5.3.3 Channel Selection Mode
It is often desirable to select a method for choosing which channel within a channel pool is used to
place an outgoing TDM call. The channel pool configuration uses a channel selection mode
configuration option for this. The valid options are:
• Ascending Linear - The first (lowest logical) available channel is chosen to place the call.
• Ascending Cyclical - Channels are chosen upward sequentially from call to call. The selection
wraps back to the first channel when the limit is reached.
• Descending Linear - The last (highest logical) channel is chosen to place the call.
• Descending Cyclical - Channels are chosen downward sequentially from call to call. The
selection wraps back to the last channel when the limit is reached.
Note: Channel Selection Mode applies to outgoing calls only.
