This section describes the sequence of events involved in enabling a trunk
Figure 1. Enabling a trunk
![The graphic is a simplified representation of the following text.](./trunken.gif)
- Somebody requested a trunk to be enabled, for example, by using the Blueworx Voice Response System
Monitor window (or via SNMP).
- The Blueworx Voice Response system manager sends an SL_TRUNK_ENABLE_REQ primitive
to the signaling process.
- The signaling process enables the trunk.
- The signaling process then sends an SL_TRUNK_ENABLE_CNF primitive
to Blueworx Voice Response.
- The trunk is now enabled.
- The Blueworx Voice Response system manager can now send SL_CHANNEL_ENABLE_REQ primitives for the individual channels.
