Timing Mode
Select Timing Master. This BH will provide sync for the link. Whenever you toggle this
parameter to Timing Master from Timing Slave, you should also do the following:
1. Make no other changes in this or any other interface page.
2. Save this change of timing mode.
3. Reboot the BH.
RESULT: The set of interface web pages that is unique to a BHM is made available.
Modulation Scheme
This parameter is available for only the 20-Mbps BH. You can specify in this parameter
whether to use this 20-Mbps BH as a 10-Mbps BH.
Sync Input
Specify the type of synchronization for this BH timing master to use.
◦ Select Sync to Received Signal (Power Port) to set this BHM to receive sync
from a connected CMMmicro.
◦ Select Sync to Received Signal (Timing Port) to set this BHM to receive sync
from a connected CMM2, an AP in the cluster, an SM, or a BH timing slave.
◦ Select Generate Sync Signal where the BHM does not receive sync, and no AP
or other BHM is active within the link range. For link range information, see
Table 28 on Page 111.
Link Negotiation Speeds
Specify the type of link speed 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
Specify the frequency for the BHM to transmit. The default for this parameter is None.
(The selection labeled Factory requires a special software key file for implementation.)
In a 5.7-GHz BHM, this parameter displays both ISM and U-NII frequencies. In a 5.2-GHz
BHM, this parameter displays only ISM frequencies. For a list of channels in the band,
see Considering Frequency Band Alternatives on Page 100.
Downlink Data
The operator specifies the percentage of the aggregate throughput that is needed for the
downlink. For example, if the aggregate (uplink and downlink total) throughput on the
module 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%.
Color Code
Specify a value from 0 to 254. For registration to occur, the color code of the BHS and
the BHM must match. Color code is not a security feature. Instead, color code allows you
to segregate an individual network or neighboring Canopy networks.
Color code also allows you to force an BHS to register to only a specific BHM, even
where the BHS can reach multiple BHMs. On all Canopy modules, the default setting for
the color code value is 0. This value matches only the color code of 0 (not all 255 color
codes).
