First, verify that the correct channel cards have been installed and are displayed in the correct card slots. If provisioning the system without being connected to the unit, all of the cards will be shown as empty (with the blue Pleiades logo displayed). To change a card type, click on the card logo to bring up the selection window:
To provision individual channels on the card, press Configure. This brings up the VF channel configuration screen:
Just as for any Line circuit, individual Trunk circuit parameters can be set. This includes the Termination impedance, TX Gain and RX Gain, as well as Circuit Type (Loop or Ground Start, or DID). Individual circuits can be enabled or disabled via the Enabled check box. Individual circuits can also be set to Busy Out which forces them to not respond to on/off hook or ringing commands.
Note that unless the circuit is being used as part of the Versapath Feature Set, there is no operational difference between the circuit being labeled as a Line or a Trunk.
At any time, you can restore all of the default settings (for all four channels) by pressing the Restore Defaults button. The Reject Changes button undoes all changes that have been made to the four channels since the time the Configuration window has been active.
Pressing the Next button displays the channels on the next channel card; Previous displays the ones on the previous card.
When the Enable Versapath Processing box is checked, the channel is no longer considered to be part of a "standard" channel bank. This is where the Line and Trunk interface assignments will change the behavior of the channel. When a channel is defined as a Trunk, it must be assigned to an Inbound Trunk Group as part of a Logical Versapath.
In the example above, FXO Channels 25 and 26 have been set for Versapath processing. The display: (VP#1, ITG#=1) directly next to the channel number shows which Logical Versapath and Inbound Trunk Group this channel belongs to.
For a better description of all the Versapath features and how they relate to Lines and Trunks, review the Versapath Feature Set section.
Selecting the Use Packetized Voice check box allows the channel to be routed through either the Voice over IP or Voice over Broadband processor on the RAVE board. A Packetized channel will not be crossconnected to a specific timeslot on the Network Interface, but will be connected to one of the four Serial Interface Channels. The type of Serial Interface Channel determines how the voice calls are processed (either VoIP or VoBB).
In certain FXO configurations, Answer Supervision may be required. See the section on Answer Supervision for more information.
