Introduction 1

1. AVN-TB6 & AVN-TB6D 6 Button Talkback Intercoms

Introduction

The AVN-TB6 and AVN-TB6D are 6 channel talkback intercom control units from the Sonifex range of IP based AVN (Audio/Video/Network) products. The
AVN-TB6 is a freestanding version, which can be converted into a 1U rackmount using the AVN-TB6RK rack-kit. The AVN-TB6D is a desktop version that can
be fitted flush into a work surface if required. Both models offers similar functionality.

Fig 1-1: The AVN-TB6 Front Panel

Fig 1-2: The AVN-TB6D Front Panel

1 Introduction

These units provide broadcast quality audio communication between
studios, offices and different areas in a facility or building complex, using
RAVENNA/AES67 as the transport mechanism, allowing simple CAT 5 cabling
and expansion.

RAVENNA (of which AES67 is a subset) allows for the distribution of audio
across a network. The AVN range use RAVENNA as the communication
method providing compatibility with other AES67 systems.

Each of the 6 channels on the AVN-TB6 and AVN-TB6D can be configured to
provide communications with other remote networked intercom units or
AoIP streams, and an independently configurable page function can contact
selected units with priority over standard intercom calls if required.

There is a monitor channel that can route the audio from an AoIP source to
the headphones and speaker. This could be used to take an IFB feed or an
off-air transmission signal or simply to listen to any audio source.

A user configurable GPIO system, with 10 physical ports and 10 virtual
ports, can be used to control operational functions on local or networked
units, or drive outputs as selected states change, and a voltage free relay
contact can be used to operate external equipment.

A built-in web server provides complete configuration control of the units
and also allows for firmware updates and configuration backup. An Ember+
interface also gives access to the configuration options as well as providing
remote control and monitoring of the GPIO and virtual GPIO ports.

Installation 2

2. Installation

Network Connection

The AVN-TB6 and AVN-TB6D have 2 separate
gigabit network ports:

Upper Port: Configuration and control interface
Lower Port: Audio over IP (AoIP) interface

In an ideal installation, the lower port should
be connected to a dedicated network switch
that handles audio and audio related traffic
only. All other intercom units, AoIP sources and
destinations, and grandmaster clocks should be
connected to this network. The upper port can
then be connected to a separate network to
provide access to the embedded web server. With
this setup, potentially heavy network traffic on a
company LAN does not affect the performance of
the AoIP network.

The AVN-TB6 and AVN-TB6D and any other Sonifex
talkback intercoms can be used with a single
network connection using the lower (AoIP) port
as this also provides access to the embedded web
server. The talkback intercom units, AoIP sources
and destinations, and grandmaster clocks should
still ideally be connected to a dedicated network
switch.

Microphone

These units have connections for a microphone via a 3 pin XLR on the front
panel, or a headset via a 5 pin XLR. The headset connector is located on
the rear panel of the AVN-TB6. On the AVN-TB6D, the headset connector
is located on the front panel. Only one microphone or headset should
be connected. If phantom power is required, this can be enabled via the
webserver. See Audio - Microphone Settings web page on page 33 for
details.

GPIO

The GPIO connector provides 10 ports, individually configurable as either
inputs or outputs, via a 15 way ‘D’ type connector. Connection details are
shown on page 10 Outputs are open collector driven, and inputs are
active low. See GPIO Settings web page on page 37 for details.

Power Supply

The units can be powered from the mains via the supplied IEC lead, or by
using the optional external 12V DC power supply, part number AVN-DC150.
Please contact Sonifex Ltd sales for more details. Both power supplies can
be connected and powered at the same time to provide redundancy if
required.

5 Quick Start Guide

5. Quick Start Guide

This section outlines the steps required to get the AVN-TB6/AVN-TB6D
connected to a network and in a state where it can make and receive
intercom calls.

1. Connect the upper Ethernet port to a suitable network to access the
web server to configure the initial settings. By default this port is
configured to use the static IP address 192.168.0.100.

2. Apply power to the unit via the IEC mains connection or via an external
12V DC power supply.

3. Once the unit is powered, open a web browser and connect to the unit
by entering the IP address 192.168.0.100 into the browser address bar.
Once connected, the device information web page will be shown.

4. On the web page, select Network from the configuration tab and
configure the Ethernet and AoIP ports to the required settings. The IP
addresses assigned to the 2 ports must be on different subnets. For
example, with the subnet mask on both ports set to 255.255.255.0, if
the IP address on the Ethernet port is set to 192.168.0.100, the AoIP
port must be set to 192.168.x.y where x is not 0 and y is unique on the
chosen subnet.

5. Although not essential at this point, it is a good idea to assign a
recognisable intercom name so that other users can easily identify and
use services from this unit.

6. To simplify the configuration process, make sure the Auto Multicast
option is enabled. This removes the need to set the transmit AoIP
multicast IP address as it will be configured automatically based on the
AoIP port IP address. Once the settings on the network page have been
configured, press the submit button to save them to the connected
unit. When the network settings have been changed, the unit will
automatically restart. If the settings of the network port the browser
is connected to have changed, a new connection for the browser will
need to be established using the new IP address. If dynamic address
mode has been selected, the active IP address for the network port can

be determined by using the network address announcement function.
See Network Address Announcement on page 19 for details.

7. If a dedicated grandmaster clock, such as the AVN-GMC from Sonifex, is
going to be used as the master PTP clock for the network audio system,
the PTP profile on the AVN-TB6/AVN-TB6D will need to be set to the
current setting on the grandmaster device. On the web page, select PTP
Profiles from the configuration tab. Select the required profile from the
drop down list box and ensure that the domain number for the selected
profile matches the grandmaster setting. Press the submit button to
save the new settings. If no dedicated grandmaster device is used, the
connected intercom units will automatically establish a master clock
hierarchy. In this case, the default profile can be used.

8. Connect the lower AoIP port to the audio network.

9. On the web page, select Microphone Settings from the Audio sub tab.
Select the required microphone type, with or without phantom power.
Now change the microphone or headset gain so that metering LEDs
around the front panel rotary control peak in the amber section for
normal speech. Press the submit button to save the new settings.

10. The final step is to assign remote intercoms or AoIP streams to the
required channels. On the web page, select Basic Settings from the
Channels sub tab. Select the required remote intercom or AoIP stream
from the Available AoIP Sources list box at the top of the page. This
shows a dynamic list of currently available intercom devices including
those with IFB, and AoIP streams on the network. To configure a
channel for the selected AoIP source, press the corresponding assign
button. For sources that are not currently available, the source name
can be manually entered in the edit box for each channel. For intercom
assignments, a channel on the selected device will need to be assigned
to this unit in order to make intercom calls. Press the submit button to
save the new settings.

The unit should now have the minimum settings configured to allow
intercom calls between devices and AoIP streams.

13

Intercom Calls 6

6. Intercom Calls

Each channel button on the front panel can be assigned to a remote intercom
unit in order to make and receive voice calls. See the Channels - Advanced
Settings web page on page 30 for full details of the available options.

Making a Call

To make a call request, press the channel button assigned to the required
remote unit. If the called unit has the auto answer option enabled, the
call will be connected immediately. The button status for an active call is
described later in this section. If the called unit’s auto answer option is
disabled, the selected channel button will slowly flash using the colour
assigned to the default function for that channel. For example, if the default
function is talk and listen, and the colour assigned to the talk and listen
buttons is amber, the button will flash amber. If a call request is made to an
intercom that doesn’t have a valid channel assignment for the calling unit,
the call will be cancelled. To correct this error, assign the intercom name from
the unit attempting to make the call to a channel on the target unit.

Receiving a Call

When an intercom call request is received from a remote unit, the call will
be handled by the local channel assigned to the calling intercom unit. The
way the call is handled is dependent on the auto answer option setting for
the local channel. If the auto answer option is enabled, the call is connected
immediately. If the auto answer option is disabled, the channel button that
is assigned to the caller will rapidly flash using the colour assigned to the
requested call type. For example, if the calling unit has requested a talk only
call, the call will be treated locally as listen only. If the local colour assignment
for listen buttons is green, the channel button will flash green. If the call
signal is enabled, a repeated audible signal will be heard in the headphones
or speaker. The call is answered by pressing the flashing channel button and
the audio from each unit will be routed depending on the callers selected call
type.

During a Call

When an intercom call is connected, the channel button is illuminated using
the colour assigned to the call type. The intercom unit that initiates the
call always dictates the call type. If the monitor channel is active when an
intercom call is connected, the audio routed to the headphones or speaker
from the monitor source is automatically muted or dimmed according to
the monitor settings.

Ending a Call

An active call can be terminated by either party. To end a call, press the
illuminated channel button. The call is ended immediately and the button
illumination is turned off. If the monitor channel is active, it will return to
the normal state when all calls have ended.

Group Calls

Intercom calls can be made simultaneously to multiple remote units using
the group talk function. The group talk set can include any combination
of channels, see the Group Talk web page on page 31 for details. Group
calls are selected by assigning the group talk function to the user button,
see the Front Panel - User Button web page on page 32 for details. The
user button, linked to the group talk set, can then be used to make or end
a group call.

Call Signal

The call signal provides an audible indication that an incoming call is
waiting to be answered. It can be heard in the headphones and through
the speaker. If the call signal is not required, it can be turned off. See the
Channels - Advanced Settings web page on page 30 for details.

14

6 Intercom Calls

Auto Answer

The auto answer option is individually configurable for each channel. An
incoming call request on a channel that has this option enabled will connect
immediately. To change the auto answer settings, see the Channels ­Advanced Settings web page on page 30 for details.

Listen Button

Each channel has a default function option that selects the type of call
that is initiated when the corresponding channel button is pressed. See
Channels - Advanced Settings web page on page 30 for details. The front
panel listen button can be used to change the default call function to listen
only, talk and listen or talk forced listen. To override the default function
for a channel, press the listen button. The first press will select listen only,
and the button will illuminate using the colour assigned listen buttons. A
second press will select talk and listen, and the button will illuminate using
the colour assigned to talk and listen buttons. A third press will select talk
forced listen, and the button will flash alternately using the colours assigned
to both talk and listen buttons. A fourth press will cancel the listen function
and the button illumination will turn off. Once the listen button indicates
the required call function, press a channel button to call the assigned unit.
If a channel button is not pressed within 3 seconds of the last listen button

press, the listen function is cancelled.

Call Functions

The following table shows the corresponding call functions between the
calling and receiving unit. The default channel button colours for the call
type is also shown.

Table 6-1: Call Functions

The Talk Forced Listen call works differently to the standard talk/listen
functions. When this type of call is initiated, the call starts as a listen only
call. The callers channel button is illuminated using the colour assigned to
listen buttons, with a brief flash using the colour assigned to talk buttons.
The channel button on the receiving unit is illuminated to indicate a talk
call. The calling unit can then repeatedly press the channel button to enable
and disable talk. When talk is enabled, the channel button illuminates
using the colour assigned to talk buttons, with a brief flash using the colour
assigned to listen buttons. The channel button on the receiving unit is
illuminated to indicate a talk & listen call when the callers talk is enabled.
The receiving unit can end the call by pressing the channel button as per
other call functions. The calling unit ends the call by briefly holding the
channel button until the illumination has turned off.

Intercom Calls with IFB 7

7. Intercom Calls with IFB

Other models in the AVN Talkback range, such as the AVN-TB10AR, AVN­TB20AR and the AVN-TB20AD, can generate specific IFB AoIP streams.
These IFB streams from remote units can by assigned to the channel
buttons on the AVN-TB6 and AVN-TB6D by enabling the channel IFB mode.
See the Channels - Advanced Setting web page on page 30 for more
details. With IFB mode enabled, the selected IFB feed from the remote unit
will be heard in the headphones and through the speaker when the channel
is idle, and the channel button will flash briefly in the colour assigned to
listen buttons. Once a call is initiated and connected, the remote unit will
modify the audio content of the IFB stream and the receiver will hear the
required interrupt audio. Intercom calls with IFB are controlled in exactly
the same way as normal intercom calls.

16

8 Non-Intercom Calls

8. Non-Intercom Calls

The AVN-TB6 and AVN-TB6D allow any AoIP stream to be assigned to the
channel buttons. When a call is initiated to a non AVN Talkback device,
the unit does not attempt to communicate with the remote device for call
control. It simply routes the AoIP stream assigned to the channel to the
headphones and loudspeaker and unmutes the microphone audio routed
to the microphone AoIP transmit stream. If simply call indication is required
between devices, the GPIO ports on the unit can be used to provide control
and tally functions. See the GPIO Settings web page on page 37 for
details on how to configure the GPIO and relay settings.

17

Page 9

9. Page

The page function provides an easy method of making a high priority talk
only call to a preselected group of target intercoms. Up to 20 intercom units
can be selected as page targets and each unit can be configured to treat
received page calls as a priority over normal intercom calls. See the Page
Settings web page on page 36 for details.

Making a Page

To make a page call, press the page button. The button will slowly flash
green if at least one of the configured page targets is able to receive the
page. A configured target may not be receiving the page for a number of
reasons. These include:

• The target unit may be switched off or not connected to the network.

• The target unit may be already involved in a page call, either outgoing or
incoming.

• The target unit may be involved in an intercom call and the page priority
option on that unit is disabled, meaning that the intercom call takes
priority.

Receiving a Page

When a page is received and accepted, the page button fast flashes red. If
the page priority option is disabled, and an intercom call is currently active,
the page will be ignored.

During a Page

During a page call, the microphone audio signal from the paging unit will
be heard by the units that accepted the page. The page targets do not need
to respond to the page to hear the audio. Any current intercom calls on the
units receiving the page will be suspended and any active monitor channels
on the paging and receiving units will be muted for the duration of the page
call.

Ending a Page

A page call can only be terminated by the unit that initiated it. To end
a page call, press the green flashing page button. The page is ended
immediately and the button stops flashing. Any suspended intercom calls
on the target page units are resumed and any active monitor channels on
the paging and receiving units are unmuted.

10 Volume Control

10. Volume Control

The rotary encoder control on the front panel is used to set the volume
levels of the speaker, the headphones and the input levels for the various
audio sources.

Speaker & Headphone Volume

The volume control automatically switches from speaker to headphones
when a headphone jack plug is connected. To adjust the volume, turn
the rotary encoder control. The LEDs around the rotary control show the
current level between minimum (muted) and maximum (+12dB gain). There
are 21 LEDs and they are illuminated in a 1, 2, 1, 2 pattern giving 41 discrete
level steps. The LEDs will return to showing the microphone signal level if
no adjustments have been made for 1.5 seconds, or if the rotary control
button is pressed.

Call Channel Volume

The volume levels of the audio from remote units assigned to the call
channel buttons can be individually adjusted to compensate for varying
talk levels. This can be done during a call if required. To adjust the
channel volume, press the rotary encoder control which will then flash to
indicate that volume adjustment mode has been initiated. This mode will
automatically cancel if no further action is taken within 3 seconds. Then
select a channel to adjust by pressing the associated channel button. The
rotary encoder control and the selected channel button will now flash
using the colour assigned to the default function for that channel. The LEDs
around the rotary control show the current level in a similar way to the
speaker and headphone volume. Turn the rotary encoder control to adjust
the volume level. The volume adjustment mode will automatically cancel
if no adjustments have been made for 1.5 seconds, or if the rotary control
button is pressed.

Monitor Volume

The volume level of the audio from the selected monitor source can be
adjusted to compensate for varying levels. This can be done regardless
of whether the monitor is currently active or not. To adjust the monitor
volume, press the rotary encoder control which will then flash to
indicate that volume adjustment mode has been initiated. This mode will
automatically cancel if no further action is taken within 3 seconds. Then
press the monitor button. The rotary encoder control and the monitor
button will now flash green. The LEDs around the rotary control show
the current level in a similar way to the speaker and headphone volume.
Turn the rotary encoder control to adjust the monitor level. The volume
adjustment mode will automatically cancel if no adjustments have been
made for 1.5 seconds, or if the rotary control button is pressed.

Call Signal Volume

The volume level of the call signal routed to the speaker and headphones
can be adjusted to provide a comfortable mix level with other active audio
sources. The call signal volume control automatically switches from speaker
to headphones when a headphone jack plug is connected. To adjust the call
signal volume, press and hold the rotary encoder control until it starts to
flash blue. The LEDs around the rotary control show the current level in a
similar way to the speaker and headphone volume. Turn the rotary encoder
control to adjust the call signal level. The volume adjustment mode will
automatically cancel if no adjustments have been made for 1.5 seconds, or
if the rotary control button is pressed.

Network Address Announcement 11

11. Network Address Announcement

These units have a network address announcement mode which can be
used to determine the current settings for either of the 2 network ports:

1. Ensure that volume control mode is not currently active i.e. the LEDs
around the rotary encoder control are showing the microphone signal
level. Also, ensure no calls or pages are active.

2. Press the rotary encoder control button 6 times within 2 seconds. If the
button is not pressed 6 times within a 2 second period starting from the
first press, the network address announcement mode will not start.

3. Once the network address announcement mode has been initiated, the
rotary encoder control and channel buttons 1, 2, 4 and 5 will flash red.

4. Press channel 1 for the Ethernet port IP address, channel 2 for the
Ethernet port sub-net mask, channel 4 for the AoIP port IP address and
channel 5 for the AoIP port sub-net mask. Once a selection has been
made, the chosen details will be announced through the loudspeaker or
the headphones. If no selection is made within 3 seconds, the network
address announcement mode will be cancelled, and the rotary encoder
control and channel buttons will return to the non-illuminated state.

5. Once the chosen details have been announced, the unit return to normal
operating mode.

12 Embedded Web Server

12. Embedded Web Server

The AVN-TB6 and AVN-TB6D have embedded web servers which provide
easy access to all the configuration options through a web browser. It also
gives access to system information and allows the firmware to be easily
updated when new releases are made available.

model label. This makes it easier to identify the connected intercom unit,
especially when configuring multiple units at the same time. The right hand
side of each page has a brief help section that describes the content of each
section.

Information Tab

The pages under the Information tab provide device information as well as
a summary of the audio and GPIO assignments.

Device Information Web Page

The top part of this page shows details of the connected unit as shown:

To access the embedded web server, the unit
needs to be connected to a network via either of
the 2 network ports on the rear panel. The upper
port is the general access Ethernet port and
the lower port is the audio over IP (AoIP) port.
By default, both ports are set to static address
mode with the upper port IP address set to

192.168.0.100 and the lower port IP address set
to 192.168.1.100. If the network address mode
for the port to be used has been set to dynamic,
the unit will attempt to acquire an IP address
from a DHCP server or auto configuration if no
DHCP server is found. The current IP address
of these ports can be determined by using the
network address announcement function. See
Network Address Announcement on page 19
for details. If a port has yet to acquire an IP
address or has failed to link, the corresponding
IP address and subnet mask be announced as

0.0.0.0. Once the IP address of the required port
is known, simply type this into the address bar of
a web browser. The Device Information page of
the connected unit will be displayed. This is the
default page and will always be displayed first
when connecting to the embedded web server.
Each page of the web server shows the intercom
name in the upper right hand corner, under the

This information shows the current status of the unit as well as the software
versions of the various modules running on the unit. When contacting
Sonifex technical support, it is important to provide the information shown
on this page.

The lower half of the page shows the status of the Precision Time Protocol
(PTP) clock, as well as the configuration of the network ports as shown:

Fig 12-2: Lower Section of Device Information Web Page

The network IP addresses and subnet masks shown are the actual values
currently in use.

22

12 Embedded Web Server

Two additional pages under the information tab, provide a configuration
summary of the audio and GPIO assignments.

Audio Assignments Web Page

The Audio Assignments page shows the current channel and monitor
configuration as shown:

Fig 12-3: Audio Assignments Web Page

Each channel is listed with the intercom
name or AoIP stream name assignment if
any. Channels that are assigned to remote
sources indicate whether that source
is currently online. If it is online, the
assignment is shown in black and the AoIP
port IP address of the source is also shown.
If the target assignment is an AVN talkback
device, an AVN logo is shown next to the
channel number. Unavailable sources or un­assigned channels are shown in grey.

The Monitor Assignment shows the current
configuration and status of the monitor
channel. If the configured AoIP stream is
currently available, the assignment is shown
in black. Unavailable streams are shown in
gr ey.

23

Embedded Web Server 12

GPIO Assignments Web Page

The GPIO Assignments page shows the current GPIO, virtual GPIO and relay
configuration as shown:

Fig 12-4: Upper Section of GPIO Assignments Web Page

Each physical GPIO can be configured as
an input, output or it can be disabled. Any
configuration errors that will stop the GPIO
functioning are shown in red. For example,
GPIO 6 has been assigned as an input that
activates a virtual output. However, none of
the virtual GPIO have been set to an output
that is driven by GPI6. At the bottom of the
GPIO assignments is the list of functions that
trigger the relay – if any.

24

12 Embedded Web Server

Each virtual GPIO can also be configured as an input, output or it can be
disabled. As with the GPIO assignments, configuration errors are shown
in red. Virtual inputs require a remote virtual output driver to trigger the
input. The driver details are shown below the virtual input description and
will be grey if the driver service is not available. If the service is available, it
will be shown in black.

Fig 12-5: Lower Section of GPIO Assignments Web Page

Configuration Tab

The pages under the Configuration tab are split into groups and all of the
unit’s configuration settings can be edited here. Each page has a SUBMIT
button that sends the changes to the connected unit. The SUBMIT button
remains disabled until changes have been made on the page. Once the
SUBMIT button has been pressed, a busy indicator will be shown and the
page will be temporarily disabled until the changes have been written.

25

Embedded Web Server 12

Network Web Page

The Network page shows the current configuration of the Ethernet and
AoIP network ports. The intercom name is also set here.

Intercom Name – The intercom name is the user friendly name that
identifies the unit on the network. It is a good idea to assign a user name
or location as this is easily recognised by other users. The default intercom
name is made from the device ID and the 7 digit product serial number i.e.
AVN-TB6-1234567. The intercom name can only contain letters, numbers
and hyphens although it cannot start or end with a hyphen.

Address Mode – Each network port has its own independent address
mode which determines how the port obtains its IP address. When set to
dynamic, the unit will attempt to acquire an IP address automatically from
either a DHCP server or via auto configuration if no DHCP server is found.
The actual IP address will be shown on the device information page. When
static mode is used, the IP address and subnet mask values entered will be
assigned to the corresponding network port.

Static IP Address – This is the IP address that will be assigned to the
corresponding network port when static address mode is selected. It is
important to ensure that this IP address is not currently in use on the
network. These values are not used when the address mode is dynamic.

Static Subnet Mask – This is the subnet mask that will be used for the
corresponding network port when static address mode is selected. These
values are not used when the address mode is dynamic.

Fig 12-6: Network Web Page

26

12 Embedded Web Server

Auto Multicast – When this option is enabled and the address mode of the
AoIP port is set to static, the AoIP transmit multicast IP address, shown on
the AoIP Streams Web Page, is automatically configured based on the AoIP
port IP address. If the IP address of the AoIP port is changed, the multicast
address is updated. This simplifies configuration and ensures the multicast
address is unique on the network.

If any of the network configuration options are changed, the unit will
automatically restart to implement the new settings. If the IP address of
the network port that is currently being used to access the web server
is changed, a new connection will need to be made once the unit has
restarted. Otherwise, the new page will be shown automatically once the
restart is complete.

AoIP Stream Settings Web Page

The AoIP Stream Settings page shows the current configuration of the AoIP
options. The single transmit source on the AVN-TB6 and AVN-TB6D is for
the microphone/headset input.

Fig 12-7: AoIP Stream Settings Web Page

AoIP Stream Name Prefix – The AoIP stream name prefix forms part of
the AoIP stream name which will be displayed on remote devices when
searching for AoIP streams. This stream name is comprised of the AoIP
stream name prefix, set here for the microphone transmit source, and the
intercom name. For example, if the default microphone AoIP stream name
prefix “Mic” is used, and the intercom name is set to “DEMO-USER”, the
advertised AoIP stream name would be “Mic@DEMO-USER”.

DSCP – The DSCP or Differentiated Services Code Point value is used by
DiffServ to control the precedence of outgoing AoIP data packets. Network
hardware can use this value to ensure audio data has higher priority over
other network traffic. See Table 15-1 DSCP Names & Their Corresponding IP
Precedence on page 51 for more information.

Multicast IP Address – The multicast IP address is the IPv4 multicast
destination address for the transmit source. Remote network devices that
are configured to receive this source will use this IP address to access the

27

Embedded Web Server 12

audio data. It is important to ensure that the IP address entered here is
unique on the network as AoIP stream sources cannot share the same
multicast IP address. Multicast IP addresses should be within the range

224.0.0.0 to 239.255.255.255. If the Auto Multicast option on the Network

page is enabled and the AoIP port address mode is set to static, this
multicast IP address is automatically configured and cannot be changed.

and Custom. This drop down list selects which of the profiles will be active.

DSCP – The DSCP or Differentiated Services Code Point value is used by
DiffServ to control the precedence of outgoing PTP packets. Network
hardware can use this value to ensure PTP data has higher priority over
other network traffic. See Table 13-1 – DSCP Names & Their Corresponding
IP Precedence on page 51 for more information.

Profile Select – This drop down list selects the profile to view and change
settings. All of the available profiles can be edited.

Reset to Defaults – Selecting this checkbox and pressing the submit button
resets the selected profile to the default settings for that profile.

Delay Mechanism – This selects the method for calculating and maintaining
the clock synchronisation communication delay between master and
slave devices. Both P2P (Peer to Peer) and E2E (End to End) methods are
supported. The best method for a particular installation will depend on the
type of network hardware used. If all the switches are known to be IEEE
1588 capable, P2P should be used. Otherwise it is best to use E2E.

Announce Interval – This is the rate at which the announce message is sent,
one per the selected time. The announce message forms part of the Best
Master Clock Algorithm (BMCA) and contains the properties of the clock
which sends it. If a device receives an announce message from a better
clock, it will enter the slave state.

Announce Timeout – This is the time the unit will wait for an announce
message and is a multiple of announce intervals. If no announce messages
are received within the timeout interval, the unit will assume the role of
grandmaster.

Sync Interval – This is the rate at which the sync message is sent, one per
the selected time. The sync and follow up messages are sent from the
master to the slave to determine the difference in clock frequency. This
information is used in conjunction with the network delay to synchronise
the clocks.

Delay Request Interval – This defines the rate at which a slave clock sends
delay request messages to the master. The delay request message allows
a slave device to calculate the network delay from the slave to the master.
This option is only valid when using the E2E delay mechanism.

Peer Delay Request Interval – This is the rate at which a device exchanges
peer delay measurement messages. This allows each unit to track the
network delays between itself and its connected neighbours. This option is
only valid when using the P2P delay mechanism.

Priority 1 & Priority 2 – These values define a precedence setting used
by the best master clock algorithm when selecting a grandmaster clock.
Priority 2 defines a fine tune setting when multiple clock sources have
similar ordering criteria.

Domain – This defines the group of PTP devices that the unit will
communicate with.

Slave Only – This option limits the unit to being a slave PTP clock only.

13 Ember+ Interface

13. Ember+ Interface

The AVN-TB6 and AVN-TB6D have an Ember+ provider interface that
exposes all of the available configuration options. It also allows the GPIO,
virtual GPIO and the relay to be controlled and monitored by an external
Ember+ consumer.

Connecting to the Ember+ Interface

The Ember+ interface is available on both the Ethernet and AoIP network
connections using port 9000. Each of the configuration options are arranged
in branches grouped by function. Fig 13-1 shows a graphical representation
of the root structure.

Fig 13-1: Ember+ Root Structure

The configuration options are presented as either string or integer types.
Where possible, integer type options are enumerated to indicate what each
of the setting values are. A full list of the options and values associated with
each of the Ember+ parameters are on page 45.

GPIO

The GPIO branch of the Ember+ provider interface allows monitoring and
control of the GPIO ports and the relay. Fig 13-2 shows the structure of
each GPIO child node For further details on the configuration options, refer
to page 37.

Fig 13-2: Ember+ GPIO Branch Structure

43

Ember+ Interface 13

Each GPIO node has a similar set of parameters and functions:

Type Parameter

This enumerated integer parameter is the current port type.

Input Function Parameter

This enumerated integer parameter is the function that will be activated
when the GPIO port, when configured as an input, is asserted.

Input Action Parameter

This enumerated integer parameter is the operational mode of the GPIO
port when it is configured as an input.

Output Trigger Parameter

This enumerated integer parameter is the function that triggers the GPIO
port when it is configured as an output.

Status Parameter

The status parameter shown in Fig 13-2 represents the current state of the
GPIO port regardless of whether the port is set as an input or an output. A
value of 0 indicates the port is inactive and a 1 indicates the port is active.
This parameter has an Ember+ stream identifier and a consumer can
subscribe to it to automatically receive updates when the status changes.

Set Output Function

The set output leaf shown in Fig 13-2 is a function that allows control of
the GPIO port when it is configured as an output. The function exposes
1 argument called enable, which is an integer with a value of non-zero
for assert the output, or zero for de-assert the output. The function also
returns an integer result which reflects the current state of the GPIO output
similar to the status parameter. A return value of -1 indicates there was
an error invoking the function. If the GPIO port is configured as an input,
invoking this function has no effect.

Relay

The relay node of the GPIO branch of the Ember+ provider interface allows
the relay to be controlled by an Ember+ consumer. Fig 13-3 shows the
structure of the relay node. For further details on the configuration options,
refer to page 37.

Fig 13-3: Ember+ Relay Node Structure

Trigger Parameter

This integer parameter is the combined value of the functions that trigger
the operation of the relay. As multiple trigger functions can be selected, the
value shown is the sum of the selected items corresponding values.

Status Parameter

The status parameter shown in Fig 13-3 represents the current state of the
relay. A value of 0 indicates the relay is inactive and a 1 indicates the relay is
active. This parameter has an Ember+ stream identifier and a consumer can
subscribe to it to automatically receive updates when the status changes.

Active Function

The active leaf shown in Fig 13-3 is a function that allows control of the
relay. The function exposes 1 argument called enable, which is an integer
with a value of non-zero to activate the relay, or zero to de-activate the
relay. The function also returns an integer result which reflects the current
state of the relay similar to the status parameter. A return value of -1
indicates there was an error invoking the function.

44

13 Ember+ Interface

Virtual GPIO Control

The virtual GPIO branch of the Ember+ provider interface allows monitoring
and control of the virtual GPIO ports. Fig 13-4 shows the structure of each
virtual GPIO child node. For further details on the configuration options,
refer to page 38.

Fig 13-4: Ember+ Virtual GPIO Branch Structure

Type Parameter

This enumerated integer parameter is the current virtual GPIO port type.

Input Function Parameter

This enumerated integer parameter is the function that will be activated
when the virtual GPIO port, when configured as an input, is asserted.

Input Driver Name Parameter

This string parameter is the name of the virtual output on a remote unit
that drives the virtual GPIO port when it is configured as an input.

Output Trigger Parameter

This enumerated integer parameter is the function that triggers the GPIO
port when it is configured as an output.

Status Parameter

The status parameter shown in Fig 13-4 represents the current state of the
virtual GPIO port regardless of whether the port is set as an input or an
output. A value of 0 indicates the port is inactive and a 1 indicates the port
is active. This parameter has an Ember+ stream identifier and a consumer
can subscribe to it to automatically receive updates when the status
changes.

Set Output Function

The set output leaf shown in Fig 13-4 is a function that allows control of the
virtual GPIO port when it is configured as an output. To use this function,
the output trigger must be set to ember-consumer, and at least one remote
unit must have this output selected as the driver for a virtual input. The
function exposes 1 argument called enable, which is an integer with a value
of non-zero for assert the output, or zero for de-assert the output. The
function also returns an integer result which reflects the current state of
the virtual GPIO output similar to the status parameter. A return value of -1
indicates there was an error invoking the function. If the virtual GPIO port is
configured as an input, invoking this function has no effect.
