2.1 Setting up your LQ environment

Prepare your environment by gathering the following equipment:

• LQ units (LQ #1 and LQ #2)

• (2) provided power supply units (PSUs)

• (2) Straight-through Ethernet cables

• (1) Network connection with dynamic host control protocol (DHCP) server

present

• (2) 2-wire or 4-wire devices to provide an audio connection to each LQ

1) Using the Ethernet cable, connect LQ #1 to LQ #2 using either using either LAN port on the rear of the unit.

2) Using another Ethernet cable, connect LQ #1 to your DHCP enabled network.

Figure 2-1 LQ device front panel display (4-Wire)

Note: The IP address will be allocated by DHCP (default mode). In the event

that the network does not serve DHCP or there is no network connection, the IP address will revert to a link-local address. See 8 Link-local environments for more information.

2.3 Create a Link-Group

Before linking units together, one LQ device must first be designated as the LinkMaster. This is accomplished by setting that device's role to Link-Master. Every other LQ device within the Link-Group will then be set into a Link-Member role which allows the linking of those units directly to the Link-Master.

In this example, LQ #1 will be left as Link-Master (default configuration) and LQ #2 will be linked to it.

1) Navigate to Home > Linking on the CCM of LQ #2.

2) Click Change Role to Link-Member.

Page 16

399G116 Rev D

3) Within the Master IP address field, enter the IP address as displayed on the LQ #1 device. Click on blue check mark or <ENTER> key to submit.

3.1 Using the power supply unit (PSU)

• LQ units are supplied with a 24 watt sleeve-locking power connector.

• LQ-R 1RU units are supplied with two 60 watt sleeve-locking power

connectors. Use either power connector, or both to guard against one power supply failing.

Note: When connecting the sleeve-locking power cable, be sure to push until the

connector locks into the device.

3.1.1 Understanding power display icons

You will be able to see the power status of your device is from:

• The front panel of the unit

• The device icon in the web based configuration tool (the CCM).

These indicators will show if the unit is using PoE or the PSU (LQ throw-down units), and which of the two power supplies (or both) are in use for the LQ-R units.

3.1.3 Power 2-wire beltpacks from the partyline

2-wire partyline beltpacks take power from the partyline. The maximum numbers are shown in the table below.

LQ series unit Power supply mA supplied to the 2-wire interface

(number of beltpacks powered by the

partyline)

LQ 24 watts 150 mA (~5 beltpacks)

LQ PoE 70 mA (~2 beltpack)

LQ-R 60 watts 250 mA (~10 beltpacks per pair of ports,

max 20 per device)

Page 22

399G116 Rev D

3.2 Using power over Ethernet (PoE) with 2-port units

The 2-port units will receive power from the LAN1/PoE connector if required (this is not the case for the larger LQ-R units).

When using PoE the LQ-2W2 supplies approximately 70 mA of power to the 2-wire interface.

Note: If you are powering more than two LQ devices from one PoE switch, please consult

the power output of the PoE switch, as you may reach the limits of its power capacity with more than two boxes.

If this happens, the device(s) will show a persistent flashing green light, and not move beyond the Clear-Com splash screen. This indicates that the device is continually booting and needs more power than the PoE switch or network is providing. In this case, consider using the supplied sleeve-locking power connector cable to power the device.

3.3 Re-boot system

The system will start its boot sequence immediately when power is applied. If you need to reboot for any reason, either cycle the power or press all four direction keys on the control panel on the front of the LQ unit at the same time.

Once joined to the Link-Group, all devices attempt to connect to all other devices within the group.

• Configuration and control of any device is possible through any other unit in the group

• Configuration information is both distributed and persisted within every node of the group

• Significantly reduces loss of service

5.1 A Link-Group

• A Link-Group can contain up to 6 LQ devices

• A Link-Group must have one unit designated as Link-Master

• The Link-Group performs a “best effort” approach to creating a mesh

network between all the devices within the group.

5.2 The Link-Master role

The Link-Master role serves three main purposes:

1) It facilitates Link-Group membership.

2) It is the owner of channel names, meaning that channel names will only persist (be maintained consistently) if the Link-Master is operational.

3) It is responsible for the synchronization and distribution of both configuration and device availability status throughout the Link-Group.

Group. Reachability of the Link-Master on TCP/UDP port 655 facilitates the routing of audio to/from the Link-Master but is not mandatory when setting up a LinkGroup.

Note: It is recommended that the IP address of the Link-Master is allocated statically.

When allocated by DHCP the IP address can change. If this happens the LQ devices will no longer be able to reach the Link-Master device.

Note: Any device can be set to Link-Master mode which is the factory default setting.

5.3 The Link-Member role

LQ devices that are not designated master will have the role of Link-Member. Joining a device to a Link-Group requires that device to be set to Link-Member role which will prompt the user to enter the address of the Link-Master.

If a Link-Member device loses connection to its Link-Master, the front panel LED will turn red until that connection is restored.

5.4 Linking units

The only way to join devices to a Link-Group is through the Linking page of the CCM. Only the IP address of the Link-Master is required during this set up.

See 2.3 Create a Link-Group for detailed instructions.

5.5 Linking over a LAN

This is the simplest way to link devices together. This type of environment enables the highest potential level of communication quality and the best availability of resources.

Link-Members are configured to join the Link-Group using the Link-Master's external IP and management port.

You might have to use port-forwarding. See

7. Internet Connectivity for more information.

Example port-forwarding at firewall: Port 80 forwarded to 6300 Port 655 forwarded to 6301

When linking over Internet or WAN, the IP addressing of the units becomes more complicated because the units use external addressing and port-forwarding to navigate firewalls. The LQ units must be able to reach the Link-Master.

The Link-Master uses TCP port 80 for management and TCP/UDP port 655 for audio. You will need to create port-forwarding rules within your firewall to make these ports externally accessible to the Link-Master device.

The Link-Master’s external IP and port will need to be configured within the

Network page of the CCM.

7 Internet connectivity

External (public) IP

Link-Master

Link-Member

LAN,WAN,

Internet

All devices within a Link-Group must have connectivity to the Link-Master on TCP port 80. When linking devices over the Internet, make sure that this connectivity is stable. Internet connection to an LQ device requires special configuration within your firewall (port-forwarding).

7.1 Getting an external IP address

When networking LQ devices over the Internet, an external IP address is required as a first step in making sure Link-Members can reach the Link-Master. The external (public) IP address must be static and non-changing. Normally an Internet Service Provider (ISP) will provide external addressing in Dynamic Host Configuration Protocol (DHCP) mode. This is not guaranteed to remain static but instead will change periodically. This will cause linking issues as the LQ devices will not be able to reach the master if the IP address changes. Therefore, it is suggested that you purchase a static address from your ISP. Failure to do this could result in a loss of service.

Note: Another alternative is to maintain DHCP addressing but use the Address

7.2 Port-forwarding

Reservation feature available in most managed routers. This will instruct the router to allocate a specific DHCP address to an LQ device identified by its MAC address. The unit’s MAC address can be retrieved through the LQ's front panel menu

In order to facilitate connectivity to an LQ unit that is behind a firewall, certain ports need to be mapped from your firewall to the LQ device. This mapping will forward traffic received on those ports from the Internet directly to the LQ unit.

• The Link-Group uses TCP port 80 for link initiation and Web management.

• All the units use port 655 (TCP and UDP) for group connectivity and audio

transmission.

Page 42

399G116 Rev D

7.3 How to configure the Link-Master to be externally reachable

Both the external IP address and the audio port forwarded within the firewall will need to be configured within the Link-Masters device configuration page.

7.3.1 Set Link-Master external IP address

1) Navigate to the Link-Master's network configuration page by clicking on the

Link-Master device in the Overview page and then the Network button.

2) Enter the external IP address which the Link-Master will be reachable from.

3) Enter the Port configured within the firewall that maps to the LQ device's

audio port (TCP/UDP: 655).

7.3.2 Link devices to the remote Link-Master

1) Join an LQ device to the Link-Group by entering the IP address of the device,

as displayed on the front panel, into your browser.

2) Navigate to the Linking page for that device and click Change Role to Link-

Member (if currently in Link-Master mode).

3) Enter the Link-Master's external IP address and management port using the

format [IP:Port].

Note: This must be the port that is mapped to port 80 within the firewall

Page 43

399G116 Rev D

34.50.16.7: 6300

Link-Master IP and external port if required.

4) If the Link-Master is reachable on its management port, the available device

IDs will be highlighted. Select one of the blue highlighted IDs and click Apply Settings.

5) Once the devices are successfully linked, all Link-Members will appear within

the Overview page.

7.4 How to configure Link-Members to be externally reachable

Clear-Com recommends that all units in a Link-Group are reachable over the Internet. In some cases this will mean external (public) addressing of the LinkMembers in a group as well as the Link-Master. This prevents a loss of service if the master is unobtainable for any reason and creates more efficient audio routing. Setting an external IP and interface port on individual Link-Members will reduce the risk of loss of connection if the Link-Master is unavailable.

Perform the following steps if connecting Link devices across more than two firewalls:

1) Navigate to the Networking page on each Link unit and input the external IP

address and port number. See below for example IP addresses and portforwarding.

8 Link-local environments

Ethernet cable

Link-local mode

• Any networked device will enter link-local mode if it is set to DHCP and no DHCP server is detected on the network.

• If both the laptop and the LQ device are in DHCP mode, they will revert to link-local when connected. This means they can communicate with one another as they are both on the same subnet (169.254.xx.xx).

8.1 What is link-local?

A link-local address is an IP address within the local segment of any network. Routers do not pass information to these as link-local addresses are not guaranteed to be unique beyond a single network segment. When first connected to a network, your LQ device will attempt to get an IP address via Dynamic Host Configuration Protocol (DHCP). If no DHCP server is available the unit will automatically enter link-local IP mode. A link-local IP address will take the form:

169.254.xxx.xxx.

8.2 Accessing an LQ unit when in link-local mode

Note: The units will operate in link-local, but for optimum performance it is

To access the CCM of an LQ unit in link-local, you must connect to it from a PC that is also in link-local mode.

Devices will revert to link-local mode if they are configured to DHCP and fail to find a DHCP address on the network or device they are attempting to connect to. A PC can be put into link-local mode by ensuring it is in DHCP mode and connecting it to the LQ unit that is in link-local with a standard Ethernet cable. The PC will look for a dynamically generated IP address (DHCP), and when it does not find one will enter link-local mode automatically.

Once the PC is connected to the LQ and in link-local mode, you can connect to your LQ unit by opening a browser window on the computer and inputting the unit’s IP address (from the front panel display) into the address field. This takes you to the Core Configuration Manager where you can configure the device as usual.

recommended that they are used with either static or DHCP network settings.

Page 46

399G116 Rev D

9 Network configuration

9.1 Dynamic host configuration protocol (DHCP) configuration

The default method for LQ devices to obtain an IP address is DHCP and this is the preferred method when setting up a Link-Group over a LAN.

Most networks allocate IP addresses using DHCP. The addresses provided are dynamic and will change from time to time.

9.2 Static configuration

DHCP is not recommended for the Link-Master and is not recommended for units linked to the master in some situations. An example of this is when the Link-Group has to navigate 2 or more firewalls.

In these cases you will allocate the network settings statically. To do this, navigate to: Device > Network in the Core Configuration Manager. See Fig. 9-1 below.

Figure 9-1 Core Configuration Manager, networking page

9.2.1 Netmask or subnet

The netmask or subnet divides the network into sectors for more efficient routing and is required when allocating a static IP address to an LQ device.

Page 47

399G116 Rev D

9.2.2 Gateway

Entry of this setting is optional. You will use it if setting up a Link-Group to navigate across subnets. If it is not explicitly stated, the system will revert to the device IP address.

9.3 Configuring an external IP address

You will use an external or public IP address when routing LQ devices over firewalls (this will almost always be the case when connecting over the Internet). A LinkMaster connected to devices beyond a firewall will always use an external IP address and an external port. Link-Members will use external addressing and ports if connecting over firewalls also. See 7 Internet connectivity for more detail on external IP addresses and ports.

10 Interface port configuration

10.1 Maximize bandwidth efficiency and audio quality

In the port-settings page of the CCM (configuration manager) you can adjust settings for each audio interface port within the Link-Group (up to 48 ports) on a per-port basis. This allows you to take network quality into account and maximize both audio quality and bandwidth efficiency.

Note: To minimize noise, use screened (shielded) cable when connecting 4-wire ports.

This is because the lower number in the jitter range represents the amount of time the LQ unit will buffer audio before delivering it to the port. A bigger jitter buffer setting will increase latency in milliseconds.

The Custom option within the Network Quality setting allows adjustment of the jitter buffer setting independent of bit rate and packet size.

14 FAQs

14.1 How can I find the IP address or name of my LQ unit?

The name and IP address of an LQ device can be found on the front panel display of the units and also in the Web GUI. The IP address and name of a unit can only be changed via the CCM (Web-based Core Configuration Manager).

14.2 What does a solid red light on the front panel keypad indicate?

A solid red light on the keypad shows that the unit has lost its IP connection to the Link-Master.

1) Make sure that the Link-Master’s IP address is reachable from the network

point where the Link-Member is connected.

14.3 What does a flashing red light on the front panel keypad indicate?

A flashing red light shows that there is an ID conflict within the LQ-Group, meaning that two LQ units are trying to connect to a Link-Group using the same link ID.

To resolve this you will need to undo the unit’s link to the Link-Master and then reapply the linking process to an available ID:

1) Within a Web browser, enter the IP address of the LQ device which is showing

the flashing red LED. This takes you to the Core Configuration Manager (CCM) for that unit.

2) Navigate to the device’s Linking page (Home > Linking).

3) Click the Change Role to Link-Master button and click Apply Changes.

4) Now reconfigure the link and the link ID. To do this, click the Change Role to

Link-Member button, and enter the Link-Master IP. Click the blue check mark or <Enter>.

5) Select an available ID slot (available IDs will be highlighted in blue) and click

Apply Changes.

14.4 What does a persistent flashing green light (more than 2 minutes) on the front panel keypad indicate?

The devices boot automatically when power is supplied and show a flashing green light on the front panel keypad while the system is booting.

If the device is booting (the flashing green light does not turn into a solid green light) for more than 2 minutes, and the display screen does not move beyond the Clear-Com splash screen, the most likely explanation is that the unit does not have enough power. This can happen if too many LQ devices are drawing power from the same PoE switch or network.

Please check the power supply provided by PoE to see if this is the case and consider using the supplied power connector cable to power the devices.

14.5 What types of 2-wire intercom do LQ Series units support?

• Clear-Com

• RTS TW

14.6 Can I connect Clear-Com intercom panels to LQ 4wire devices?

Yes, Version 2 firmware and later supports Clear-Com Eclipse ECS/EHX matrix to panel connections.

Matrix+3 connections are not supported.

399G116 Rev D

14.7 How are LQ Series devices powered?

• LQ throw-down units use local power (24 watt sleeve-locking PSU) or Power over Ethernet (PoE).

• LQ-R 1RU rack units use local power only (2 x 60 watt sleeve-locking PSUs).

14.8 How do I update the software in the LQ units?

Connect a Web browser to the LQ unit and navigate to the Upgrade section within the device configuration page (Home > General).

For more detailed information see 13 Upgrading your device.

14.9 How do I eliminate choppy audio being received by another LQ unit?

Choppy audio is usually the result of a port that has a Network Quality setting that is too high for the IP network. The following two approaches will help resolve this issue:

14.9.1 Reduce the Network Quality setting on the transmitting LQ unit’s port

1) Within a Web browser, enter the IP address of the LQ device which is

transmitting the audio to the receiving unit. This takes you to the Core Configuration Manager (CCM) for that unit.

2) Navigate to the LQ unit’s audio interface configuration page (Home > 2-

Wire/4-Wire).

3) Click on the Network Quality setting for the appropriate port.

4) Choose a lower network quality setting and click on the clue check mark to

apply the setting.

5) Repeat step 4 until the choppy audio is minimized.

14.9.2 Reduce the Network Quality setting on the receiving LQ unit’s port

To modify network quality on the receiving LQ unit’s port use the following steps:

1) Within a Web browser, enter the IP address of the LQ device which is

experiencing choppy audio. This takes you to the Core Configuration Manager (CCM) for that unit.

Page 68

399G116 Rev D

2) Navigate to the unit’s audio interface configuration page (Home > 2-

Wire/4-Wire).

3) Click on Network Quality for the appropriate port.

4) Choose a lower Network Quality setting and click on the blue check mark to

apply the setting.

5) Repeat step 4 until the choppy audio is minimized.

Note: The jitter buffer setting is designed to buffer audio received to prevent loss if there

is network jitter. Please be aware that the jitter buffer selection will directly affect the latency. This is because the lower number in the jitter range represents the amount of time the LQ unit will buffer audio before delivering it to the port. A bigger jitter buffer setting will increase latency in milliseconds.

The Custom option within the Network Quality setting allows adjustment of the jitter buffer setting independent of other settings.

14.10 How do I set the system up if I have to cross one or more firewalls?

As a minimum requirement for connectivity, the Link-Master must be reachable by all other Link-Members in the Link-Group. To achieve this, port-forwarding rules need to be created within the firewall which the Link-Master is behind. The ports that need to be forwarded are as follows:

1) 80:TCP. This is used for both link initiation and Web management.

2) 655:TCP/UDP. This is used for the transmission of all audio and data (call

signaling) between Link-Group members.

To set up a Link-Group with devices behind one or more firewalls, please observe the following example configuration:

Assume the following IP addresses and port-forwarding rules:

• 173.194.121.48 (external IP address)

• 192.168.1.100 (Link-Master network address)

• 6300 (arbitrary port chosen for port 80,the management port-forward

rule)

• 6301 (arbitrary port chosen for port 655, the audio/data port-forwarding rule)

1) Within the firewall, create a port-forward rule that forwards any TCP requests received on 173.194.121.48:6300 to 192.168.1.100:80.

Page 69

399G116 Rev D

2) Within the firewall, create a port-forward rule that forwards any TCP/UDP requests received on 173.194.121.48:6301 to 192.168.1.100:655.

3) Within the Link-Master’s Network configuration page, configure the external IP and audio/data port:

4) Within the remote unit’s Linking configuration page, configure the LinkMaster’s external IP and management port:

5) Repeat step 4 for each LQ unit to be part of the group.

6) For every Link-Member within the Link-Group that can be made externally reachable, navigate to the device’s Network configuration page and configure the external IP and audio/data port as in step 3 (optional).

These configuration steps will ensure basic connectivity within the Link-Group. For more detailed information see 7 Internet connectivity.

14.11 Why does the Link-Master need to have a static IP address?

The Link-Master needs to be statically addressed in order to prevent its IP address from changing. A changed IP address will result in loss of connectivity with the rest of the Link-Group.

Note: Another alternative is to maintain DHCP addressing but use the Address

14.12 What are the consequences if connection to the Link-Master is lost?

• Loss of audio. When connecting over the Internet, it is usually the case that the Link-Master is the only device that is reachable by the other units in the group. If this is the case, all audio will be routed through the Link-Master, creating the possibility of a single point of failure. To prevent this, be sure to facilitate connectivity between the LQ units in the group through portforwarding, described in 7 Internet connectivity.

Page 70

399G116 Rev D

• Prevents the ability of any of the LQ units to modify the name of any of the static

LAN, WAN ,

Internet

LQ 2W

LQ 4W

channel names.

• Prevents the distribution of device configuration changes throughout the Link-Group resulting in the possibility of having an inconsistent view of that configuration information depending on the perspective from which the device information is retrieved.

14.13 Does the LQ-4W2 pass call signaling?

Yes, but only call signaling originating from Clear-Com equipment. Call signalling to RTS equipment will be limited.

14.14 Can I link LQ-2W to an LQ-4W?

Yes, a 2-wire device can be linked to a 4-wire device.

14.15 Connectivity, including Web access to my LQ unit is intermittent, even though I am accessing it from within the same LAN.

The most probable cause for this is that an IP conflict exists. In this case, the IP address used by the LQ unit is already in use by another device within your LAN. The quickest and easiest way to check if this is the problem is to change the LQ unit’s IP address to an address that is known to be available and observe if connectivity to the unit is once again consistent.
