5.5 Conferencing

All S-Connect-x and S/T Connect board models, and T Connect-x With Conferencing boards allow you to include powerful conferencing capabilities in your telephony applications. In your application, you can use standard SwitchPath commands to establish and disconnect conferences. In addition, by issuing conferencing-specific commands via SwitchPath or the SW utility, you can control various conferencing parameters, such as gain or noise suppression. These parameters can be monitored for a given party, for a conference or for all conferences. You can also get status information at each of these levels.
Each conference is a local stream on an MVIP switch, with 32 timeslots. To establish conferences and connect or disconnect parties, you simply make connections between these local streams and standard switch streams. On the AG Connect board, streams 20-40 are used for conferences.
You can make up to 16 connections to conference streams at any given time. Each connection is called a conference seat. You can include all seats in a single conference, or divide them among multiple conferences. However, to ensure acceptable speech quality, no more than 8 seats should be connected to a single conference.
Each connection may be simplex (one way), duplex (two way), or pattern mode (in which a certain pattern of data is repeated in the timeslot in each frame). Typically, connections are duplex.
For more information on establishing conferences and using conference commands, see the Conferencing Developer's Reference Manual.
