14.3 Channel Allocation Strategies
The Vega allows configuration of the channel allocation strategy to be used for each DSL on
outgoing calls. Four options are available,
i)
Linear_down
– where the Vega will use the highest available free channel to make the
outbound call … use this mode when the attached device is configured to make outbound
calls using
Linear up.
ii)
Linear_up
– where the Vega will use the lowest available free channel to make the
outbound call … use this mode when the attached device is configured to make outbound
calls using
Linear down.
iii)
Round_robin
– in this mode the Vega remembers the last allocated channel and then tries
to use the next channel up from this for the next outbound call. (After reaching the highest
channel ID it restarts at the lowest channel again.) … use this mode when the attached
device is configured to make outbound calls using
Round_robin
mode.
iv)
Default
– if the DSL is configured as NT then the Vega will use the
Linear_up
scheme, and
if the DSL is configured as TE then the Vega will use
Linear_down
.
By default the Vega has chan_alloc set=
