Software Release 4.1
8.3.1 Configuration Parameters
The Configuration page provides the following parameters:
Sync Input
The operator specifies the type of synchronization for this AP to use.
The operator selects Sync to Received Signal (Power Port) to set this AP to receive GPS sync
from a connected CMMmicro.
The operator selects Sync to Received Signal (Timing Port) to set this AP to receive sync from a
connected CMM2, an AP in the cluster, an SM, or a BH timing slave.
The operator selects Generate Sync Signal where the AP does not receive sync, and no other AP
or BHM is active within the link range. For link range information, see Table 2 on Page 15.
Link Negotiation Speeds
The operator specifies the type of link speed desired for the Ethernet connection. The default for
this parameter is that all speeds are selected. The recommended setting is a single speed
selection for all APs, BHs, and SMs in the operator network.
RF Frequency Carrier
The operator specifies the frequency that the module will transmit. The default for this parameter is
None. (The selection labeled Factory requires a special software key file for implementation.) For
a list of channels in the band, see
• 2.4-GHz AP Channels on Page 52.
• 5.2-GHz AP Channels on Page 53.
• 5.7-GHz AP Channels on Page 54.
Downlink Data
The operator specifies the percentage of the aggregate throughput that is needed for the downlink
(frames transmitted from the AP to the subscriber). For example, if the aggregate (uplink and
downlink total) throughput on the AP is 6 Mb, then 75% specified for this parameter allocates 4.5
Mb for the downlink and 1.5 Mb for the uplink. The default for this parameter is 75%.
If the AP is in cluster, then this parameter must be set exactly the same on all other
modules in the cluster.
High Priority Uplink Percentage
The operator specifies the percentage of the uplink bandwidth to dedicate to low-latency traffic.
When set, this percentage of RF link bandwidth is permanently allocated to low-latency traffic,
regardless of the amount of low-latency traffic that is present. No corresponding downlink
parameter is settable. Scheduling algorithms allocate the corresponding downlink percentage.
NOTE: Parameter settings for the high-priority channel require careful consideration
because bandwidth that is allocated to this channel decreases bandwidth on the regular
channel, regardless of whether high-priority traffic exists. See High-Priority Bandwidth on
Page 22.
