INTRODUCTION
Trilogy’s pioneering IP based Intercoms address the demanding needs of today’s broadcast and professional media industries namely; expandable structure to cope as requirements change, choice of operator panels to suit application and user, simple installation over short and long distances and absolute reliability. They deliver a unique intercom solution that combines full programme quality audio with integrated IP capability.
Intuitive system operation allied to connectivity for both traditional and IP enabled intercom panels together with support for telephony and intelligent interfacing to analogue and SIP-enabled phone systems and portable devices make the Trilogy range undoubtedly the most flexible system available today.

Power Supply Cord Used as Disconnect Means
CAUTION: THE POWER SUPPLY CORD IS USED AS THE MAIN DISCONNECT DEVICE. ENSURE THAT
THE SOCKET-OUTLET IS LOCATED / INSTALLED NEAR THE EQUIPMENT AND IS EASILY ACCESSIBLE.
ATTENTION: LE CORDON D’ALIMENTATION EST UTILISÉ COMME INTERRUPTEUR GÉNÉRAL. LA
PRISE DE COURANT DOIT ÊTRE SITUÉE OU INSTALLÉE À PROXIMITÉ DE L’ÉQUIPMENT ET ÊTRE
FACILE D’ACCÉS.
The power supplies within the unit are a switched-mode design and will cope automatically with a wide input voltage range (see specification within each section). There are no user-accessible fuses on the power supply. The power supplies are crowbar protected against short circuits of the electronics.
Each power supply has its own, dedicated, IEC mains plug. These should be wired according to the instructions provided with a mating mains socket using a suitable cable. See above for earthing requirements.
Mains cable conductors are to be three-core (two-wire with ground), wire gauge 18 AWG (crosssectional area 0.75mm²) Jacket to be type SJT.
Covers are only to be removed by trained personnel. Shock hazard exists with covers removed; therefore disconnect the mains supply before removal. Interconnection between circuit boards and panels are all safety extra-low voltage (SELV) as defined by IEC/EN/CSA/UL 60950-1-200X. The equipment signal connections must only be connected to SELV circuits to prevent hazards from improper connection.

OINTS
There are now several different generations of Trilogy hardware control panels in service. Those which are part of the current range are listed in the following section.
The following general points should be noted:
• All control panels connect to the matrix using point to point topology. Each panel then utilises a single matrix port.
•
For Gemini only, models 700-38-00B and 700-47-xx can be connected to a Gemini matrix over a dedicated or existing IP LAN. An additional IP Panel Interface is required in the Gemini matrix to facilitate this mode.
•
Panel firmware may be re-programmed locally using the appropriate hardware adaptor, software utility and connection cable. Contact Trilogy for more information.

NPUTS
GPI inputs should be grounded to trigger the logical action. Pin 9 of the connector must be connected to a positive voltage to achieve this. A feed of +5V is provided on pin 5 and the link from pin 5 to pin 9 should be included in the external wiring.
If the input circuitry needs to be isolated from the panel voltage, the link between pins 5 and 9 should not be fitted. An external voltage can now be connected to pin 9 but an additional dropper resistor should be added if this voltage is >5V.

GEMINI ONLY - PANEL NETWORKING
9.1
I
NTRODUCTION
The panel networking system allows Trilogy Talkback panels to connect to a Gemini matrix using
Ethernet 10 Mb/s or 100 Mb/s copper cable connections. To support this, a specific expansion card
(IPPI) is fitted to the Gemini host and the panels must be network-capable – specifically, this means they must currently be part of the touch-screen range of panels.
TCP/IP copper cable connectivity has the advantages that customers can use existing networks and network cabling, that the connections can be extended and routed using off-the-shelf products and that many panels can be connected to Gemini via a single cable, reducing cabling requirements.
Unlike the non-Ethernet panels, which associate a panel with a Host and Subscriber by a point to point cable, the Host and Subscriber cannot be inferred from the Ethernet cabling and the user of a panel must identify which Host and Subscriber they wish to connect to. Two solutions, one a userfriendly method and the other, a catch-all manual method, are provided.
With a compliant network and the appropriate configuration, the system has been designed so that the user need never enter an IP address, thus simplifying deployment and maintenance.
Note that connection to panels is NOT made via the LAN connection on the back of the Gemini Host matrix; it is made using a dedicated network connector on each expansion board.

STEP
• Fit the IP Panel Interface(s) to the correct slot of your Gemini system.
•
Decide on an IP addressing policy. The system supports a range of manual (fixed) and automatic (DHCP) arrangements and the approach you adopt will be governed by your local networking infrastructure.
•
Set the network characteristics of each IPPI using the Gateway configuration editor.
•
Add keys to each control panel using the normal methods explained in the Gateway user
Guide.
• Connect panels to the network, configure their IP parameters using the panel menu system and finally select the identity of each panel from those available.

700-26-25 (IPPI)
9.3.1
Overview
One or more expansion card(s), type 700-26-25, can be fitted to each Gemini matrix. Each card has a single RJ45 connector which is the network connection point. The card should be connected from this connector to the appropriate network using CAT 5e/CAT 6 cables. The connection is polarity auto-sensing. The card supports 10 Mb/s and 100 Mb/s connections.
In common with other Gemini expansion cards, each 700-26-25 card supports up to eight panels.
More than one expansion card can be fitted, thus allowing additional panel connections. Expansion cards could connect to a cluster of panels each using a discrete private network for each card/cluster, Equally, it is reasonable to connect all expansion cards into the same network, perhaps using a switch located near with/the Gemini Host, as long as each card has a unique IP address.
All control messages are sent using TCP. The TCP data transport encoding is proprietary and is not compatible with any recognised protocol. Audio is sent uncompressed using RTP. The decision to use uncompressed audio intentionally favours low latency at the expense of signal bandwidth. One panel typically occupies about 500 kbits of bandwidth.
An expansion card must be configured before it can be correctly deployed. The configuration is made via the Gateway Configuration Editor. It is advisable to make configuration changes before the network connection is applied, in case the default settings clash with the network.
9.3.2
Adding a 700-26-25 IP Panel Interface
Before adding an IP panel interface, shut down the appropriate Gemini matrix. Identify the correct module position and remove any blanking panels which are currently fitted. Before inserting the card, release the black plastic fasteners by pulling outwards. Carefully insert the card, ensuring that it is located correctly on the guides. When the card is in place, push home the two fasteners. You may now reboot the Gemini matrix.
On the host advanced editor, set the expansion board type to EEB or IP Panel interface. If the existing type is set to audio expansion board, you will receive some error messages -- please ignore these and press OK. An additional tab is now displayed on the advanced editor to configure the new expansion boards. A sample is shown below.

Password This is set on a per-Subscriber basis. If set, a panel must be assigned with the same password to connect successfully. If not used, the password should be set blank.
9.3.3
DHCP Server Mode
As indicated above, the card has a built-in DHCP server which may be deployed for use on a network.
The intended primary purpose of this is where a network card is to be connected to a cluster of panels; the panels are connected to a local switch and then the switch is connected to the panel interface. The switch does
not
connect to any other network. In this instance, it may be desirable to enable the DHCP server and allow the panels to obtain IP addresses automatically, as opposed to manually setting up IP addresses on each panel.
Do make sure that only one DHCP server is present on a network segment. The expansion card DHCP server is sufficient to serve a number of panels over a private network but is not recommended to be deployed on a large network with many items connected.
To utilise the DHCP server, check the box named “DHCP server mode” and enter values for the IP address, subnet mask and gateway address (if used). In this case, the card itself will take the IP address set above and client devices requiring an IP address will be allocated an address starting at the base address + 1. Client devices are other IP panel interfaces and any IP enabled control panels which are running in DHCP client mode.

Overview
Panels that support connection via a network are the touch-screen range and the 700-38-00B 1U, 10 lever-key panel. These panels have an RJ45 connector which is the network connection point.
The panel IP address can be set manually or via DHCP.
Following an IP connection, each panel must be configured to adopt the identity of a particular
Subscriber. This is achieved in one of two ways:
• by entering the IP address and Subscriber number of the appropriate expansion card
• by identifying the Gemini host and Subscriber by name
The latter method is preferred but makes use of broadcast UDP messages which may be restricted on some networks.
9.4.2
Configuration
In the following sections, reference is made to configuration menu system of the touch-screen panels. It is assumed the user is familiar with accessing these menus and with their general layout and use.
Three different aspects of the panel configuration need to be considered when connecting to a network:
•
Panel type. See section 9.4.3.
•
Panel Network setup. See section 9.4.4.
• Network Connect, where the identity of the panel is configured. This is the subscriber
identity which the panel will adopt, from those configured with Gateway. See 9.4.7.
9.4.3
Panel Type
The panel type must be set before the unit can be connected to a network. The panel type dictates with which physical connection and message protocol the panel will operate. The type is setup using the Misc. Menu | Page 5. For an Ethernet connection, select either Gemini/Ethernet or Auto Detect.
Auto Detect mode will automatically identify and use whichever connection is physically present.

• From Connect, choose more
• Set the Host to the appropriate Gemini which is fitted with the IPPI [if you changed the connection mode, it takes around 30 seconds for a scan of potential
Gemini matrices to complete]
• Finally, pick the Subscriber identity from the 8 possible available on your selected
Gemini matrix [if your selected Gemini contains more than 1 IPPI, all subscribers will be presented. Only one is shown – keep pressing more to see all available]

IP address will bring up a screen to allow the IP address to be edited.
If the user has selected the ‘By IP’ Host Connection then pressing the Subscriber EDIT button to change the IP address will bring up a screen to allow the Subscriber number to be edited; this will typically be a number from 1 to 32. Note that the subscriber number must be in the range supported by the Host expansion card – for example, if an expansion card was fitted to expansion slot 3 (third slot) in a host, then only Subscriber numbers 17 to 24 are valid.

Subscriber Password
The user may enter a Subscriber Password using the Password EDIT button on Page 3. Note that the password is set in Gateway. If the passwords entered on the panel does not match that entered in
Gateway then the panel will not connect as that subscriber; this prevents unintended connection as a given Subscriber.

Both the panel and the expansion card have mechanisms to promote reliable audio transmission in the event of an unreliable network. These mechanisms have configurable parameters which are described here. In most instances, satisfactory operation will be achieved by accepting the default values. Please contact trilogy Technical Support for more assistance.
9.5.1
Jitter buffer
The jitter buffer attempts to compensate for audio packets arriving late or early. The audio from the packets is fed into a buffer, the jitter buffer. The buffer fills until it is nominally half fall then audio data is taken out of the buffer and fed to its destination (speaker, Gemini host). In an ideal world, as much audio data enters the buffer as is taken out and thus the buffer always remains half full. In practice this is not the case, not only does network unreliability potentially make the audio packets arrive late or early but the fact that the host runs asynchronously ensures that unless a correction is applied, the buffer will run dry or fill up at some point. Correction is achieved by throwing away or duplicating audio samples to ensure the buffer stays nominally half full. Please note that as the system is asynchronous, this
will
happen regardless; fortunately for speech, this approach is acceptable. The jitter buffer can be configured using two parameters.
Item
Jitter buffer size
Jitter buffer reaction
Description
This value sets the overall size of the buffer. The size must be set large enough to cope with the normal ‘wander’ of the audio packets. If it is too low the buffer will fail and entire packets of data will have to be discarded causing noticeable discontinuities in the audio. Setting too high a value does not improve audio quality but does worsen latency; the higher the value, the more lag there will be. A value of ‘5’ is appropriate for unstressed private networks. The buffer size should be set just high enough to ensure there is no failure.
This value determines how quickly samples are thrown away or duplicated whenever the buffer is not half full. Too low (quick) and samples may be affected more than they need to be. Too high (slow) and the buffer could fill up leading to dropped packets. A value of ‘7’ is appropriate for unstressed private networks.
9.5.2
Sequence Buffer
Audio packets are transferred using RTP which in turn uses UDP packets. The network may cause the packets to be sent out of sequence. The RTP mechanism can correct for this but to do this the incoming packets must be buffered. Whilst a bigger buffer can cope with more packets out of order it also introduces more latency. Thus the buffer size can be configured to trade sequence correction against latency.
The buffer is configured with one parameter as follows.
Sequence buffer size This value sets the overall size of the buffer. The size must be set large enough for a reasonable worst-case out of sequence event but no larger, so that audio latency is kept to a minimum.
Note that a value of ‘1’ indicates there is no buffer. A value of ‘1’ is appropriate for unstressed private networks. The buffer size should be set just high enough to ensure there is no failure.

Hints and tips
• Ensure that the network connection is plugged into the correct RJ45; this is the one on the far right when looking at the rear of the control panel.
• Check the lights on the RJ45 connectors are active. Normally, the Orange LED is permanently on to indicate a 100 Mb/s link and the green LED will flash to indicate data activity.
• Ensure that the panel is correctly configured: o Check the panel type is set correctly o Ensure the panel address is set correctly o Ensure the host connection is configured as required
•
Check the first page of both the network setup and connect setup menus. Both of these pages contain status information which is dynamically updated.
• Check that the correct password has been entered. The network connect error string will indicate if the password is wrong.
9.6.2
FAQ
Which IP ports does the ‘system’ use?
IP port numbers 50000, 50001 and 50002.
What if more than one panel have the same IP?
This will upset the functionality and correct operation is not guaranteed. In common with all networking equipment, all devices must have unique IP addresses. For this reason, enabling DHCP is preferable to setting addresses manually.
Do I have to set MAC addresses?
No, all devices have hard coded unique MAC addresses – no programming is required.
What if more than one panel tries to connect to the same Subscriber?
The first panel to attempt connection will win; the other panel will not connect. This could potentially lead to the wrong panel hijacking a Subscriber; setting passwords for critical Subscribers may assist in preventing malicious or inadvertent hijacking.
What if the expansion card IP address is changed?
If panels are connected using the ‘By IP’ method then the panels will no longer connect – all panels will have to be reconfigured for the new address.
If the panels are connected using the ‘By Name’ method, then the panels will continue to work without any intervention.
How are multiple expansion boards in one Host supported, assuming the expansion boards are routed into the same network?
If the panels connect ‘By IP’ then the appropriate expansion board IP and Subscriber number must be entered in the Panel. Despite being part of the same Host, different
IP addresses must be used depending on the subscriber number. If the panels are connected ‘By
Name’ then there is only one Host name required to identify a Host and the user will be presented with a list of all Subscribers available on all the expansion boards. For example, if two expansion boards are fitted and connected to the same network, the user of the panel can connect to one of up to sixteen Subscribers. The fact that the Subscribers are distributed across multiple expansion boards is hidden from the user.

ALLIES
Panel tallies are used to show an operator which routes to and from their panel are currently active.
A route can be active because an operator has chosen to speak or listen to someone else, or because another party has initiated a connection. Keys can be programmed with a variety of modes and the range of tallies reflects this. Tallies are also used to indicate transient states (e.g when local programming is underway) and error conditions (e.g. a route has been requested but is not currently available).
A total of 15 possible panel tally scenarios are identified below, although some of these are currently reserved for possible future use.
•
Panels from the Trilogy product range have two independent, fixed colour LEDs.
•
IRIS panels have one multicoloured LED plus a secondary graphic LED which appears on the
OLED display.
The following chart shows the range of tallies for the two panel ranges.
