0dBFS Configure Tieline G3 Codec Audio Reference Scales Genie, Merlin, Bridge-IT and ViA codecs have more audio headroom than Tieline G3 audio codecs, therefore the audio metering reference scale needs to be adjusted when these codecs connect to a Commander or i-Mix G3 codec. The G3 metering scale is between -29dBFS and 0dBFS and audio levels should average around the nominal 0vu point at -14dBFS.
AES3 output. For example, if you are streaming audio using Tieline Music (32kHz sampling), file playback will be re-sampled to 32kHz if the SD card file is 44.1kHz or 48kHz. In this example the AES3 output sample rate will be 32kHz.

The codec uses the concept of 'program' dialing to connect using peer-to-peer, multicast or multi- unicast connections. A Program configures a Tieline codec to send or receive an Audio Stream. The attributes of each audio stream and associated connections are embodied within a program when it is created, including the configuration, dialing and answering parameters.

Use the numeric KEYPAD to enter the IP address of the codec you want to dial, using the buttons to enter the periods in the IP address.
· A multicast client program is used by codecs to receive multicast IP audio packets. Prerequisites: · Bridge-IT firmware v.1.01.00 r4219 or higher. · ToolBox web-GUI v.1.2.2.3 or higher. · A multi-unicast license installed in the server codec (Note: the multi-unicast license includes multicast server capability).
Use the procedure which follows to configure a multicast client program and allow the codec to receive multicast IP audio packets. Prerequisites: · Bridge-IT firmware v.1.01.00 r4219 or higher. · ToolBox web-GUI v.1.2.2.3 or higher. · A multi-unicast license installed in the server codec (Note: the Multi-Unicast license includes multicast server capability).
SIP peer-to-peer connection involves two codecs connecting to each other directly using an IP address, as you would for a standard Tieline IP call. The difference is that a Tieline IP call uses proprietary Tieline session data to negotiate call parameters (e.g. algorithm and bit rate) when a call is established, whereas a peer-to-peer SIP connection uses Session Description Protocol (SDP) for this purpose.
Page 44
SIP server you can connect by simply dialing the destination SIP address. Some SIP servers route RTP audio through the SIP server as well and Tieline recommends avoiding this type of server whenever possible. Otherwise you will be reliant on the SIP server for streaming broadcast audio packets and most servers are not designed for mission critical packet streaming.

SmartStream PLUS Redundant IP Streaming Tieline’s proprietary SmartStream PLUS IP technology ensures you’re always on the air. There are three levels to SmartStream PLUS IP streaming. 1. The codec can stream simultaneous redundant data streams and deliver seamless redundancy by switching back and forth, without loss of audio, from the nominated primary data link to the backup link if one fails and then subsequently recovers.

IP networks like the internet. These combined measures ensure Tieline is capable of offering a rock solid IP audio solution for distributing IP audio economically and efficiently across broadcast networks. See the procedures for configuring different programs using the web-GUI for more configuration details.
Lock or Unlock a Program in the Codec By default Tieline codecs will attempt to answer a call from another codec if possible. For example, if a mono program is loaded in the codec and a stereo incoming call is detected, the codec will adjust and load a compatible answering program.
Bridge-IT Manual v4.0 Connecting to the ToolBox Web-GUI There are two graphical user interface (GUI) options for configuring and connecting Tieline G5 codecs: 1. HTML5 Toolbox Web-GUI: fully configure codec settings, create dialing programs and dial, hangup and monitor connections.

Tieline G5 reference scale setting. The default Tieline G5 audio reference scale displayed on the PPMs is -38dBFS to 0dBFS (e.g. Merlin, Genie, Bridge-IT and ViA codec families). Using this reference scale audio peaks can safely reach 0dBFS without clipping, providing 18dB of headroom from the nominal 0vu point.
An IP address is a unique address to identify a device on a TCP/IP network. Your codec uses dual IP protocol stacks to allow your codec to work on both IPv4 and IPv6 networks. Tieline codecs support both DHCP (default) IP addressing and static IP addresses for dialing IPv4 connection endpoints.
IP interfaces (peers). Fuse-IP automatically distributes data over any two bonded interfaces. Bridge-IT only has a single LAN interface, however it can still connect as a Fuse-IP server or client. This means Bridge-IT can stream data between itself and another codec which is bonding over multiple IP interfaces.
This is particularly useful for identifying inbound callers when using line hunt answering mode. Any Tieline G5 codec dialing into a codec can display a designated Caller ID in the Connection panel. In the following example, Studio A and Studio B have called into a multi-stream codec using a specific caller ID, which is displayed next to the stream name.

Overview of Tieline Algorithms 1. The Tieline Music algorithm is optimized for audio bit rates as low as 19.2kbps with only a 20 millisecond encode delay. It offers 15 kHz mono from 24Kbps to 48Kbps. 2. Tieline MusicPLUS delivers up to 20 kHz mono from 48kbps upwards. It can also deliver up to 20 kHz stereo from 96kbps upwards, offering huge savings on your IP data bills and outstanding audio quality.
Page 173
For example, if MP2 algorithms are used, program delays will be much longer than when using Tieline Music or MusicPLUS algorithms. This is due to the additional inherent encoding delays involved when using MP2 algorithms. This can be a major consideration for live applications that integrate remote-crosses into a broadcast.
Page 176
32kHz, 44.1kHz and 48kHz sample rates as required. Tieline Music runs at 32kHz sampling and MusicPLUS runs at 48kHz sampling. G.711 and G.722 will always run at a 32kHz sampling rate (downsampled to 8kHz and 16kHz respectively).
· Manage delay dynamically based on current network congestion. · Manage forward error correction (FEC). Tieline codecs can be used to program either a fixed or automatic jitter buffer and the setting you use depends on the IP network you are connecting over. Over LANs, WANs and wireless networks the automatic jitter buffer generally works well.
Page 179
Configure the Jitter Buffer on the Answering Codec Session data is exchanged when a Tieline codec dials another Tieline codec and this configures the answering codec algorithm, bit-rate and jitter buffer etc. Depending on the capability of your network infrastructure, you may want to independently configure the jitter buffer settings on the answering codec.
Page 180
Bridge-IT Manual v4.0 Fixing Jitter Buffer Settings The default jitter-buffer setting in Tieline codecs is 500 milliseconds. This is a very reliable setting that will work for just about all connections. However, this is quite a long delay and we recommend that when you set up an IP connection you test how low you can set the jitter-buffer in your codec.
The amount of FEC required depends on the number of data packets lost over the IP connection. Tieline FEC transmits a secondary stream of audio data packets over a single connection. RFC 2733 compliant FEC transmits audio packets over a separate connection.

Page 183
FEC according to the available uplink bandwidth at each end for best performance. As an example, if you want 15 kHz mono (using the Tieline Music Algorithm) you will need at least a 24kbps connection for audio. Adding 100% FEC will add another 24kbps making your bit rate 48kbps plus some overhead of around 10kbps is required.
In-band RPTP data is automatically enabled when using the Tieline Music or MusicPLUS algorithms over IP. It is also possible to enable synchronized out-of-band data using any algorithm via the RS232 data port on the codec.

· When connecting to G3 codecs only in-band data is available via the Music and MusicPLUS algorithms. · Codecs using Bridge-IT firmware lower than v2.8.xx cannot activate relays on Tieline G3 codecs or send RS232 data to them. · It is important that you enable serial port flow control within the codec. Flow control regulates the flow of data through the serial port.
The session port uses the TCP protocol because it is most likely to get through firewalls – ensuring critical session data (including dial, connect and hang-up data) will be received reliably. The default session and audio port settings in Tieline codecs, for both TCP and UDP connections, are outlined in the Installing the Codec at the Studio section of the manual.

Diagnosing Port Blocking via the Remote Codec LQ If you attach your Tieline codec at the remote site to a LAN with access to the internet you can often dial and connect to the studio without any problem. It is less likely that a firewall will block outgoing TCP and UDP ports.
As an example: 1. Dial from site 1 to a Tieline test codec. 2. Dial from site 2 to Tieline test codec. If both of these connect successfully then the “outbound” TCP path for session data is OK, and the inbound UDP audio path is OK.
