Attribute
Meaning
Dynamic Rate Adapt
This parameter is present in only PMP 400 Series (OFDM)
SMs. Whatever value that you set in this parameter is
overridden by a lock-down to 1X or 2X operation, if that is
configured in the AP. As with the
2X Rate
parameter in a
PMP 100 Series SM, a temporary lock-down to facilitate
aiming may be helpful. Be aware that a lock-down to 1X or
2X in the AP locks down the uplink and downlink between
the AP and all SMs in its sector, and thus would affect traffic
and performance across the entire sector. Hence, a temporary
lock-down for aiming is better done in the individual SM.
Frame Timing Pulse Gated
If this SM extends the sync pulse to a BH master or an AP,
select either
Enable
—If this SM loses sync from the AP, then
do not
propagate a sync pulse to the BH timing master or other AP.
This setting prevents interference in the event that the SM
loses sync.
Disable
—If this SM loses sync from the AP, then propagate
the sync pulse to the BH timing master or other AP.
Multicast Destination Address
Using Link Layer Discovery Protocol (LLDP), a module
exchanges multicast addresses with the device to which it is
wired on the Ethernet interface. Although some switches
(CMMmicro, for example) do not pass LLDP addresses
upward in the network, a radio can pass it as the value of the
Multicast Destination Address
parameter value in the
connected device that has it populated.
In this way, an SM can report to Prizm, for example, the
multicast address of a connected remote AP, and thus allow
Prizm to discover that AP. To allow this, set the message
mode in the remote AP to
LLDP Multicast
. Set this
parameter in the SM to
Broadcast
. The SM will pass this
address in broadcast mode, and the CMMmicro will pass the
address upward in the network, since it does not discard
addresses that it receives in broadcast mode.
Where the AP is not behind another device, the
Broadcast
mode will allow discovery of the AP.
Coordinates
Physical radio location data may be configured via the
Latitude
,
Longitude
, and
Height
fields.
