Page 125: Configuring Sip Settings
SIP provides superior interoperability between different brands of codecs due to its standardized protocols for connecting devices and is intended to be used when connecting Tieline codecs to non- Tieline devices. Devices primarily use SIP to dial another device’s SIP address and find its location with a minimum of fuss.
Page 126 Merlin PLUS Manual v1.2 Realm details (sometimes). Program the Codec for SIP using the Web-GUI Use the Toolbox web-GUI to program SIP account registration details into your codec. Once these details have been entered into the codec, each time it is connected to a public IP address it will contact the SIP server automatically to acknowledge its presence over a wide area network.
Page 127: Configuring Sip Programs
Merlin PLUS Manual v1.2 Configuring SIP Programs 21.15 SIP programs are like a normal IP program to configure, with two small differences; entering a SIP address and selecting SIP as the Session Protocol. Important Notes: Before you start program configuration please note: SIP can only operate using port ETH1 on the rear panel of the codec.

Page 150: Selecting An Algorithm
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 151 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...
Page 152 Use MP2 algorithms at 64kbps mono or 128kbps stereo for high quality connections when using SIP, or use G.711 and G.722 if required. Tieline G3 codecs do not support connections using AAC and will default to MPEG Layer 2 if an incoming connection is programmed to use this algorithm.

Page 154: Configuring The Jitter Buffer
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 155 Merlin PLUS Manual v1.2 Algorithm Non-SIP Connections SIP Connections Linear (Uncompressed) Tieline Music Tieline MusicPLUS G.711 G.722 MPEG Layer 2 MPEG Layer 3 LC-AAC HE-AAC v.1 HE-AAC v.2 AAC-LD AAC-ELD Opus aptX Enhanced Programming Automatic Jitter Buffering (Default Setting) 1. Press the HOME button to return to the Home screen.
Page 156 FEC is being used. 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.
Page 157: Configuring Forward Error Correction
7. Select the local codec FEC setting in the Local FEC screen and press 8. Select the remote codec FEC setting in the Remote FEC screen and press The four FEC settings in Tieline codecs are outlined in the following table with their bit rate ratios. © Tieline Pty. Ltd. 2014...
Page 158 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.
Page 159: Configuring Encode/Decode Direction
Merlin PLUS Manual v1.2 consider reducing your FEC to minimize the likelihood of exceeding your bandwidth capacity. Here is another example, if you want 15 kHz stereo, you need at least 56kbps for the audio. 100% FEC requires at least 112kbps and 50% FEC requires at least 84kbps. If your uplink speed is 256kbps and you're on a shared connection, then choosing a lower FEC setting of 20%-33% may give you better results.
