An IP address is an 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. Your Tieline codec supports both DHCP (default) IP addressing and static IP addresses for dialing IPv4 connection end- points.

Merlin IP Codec User Manual Configuring Dual Mono Programs 14.4 A dual mono program allows a codec to create two simultaneous audio stream connections with different destination codecs. Configuring a program to dial two mono audio stream connections from a codec is very similar to creating a single audio stream connection.
Page 61
1. By default port 9000 is the port specified for the first IP connection made by any Tieline codec; port 9010 is used by default for a second IP connection. If you need to change this setting on your dialing codec, or in your Report-IT smart phone application, this will need to be adjusted accordingly in the answering codec.
13. Click Save Program to save settings. If the previous configuration is used then any codec dialing over IP1 (using default Tieline IP port settings) will be routed to output 1 on the codec and IP2 will be routed to output 2.
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 65
SIP dialing is only supported over point-to-point connections, not multi-unicast connections. Tieline G3 codecs do not support connections using AAC and will default to MPEG Layer 2 if an incoming call is programmed to use this algorithm. SIP Server Connections: Getting Started Registering codecs for SIP connectivity is simple.

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 78
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 remotes into a broadcast.
Data packets travel independently and arrival times can vary greatly depending on network congestion and the type of network used, i.e. LAN versus wireless networks. The jitter-buffer is encompassed with Tieline's SmartStream IP technology which can: Remove duplicate packets.
Page 80
Merlin IP Codec User Manual 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. It adapts automatically to the prevailing IP network conditions to provide continuity of audio streaming and minimises delay.
Page 82
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 84
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.
Merlin IP Codec User Manual setting of the packets sent. Any bandwidth partitioning schemes should partition over a small interval to ensure the codec jitter buffer does not empty and audio remains continuous. 15.9 Reset and Restore Factory Default Settings Several reset and reboot functions are available from within the Reset Functions menu.
Tieline recommends that the racks in which codecs are installed are thoroughly evacuated to ensure proper airflow from the bottom to the top. Where space is available, a 1RU gap between codecs will assist in minimising internal temperature build up.
256 kbps for a studio codec and 64 kbps for a field unit connection. 5. Use good quality equipment to connect your codecs to the internet. (Tieline successfully uses Cisco® switching and routing equipment.): If you are using a DSL or ADSL connection make sure you purchase a high quality modem that can easily meet your speed requirements.
