Canopy System User Guide Configuring an SM for the Destination
pmp-0229 (Mar 2013)
279
This parameter governs the timeout interval, even if a router in the system has a longer timeout
interval. The default value of this field is 25 minutes.
CAUTION!
An inappropriately low Bridge Entry Timeout setting may lead to temporary
loss of communication with some end users.
SM Power Up Mode With No 802.3 Link
This parameter is present in only PMP 100 Series SMs. Specify the default mode in which this SM
will power up when the SM senses no Ethernet link. Select either
• Power Up in Aim Mode—the SM boots in an aiming mode. When the SM senses an
Ethernet link, this parameter is automatically reset to Power Up in Operational Mode. When
the module senses no Ethernet link within 15 minutes after power up, the SM carrier shuts off.
• Power Up in Operational Mode—the SM boots in Operational mode. The module attempts
registration. This is the default selection.
Dynamic Rate Adapt (PMP 100 Series)
This parameter is present in only PMP 100 Series (FSK) SMs. Whatever value that you set in this
parameter is overridden by a lock-down to 1X operation, if that is configured in the AP. In some
cases, disabling this parameter facilitates aiming. Be aware that a lock-down to 1X 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. See 2X Operation on Page 89.
Dynamic Rate Adapt (PMP 400 Series)
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. See 2X Operation on Page 89 and 3X Operation on Page 92.
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.
