The Multirate menu enables viewing/updating the following parameters:
4.8.5.3.4.1 Multirate Enable/Disable
The Multirate Enable/Disable parameter controls whether the multirate algorithm
should be used to determine current optimal rates in both the uplinks and the
downlinks.
The default is Enable.
4.8.5.3.4.2 Uplink Basic Rate
The Basic Rate for all uplinks.
The default rate is the lowest rate BPSK 1/2 (rate 1).
4.8.5.3.4.3 Downlink Basic Rate
The Basic Rate for all downlinks.
The default rate is the lowest rate BPSK 1/2 (rate 1).
4.8.5.3.5 Voice Parameters
The Voice Parameters option includes a single parameter, Maximum Number of
Voice Calls:
4.8.5.3.5.1 Maximum Number of Voice Calls
This parameter sets the upper limit of simultaneous voice calls that will be
supported by the AU.

NOTE
The multirate algorithm should always be enabled. The option to disable it is available to enable
using a fixed rate to support certain tests. After each reset, the AU boots with the multirate enabled,
disregarding its status before the device was reset.
