12 About Program Dialing
What Defines a Program?
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. Essentially a
program is like a connection profile with:
· A Program Name.
· IP address dialing details for up to 6 connection end-points or a multicast IP address.
· Specific connection profile details pertaining to algorithm, FEC, jitter buffer and bit-rate
settings etc.
Custom programs allow you to store connection settings for a range of peer-to-peer, multicast and
multi-unicast connections and retrieve or edit them easily at the touch of a button. Simple peer-to-
peer or multicast profiles can be created using the codec front panel, whereas multi-unicasts must
be created with the
Programs panel in the Toolbox web-GUI.
Using Programs to Dial between Two Tieline Codecs
Tieline Bridge-IT and Bridge-IT XTRA codecs operate similarly to Tieline G3 codecs. By default,
Tieline codecs send proprietary session data when connecting to each other in order to establish,
manage and terminate connections. When a connection between two codecs is established:
1. The dialing codec sends information about how the codec receiving the call should be
configured.
2. Once the codec receiving session data from the dialing codec has received information
successfully, it sends an acknowledgement to the dialing codec and streaming can
commence.
If you configure a stereo program on the dialing codec using a particular algorithm and bit rate etc.,
these settings will be configured on the answering codec when it connects. It is also possible to
lock a loaded program in a codec to ensure the currently loaded program cannot be unloaded by a
codec dialing in with different program settings.
Creating Programs
Simple peer-to-peer (point-to-point) programs can be created using the codec front panel. The
Toolbox web-GUI contains a Programs panel with a wizard for configuring program settings and
backup connections. Edit settings easily at the touch of a button and use existing programs as
templates for creating other programs.
Mono and Stereo Peer-to-Peer Programs
New peer-to-peer programs can be created using the codec front panel keypad (see 10 Quick
Steps to Connect ). If you know the IP address of the codec you want to dial then all you need to
do is enter this into the codec, choose your preferred connection settings and then press
CONNECT .
Front panel configured programs are automatically saved as Recent Programs which retain all
the audio stream dialing and configuration information. These Recent Programs are displayed
when you press the CONNECT button from within any menu except the IP Mode or SIP
Mode screens, or the Connect IP or Connect SIP screens.
