 are longer delay, poor
cascading, and poor post-processing.
Bit rates from 64 to 320 kb/s are supported. As with Layer 2,
the decoder will automatically determine the sample rate of
the incoming audio.
J.41:
This algorithm can deliver master-quality (contribution
grade) mono audio using 384 kb/s per channel. With only
2:1 compression, very low delay and very high immunity to
cascading and post processing effects is achieved. J.41 is
noted for providing audio indistinguishable from the source
even after many tandem codings. The audio sample rate is
fixed at 32 kHz.
1-3
TEAM U S E R S G U I D E
J.57:
1.3
Sampled at 48 kHz, with minimal audio compression, there is
minimal degradation, even after multiple passes. J.57
requires the full capacity of the E1 link for a stereo program.
Multiplexer Features
TEAM’s powerful multiplexer combines a significant number of
features in a single plug-in module. Each module can connect to one or
two T1 or E1 circuits without changing any hardware configurations.
In addition, multiple TEAM units can be used in a daisy-chain
configuration through the Drop/Insert ports to connect even more
locations or expand the capacity of the TEAM’s main chassis. Operation
is the same, regardless of which interface is used, T1 or E1.
The basic multiplexing functions; i.e., sending and receiving up to 12
channels of audio are enhanced with many features, including
Drop/Insert and cross connect functions. These features can be
combined to make your TEAM system the backbone of a star network
topology.
It is not necessary for all audio channels to use the same bit rate, sample
rate or algorithm.
1.4
Control
Monitoring and control of all functions and settings is through one of
two remote control ports on the front panel of the Control Processor.
Far end remote control is also possible using ancillary data channels. In
addition, a Windows® Remote Control program is available for easy
point-and-click operation of the TEAM system.
1.5
Ancillary Data
When using any MPEG compatible algorithm, each individual
encoder/decoder pair allows one channel of ancillary data to be
multiplexed into the audio bit stream and subsequently demultiplexed.
This RS232 data path supports multiple baud rates and can be used for
many different user applications.
Two additional ancillary data paths are available on the Control
Processor module for use with other algorithms.

1.6 Streaming Audio
It is now possible to use the TEAM, along with a server, to stream
MPEG Layer 3 audio over the Internet. TEAM allows the audio to be
from a local source or from anywhere in the world! Please note that
software revision 1.7.7 or higher is required, and the TEAM must
contain a Control Processor Module equipped with an Ethernet port.

Control Processor
A single microprocessor-based module controls all functions of the
TEAM system.
2. Overview
T
he heart of the TEAM system is the Control Processor. This
MPC860 Power-PC communications controller-based module
handles all maintenance, alarm and control functions for the
TEAM system and all installed modules. In addition to these basic
functions, the Control Processor also provides two bi-directional
ancillary data ports, and a 10/100 Ethernet port that allows streaming
audio through a Windows®-based Media Server.

Control Processor
The Control Processor functions are organized into three functional
groups: System Administration (SA), supporting initialization,
configuration, event notification, statistics gathering and software
installation. System Operation (SO) supports features associated with
Management and Control (M&C), including backplane and data
interface administration. The System Maintenance (SM) function
supports troubleshooting.
2.1 Control Processor Installation
The Control Processor must be installed in the left-most slot of the
TEAM system. Unlike all other TEAM modules, the Control Processor
is not hot swappable. Power must be removed before removing or
installing a Control Processor module.
2.2 Front Panel Connectors
All control, monitoring, and alarm functions for the TEAM system are
accessed from the front panel of the Control Processor module.

2.2.1
Remote Control Command Structure
The structure of all remote control commands is a three-letter command
followed by parameters.
Not all commands have associated
parameters, but if they do, parameters are separated from each other by
a space.
All commands fall into one of six categories, with the initial letter of the
command defining the category. All commands common to the full
TEAM system begin with the letter ‘C’. Encoder and Decoder
commands begin with the letter ‘E’ and ‘D’, respectively. Network
commands begin with an ‘N’, and maintenance commands begin with
an ‘M’
On-line help is always available by typing
nQQ
Where n = the command category, C, E, D, N, or M. This returns a list
of all commands within the category. Then, type
HELP cmd
For the command summary and syntax.
2.2.2
RS232C Maintenance and Control Port
The remote control port PC1 (CONFIG) is on the front of the Control
Processor module. An RS-232C port allows the connection of a PC or
terminal and is used to control all functions of the TEAM system. This
port, configured as a DCE device, allows the connection of a standard
VT-100 style monitor or emulator. This connector is wired to allow a
straight-through cable to be used between the PC or monitor and the
TEAM system as shown in the following table:

The RS232C port supports rates of 1200, 2400, 4800, 9600 or 38,400 baud,
no parity, 8 data bits, 1 stop bit. The baud rate is selected using the CRB
command:
CRB rate

The factory default baud rate is 38,400. When configuring the RS232C
port for the first time, you must have your terminal set for the factory
default settings.
If a terminal or emulator does not support full duplex, you can set the
Command Echo to ‘ON’ using the CRE command:

2.2.3
Ancillary Data Ports
= ON or OFF
The two 25-pin RS232 ancillary data ports on the Control Processor are
wired as DCE devices as shown in Table 2-2. Flow control is not
supported on either port. These uni-directional ports provide ancillary
data paths that are in addition to, and independent from, the ancillary
data paths of the T1/E1 module. Rather, these ports can be considered
as supplements to the data ports on the Encoder or Decoder modules.
Since each port can be connected (mapped) to an Encoder or Decoder
module, only one direction of data is supported.
The ancillary data ports allow locally connected devices to
communicate with remote devices via included data bits within the
audio bitstreams. The Command Processor provides the interface
between these two ports and the Encoder or Decoder plug-in modules.

Table 2-2 — RS-232 Ancillary Data Port Pin Connections
Data rates for the ancillary data ports on the Command Processor can
range from 1200 to 38,400 baud and are selected using the CDR
command:
CDR port baud
port = A or B
baud = 1200, 2400, 4800,
9600, 19200 or 38400
When setting the speed of the ancillary data port on the Command
Processor, you must also set the speed of the linked Encoder or
Decoder data using the EDR or DDR commands. This step is necessary
since the EDR and DDR commands not only set the speed of the encoder
or decoder data port, but also set the speed of the data itself.
The uni-directional link, or path, between a CP data port and Encoder
or Decoder module is selected using the CAP command:
2-4
TEAM U S E R S G U I D E
CAP srcport destport

destport
= Source slot/port,
slot = 0,…,7, (0 = CP)
port = A or B
= Source slot/port,
slot = 0,…,7, (0 = CP)
port = A or B
When configuring the Encoder or Decoder module using the CAP
command, the internal port (looking towards the CP) is ‘Port A’ and the
local port is ‘Port B’.
Bi-directional Ancillary Data can be achieved if each TEAM system is
equipped as a codec (both Encoder and Decoder modules) with the
transmit and receive Ancillary Data signals routed to allow bidirectional communications.
As an example, data from a local PC needs to be sent to another
computer at the far-end site, as pictured in Figure 2-2:

In this example, a computer in City ‘B’ is sending data to another
computer in City ‘A’. The computer is City ‘B’ is connected to the
Encoder module in Slot 2 of the TEAM system. The CAP command is
used to set up this configuration:
CAP 2B 2A
This sets up the Encoder Module in slot 2 to receive Ancillary Data from
its local port.
In City ‘A’, Ancillary Data from the Decoder in slot 3 is routed to Port A
on the CP module with the command:
CAP 3A 0A
The CRP command is used to remove a uni-directional connection
between the specified Data Port and the specified Encoder or Decoder
module:

The CP supports three modes of Ancillary Data, BYPASS, NOMUX and
OFF. In the BYPASS mode, the CP ancillary data ports are connected
directly to the Encoder or Decoder without any processing delay. In the
NOMUX mode, the ancillary data is processed by the CP before being
routed to or from the Encoder or Decoder.

Alarm / Relay Port
The TEAM’s alarm/relay port is designed to provide both alarm and
external control capabilities.
Six alarm relays are provided; Alarm A, Alarm B, RL0 through RL3, the
functions of which may be user defined. The A and B alarms contain
both normally open and normally closed contacts. RL0 through RL3 are
dry-contact type relays. The status of the A and B alarms can also be
monitored via two front panel LEDs.
The Control Processor contains four optically isolated inputs. These
user programmable inputs allow the user to input control signals that
are monitored by the CP. The CP software detects when these inputs
2-7
TEAM U S E R S G U I D E
change state, and this information can be used locally or sent to the farend unit.
Four sets of SPST dry contact relay outputs are also provided. These
outputs are intended to control external devices and signal status
conditions of the TEAM. The CP controls the state of these relays based
on various system events, discussed in section 2.5.1. Further, these
relays can be toggled using the XRL command:

A multi-speed LAN connection is provided on the Control Processor’s
front panel. Capable of direct connections to Local Area Networks, this
port is used for streaming MPEG Layer 3 audio to the Internet through
a 9 10.
2.3 System Administration
The Control Processor’s System Administration functions include
system initialization, configuration, event/alarm notification, statistics
gathering and software installation.
2.3.1
System Initialization
When the TEAM is first powered up it executes a boot sequence.
During the boot sequence, the system status will be reported as well as
any modules that have been found. The time stamped status includes
module type (encoder, decoder, T1/E1 multiplexer, and X.21), the slot
number in which the module is installed, and the hardware revision
level of the module.
At first, the system initialization process generates the event:
STATUS:System Initializing, Software Version:1.6.3
and also displays the software revision. Next, the system begins the
process of auto-detecting all plug-in modules. Each time one of the
2-9
TEAM U S E R S G U I D E
seven slots are polled, the system will report the status of that slot, an
example shown here:
STATUS:ENCODER Card Detected - Slot:3, Class:0,Rev:0
and includes the slot, card type and hardware revision. If no module is
detected, the system will report
STATUS:Slot 2: Unknown card type
with the slot number. If no module is detected in a slot previously
occupied, the system will report:
STATUS: Card Missing
Once all modules have been detected, the sequence continues when the
CP loads the software and configuration information each module
requires, and initializes each module. Status is reported for each step:
STATUS:Downloading ENC_TDM Slot 3
STATUS:Loading DSPE micro boot code Slot 3
STATUS:DSP Download DSPE micro boot code complete Slot 3
The boot cycle is complete when the system responds:

Each step of the boot cycle is recorded in a System Log, which contains
time-stamped STATUS and ERROR events for all detection,
initialization and software loading steps. The system log can be viewed
by using the XLG command:
XLG event
event = 0 (clear log), 1…100
Up to 100 lines can be displayed, starting from the top of the log. The
first line is the most recent event; the last line is the oldest entry. All
entries are time stamped relative to system power-up.
To list the current status of all detected modules, use the CST command,
which returns the status and class of all plug-in slots. An example of

2.3.2
System Configuration
The CP maintains a non-volatile database for the entire TEAM system,
maintaining a unique configuration for each of the seven slots in the
mainframe chassis.
The CP will update the stored configuration parameters when a remote
control command that alters parameters is entered. The CP also
periodically scans the system to determine if any modules were
removed or added. A new module will generate a
STATUS: Card Detected
message, that indicates what type and revision of the module and the
slot that it is in, while a missing or removed module will generate an
ERROR: Card Missing
message, with the slot number type and revision of the module that was
removed. In addition, if a module has been removed, any active
connections to that module are disconnected.
For each module, the CP loads a stored configuration table from nonvolatile RAM. If the stored configuration is valid, the system responds:
STATUS: Configuration Database Loaded
If the configuration is not valid, the system will report:
ERROR: Configuration Database Checksum Failed
– System Configuration Reset
and load a factory default configuration.
Next, the CP compares the software that was previously booted to the
current version, and if the revision numbers differ, the CP resets the
Configuration Database to the system default and reports an error:
ERROR: Current CPSYS version mismatch
– System Configuration Reset
Each TEAM module requires several software ‘things’ to be
downloaded for proper operation. The CP will report
STATUS: Card Downloaded
after each ‘thing’ is loaded, and
STATUS: Card Configuration
as each card configuration is updated. If an error is encountered, the CP
generates an error message detailing which ‘thing’ failed to load.
2-12
TEAM U S E R S G U I D E
Once the CP is done downloading/configuring all plug-in modules, the
system initialization process is complete.
During normal operation, each remote control command that alters a
configuration parameter forces an update of the Configuration Database
and checksum stored in RAM. The non-volatile memory is updated
automatically as some parameters are changed, while others are
updated periodically. The MSY command causes an immediate update
of non-volatile RAM with the current configuration parameter values:
MSY
The CP periodically auto-detects plug-in modules to determine if
modules have been removed or added. If a new module is detected, the
CP generates a
STATUS: Card Detected
message, and downloads/configures the card as necessary. If a module
is removed, the CP generates a
STATUS: Card Missing
message.
The CP does not alter the stored Configuration Database when a
module is removed. If a module is removed and a module of the same
type is re-installed in the same slot, the new module will inherit the
previous configuration. If a different type of module is installed, a
factory default configuration will be loaded.
Use the XPO command to set the slot poll/detection timer:

ConfigUpdate (2)
= 0 (disables), 1…254

Please refer to the appropriate chapters for the default settings of all
other plug-in modules.
2.4 Backplane
All plug-in modules fall into two classes: Network modules and Local
modules. Currently TEAM can support only one Network module.
Only the number of available slots not used by Network modules limits
the number of Local modules. The T1/E1 modules have two ports, a
Networl port (N) and a Drop/Insert port (D/I). The X.21/V.35 module
also has two ports, A and B, whereas all other modules have only one
port, port A. The Command Processor has an Ethernet port, Port A.
Module classifications and ports are shown here:

Table 2-7 — Module Class
The TEAM backplane has 16 Channels, each supporting up to thirty-two
64 kb/s Timeslots for E1 (two E1 time slots are reserved, leaving only 30
for user information), or 24 for T1. These timeslots are used to connect
Local and Network modules. A collection of timeslots used to make a
connection is referred to as a Subchannel. Data is Dropped into the
backplane timeslots (Subchannel) by Source modules and Lifted from the
backplane by Destination modules.
Each installed Network module must have a unique address, or Network
Card number, ranging from 1 to 4. Mapping between the Network
modules and the backplane Channels is fixed, as shown below.
The Control Processor manages Subchannel IDs transparently and
broadcasts the Subchannel IDs across the Backplane Channels to notify
modules when to Drop or Lift data to or from timeslots. The CP assigns
Subchannel IDs 1—14 to connections as they are established.
Subchannel ID 15 is broadcast by the CP to the other modules to
indicate an unassigned timeslot. Subchannel ID 0 is set in the modules
2-15
TEAM U S E R S G U I D E
when they have no Subchannel Connection assigned for a given
direction. The maximum number of subchannel connections is 14 in the
send direction (relative to the E1 card) and 13 in the receive direction,
for a total of up to 27 subchannels.
When a subchannel is set up, a Channel Group and Bit Rate (Nx64, N = 130 for E1, 1-24 for T1) are specified that define the group of timeslots in
the Channel that are connected. The Control Processor supports the
Channel Group timeslot assignment defined as shown in Table 2–8A for
E1 and 2-8B for T1:
Please note that International convention has numbered E1 Timeslots
from 0 to 31. For E1 (0 and 16 are reserved):

Table 2-8B — Timeslot Assignment for T1
As an example, consider a TEAM system equipped with a T1
multiplexer and four Encoder modules. We want to send two channels
of G.722 audio at 64 kb/s each, one stereo MPEG Layer 2 program at
128 kb/s, and two stereo programs at 256 kb/s each.
There are several solutions to this requirement, one being Channel
Groups 1 and 2 for the G.722 programs. This uses Timeslots 1 and 2.
Selecting Channel Group 2 for the 128 kb/s program uses Timeslots 3
and 4. For the 256 kb/s programs we again select Channel Group 2,
using Timeslots 5, 6, 7 and 8, and Channel Group 3, using Timeslots 9,
10, 11 and 12. Note that although we assigned Channel Group 2 more
than once (three times, to be exact), we have not assigned the same
timeslots more than once, which would be an error.
2.4.1
Network Module Number Assignment
A single Network Module can be installed, and requires a unique
“address” number. This number maps the module to the backplane
channels as described previously. The NNC command tells the CP to
establish new backplane connections on all 30 (or 24 for T1) Drop/Lift
timeslots based on the Network Module number.
More than one network module can be installed in a TEAM card cage,
the E1 or T1 module, and each is assigned an ID number. Since the
TEAM recognizes which module is installed, all commands that return
a system or module status will identify the installed module.
The CP first checks to see if the selected number (address) is not in use,
and if not, the new Subchannel Connection is allocated, overriding any
previous connections. If the selected number is already in use, an error
condition is reported.
Note: when a Network Module is assigned a new Network Module
number, all Local modules formerly connected to that Network
module must be reconnected. The user must either: 1) remove existing
2-23
TEAM U S E R S G U I D E
Subchannel Connections to this Network Module (using the NRC
command) and set up new Subchannel Connections to this or another
Network Module, or 2) assign the old Network Card number to a
different Network Card. In this case, the Network Card will inherit the
connections formerly associated with the other Network Card.
2-24
TEAM U S E R S G U I D E
2.4.2
2.4.2 Network Module / Local Module Subchannel Connections
The NMC command:
NMC src/port dest/port rate changrp
= source slot/port:
slot = 1,…,7
port = A, B, N, or D
dest/port = destination slot/port:
slot = 0,…,7 (0 = CP)
port = A, B, N, or D
= bitrate:
rate
N x 64, N = 1,…,30
= channel group, 0,…,74 (E1)
changrp
1,…,56 (T1)
Src/port
controls the setup of connections (Subchannels) between a Network
module and a Local module. The CP supports up to 14 simultaneous
Subchannel connections.
When using the TEAMs streaming audio capabilities, the Command
Processor must be set as the destination (Slot 0, Port A). Currently,
streaming audio only supports 128 kb/s (N = 2).
As an example, suppose there is an encoder card in slot 3, an E1
multiplexer card in slot 5 and a decoder card in slot 7. I want to
configure for 384 kb/s send and receive using Channel Group 2. The
following commands will do this:
NMC 3A 5N 6 2
NMC 5N 7A 6 2
The CP checks if the selected cards/ports are present, and the specified
Bit Rate and Channel Group is available, and no connection already
exists in the specified direction. If so, a Subchannel ID is set up along
with the Slot RAM so that the module can Drop/Lift data to/from the
appropriate timeslots on the backplane. If all of the above conditions
are not met, an error condition is reported.
A module Port can support a single Subchannel connection in each
direction (Drop/Lift). Once a Subchannel is assigned to a Port for a
2-25
TEAM U S E R S G U I D E
given direction, that connection must be disconnected before setting up
a different connection. However, Decoder modules support a “multiple
listen” feature, this means that multiple decoders can receive the same
E1/T1 channel group. Thus, if the configured Bit Rate/Channel Group
is already in use, the specified decoder module is added to the existing
Subchannel Connection.
The NRC command:
NRC src/port dest/port
= source slot/port:
slot = 1,…,7
port = A, B, N, or D
dest/port = destination slot/port:
slot = 0,…,7 (0 = CP)
port = A, B, N, or D
src/port
controls the removal of connections (Subchannels) between a Network
module and a Local module. The CP disconnects all timeslots
associated with the Subchannel and frees up the assigned Subchannel
ID.
2.4.3
Subchannel Connection Initialization
During the Control Processor boot cycle, or when a Network Card is
detected, the Control Processor initializes the Subchannel Connections
as follows:
T1/E1 Multiplexer Module — If there is no T1/E1 module currently
installed, the CP allocates a Subchannel ID, sets up the CP Slot
RAM and assigns up to 32 Drop & Lift timeslots to Backplane
Channels.
If the current Network Card number is already in use, the CP
logs the message:
ERROR: Connection Failure – Network Card
Number unavailable, Slot # Port #.
and the card does not initialize. Otherwise, the CP sets the card
state to READY.
When the Control Processor detects a Local Card, either during system
boot or when a module is installed, the CP initializes the Subchannel
Connections as follows:
2-26
TEAM U S E R S G U I D E
Encoder module — For all encoder modules that have a Drop/Lift
Subchannel ID configured, the CP checks to see if the configured
Network Card is present and the configured Bit Rate/Channel
Group is available. If available, a Subchannel ID is allocated, and
the Slot RAM and the T1/E1 modules XPOINT are set up so that
the appropriate timeslots can be Dropped or Lifted from the
backplane.
If the set up of the Subchannel Connection fails, the CP logs the
message:
ERROR: Connection Failure – Network Card or
Timeslots unavailable, Slot # Port #.
and the card does not initialize. Otherwise, the CP sets the card
state to READY.
Decoder module — For all decoder modules that have a Drop/Lift
Subchannel ID configured, the CP checks to see if the configured
Network Card is present and the configured Bit Rate/Channel
Group is available. If available, a Subchannel ID is allocated, and
the Slot RAM and the T1/E1 modules XPOINT are set up so that
the appropriate timeslots can be Lifted or Dropped from the
backplane.
If the setup of the Subchannel Connection fails, the CP logs the
message:
ERROR: Connection Failure – Network Card or
Timeslots unavailable, Slot # Port #.
and the card does not initialize. Otherwise, the CP sets the card
state to READY.
A “multiple listen” feature allows multiple decoder modules to
use a Channel Group/Bit Rate already in use. Any decoder
module can simply be added to the existing Subchannel
Connection.
X.21/V.35 module — If a Drop or Lift Subchannel ID is configured (for
each port), the CP checks to see if the configured Network Cards
are present and the selected Bit Rate/Channel Groups are
available (for each port). If available, a Subchannel ID is allocated
(per port) and Slot RAM is set up so that each X.21/V.35 port
2-27
TEAM U S E R S G U I D E
Drops and Lifts the appropriate timeslots from the Backplane (in
a full duplex manner if required). In addition, the T1/E1
module’s XPOINT is set up so that the appropriate timeslots are
received from the T1/E1 Network Port and Dropped onto the
Backplane, and Lifted from the Backplane and sent to the T1/E1
Network port.
If the setup of the Subchannel Connection fails, the CP logs the
message:
ERROR: Connection Failure – Network Card or
Timeslots unavailable, Slot # Port #.
and the card does not initialize. Otherwise, the CP sets the card
state to READY.
2.4.4
T1/E1 Drop/Insert Port Connections
A collection of timeslots that make up a connection between the T1/E1
Network Port and the T1/E1 Drop/Insert Port is called a Drop/Insert
Connection.
One 1.5 Mbit/s (T1) or 2Mbit/s (E1) Drop/Insert
connection is supported in each direction, and the CP manages
Drop/Insert connections transparently. The CP assigns a Drop/Insert
Connection ID when a connection is established for a given direction,
and frees up the ID when the connection is removed. The maximum
number of connections that can be established between the Drop/Insert
Port and the T1/E1 Network Port is 8 per direction (16 total).
The Drop/Insert Port supports the “multiple listen” feature. Thus, if a
decoder card already uses the configured Channel Group/Bit Rate (in
the RECEIVE direction from the Network), the Drop/Insert port is
connected to the timeslots. However, the Drop/Insert port cannot
transmit to the Network on a Channel group/Bit Rate already in use.
The NMD command controls the setup of the Drop/Insert Connections
between the T1/E1 Network Port and the Drop/Insert Port.

2.5 Status Monitoring
There are three status LEDs on the Control Processor module. The
green ‘CPU’ LED illuminates when the Control Processor is powered on
and is ready to accept commands. The two alarm LEDs, Alarm A and
Alarm B, are user definable and operate in conjunction to the two alarm
relays discussed in Section 2.2.4. In addition to the two alarm
LEDs/relays, four other relay actions can be mapped into user-defined
events.
2.5.1
Event-To-Action Mapping
Many specific system events can be mapped into actions, including LED
illumination and relay closures. There are 4 event categories: Common,
Encoder, Decoder and Network events. In addition to the event-toaction mapping available, all events are time-stamped and logged to the
CP system event log. The CP supports the following actions:

A
Activate LED A and Relay A
B
Activate LED B and Relay B
RL0,…,RL3 Activate Relay 0,…,3
CS0,…,CS3 Command Sequence 0,…,3
Table 2-11 System Actions
In addition, each action supports a “+” modifier which latches the
action when an event occurs. The action must then be cleared
manually. Without the “+” modifier, the action follows the trigger,
clearing when the triggering event clears.
The CP also supports seven generic Slot Alarm events, one per system
slot (C10 – C17). This enables you to assign specific Encoder, Decoder
or Network events to a slot alarm, thus enabling you to determine
which installed encoder, decoder or network card is in failure mode if
more than one is installed. The CES command turns ON or OFF Slot
Alarm reporting for the specified event.
Example:
CES D01 ON
If a Decoder card in slot 3 is missing, the CP will generate a Decoder
Event “D01 Decoder Missing” and the Common Event “C12 Slot
Alarm 3”, thus indicating that the Decoder module in slot 3 has been
removed. The CP will execute the actions associated with both events
D01 and C12.
The following event-to-action mapping can be performed using the CEA

Table 2-9 — Event-to-Action Mapping
As an example of using the CEA command to define an event to action,
the command:
CEA N01 +B
assigns the Loss of Sync event (N01) to latch relay B. Remember that
the factory default will activate, but not latch, relay B.
The CP also supports seven generic Slot Alarm events, one per system
slot (C10 – C17). This enables you to assign specific Encoder, Decoder
or Network events to a slot alarm, thus enabling you to determine
which installed encoder, decoder or network card is in failure mode if
more than one is installed. The CES command turns ON or OFF Slot
Alarm reporting for the specified event.
Example:
CES D01 ON
If a Decoder card in slot 3 is missing, the CP will generate a Decoder
Event “D01 Decoder Missing” and the Common Event “C12 Slot
Alarm 3”, thus indicating that the Decoder module in slot 3 has been
removed. The CP will execute the actions associated with both events
D01 and C12.
Events are evaluated and actions are executed based on the poll timers
for each category. The CCE command deactivates all currently activated
events, and can also be used to display current event mapping.
2.5.2
Command Sequences
Utilizing the Event to Action Mapping feature of the TEAM, it is
possible to perform a list of commands upon a certain event. Maybe you
would want the TEAM to change to a backup Network Module when
the primary network link fails. With the TEAM’s command sequences,
2-32

the TEAM can perform this function. Use the CEC Command to enter a
Command Sequence.
The CEC command:
CEC
CEC sn

= Edits the command sequence sn
The CEC command has two functions, either to create a Command
Sequence, or to create a “Quick Card Configuration”. A Quick Card
Configuration is basically a blueprint for a given card’s settings.
A Quick Card Configuration can also be created automatically based on
a card’s current settings. This is done using the CSE Command.

System Statistics
All other system status monitoring, including the status of all installed
modules, is performed through either of the two remote control ports,
and requires a terminal or emulator.
Slot status, the type of module, state, revision, class, and version can be
displayed using the CST command discussed previously. There are
several different information formats returned by this command. If no
slot number is specified, then this command returns the slot status. If a
slot number is specified, than a detailed status report for that slot is
given, for example:

T
he TEAM encoder module is a standard stereo audio encoder,
with a choice of analog and/or digital (AES/EBU or S/PDIF)
audio inputs and an RS232C ancillary data channel. Numerous
algorithms and bit rates are supported, including 64 kb/s G.722, Nx64
kb/s MUSICAM-enhanced Layer 2 and MPEG Layer 3, J.41 (384 kb/s
mono), and J.57 (J.57 is not currently supported with T1). If multiple
encoder modules are used, different compression algorithms and bit
rates can be used for different channels simultaneously.
The encoder’s powerful 24-bit A/D converter insures low distortion
and high signal-to-noise ratios, regardless of algorithm used. Multiple
sampling rates and input levels accommodate a wide range of audio
sources and bandwidths. With six installed encoder modules, it is
possible to send up to twelve individual, high-fidelity monaural
channels. In addition, different configurations can be used for different
audio channels simultaneously.
3.1 Encoder Installation
Your TEAM system can support up to six encoder or decoder modules.
Modules can be inserted in any of the seven free slots (at least one
Network Interface module is required), except the two right-most
power supply and the left-most control processor slots. It is not
necessary to remove system power when removing or inserting encoder
modules. The installation or removal of an encoder card is
automatically detected.

3.2
MPEG Algorithm Modes
3.2.1
Full Stereo and Dual Mono
Users have expressed confusion concerning the differences between full
stereo, dual mono and joint stereo algorithm modes. 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.
We should note that the original reason for the “Full Stereo” and “Dual
Mono” distinction is a throwback to consumer equipment. For
example, in MTS television audio, Full Stereo refers to stereo program
audio, whereas Dual Mono refers to monaural audio with a secondary
audio program (SAP).
3.2.2
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 assigned on a frame-by-frame
basis. This dynamic bit allocation results in wider bandwidths and
higher signal-to-noise ratios than are possible with the fixed bit
allocation of the other modes. If the bit allocation logic 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 and low frequencies. The
infinite left-right sound stage is blended into seven locations at high and
low frequencies should the bit allocation logic deem it necessary.
However, it has been shown that any spatial blending is in frequency
bands where the human auditory system would normally blend stereo
signals.
After rigorous testing with trained listeners, joint stereo audio has been
determined to yield higher perceived audio quality than stereo or dual
mono at bit rates of 256 kb/s or lower.

Please note that the encoder algorithm mode has meaning only for
MPEG algorithms and is ignored for G.722, J.41 and J.57.
3.3 Encoder Algorithms
The TEAM encoder module currently supports seven different
algorithms that enable you to meet any audio quality requirement, from
voice only to digital mastering quality. In addition, there is additional
on-board memory for new algorithms to be installed as they are
developed.
3.3.1
G.722
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, commentary grade audio over a
single 64 kb/s channel. Please note that the TEAM system is full duplex
only if equipped with both encoder and decoder modules.
The key advantages of G.722 are its compatibility with most other
codecs and very low coding delay times. G.722 is ideal for situations
where instantaneous talkback is required, such as dial-in talk shows,
two-way IFB and distant interviews. The main disadvantages are it’s
limited audio fidelity, poor signal-to-noise ratio, and poor cascading
properties. G.722 is not recommended for music applications.
With sampling fixed at 16 kHz, G.722 can deliver monaural, 7.5 kHz
audio over one 64 kb/s channel. Up to 12 single direction or six bidirectional channels can be supported in an appropriately equipped
TEAM system.
3.3.2
MUSICAM and ISO/MPEG Layer II
MUSICAM® is MUSICAM USA’s enhancement to the ISO MPEG Layer
II encoding algorithm. A psychoacoustic masking-based algorithm,
MUSICAM offers the best possible combination of fidelity, low to
moderate delay and excellent cascading ability at all bit rates.
MUSICAM encoding is fully compatible with all MPEG Layer II
decoders, and since the enhancements are only in the encoder, any
decoder will sound better when connected to a TEAM encoder. Please
3-3
TEAM U S E R S G U I D E
note that the coding delay will vary from 60 to 400 ms, depending on
the sample rate and decoder manufacturer. MUSICAM, as implemented
in the TEAM encoder, supports sampling rates of 24, 32 and 48 kHz, and
bit rates of 64, 128, 192, 256, 320 and 384 kb/s. Up to 12 unidirectional
or 6 bi-directional audio channels can be supported in an appropriately
configured TEAM system.
MUSICAM enhanced MPEG Layer II can deliver 10.2 kHz monaural
audio on one 64 kb/s channel with 24 kHz sampling. Although a
narrower audio bandwidth at 64 kb/s than MPEG Layer III, the
advantages are better signal-to-noise ratio, lower delay, less noticeable
artifacts and better results when cascading and post-processing.
When using 128 kb/s, the TEAM delivers transparent 20 kHz monaural,
near-transparent joint stereo, or 10.2 kHz dual mono (stereo) audio. At
bit rates higher than 128 kb/s, the TEAM delivers transparent joint
stereo or stereo with immunity to degradation even after up to 15
cascades (at 384 kb/s).
Please note that the CCSO and CCSN algorithm designations are both
MUSICAM-enhanced Layer II algorithms. These are included for
connecting to very early CCS Audio Products and MUSICAM USA
decoders manufactured before MPEG Layer II transmission protocol
was standardized.
3.3.3
ISO/MPEG Layer III
Psychoacoustic masking-based ISO/MPEG Layer III can deliver full
duplex, 15 kHz monaural audio using only one 64 kb/s channel. When
using 128 kb/s, transparent 20 kHz monaural audio is possible, with
near-transparent 20 kHz joint-stereo. In dual mono or stereo modes,
near-transparent 15 kHz audio is obtained with bit rates as low as 128
kb/s.
Although at low bit rates, Layer III offers a wider bandwidth than other
algorithms, this additional bandwidth does come at a price. The
disadvantages of using Layer III are the long coding delay times,
typically 300 to 600 ms (depending on sample rate), and poor cascading
ability. In addition, audible artifacts may be noticeable when using
Layer III at lower bit rates, and post-processing, especially digital post
processing, may further degrade the audio.
3-4
TEAM U S E R S G U I D E
At 128 kb/s, the only advantage to using Layer III over MUSICAM is
that Layer III can deliver true stereo with 15 kHz bandwidth. Other
than that, at 128 kb/s data rates, we recommend using Layer III only
when communication with a Layer III-only decoder is required or when
using TEAMs streaming audio capabilities. Even at 128 kb/s, digital
artifacts may be noticeable, and the delay, cascading and postprocessing limitations are still present.
At bit rates higher than 128 kb/s, there is no advantage to using Layer
III over MUSICAM. Layer III bit rates up to 320 kb/s are included only
for compatibility. Your TEAM encoder supports Layer III bit rates of 64,
128, 192, 256 and 320 kb/s, and sample rates of 24, 32 and 48 kHz. Up to
12 one way or six bi-directional audio channels can be supported in an
appropriately configured TEAM system.
3.3.4
J.41
The industry standard J.41 algorithm produces transparent, digital
mastering quality 15 kHz monaural audio using a single 384 kb/s
channel. This non-psychoacoustic-based algorithm, with compression
ratios as low as 2:1, is noted for very low delay, excellent transparency,
and immunity to digital post-processing and cascading effects.
Sampling rate is fixed at 32 kHz, and the bit rate is fixed at 384 kb/s per
channel. Each encoder module can be used to send two monaural
channels (one stereo program). Pre-emphasis is available and is
activated using the EEP command:
3.3.5
J.57
EEP slot emph
slot
= 1,…,7
emph
= NO or J.17
Unlike the MPEG based algorithms available in the TEAM system, J.57
does not depend on redundancy reduction, but rather on companding
(compression / expansion) and multiplexing. This results in minimal
data loss and allows conversion to a format suitable for transmission
directly over E1. Since very little compression is employed, there is no
lost audio and the audio data is theoretically capable of unlimited
encoding cycles without degradation. Since the audio is nearly
uncompressed, one stereo signal uses the full capacity of an E1. J.57 is
an ITU-T standard intended expressly for sending audio over E1, and as
such, is not supported for T1 TEAM systems.
3-5
TEAM U S E R S G U I D E
3.4 Encoder Configuration
If an encoder module is installed in a previously unpopulated slot, or a
slot that previously held another type of module, a factory default
encoder configuration is automatically loaded. If an encoder module is
installed in a slot previously used by an encoder card, the previous
configuration is loaded.
3.4.1
Algorithm Selection
The encoder algorithm mode is selected using the EAL command:
EAL slot algo
slot
= 1,…,7
algo
= G.722, MPEGL2,
MPEGL3, J.41 or
J.57
Please note that when J.41 is selected, the encoder sample rate must
be set at 48 kHz. Although the J.41 standard defines the sample rate
at 32 kHz, the signal is internally re-sampled and filtered.
Factory default = MPEGL2.
3.4.2
Encoder Line Format
Two line formats are available, Single Line and Independent Mono.
Independent Mono is used only with monaural-only algorithms J.41
and G.722 when stereo or independent mono operation is desired, for
example, stereo J.41 (dual mono). Independent Mono line mode insures
that both monaural channels have uniform delay.uu
All other algorithms and modes should use the single-line format. The
ELI command is used to set the encoder line format:
ELI slot line
slot
= 1,…,7
line
= S or I
Factory default = Single Line.
3.4.3
Encoder Bit Rate
MPEG algorithms allow a wide selection of bit rates enabling you to
adjust the transmission bit rate to your application. The NMC command
is used to select the number of subchannels used, thus determining the
bit rate. Refer to Section 7.5.3 for information on the NMC command.
3-6
TEAM U S E R S G U I D E
Bit rate selection is valid only when using any of the MPEG-based
algorithms. When using non-MPEG algorithms, the bit rate is set by the
algorithm specifications.
Factory default = 384 kb/s.
3.4.4
Encoder Sample Rate
When using any MPEG algorithm, the sample rate (in kilohertz) can be
selected using the ESR command:
ESR slot rate
slot
= 1,…,7
rate
= 16, 24, 32 or 48
For non-MPEG algorithms, the sample rate is fixed and determined by
the algorithm specifications. The sample rate for G.722 is fixed at 16
kHz. J.41 and J.57 use 48 kHz sampling.
Please note that due to the maximum 1.99:1 ratio of the rate converters,
certain encoder sample rates are not valid when using digital audio
inputs.
Audio sample rate
Valid encoder sample rates
32 kHz
24, 32 48 kHz
44.1 kHz
24, 32 48 kHz
48 kHz
32, 48 kHz
Table 3-1 – Audio sample rate vs. Encoder sample rate
Please do not confuse the digital audio sample rate with the encoder
sample rate.
Factory default = 48 kHz for MPEG algorithms, J.41 and J.57; 16 kHz for
G.722.
3.4.5
Channel Swap and Mono Mix-down
It may sometimes be necessary to exchange left and right channel audio.
For example, when in a monaural mode, only the audio input to the left
channel is encoded. Using the channel swap feature allows right
channel audio to be encoded. You can therefore switch audio sources at
any time. This is accomplished using the ECS command:
ECS slot mode
slot
= 1,…,7
mode
= NORMAL or SWAP
3-7
TEAM U S E R S G U I D E
Mono mix-down allows you to mix the left and right channel signals to
monaural for encoding. It is not necessary to use external audio mixing
to mix a stereo program to mono. There are three mix-down modes
available, L+R (M0), L+R – 3 dB (M3) and L+R – 6 dB (M6). Mono mix
has no effect when any stereo encoding mode is selected.
EMM slot mode
slot
= 1,…,7
mode
= OFF, M0, M3 or M6
Factory default, channel swap = NORMAL.
Factory default, mono mix = OFF.
3.4.6
Ancillary Data
In addition to the ancillary data ports on the CP module, each encoder
card has one ancillary data port that can be used to send RS-232 data to
a far-end decoder when using any MPEG algorithm. This DB25
connector allows RS-232 data to be sent directly to the encoder DSP and
combined with the MPEG audio data. The far-end decoder then
separates the ancillary data from the audio data. A true three-wire data
path is provided; flow control is not provided. Data rates from 300 to
38,400 bits/sec are supported and selected with the EDR command:
EDR slot rate
slot
= 1,…,7
rate
= 1200, 2400, 4800,
9600, 19200 or
38400
Also note that when present, ancillary data uses bits normally assigned
to audio data. Under most circumstances, this will not noticeably
degrade the audio performance; however, the use of high data rates
with low transmission bit rates should be avoided.
In addition to the connector on the encoder, TEAM allows you to
encode ancillary data from the ancillary data connector on the
Command Processor module. This requires setting the ancillary data
rate on the CP port using the CDR command as well as setting the
encoder ancillary data rate.
MPEG algorithms support several ancillary data formats for
compatibility with other codecs and satellite systems. CCS Standard
(CSTD) can be used to send or receive ancillary data from any CCS
Audio Products or MUSICAM USA codec; CCS Generic (CGEN) can be
3-8
TEAM U S E R S G U I D E
used only with MUSICAM USA’s CDQPrima, Prima LT, RoadRunner,
Superlink or TEAM codecs. The IRTDAB format supports features used
with DAB systems, and ADR is a special case of the DAB format.
Use the EAF command to select the appropriate format:
EAF slot format
slot
= 1,…,7
format = CSTD, CGEN, IRTDAB
or ADR
Since each encoder module is capable of supporting two audio channels
(stereo) and it is also possible to configure each channel independently
(independent mono), it is possible to route the ancillary data to either or
both channels using the EAS command:
EAS slot channel
slot
= 1,…,7
channel = LEFT, RIGHT or BOTH
G.722, as implemented in the TEAM, does not support ancillary data.
J.41 supports ancillary data through the two data ports on E1 module.
Factory default, baud rate = 9600.
Factory default, format = CGEN.
Factory default, channel = BOTH
3.4.7

Another MUSICAM USA exclusive feature available with MUSICAMEnhanced MPEG Layer 2 is Advanced Concealment of Errors (ACE).
ACE is based on CRC (Cyclic Redundancy Code) protection of the
ISO/MPEG Layer 2 scale factor.
Encoder Scale Factor Protection is controlled by the ESP command:
ESP slot mode
slot
= 1,…,7
mode
= NO or YES
Factory default = NO
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 2 types of bitstreams. Scale factor is the level of the
digital audio signal within a sub-band. There are 32 sub-bands and the
scale factors change the level over a 120 dB range. An error on any scale
3-9
TEAM U S E R S G U I D E
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 impairments.
!note:
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 TEAM’s
Scale factor protection is not compatible with other manufacturer’s
codecs. Scale factor protection is compatible with MUSICAM USA’s
CDQ2001, CDQPrima, Prima LT and Superlink codecs.
3.4.8
Sine Wave Detection
Sine wave detection should be used only when using test tones for
audio analysis with test equipment, and should be OFF for normal
operation. Sine wave detection is available only when using any MPEG
Layer 2 algorithm, and is selected using the ESD command:
ESD slot mode
slot
= 1,…,7
mode
= ON or OFF
Factory default = OFF.
3.4.9
Encoder Header and Decoder Status Bits
When using an ISO/MPEG Layer 2 compatible audio compression
algorithm, there are certain flags that may be set in the header. These
five user defined flag bits can be used by the decoder or can be used as
additional signaling paths.
The Emphasis bit is set using the EEP command:
EEP slot mode
slot
= 1,…,7

= NO, 50 or J.17
The Original bit is set using the EOR command:

3.4.10 Input Selection
The encoder modules available for use in your TEAM system are
capable of two different audio input modes: digital audio or analog
audio input.
For modules equipped with both analog and digital audio inputs,
jumpers are used to select which input source is active. (Refer to Figure
3-2.) Jumpers J3 and J4 select digital audio inputs when in position 2-3
and select analog audio inputs when in position 1-2.
Jumpers are also used to select the digital audio input format, either
AES/EBU or S/PDIF. Jumper J7, when in position 1-2 sets AES/EBU

TEAM encoder contains very high quality rate converters, and supports
32, 44.1 and 48 kHz digital audio sampling rates.

3.4.12 Analog Input Level Adjustment
The analog input clipping level is variable, in three steps. The nominal
clipping level of +18 dBu can be changed to either +15 dBu or +24 dBu
with jumpers J8, J9, J10 and J11 on the encoder module (all levels are ± 1
dB). The jumpers affect both channels simultaneously. Refer to the table
below for the proper settings of these jumpers.

upper two pins.
3.4.13 Analog Input Impedance
To make your encoder module compatible with a variety of professional
and consumer analog audio equipment, two input impedance levels are
supported. Jumpers J5 and J6 are used to change input impedance from
600Ω (position 1-2) to >12kΩ (position 2-3).

Decoder
Up to six stereo Decoder modules can be used in the TEAM
system.
4. Overview
T
he TEAM decoder module is a standard stereo audio decoder,
with a choice of analog and/or digital (AES/EBU or S/PDIF)
audio outputs and an RS-232 ancillary data channel. Numerous
algorithms and bit rates are supported, including 64 kb/s G.722, Nx64
kb/s MUSICAM-enhanced Layer 2 and MPEG Layer 3, J.41 (384 kb/s
mono), and J.57 (companded and multiplexed). If multiple encoder
and decoder modules are used, different compression algorithms can be
used for different channels simultaneously.

Decoder module
The decoder’s powerful 24-bit D/A converter insures low distortion
and high signal-to-noise ratios regardless of algorithm used. Multiple
sampling rates and output levels accommodate a wide range of devices
and bandwidths. With six installed decoder modules, it is possible to
receive up to twelve individual, high-fidelity monaural channels per
unit. Several TEAM units can be daisy-chained for up to thirty audio
channels. In addition, different configurations can be used for different
channels simultaneously.
4.1 Decoder Installation
Your TEAM system can support up to six encoder, decoder or
X.21/V.35 modules. Modules can be inserted in any free slot except the
two right-most power supply and the left-most control processor slots.
It is not necessary to remove system power when removing or inserting
decoder modules. The installation or removal of a decoder card is
automatically detected.
4-1
TEAM U S E R S G U I D E
4.2 Decoder Configuration
If a decoder module is installed in a previously unpopulated slot or a
slot that previously held another type of module, a factory default
decoder configuration is loaded. If a decoder module is installed in a
slot that previously held a decoder module, then the previous
configuration is loaded.
4.2.1
Algorithm Selection
The TEAM decoder module can decode any of the different algorithms
supported to enable you to meet any audio quality requirement, from
voice only to digital mastering quality. In addition, there is extra onboard memory for new algorithms to be installed as they are developed.
Refer to Section 3.3 (Encoder Algorithms) for a description of all
available algorithms.
The decoder algorithm is selected using the DAL command:
DAL slot algo
slot
= 1,…,7
algo
= G.722, MPEGL2,
MPEGL3, J.41, or
J.57
Factory default = MPEGL2.
4.2.2
Decoder Algorithm Modes
The TEAM decoder automatically senses the algorithm mode of the
incoming audio data, thus making algorithm mode selection
unnecessary. When monaural modes are used, the same audio can be
sent to both left and right channels.
4.2.3
Decoder Line Format
Two line formats are available, Single Line and Independent Mono.
Independent Mono is used only with monaural-only algorithms (G.722
and J.41) when stereo or independent mono operation is desired, for
example, dual G.722 and stereo J.41 (dual mono). All other algorithms
and modes should use the single line format. The decoder algorithm
mode must match algorithm mode of the connected encoder for audio
to pass from encoder to decoder. The DLI command is used to set the
decoder line format:
DLI slot line
slot
4-2
= 1,…,7
TEAM U S E R S G U I D E
line
= S or I
Factory default = Single line.
4.2.4
Decoder Bit Rate
MPEG algorithms allow a wide selection of bit rates enabling you to
select the best transmission bit rate for your application. The NMC
command is used to select the bit rate. Refer to Section 7.5.3 for
information on the NMC command.
When using non-MPEG algorithms, the bit rate is set by the algorithm
specifications.
Factory default = 384 kb/s.
4.2.5
Decoder Sample Rate
MPEG algorithms allow a range of encoder/decoder sample rates.
Under normal conditions, the decoder sample rate is slaved to the
incoming bit stream, set by the encoder, and is not adjustable. However,
upon power-up with MPEG Layer 3 at 32 kHz sampling, it may be
necessary to issue a DDO command to set the decoder sample rate. This
may be necessary since the sample rate must be set to 48 kHz to boot the
decoder.
Do not confuse encoder/decoder sample rates with digital audio
sample rates, discussed later.
4.2.6
Channel Copy/Swap and Output Muting
It may be desirable to swap the left and right channel audio outputs or
to copy one channel to the other output. The DCS command is used for
this:
DCS slot mode
slot
= 1,…,7
mode
= NORM, CLTOR, CRTOL
or SWAP
The DMU command is used to mute one or both output channels:
DMU slot mode
slot
= 1,…,7
mode
= NONE, LEFT, RIGHT
or BOTH
Factory default, copy/swap = NORM.
Factory default, decoder mute = NONE.

J.41/J17 Emphasis
If J.41 emphasis is used in encoding (turned on with the EEP command)
you must set the decoder to recognize the emphasis using the DEP
command.
Syntax:
4.2.8
DEP slot emphasis
Ancillary Data
Each decoder card has one ancillary data port that can be used to
receive RS232 data from a far-end encoder when using any MPEG
algorithm. This DB25 connector provides RS232 data de-multiplexed
from the audio data. A true three-wire data path is provided; flow
control is not provided. Data rates from 300 to 38,400 bits/sec are
supported and selected with the DDR command:
DDR slot rate
slot
= 1,…,7
rate
= 300, 1200, 2400,
4800 ,9600 or 38400
In addition to the connector on the decoder, TEAM allows you to route
decoded ancillary data to the ancillary data connector on the Command
Processor module. This requires setting the ancillary data rate on the
CP port using the CDR command as well as setting the decoder ancillary
data rate.
When present, ancillary data uses bits normally assigned to audio data.
Under most circumstances, this will not noticeably degrade the audio
performance; however, the use of high data rates with low transmission
bit rates should be avoided.
MPEG supports several ancillary data formats for compatibility with
other codecs and satellite systems. Refer to Section 7.2.1 for a
description of the different formats. The decoder ancillary data format
must be the same as the connected encoder format. Use the DAF
command to select the appropriate format:
DAF slot format
slot
= 1,…,7
format = CSTD, CGEN, IRTDAB
or ADR
4-4
TEAM U S E R S G U I D E
Since each decoder module is capable of supporting two audio channels
(stereo), it is necessary to route the ancillary data to either channel when
using monaural modes using the DAS command:
DAS slot channel
slot
= 1,…,7
channel = LEFT or RIGHT
G.722, as implemented in the TEAM, does not support ancillary data.
J.41 supports ancillary data through the two data ports on E1 module,
and J.57 supports AES/EBU ancillary data only.
Factory default, baud rate = 9600 kb/s.
Factory default, format = CCS Generic.
Factory default, channel = RIGHT.
4.2.9
MPEG Layer II Scale Factor Protection (Error Concealment)
Another MUSICAM USA exclusive feature available with MUSICAMEnhanced Layer 2 is Advanced Concealment of Errors (ACE). ACE is
based on CRC (Cyclic Redundancy Code) protection of the ISO/MPEG
Layer 2 scale factor.
Decoder Scale Factor Protection is controlled by the DSP command:
DSP slot mode
Slot
= 1,…,7
Mode
= YES or NO
In general, it is better to use scale factor protection if the data channel is
noisy (high BER). Scale factor protection (DSP) is used for all
ISO/MPEG Layer 2 types of bitstreams. Scale factor is the level of the
digital audio signal within a sub-band. There are 32 sub-bands 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 impairments.
!note:
If the decoder has enabled scale factor correction, the far end encoder
must enable scale factor protection with the ESP command. If only
one end has scale factor protection enabled, audio may be muted. The
TEAM’s Scale factor protection is not compatible with other
4-5
TEAM U S E R S G U I D E
manufacturer’s codecs. Scale factor protection is compatible with
MUSICAM USA’s CDQ2001, Prima LT, CDQPrima, and Superlink
codecs.
When Scale Factor Protection is activated, only ancillary data modes
CCS Standard and CCS Generic are supported.
Factory default = NO.
4.2.10 MPEG Layer II Decoding Mode
Two MPEG Layer 2 decoding modes are available for compatibility
with CCS Audio Products codecs manufactured before ISO/MPEG
standardization. Under normal operation, ISOCCS mode should be
used, unless an older CCS codec is used at the far end. Use the DCO
command to change formats:
DCO slot fmt
Slot
Fmt
= 1,…,7

Factory default = ISOCCS.
4.2.11 Output Selection
All decoder modules are equipped with both analog and digital
outputs. To change output type, use the DAO command:
DAO slot output
slot
= 1,…,7
output
= ANALOG or DIGITAL
You must also use jumpers to select which output is active. Jumpers J3,
J4, J14 and J15 are used to select the audio output, analog or digital.
When all of these jumpers are in position 1-2, analog output is selected.
When these jumpers are in position 2-3, digital output is selected.
Jumpers are also used to select the digital audio output format,
AES/EBU or S/PDIF. Jumpers J2 and J5, when in position 1-2 select
AES/EBU, and when in position 2-3 select S/PDIF. Please note that
digital audio I/O is not supported when using G.722.
Digital audio output sample rate, not to be confused with the
encoder/decoder sample rate, is selected using the DDO command:

the E1 digital network. E1 is the 2.048 Mb/s standard used
everywhere except North America (E1 may be available in some areas
of North America).
This module provides access to up to three E1 circuits: timing E1, a

The primary network
interface port is the bidirectional ‘Main’ E1
port. Audio data from
the TEAM encoders is
multiplexed with data
from the Drop/Insert
(D/I) port and the two
user data ports and is
output through the Main E1 port. Conversely, data coming into this port
is demultiplexed and sent to the appropriate location, decoders,
Drop/Insert port, or the user data interfaces. In the example shown
here, n audio channels are multiplexed into one E1 interface. The
maximum number of (single direction) audio channels depends on the
bit rates of each channel, and the number of encoder/decoder modules
installed. E1 has thirty-two channels, each 64 kb/s. 30 channels are
available for audio( 2 channels overhead). For example, if using 384
kb/s audio channels, five is the maximum number of channels with E1.

Another key function of the E1 module is the capability to drop and
insert data traffic to and from the primary network interface. Data to
and from the bi-directional D/I interface is multiplexed/demultiplexed
with other audio and ancillary data internally in this module.

dropped and decoded at location ‘A’, and two audio channels for
location ‘B’ are inserted.
While the D/I port’s primary function is to accept drop/insert data, it is
electrically identical to the main E1 port. Therefore, it can be used as a
second primary E1 interface, allowing the transmission of the same
audio to two locations for each interface module installed.
All connections between the Drop/Insert Port and the Main E1 Port are
controlled using the NMD for establishing the connections and the NRD
command for removing the connection:
NMD source dest rate changrp
= Source slot, port
slot = 1,…,7
port = N or D
= destination slot, port
slot = 1,…,7
port = N or D
= Bit rate, N x 64
N = 1,…,30
= Channel group, 1,…,74

Connections between the Drop/Insert Port and the Team Encoder,
Decoder, X.21, or Control Processor modules are also possible, and are
controlled using the NMC command to establish, and the NRC
command to remove these connections, with the D port value specified
for the Drop/Insert Port. Selecting the Command Processor port ‘A’ as
a destination enables TEAMs streaming audio capabilities, discussed in
later chapters.

Table 5-2 — Timeslot Assignment for E1
5.2.3
E1 Cable Requirements
There is no recommended manufacturer or type of cable that must be
used for E1 connections. The only limitation on cable selection is that
the cable attenuation should not exceed 6dB at 2 MHz, end-to-end.
Therefore, maximum cable length depends entirely on the specifications
of the cable selected.

User (Ancillary) Data Ports
The two User Data ports, wired identically, are configured for V.24
asynchronous bi-directional data. The pins used determine the interface
used. These ports are independent of the TEAM’s audio
encoder/decoder functions.
Port data is retrieved or inserted from/to time slots on the TEAM
backplane. Since these data ports are configured as DCE devices in
operation, they are always considered as the clock master, and will not
accept an input clock from an external device.
The asynchronous V.24 ports, electrically equivalent to RS232, are
limited to data rates of 9600 kb/s or less. The data rate adaptation is
automatic.
Unlike X.21 data, which can be inserted in any available time slot, the
V.24 data is inserted into time slot 16 only. This is the limiting factor as
to data speed.

Table 5–3 User Data Port Pin Connections
The ancillary data ports can be configured for asynchronous V.24 data.
X.21 support will be added in the future.
There are 5 possible V.24 modes, selected with the NVM command:
NVM slot port mode
slot
port
mode
= 1,…,7
= 0 or 1
= INACTIVE, TX, TXRX,
TS16RXTX or
TS16TXONES
When not used, the port mode should be set to Inactive. The TX mode
is used to send V.24 data to the E1 transmit only. The TxRx mode sets
up for bi-directional data from the E1 transmit and receive. In addition
to receiving the V.24 data, the TS16RXTX mode will forward V.24 data
from the E1 receive to the E1 transmit. The TS16TXONES mode is the
same as the TX16RXTX mode except that all ‘1’s are forwarded to the E1
transmitter.
The ancillary data can be routed to a far-end TEAM or Superlink system
through either the main Network E1 interface or the Drop/Insert E1
interface. The NVC command is used to select the E1 interface:
NVC slot port

5.3 Sync (Timing) Source
There are four possible timing sources that can be used as a master
clock for the TEAM system. Internal timing uses an internal crystal for
synchronization. Timing can also be derived from the Main E1 port, the
Drop/Insert E1 port or the Timing E1 port. The NSS command is used
to select the active timing (sync) source:
NSS slot sync
= 1,…,7
= INT, RXTIMING, RXNETWORK
or RXDROPINSERT
If several TEAM units are working in a daisy-chain configuration, it is
important that every unit is synchronized to a single master clock. This
can be the internal, E1, Drop/Insert or an external clock. If daisychaining the clock, be sure not to make a ring, or circle, configuration.
One TEAM cannot receive the timing from two E1 sources; e.g., you
cannot output audio coming in through E1 and Drop/Insert ports
simultaneously unless the unit feeding the Drop/Insert port has the
exact same timing as the receiving unit.

5.4 Time-Slot 16 Master Framing
Time slot 16 is used for the transmission of ancillary data when the J.41
algorithm is used. Ancillary data from the two ports on the E1 module
uses the capacity of this time slot for transmission to the far-end data
ports
Master framing of this signal is controlled using the NTM command:
NTM slot frame

5.5 CRC4
CRC4 error protection, optionally selectable, uses a single bit in
alternate frames of the E1 bit stream to form a CRC calculation of a

the frame alignment signal.

5.6 Default Configuration
A factory default configuration is loaded whenever a multiplexer
module is installed in a slot not previously occupied with a multiplexer
module. A factory default configuration cam be loaded at any time
using the CDF command:

Status Monitoring
There are five status LEDs on the E1 module:
•
The Master LED illuminates when the E1 module is used for
system timing
•
The E1 Clk and E1 LED’s:
o Illuminate GREEN when there is a signal at the interface
AND the module can synchronize to that signal AND the
interface is selected as the sync source AND the module is
selected as clock master for the system
o Illuminate RED when there is NO signal at the interface
(Loss Of Signal) OR (the interface is selected as the sync
source AND the board cannot synchronize to the signal)
o Are OFF if there is no signal at the interface (LOS) AND
(the interface is not selected as the sync source OR the
board is not selected as clock master for the system)
•
The AIS LED illuminates when an all ‘ones’ signal is received
from the E1 network
•
The SYNC LED illuminates when the E1 module is unable to
achieve synchronization from the selected source
The status of all other module functions, including used and free time
slots, add/drop, multiplex and alarm functions is obtained through the
Control Processor module.

his plug-in module is designed to provide all of the multiplexing
and interface functions required to connect the TEAM system to
the T1 digital network. T1 is the 1.544 Mb/s standard used in
North America, whereas E1 is the 2.048 Mb/s standard used
everywhere except North America. For connection to the E1 digital
network, an E1 Multiplexer card is required.
This module provides access for up to three T1 circuits: timing T1, a
drop/insert T1 and a main channel T1. The two user data ports can be
configured for X.21 or V.24 protocols; however, V.24 is not available
with this software revision.
6.1 Multiplexer Installation
The T1 multiplexer module can be installed in any free slot except the
left-most control processor and the two right-most power supply slots.
Multiple T1 modules can be installed, and it is not necessary to turn the
TEAM system off to remove or install a T1 module.
6.2 Front Panel Connectors
Three network connectors; a test connector and two user data ports are
located on the T1 module front panel.

The three T1 ports, Main (T1), Drop/Insert, and Timing (T1 Clock) are
all wired identically. Each connection uses the standard 120Ω
symmetrical interface.
Connector pinouts are shown in Table 6-1A. A built-in CSU allows the
T1 multiplexer to be connected directly to the network without an
external CSU/DSU.

TEAM U S E R S G U I D E
The T1 timing interface allows connections to the network, but unlike
the other two interfaces, this interface is used only to derive network
timing. This includes both bit clock and frame sync information. This is
a receive-only interface and does not have a built-in CSU/DSU. The
DS1 external clock signal goes to the Drop/Insert port and has internal
CSU/DSU support. If the Drop/Insert function is required in addition
to external DS1 clock, two TEAM units can be used with the external
clock driving the first unit and the timing of the second unit derived
from its Drop/Insert port.
The primary network
interface port is the bidirectional ‘Main’ T1
port. Audio data from
the TEAM encoders is
multiplexed with data
from the Drop/Insert
(D/I) port and the two
user data ports and is
output through the Main T1 port. Conversely, data coming into this
port is demultiplexed and sent to the appropriate location, decoders,
Drop/Insert port, or the user data interfaces. In the example shown
here, n audio channels are multiplexed into one T1 interface. The
maximum number of (single direction) audio channels depends on the
bit rates of each channel, and the number of encoder/decoder modules
installed. T1 has a maximum capacity of twenty-four 64 kb/s channels.
For example, if using 384 kb/s audio channels, four is the maximum
number of channels with T1.
Another key function of the T1 module is the capability to drop and
insert data traffic to and from the primary network interface. Data to
and from the bi-directional D/I interface is multiplexed/demultiplexed
with other audio and ancillary data internally in this module.

DROP / INSERT FUNCTION
As an example, in a three-location setup, location ‘A’, the central
location, is connected to location ‘B’ (Main T1 port) and to location ‘C’
through to the D/I port as shown here. There is no direct link between
locations ‘B’ and ‘C’. Location ‘C’ sends several channels of audio to
location ‘B’ through location ‘A’.
One audio channel from ‘C’ is
dropped and decoded at location ‘A’, and two audio channels for
location ‘B’ are inserted.
While the D/I port’s primary function is to accept drop/insert data, it is
electrically identical to the main T1 port. Therefore, it can be used as a
second primary T1 interface, allowing the transmission of the same
audio to two locations for each interface module installed.
In addition to the multiplexing and drop/insert functions, a cross
connect function is also provided. It is possible to use one centrally
located TEAM unit as the hub of a star-configured network. As an
example, shown here, one central TEAM unit is connected to six remote
locations. The cross connect function allows any remote location to
send audio to any other remote location without the need to decode and
encode at the central location.
All connections between the Drop/Insert Port and the Main T1 Port are
controlled using the NMD for establishing the connections and the NRD
command for removing the connection:

T1 Cable Requirements
There is no recommended manufacturer or type of cable that must be
used for T1 connections. The only limitation on cable selection is that
the cable attenuation should not exceed 6dB at 2 MHz, end-to-end. In
order to properly configure the internal CSU, you need to know the
approximate cable length.

User Data Ports
The two User Data ports, wired identically, are configured for either
X.21 synchronous or V.24 asynchronous bi-directional data. The same
connector is used for both V.24 (electrically equivalent to RS232) and
X.21. The pins used determine the interface used. These ports are
independent of the TEAM’s audio encoder/decoder functions.
Port data is retrieved or inserted from/to time slots on the TEAM
backplane. Since these data ports are configured as DCE devices in
operation, they are always considered as the clock master, and will not
accept an input clock from an external device.
The asynchronous V.24 ports, electrically equivalent to RS232, are
limited to data rates of 9600 kb/s or less. The data rate adaptation is
automatic.
Unlike X.21 data, which can be inserted in any available time slot, the
V.24 data is inserted into time slot 16 only. This is the limiting factor as
to data speed.

6.3 Sync (Timing) Source
There are four possible timing sources that can be used as a master
clock for the TEAM system. Internal timing uses an internal crystal for

TEAM U S E R S G U I D E
synchronization. Timing can also be derived from the Main T1 port, the
Drop/Insert T1 port or the Timing T1 port. The NSS command is used
to select the active timing (sync) source:
NSS slot sync
= 1,…,7
= INT, RXTIMING, RXNETWORK
or RXDROPINSERT
If several TEAM units are working in a daisy-chain configuration, it is
important that every unit is synchronized to a single master clock. This
can be the internal, T1, Drop/Insert or an external clock. If daisychaining the clock, be sure not to make a ring, or circle, configuration.
One TEAM cannot receive the timing from two T1 sources, e.g., you
cannot output audio coming in through the main and Drop/Insert ports
simultaneously unless the unit feeding the Drop/Insert port has the
exact same timing as the receiving unit.

Status Monitoring
There are five status LEDs on the T1 module:
•
The Master LED illuminates when the T1 module is used for
system timing
•
The T1 Clk and T1 LED’s:
o Illuminate GREEN when there is a signal at the interface
AND the module can synchronize to that signal AND the
interface is selected as the sync source AND the module is
selected as clock master for the system
o Illuminates RED when there is NO signal at the interface
(Loss Of Signal) OR (the interface is selected as the sync
source AND the board cannot synchronize to the signal)
o OFF if there is no signal at the interface (LOS) AND (the
interface is not selected as the sync source OR the board is
not selected as clock master for the system)
•
The AIS LED illuminates when an all ‘ones’ signal is received
from the T1 network
•
The SYNC LED illuminates when the T1 module is unable to
achieve synchronization from the selected source
The status of all other module functions, including used and free time
slots, add/drop, multiplex and alarm functions is obtained through the
Control Processor module.

Timing/Synchronization Source Select
There are four possible timing sources that can be used as a master
clock for the TEAM system. Internal timing uses an internal crystal for

You can also use this command to display the current setting.
If several TEAM units are working in a daisy-chain configuration, it is
important that every unit is synchronized to a single master clock. This
can be the internal, T1, Drop/Insert or an external clock. If daisychaining the clock, be sure not to make a ring, or circle, configuration.
One TEAM cannot receive the timing from two T1 sources; e.g., you
cannot output audio coming in through T1 and Drop/Insert ports
simultaneously unless the unit feeding the Drop/Insert port has the
exact same timing as the receiving unit.

the TM-3BRIx ISDN Terminal Adapter supports up to 3 ISDN
BRIs for multiple audio connections. Supporting both S/T and U
interfaces, the TM–3BRIx can be used anywhere in the world that
ISDN is available.
7.1 Installation
The TM–3BRIx module can be installed in any available slot, and is
automatically recognized by TEAM. There are no user settable
jumpers. The TM–3BRIx can be purchased with one (TM–3BRI1), two
(TM–3BRI2) or three (TM–3BRI3) BRI connections installed. At least one
BRI must be initially installed, and additional BRIs can be installed in
the field, with the addition of daughter boards.

ISDN Cable Requirements
Both the S/T and U interfaces have RJ-45 connectors. Standard ISDN
wiring practices should be observed, bearing in mind that multiconductor phone wire is required for connections to the S/T interface.
The U interface requires only two-conductor cable as only the center
conductors of the RJ-45 connector are used.
Sometimes, the telephone company may provide only a four-wire RJ-11
connector for the U interface. If you don't have an RJ-11 to RJ-45
adapter cord, a standard RJ-11 plug will fit into the RJ-45 jack on the
TM-3BRI.
7-1
TEAM U S E R S G U I D E
Note!
Proper ISDN Circuit
wiring is critical for
dependable
operation
Although, depending on wire quality, your TEAM can be located
thousands of feet from the Telco termination; you should attempt to
keep line lengths as short as possible.
Unlike standard phone circuits, extension lines are not permitted with
IDSN. You cannot have an ISDN line service to two rooms. Splices
should be avoided as well. MUSICAM USA strongly recommends that
existing building phone wiring not be used for ISDN since in most cases
you cannot tell if there are splices or extensions, especially in older
buildings.
The TM-3BRI must be configured before it can be used. Since each BRI
is configured independently, they can each be configured for different
locations or different countries, using the appropriate BRI for the
current location.
7.2
Configuration for use in North America
Each BRI within the TM-3BRIx ISDN interface module must be
configured for use in a particular country and identified (to the
telephone Central Office) before it can be used. If the TM-3BRI interface
module is equipped with more than one BRI, each BRI can be
configured for a different country, making the TEAM true 'plug-andplay'.
Each BRI provides both S/T and U interfaces. For North America, the
‘U’ interface is used, with a built-in NT-1 (required for North American
operation).
Probably the most confusing aspect of ISDN codecs is configuring the
Terminal Adapter for the ISDN in your area. This is especially true in
North America, where there are several local ‘flavors’ of ISDN that are
all provisioned differently. Elsewhere, configuration of the terminal
adapter may be as simple as insuring the proper country is selected.
In North America, the ISDN service provider must supply certain
information to allow you to correctly configure the Terminal Adapter:
ISDN ‘Flavor’, e.g. National ISDN or Custom.

Service Provider Identification Numbers (SPID numbers). National
ISDN (NI1) always requires SPID numbers; some locations using
Custom ISDN may not require SPID numbers. If SPID numbers are
required, most areas use two, but some implementations require only
one.
7.2.1
Switch Type:
It is necessary to tell the TA what type of switch protocol is being used
at the Telco central office. The ISDN service provider will give this
information to you. You need to set the switch type only once for each
BRI, a maximum of three, since it is impossible to have different switch
types for the individual “B” channels in an ISDN line. Set the
appropriate switch type, either National or AT&T Custom using the
CSW Command from a terminal.
Set ‘5ESS CUST’ only for AT&T custom point-to-point or point-tomultipoint ISDN service available in a limited number of areas in the
United States. For all other ISDN service, including AT&T National
ISDN, select ‘NI1’.
Use the CSW command to set the Switch Type for any or all of the BRIs.

Service Provider ID (SPID) Number:
After the switch type is entered, you will then be prompted to enter two
SPID numbers for each BRI installed, up to a maximum of six.
For most areas in North American, the TA must be told the SPID
number of the calling ISDN line, that is, the line to which the TEAM is
connected, i.e., your ISDN line. The ISDN service provider in your area
provides this number to you. It is important to remember that every
time the TEAM is moved, or whenever there is a change in the ISDN

If SPIDs are not used in your area, line 2 may answer the first incoming
call and line 1 will answer the second.
Once both SPID numbers are entered you will be prompted to enter
Identification (ID) numbers.
7.2.3
Identification (ID) Number:
If you are required to use two SPID numbers per BRI, then you must
use ID numbers as well. For North American operation, the ID number
is just the seven-digit ISDN line number connected to the TM–3BRIx.

Configuration for International Operation
Each BRI within the TM-3BRIx ISDN interface module must be
configured for use in a particular country and identified (to the
telephone Central Office) before it can be used. If the TM-3BRI interface
module is equipped with more than one BRI, each BRI can be
configured for a different country, making the TEAM true 'plug-andplay'.
7-5
TEAM U S E R S G U I D E
Each BRI provides both S/T and U interfaces. For North America, the
‘U’ interface is used, however, everywhere else, the 'S/T' interface is
used.
Probably the most confusing aspect of ISDN codecs is configuring the
Terminal Adapter for the ISDN in your area. Even in the same country
or region, there may be several local ‘flavors’ of ISDN that are all
provisioned differently. Elsewhere, configuration of the terminal
adapter may be as simple as insuring the proper country is selected.
7.3.1
Switch Type:
It is necessary to tell the TA what type of switch protocol is being used
at the Telco central office. DSS1 is most commonly used in European
countries, and JATE is used in Japan and other Pacific-Rim countries.
You need to set the switch type only once for each BRI, a maximum of
three, since it is impossible to have different switch types for the
individual “B” channels in an ISDN line.
Use the CSW command to set the Switch Type for any or all of the BRIs.

If using the TM-3BRI in Germany, it may be necessary to select 1TR6 as
the switch protocol. The ISDN service provider will give this
information to you.
7.3.2
LDN / MSN Number:
The MSN (Multiple Subscriber Number) allows you to connect several
codecs (terminal adapters) to one ISDN bus, if the DSS1 Euro-ISDN
protocol is used. Each BRI requires two MSN numbers, one for each 64
kb/s channel. You do not need to enter the whole MSN, you just have
to enter the last different digits. For example, if your MSN for line 1 is
8115517571 and for line 2 is 8115517581, then you only need to enter ‘71’
and ‘81’ for the MSNs. Use the CLD Command to set the LDN/MSN

Sub-addresses are required when using the German 1TR6 switch
protocol. Like the MSN used with DSS1, the sub-address enables you to
connect several codecs (terminal adapters) to the same ISDN bus. For
every terminal adapter, you need two sub addresses (EAZ numbers),
one for each 64 kb/s channel, numbers between 1 and 8. Use the CSA

Making connections to and from TM-3BRI
Connections between the TM-3BRI and the Team Encoder, Decoder, or

X.21 and V.35 Interfaces
Connect your TEAM system to external codecs and other devices
through industry standard X.21 or V.35 interface ports.
8. Overview
T
hese plug-in modules provide an industry standard interface to
other devices and systems. Providing access to the TEAM’s TDM
backplane bus, the X.21 or V.35 Interface allows external devices,
such as processing and coding equipment, to be connected to the E1 or
T1 interfaceX.21 or V.35 Installation
The X.21 or V.35 interface module can be installed in any free slot
except the left-most control processor and the two right-most power
supply slots. Multiple X.21 and/or V.35 modules may be installed, and
it is not necessary to turn the TEAM system off to remove or install an
X.21 or V.35 module.

Table 8–2 V.35 Port Pin Connections
The TEAM may be equipped with X.21 and/or V.35 interface modules
for ISDN, leased circuits, and other transmission media. In addition,
since the RS422 interface is electrically compatible with industry
standard RS449 equipment, the TEAM’S X.21/RS422 adapter can be
8-2
TEAM U S E R S G U I D E
used with RS449 equipment with the addition of an adapter cable. Each
of these digital interfaces requires clock and data to be exchanged
between the TEAM and the terminal equipment. The TEAM always
expects the clock to be provided by the terminal equipment;
therefore, only terminal equipment that provides clock data can be
used. The encoder section outputs data synchronized with the clock
and the decoder expects the data to be synchronized with the clock.
The data and clock lines are differential, and require a pair of wires for
each signal. The control lines in the V.35 interface are single-ended and
require only one wire for each signal. The X.21 control lines are
differential. The RS422 interface does not support any control lines.
Any RS422 input control lines defined are ignored by the TEAM and
any output control lines defined are held at constant values.
When using X.21, RS422 or V.35 interfaces, the TEAM is configured as
a DTE device
8.2 X.21 and V.35 Configuration
Since an X.21 or V.35 module can be configured as a Local module, the
NMC/NRC command(s) must be used to assign a type and address to the
module. These same commands also define the X.21 or V.35 module’s
Channel Group, bit rate, Lift and Drop Subchannel ID. Each X.21 or
V.35 module has two ports, which are individually configurable.
8.2.1
X.21 and V.35 Default Configuration
A factory default configuration is loaded whenever an X.21 or V.35
module is installed in a slot not previously occupied by an X.21 or V.35
module. The factory default configuration can also be loaded at any
time using the CDF command:

Y
ou can perform all functions, including configuration,
monitoring, and maintenance using a computer or terminal
connected to the TEAM system M&C ports.
In addition, the Telnet server is now enabled in the CP code, allowing
Ethernet control of the CP as well as high-speed downloads of the
software. Any Telnet client can be used to communicate with the CP
through the Ethernet port, but note that not all Telnet clients support
file transfer. The address for Telnet communications is the CP’s IP
address with a port number of 2000. A tested Telnet application for the
CP control and software download is HyperTerminal.
This feature can also enable multiple TEAM units to be controlled by a
single PC terminal using multiple instances of HyperTerminal.
Alternately, a single TEAM unit can be controlled from multiple sites
via the Ethernet

If any timing source should fail or become unstable,
TEAM will automatically fall back to the next available
source.

The factory default sequence is N, D, S I, but this can be
changed using the CMT command. If the current sync
source is lost, the TEAM system will switch to the next

restored, the TEAM system will revert back to that source
automatically.

Set Digital Audio Output Sampling Rate
Digital audio is output from the decoder at the sampling
rate specified in the header. This digital audio output,
sampled at the selected rate, can be used directly, or can
then be converted to other rates via an external sample
rate converter.
The internal sample rate converter is capable of sampling
rate changes between 0.51 and 1.99. For example, if the
decoder received a bit stream that indicated that the
encoder sampling rate was 24 kHz, then the output
sampling rate could be set to 32 or 44.1 kHz but not 48
kHz since 48 kHz would be a sampling rate conversion of
2.0 to 1. This is out of the range of the sampling rate
converter.
The following table outlines the valid sampling rate
conversions:

48 kHz
For MPEGL2 and MPEGL3 algorithms only, the Decoder
automatically sets the audio sampling rate to the rate in
the received bit stream. The received audio sampling rate
is sampled at intervals equal to the audio poll timer
period. This timer period may be changed using the XPO
command. The received audio sampling rate is updated
in NVRAM for MPEGL2, the last stored value is applied
on re-powering. The sampling rate is not stored in
NVRAM for MPEGL3 because this algorithm
implementation requires a setting of 48 kHz at power-up
and will not function properly for other settings. The DDO
command can be used to independently set the Decoder
audio sampling rate to either 48kHz or 32 kHz. This
sampling rate is also stored in NVRAM. During
transmission it is overridden by the received sampling
rate. The automatic resetting of audio sampling rate does
not apply to other compression algorithms (which feature
fixed audio sampling rates at 16kHz, 32kHz and 48kHz for
G.722, J.41 and J.57 respectively)

Enable Decoder AES Sync Timing
Definition: This command is used to enable/disable the
use of the decoder AES/EBU sync signal. Normally, the
AES/EBU sync signal for the decoder is used to determine
the rate of the output of the AES/EBU decoder output.
The AES/EBU decoder sync input can be ignored by
setting es to NOTREQ.
If there is no signal present at the decoder sync input, or
DES is set to DISABLE, then the D/A converter and the
AES/EBU transmitter in the decoder derives its timing
from the network clock. The exact value of the clock is
phase locked to the network clock at a rate given by
information in the received ISO/MPEG data stream.
If there is a sync signal present at the decoder sync input,
then the signal going to the decoder D/A converter and to
the AES/EBU transmitter is rate adapted to the frequency
of the received sync input. This insures that the AES
output is in sync with the external digital audio
equipment.

Set Encoder Custom Ancillary Data Mode For T1
The EAC command is used for a custom mode of ancillary
data. This mode, called “McCurdy Mode” is compatible
with Prima series codecs at the receiving end. This mode
is supported only when using MPEG Layer 2 audio
coding.
The McCurdy mode is a custom mode for ancillary data
transmission. It enables the transmission of multiplexed
relay switch information coded in the special McCurdy
protocol and presented as an RS-232 data stream.
McCurdy formatted contact closure input data is fed to the
ancillary data port of the Encoder module. After
processing by the Encoder, the data is transmitted in the
embedded ancillary data channel of the encoded audio. At
the receiver, a specialized decoder extracts the relay
switch data from the ancillary data stream and then drives
the output relay switches. The TEAM unit allows each
Encoder module to send a separate McCurdy data stream
so multiple streams can be carried using a single TEAM
unit.

Set Encoder Sine Wave Detector
This command enables or disables the encoder sine wave
detector. If the sine wave detector is enabled, then typical
objective measurements such as THD will show the
quality of the analog circuitry and not the effects of MPEG
compression.
Sometimes the sine wave detector can be activated by rare
passages of music, which may result in a slight distortion
of the passage. Turning the sine wave detector off
prevents false sine wave detection. However, turning off
the sine wave detector may cause poorer objective
measurements when using test signals.
Note:
Turning the sine wave detector off, in no way, harms the
MPEG audio compression algorithm and may improve
subjective audio quality. The sine wave detector should
be turned OFF for normal operation.

Definition:
This command is used to write any unwritten bytes to
nonvolatile memory. Many of the variables that are kept
in nonvolatile memory are first written to standard RAM
and at a later time they are flushed to battery-backed-up
RAM (BBM). This command forces all bytes that are in
RAM but not in BBM to be written to non-volatile
memory. This command can be issued just before turning
off the power to insure that all "dirty" bytes are written to
RAM.

Chapter
Operation Overview
One appropriately equipped TEAM system can accommodate
point-to point audio transmission or large-scale network systems.
10. Configuration
T
his chapter will show how to program and use the TEAM system.
Written in a tutorial format, this chapter shows how to program
the modules and connections for bi-directional audio and
ancillary data over a T1 or E1 network.
All examples in this chapter will be relative to a TEAM system
consisting of two Encoder cards, one Decoder card, an E1 multiplexer
with a E1 line and a Drop/Insert line, an X.21 card and a Control
Processor.
10.1 Send Audio Configuration
In this example, we will be using the Encoder card in Slot 2 to send
MPEG Layer 2 stereo audio at 384 kb/s. We will also be sending
independent mono (stereo) G.722 audio to the same location from the
Encoder card in slot 3.
First, we need to configure the Encoder in slot 2 for our configuration.
We must enter the selected algorithm, mode, sample rate and line
format:
EAL
EAM
ELI
ESR

TEAM U S E R S G U I D E
Next, we must map the Encoder through the backplane to the E1
multiplexer. In this example, we will be using a bit rate of 384 kb/s, 6 x
64), Channel Group 5.
map encoder (slot 2) to
the network port of the
E1 module in slot 5
using six 64 kb/s
channels, and assign to
channel group 5.
NMC 2A 5N 6 5
Next, we’ll program the Encoder in slot 3 for dual G.722, since G.722
only supports 16 kHz sampling, we do not have to set this parameter:
set algorithm
set mode
set line format
EAL 3 G.722
EAM 3 M
ELI 3 I
Next, we must map the Encoder through the backplane to the E1
multiplexer. In this example, we will be using a bit rate of 128 kb/s, (2 x
64), Channel Group 6.
map encoder (slot 3) to
the network port of the
E1 module in slot 5
using two 64 kb/s
channels, and assign to
channel group 6.
NMC 3A 5N 2 6
10.2 Receive Audio Configuration
Continuing with the above example, we will now configure the Decoder
card in slot 7 to receive MPEG Layer 2 at 384 kb/s using channel group
5:
set algorithm
set line format
DAL 7 MPEGL2
DLI 7 S
Note that the Decoder mode and sample rate need not be set since these
are slaved to the incoming audio.
10-2
TEAM U S E R S G U I D E
Next, we must map the Decoder through the backplane to the E1
multiplexer. In this example, we will be using a bit rate of 384 kb/s, (6 x
64), Channel Group 5.
map the Network port
of the E1 multiplexer in
slot 5 to the Decoder
module in slot 7 using
six 64 kb/s channels,
and assign to channel
group 5.

10.3 Ancillary Data Setup
In addition to the bi-directional audio, we also want bi-directional
RS232 ancillary data. Since G.722 does not support ancillary data, we
will be using the MPEG Layer 2 channels for this.
In this case, we will be sending data at 9600 baud, using the ancillary
data connector in the front of the Encoder module in slot 2. For return
data, we will be using the first port on the Control processor module.
First, we set the baud rates:
Set the Encoder ancillary data
baud rate
Enable CP port A
Set the CP port A baud rate to
9600
EDR 2 9600
CAN A NOMUX
CDR A 9600
Now, map the ancillary data ports:

10.4 E1 Drop/Insert Configuration
In this example, we will set up a bi-directional 768 kb/s channel that
passes through the E1 multiplexer Network port to the Drop/Insert
port.
NMD 5N 5D 12 7
Set up connection Network
port to Drop/Insert port
NMD 5D 5N 12 7

10.5 X.21 Configuration
For our last configuration example, we want to configure an X21 port
for 64 kb/s output from Channel Group 1 of the main Network E1. The
X.21 card has been installed in slot 6, and we want to configure port ‘A’
of this card.
NMC 5N 6A 1 1
Had there been a V.35 module instead of the X.21 module, the
configuration steps would have been identical
10.6 Software Installation and Upgrade
All system functions, including audio compression algorithms, can be
easily updated as new features or functions become available. The CP
supports system upgrades through the RS232 M&C port using any
asynchronous communications package with an “upload” feature. Two
examples of acceptable packages are Procomm Plus® and
Hyperterminal® (Microsoft Windows). Port baud rates up to 38,400 are
supported.
There are four categories of software used in the TEAM codec: CPBOOT
(Boot software), CPSYS (system software), DSP software (Encoder and
Decoder) and FPGA Logic (multiplexing functions). There may be
many individual software modules (referred to as “THINGS”) in each
software category.

In all cases, when new software is required, installation instructions will
be packaged with the software.

TEAM U S E R S G U I D E
Streaming Audio
With a connection to a Windows NT or 2000 server, TEAM
becomes the backbone for multi-channel MPEG Layer 3
streaming audio
11. Overview
T
he TEAM system can be the backbone of a multi-channel MPEG
Layer 3 audio server. All Layer 3 bit rates between 64 and 320
kb/s are supported, as is 32 or 48 kHz sampling. Only the
number of encoder modules limits the number of audio channels. A
fully loaded TEAM can therefore support twelve audio channels, and
multiple TEAM mainframes can be stacked to support many more
streams. Each encoder module can operate at a different bit or sample
rate. Equip the TEAM with decoder modules as well, and you can even
stream audio received from anywhere in the world!
11.1 Listener Requirements
For the listener, there are no special requirements other than Windows
Media Player version 7.0 or later (and a processor capable of supporting
this) and access to a network at a rate faster than the streaming bit rate.
For example, for streaming audio at 64 kb/s, a dial-up modem
connection is not acceptable, even at 56 kb/s.
11.2 The Server
Connect the 10 base-T network port on the TEAM’s Control Processor
module to a network interface port on a Windows NT or 2000 server
using a straight-through CAT-5 cable. Do not use ‘crossover’ cables. In
almost all instances, this connection would be made through a hub or
router. If no router or hub is used, at least two NICs are required in the
11-6
TEAM U S E R S G U I D E
server. As with all network connections, care must be used with respect
to wire, connector quality and cable lengths.
The minimum server requirements are:
Processor
Processor speed
Memory
Operating system
Pentium class
≥ 233 MHz
≥ 64 K
Windows NT, ≥ SP5 (SP6 recommended),
Windows 2000
Table 11-1 Server System Requirements
Currently, the maximum number of connections supported is 16.
The software required for the Format Server can be obtained from
MUSICAM USA. Install the three files using our self-extracting
installer. Once installed, there are three files associated with the server:
•
FormatServe.exe – This executable retrieves streams of audio
from a TEAM and makes it available to the Windows Media
Server/Player. It can be configured to accept audio from any
TEAM unit visible on the network and make this audio available
on any port number, to which the Media Server must connect. It
is this program with which the user interacts.
•
FormatServer.hlp – This is an on-line help file
•
StreamChan.exe – This is an executable utility, and this file must
be in the same directory (folder) as FromatServe.exe. The act of
starting and stopping an audio stream starts and stops this
process.
An additional Windows media Format encoder file, WMFDist.exe, is
needed for the NT or 2000 server, and is available at no cost from
www.tucows.com or MUSICAM USA.
11-2
TEAM U S E R S G U I D E
11.3 TEAM Setup
The TEAM, in addition to having a network card (T1 or E1) installed,
must be given an IP address as well. If not already set at the factory
(contact MUSICAM USA to find out), you can set the IP Addres s using
the XIA Command.
Note:
XIA n.n.n.n:sn
The TEAM must
be re-booted
following any
change to the IP
address
n.n.n.n
= IP address wher n=any decimal
number from 0-255
Sn=Subnet
Mask
= Sunnet mask entered in Hex
format
XIA ? - Show current internet address
Sample:
Set IP address to 155.155.155.1 with a Subnet
Mask of 255.255.255.0
XIA 155.155.155.1:ffffff00
The IP address can also be set manually, as follows:
•
Turn on the TEAM unit or re-boot if already on.
•
When the display says "Press any key to stop auto-boot...” stop the
boot by hitting any key on the console attached to the TEAM. At
that point, the following prompt should appear:
CP BOOT>
•
Use the 'c' command to single-step through the boot parameters
After typing ‘c’ and hitting the return key, each additional press
of the return key will step through the next boot parameter.
Pressing the ‘–‘ key, and then Return, will bring you to the
previous parameter, and pressing the ‘.’ (period) key and Return
clears the current field.
•
Change the value of inet on ethernet (e) to an appropriate IP
address and subnet mask.
11-3
TEAM U S E R S G U I D E
For instance, to assign the IP address 192.168.0.10 and subnet mask
255.255.255.0 to your TEAM, you would do the following:
CP BOOT> c
↵
Make sure all the following parameters are set as shown. Parameters
not shown here are left as is:
boot device
processor number
inet on ethernet (e)
flags (f)
target name (tn)
other (o)
: cpm
:0
: 192.168.0.10:ffffff00
: 0x0
: MusicamCP
: CPSYS
Continue pressing the return key until you get the CP BOOT prompt.
Check all parameters by entering the ‘p’ command at this prompt:
CP BOOT> p
↵
The display will now look similar to this (note that some values may be
different):
boot device
unit number
processor number
host name
file name
inet on ethernet (e)
gateway inet (g)
flags (f)
target name (tn)
other (o)
: cpm
:0
:0
: e=205.197.242.120
: ffffff00
: 192.168.0.10
: 205.197.242.129
: 0x0
: MusicamCP
: CPSYS
CP BOOT>
At this point, if your TEAM CP software is version 1.8.1 or later, you can
re-boot the TEAM. If the CP software is earlier than this, please contact
MUSICAM USA.
11.4 Enabling Streaming Audio
In order to enable the output stream, a sub-channel connection from
some source port (any network card) to any port of the CP card in slot 0
must be established. (For this example we use port ‘A’) When properly
configured, the streaming software will check the command and
machine state for validity and begin the flow of data out through the
11-4
TEAM U S E R S G U I D E
Ethernet port. Please note that slot 0, ports A through P are the only
valid destinations. Follow these steps:
•
Set the TEAM IP address (as above)
•
Set the algorithm to MPEGL3
•
Set the sample rate to 32 or 48 (kHz)
•
Use the NMC command to map the encoder to the Network
module. In the following example, the encoder is in slot 2 and
the network module is in slot 4. The bit rate is 128 kb/s therefore
the number of time slots used is 2, and for this example, we’re
selecting channel group 1.
NMC 2a 4n 2 1
•
Use the NMC command to map the Network module to the
Control Processor:
NMC 4n 0a 2 1
Additional audio channels from additional encoders can be added
similarly, selecting a different channel group and a different Control
Processor port.
11.5 Configuring the Format Server
When the output stream is enabled, a Format Server configured with
the TEAM’s IP address can stream the audio data from the TEAM.
Upon running the format server program for the first time, you must
configure the server to recognize any TEAM units connected to it. Since
multiple TEAMs can be supported, you can use the format server main
screen, shown in Figure 10-1, to manage the available units for
streaming:

11.6 Making Connections
A connection is an association between a port on the Control Processor
card of a particular TEAM and a TCP port on the Format Server host.
You can choose which output port number you would like of use, and
this value becomes part of the URL of the audio stream.
As an example, if you make a connection and set the output port to 9000
on a machine called StreamHost, the URL for that stream will be:
http://StreamHost:9000
To make a connection, select File and Add Connection (refer to Figure
1). When you do, a new connection will appear with a unique channel
number and some default values. To configure the connection, you
need to:
•
Supply the source TEAM number. This is the number that is
assigned to the TEAM when you configure it.
•
Supply the input port value. This is the port on the Control
Processor card of the TEAM to which the TEAM is sending the
data you wish to stream. For instance, to stream the data in the
11-7
TEAM U S E R S G U I D E
TEAM that's on a connection from the network card to port 0A,
you would choose 'A' as the input port for this connection.
•
Supply the output port value. This is the TCP port number from
which the data will be available for streaming on the host
running the format server, and is appended to the host named
after a colon in the URL.
Once you have configured all these values, you are ready to start the
flow of data. Clicking the start button in the output column will cause
the Format Server to synchronize with the TEAM and begin streaming
the data. When the Output Status reads "Streaming Audio" the data is
available on the output port.
When you start a connection, you cannot change any of its configuration
values until you stop it again.
If you remove or change the associated connection on the TEAM, it is
recommended you also stop and start the connection in the Format
Server.
All connections made will be remembered and restored when restarting
the Format Server. If the AutoStart option is set, they will also start to
stream if they were started when the Format Server was last shut down.
11.7 Deleting Connections
When a connection is no longer needed, you can remove it permanently
from the Format Server configuration by choosing File and then Delete
Connection. A window will appear asking you for the channel number
of the connection you wish to delete. This number is listed in the lefthand column of the main Format Server window. Simply select the
channel and click “Delete” to remove it. The channel numbers of other
connections will not change.
You can select multiple channels at once by shift- or control-clicking
them. When you click "Delete", all selected channels will be removed.
Deleted channels will not appear the next time the Format Server is
started.

It is recommended that the TEAM be placed in a rack with spacing of at
least 2U on top and bottom of the unit. In a rack with multiple units, a
solid piece of non-flammable baffle (e.g.; metal shelf) must be placed on
top and bottom with separation of at least 2U from the unit. If the unit is
to be installed in an enclosed environment, additional cooling may be
required.
There are no special requirements for removing power prior to the
power supply. The power cord is the main disconnect device.
For full compliance with all emissions requirements, it is recommended
that a shielded power cord be used with TEAM unit.
