    On the Web Interface, select the Connec ons Tab. As seen in Figure 5, this tab will populate with a list of available remote codecs to call. “Loopback” will connect BRIC-Link II to itself for diagnos c purposes. The next two default Connec ons will be “Comrex Lab Voice”...
  • Page 19 On the Web Interface, select the Connec ons Tab. As seen in Figure 6, this tab will populate with a list of available remote codecs to call. When the BRIC-Link II is “synced” with Switchboard, connec ons to other codecs in a user’s Switchboard account are simple.
  • Page 20 Firmware updates and installing licenses, such as a Switchboard Traversal Server License. Please note: In order to confi gure a BRIC-Link II unit for the fi rst me (without knowing the unit’s IP address), Device Manager must be run on a computer located on the same network (e.g. physical LAN connec on) as the unit itself.
  • Page 21 Generally, it is recommended to confi gure the Ethernet port of BRIC-Link II for a sta c IP. This will facilitate access to the Web-based Interface with a browser and allow for easier confi gura on of routers or fi rewalls (if necessary). If the BRIC-Link II is to be installed on a managed LAN, Comrex recommends consul ng with the IT services provider about obtaining a sta c IP address.
  • Page 22 (i.e., unable to log in). Device Manager has a network recovery tool to help with this: Network Recovery Mode. For security reasons, Network Recovery Mode is only available during the fi rst fi ve minutes a er a BRIC-Link II unit has (re)booted.
  • Page 23 Once the IP address is setup via the Device Manager, the rest of the setup and opera on of the BRIC-Link II is done via the Web User Interface. This process is addressed in the following sec on.
  • Page 24 LOGIN A er using Device Manager to fi nd or set BRIC-Link II’s IP address, begin confi gura on by opening a web browser and entering that IP address into the URL fi eld. Upon connec on to BRIC-Link II, a login screen will appear (Figure 12).

    By default, three factory remotes appear on the list. These remotes are used for troubleshoo ng connec vity: 1. Loopback: Allows for tes ng of localhost. BRIC-Link II will make an ac ve connec on to itself (input audio will be encoded then decoded and output from the same unit). This verifi es proper func onality of the BRIC-Link II, as well as the chosen audio profi...

  • Page 26: Dashboard Tab

    DASHBOARD TAB The Dashboard Tab is designed to be open during ac ve connec ons. As seen in Figure 16, it provides a quick view of some vital parameters. 1. The audio level meters give a quick indica on of send and receive levels. 2.

  • Page 27: Performance Tab

    PERFORMANCE TAB The Performance Tab includes informa on on data transmission and recep on rates from BRIC-Link II to ac ve remote connec ons. This allows for real- me monitoring of network quality during connec ons. Several headers are listed on this page and will drop down more informa on when clicked.
  • Page 28 CODEC CHANNEL FIELD Clicking on the “Codec Channel” header delivers informa on on the BRIC-Link II’s total receive rate and transmit rate (Figure 19), including informa on for mul ple connec ons when applicable. When mul ple transmit connec ons are ac ve, this will show an aggregate rate of all outgoing connec ons.
  • Page 29 UTILIZATION GRAPH The U liza on Graph (seen in Figure 21) indicates the incoming and outgoing u liza on of the network. The bars indicate the average data rate used by the system during each one-second window. It is possible that the size of these bars will vary because CrossLock (in some modes) has control over data rate through a technique called “thro ling”.
  • Page 30 For most CrossLock connec ons, the sliders should be le at their default Automa c Delay Mode se ngs. However, during connec ons on unusual networks, these sliders are available to quickly adjust the current delay se ngs. The most powerful way to stabilize any streaming connec on is to have the decoder add a delay buff er to the connec on.

    BRIC-Link II. It is o en unnecessary to create any new profi les since BRIC-Link II ships with a set of factory default profi les that cover most users.
  • Page 32 Next is the Channel op on, which allows for selec ng between a standard Comrex IP connec on (BRIC Normal) or one of the other connec on modes off ered by BRIC-Link II. Note that when using the CrossLock reliability layer, BRIC Normal mode is chosen here, as this is the protocol that runs with the CrossLock VPN.

    Encoder - Using this menu, users can select the encoder (or “algorithm”) used to send audio from this BRIC-Link II (under Local Se ngs) as well as the encoder used to send audio to this BRIC-Link II (under Remote Se ngs). The default value of the remote encoder is to follow the local encoder (i.e., it will send audio using exactly the same...
  • Page 34 For usage, it should always remain “on”. CrossLock Managed Delay - There are two ways BRIC-Link II can calculate its target delay, and therefore, how much decoder buff er to add. The fi rst is the BRIC-Normal way, and is the default for non-CrossLock connec ons.
  • Page 35 CrossLock connec ons, the buff er is increased to allow the use of error correc on, so the buff er is thus based on a combina on of the ji er histogram, and the round-trip-delay as calculated by the system. This will generally result in bigger decode buff...

    Note: Users should take note of any updated password, as a forgo en password may require a “factory reset” for users to regain access to BRIC-Link II (see page 16 for details on how to reset BRIC-Link II to factory default, or contact Comrex Tech Support for assistance.)

  • Page 37: System Clock

    NTP Enabled - Enables the use of NTP network me synchroniza on. This se ng is set to Yes by default. NTP Server - This allows users to set the address of the NTP server. This is set for 0.comrex.pool.ntp.org by default.

  • Page 38: Advanced System Settings

    Flow Control - Allows for selec on of the fl ow control method. Default is set to None with op ons for HW (RTS/ CTS) and SW (XON/XOFF). This has no func onal eff ect on BRIC-Link II. Parity - Users can select parity protec on with this se ng. Default is set to None with the addi onal op ons for Odd or Even.

  • Page 39: Bric Normal Settings

    fi eld must dial specifi cally to the new port number in order to connect to the BRIC-Link II. An outgoing call must be made to a specifi c port number in the form of IP-ADDRESS:PORT#.
  • Page 40 Public IP Override - Enable this in an environment where ports have been forwarded through a router to the BRIC-Link II. SIP protocol assumes no ports are forwarded and may have trouble connec ng if this func on is not enabled.

  • Page 41: Tcp Settings

    Outgoing calls are defi ned as TCP when their profi le is confi gured. BRIC-Link II normally listens for incoming calls on both TCP and UDP ports, and chooses the fi rst to arrive. If a TCP call is detected, BRIC-Link II will a empt to use the same TCP link to transmit in the reverse direc on.

  • Page 42: Network Manager

    BRIC-Link II. The primary Ethernet port for BRIC-Link II is confi gured for DHCP by default. In this confi gura on, BRIC-Link II will be assigned an IP address from a pool of available IP addresses from the network router upon boo ng. If BRIC-Link II is connected to the Internet, it should display connec on informa on for the Ethernet Port, including IP and DNS server addresses.

  • Page 43: Using A Static Ip Address

    DHCP opera on works well for individual connec ons, but may lack the consistency required for more prolonged use in a given loca on. Se ng a Sta c IP Address will allow BRIC-Link II to keep the same IP confi gura on every me it makes or receives a connec on.
  • Page 44 For example, when opera ng in a new studio in New York City, a user can create a Loca on called “New York” and apply the necessary IP se ngs for just that studio; then BRIC-Link II can be brought back to its own studio in Paris and simply change the Ac ve Network Loca on back to one called “Paris”.
  • Page 45 3G/4G CONNECTIONS BRIC-Link II allows the limited use of 4G Mobile data connec ons by u lizing the HotSwap feature with a Comrex Connect Modem. 3G connec on is also possible on certain carriers. The use of 4G modems as a primary network is not supported on BRIC-Link II.
  • Page 46 Preserve A er Reset - This op on ensures that changes to the unit’s network confi gura on will be preserved even if the device is reset to factory defaults. This se ng is disabled by default, and Comrex advises users to be cau ous when enabling it.
  • Page 47 CrossLock works, it’s helpful to fi rst focus on non-CrossLock connec ons (as shown in Figure 32). Without CrossLock ac ve, a codec will make BRIC Normal connec ons to BRIC-Link II on port 9000. Audio and connec on data are then sent over this single network port across the public internet, to be decoded on the far end.

  • Page 49 The Backup Remote feature works in conjunc on with a remote entry’s Local Timeout parameters, which are defi ned by the chosen audio Profi le. BRIC-Link II can sense an IP Connec on failure, and will wait for a me designated by the Local Timeout parameter.
  • Page 50 Fall Forward func on reestablishes connec on to the Primary Remote. Fall Forward - If the primary remote is restored while a backup remote connec on is ac ve, BRIC-Link II will detect a valid signal indica ng that the primary remote is once again available. When Fall Forward is enabled, it will automa cally disconnect the backup and revert back to the primary remote.

  • Page 57 Note: While units can follow mul ple Contact Lists that contain the same peer, a peer will only appear in one Contact List, to prevent “duplicate entries”. If the “Auto Default List” is used as Master List containing all units on an account, that List will now only show peers not already available in another Contact List.
  • Page 58 SETTING UP A SWITCHBOARD ACCOUNT The Switchboard Traversal Server is a service built and maintained by Comrex on the public Internet that facilitates connec ons between audio codecs by allowing them to share network and status informa on across a fl eet of other codecs.

  • Page 60 CONTACT LISTS TAB The Contact Lists Tab displays the “Contact Lists” available on the account (as shown in Figure 49), and allows new Contact Lists to be added. Contact Lists are like phonebooks; each codec can be added to a List (or several Lists), and each codec can choose which List (or Lists) to use when “calling”...

  • Page 61: Sharing Tab

    ADDING CONTACT LISTS Clicking “Add New Contact List” brings up a dialogue box that will ask for a List Name and a selec on of codecs to be included in the List (as seen in Figure 50). All of the available codecs on an account are listed to choose from. Clicking any of the codecs adds a “check” mark and includes that codec in the new List.

  • Page 62: Creating Shares

    Shares created locally are shown in the “Shares owned by this Account” sec on, and display a list of Units in the Share along with the name of the account that is being given access to these units. Users can modify the Share using the bu ons on the right side of the screen.

  • Page 63: Users Tab

    Click the name of the Share on the list to add a “check” mark, similar to selec ng units. Once the Share is “checked” all units within that Share will be visible to any codecs that are following the “Auto Default List”. They can now be connected as if they were on the same account.

  • Page 65 Similar to a DNS, this Directory Server func on stores real IP addresses and translates them into user-friendly names, but on a much smaller scale that is only relevant to Comrex codecs. Codec users can name their codecs and use those names to establish connec ons, rather than using IP addresses. The codecs themselves need only know...
  • Page 66 Because Switchboard stays on a fi xed IP address which is programmed into all Comrex codecs, this works naturally and easily. Once enabled, a codec in a group that is physically connected to the Internet will sync with the server. The server recognizes the sync a empt by the unique Media Access Control (MAC) address of the device reaching out to it (which the server knows from an internal database).
  • Page 67 This can work well for fi xed installa ons, but it’s not always an easy task to obtain that kind of security access on corporate routers. Addi onally, forwarding func ons are implemented diff erently depending on the hardware. One can easily imagine the complica ons of obtaining or managing port forwarding on the LAN when arriving at a new remote venue.
  • Page 68 Overall, Switchboard takes the complexity of interac ons between public and private internet and translates the user experience into a simple point-and-click methodology, giving Comrex codec users more freedom with less eff ort.
  • Page 69 HOW BRIC NORMAL CONNECTIONS WORK In BRIC Normal mode (the default mode of opera on), BRIC-Link II transfers all its audio data via the UDP 9000 protocol. This is in contrast to most web-based connec ons like browsing and email, which use the bidirec onal TCP protocol.

  • Page 72 As an example, a BRIC-Link II can be set to Always Connect To a codec at a transmi er site, with a Backup remote set in case the primary remote loses power. If lightning strikes and the primary remote goes offl ine, BRIC-Link II will keep trying to connect to the primary remote for the default 60 seconds before moving the connec on over to the backup remote.

    Time-to-Live (TTL) is a variable set by Mul cast encoders to determine how long a packet is processed before it is dropped by the network. The default value of TTL in BRIC-Link II is 0, which limits its use to within a LAN environment.

  • Page 85: Streaming Server Function

    STREAMING SERVER FUNCTION BRIC-Link II has the ability to act as a streaming server, delivering AAC and HE-AAC to compa ble PC-based media players. Currently tested media players include WinAmp, VLC and Windows Media Player version 12 or higher. As a streaming server, BRIC-Link II takes a passive role, allowing media players to “pull” the audio stream spontaneously.
