Routing Table
Selection Mode - Specifies the method of channel selection when selecting channels from the
trunk group for outbound requests:
Linear
• For gateways that have multiple channels per port, the highest free channel on the highest port
is used for the next call (Descending) or the lowest free channel on the lowest port is used for
the next call (Ascending).
•
For gateways that have a single channel per port, the highest free channel is used for the next
call (Descending) or the lowest free channel is used for the next call (Ascending).
Cyclic
• For gateways that have multiple channels per port:
– For Descending, within a port the channels are cycled highest to lowest. After using the
lowest channel, the next call is set to the next lower port's highest channel. When reaching
the lowest channel on the lowest port, everything wraps.
– For Ascending, within a port the channels are cycled lowest to highest. After using the
highest channel, the next call is sent to the next higher port's lowest channel. When
reaching the highest channel on the highest port, everything wraps.
• For gateways that have a single channel per port:
– For Descending, the ports are selected in a round-robin fashion, highest to lowest (with
wrapping).
– For Ascending, the ports are selected in a round-robin fashion, lowest to highest (with
wrapping).
Port/Channel Content - Each entry specifies the ports and channels that comprise the trunk group.
The following defines how the trunk group contents are specified:
– 1. A digit specified outside of parenthesis is interpreted as a port.
– 2. A digit within parenthesis is interpreted as a channel.
– 3. Both ports and channels are 1-based.
– 4. Ranges are allowed, and specified using a dash '-' for ports and channels but does not
allow combining a channel-range with a port-range (i.e. If specifying a port-range,
channel-ranges are not allowed).
– 5. A comma is used to indicate another range, channel, or port for any given trunk group.
– 6. An entry of just the '*' character represents 'all ports and channels'.
– 7. Whitespace is ignored.
Examples:
* = All channels in all ports.
1-4 = All channels in ports 1 through 4.
1,3 = All channels in ports 1 and 3.
1(1-16),2(16-30),4 = Channels 1 through 16 on port 1 and channels 16 through 30 on port
2 and all channels on port 4.
3(2,4-16) = Channel 2 and channels 4 through 16 on port 3.
