MAC Parameters
The parameters that affect the BS MAC are grouped under mac. To configure the parameters under the MAC group, you
must get into the MAC configuration prompt by entering the following command:
MP16>configure mac
The prompt will change to:
MP16(mac)>
From the mac configuration prompt, you can show or set the following parameters:
* Time between transmission of DCD messages.
† Time between transmission of UCD messages.
‡ Time between Initial Ranging regions assigned by the BS.
**This parameter sets the downlink/uplink boundary of the TDD frame by setting the percentage of bandwidth allocated to the downlink. Set
the downlink percentage to a value between 10%-90% depending on the frame duration (see the following table). The remainder will be
allocated to the uplink.
Radio Parameters
The parameters that affect the BS radio are grouped under radio. To configure the parameters under the radio group,
you must get into the radio configuration prompt by entering the following command:
MP16>configure radio
