High availability

The MCC 3100 for Windows Mobile supports 1+1 redundancy. The CS 1000
NRS-SPS in the redundant configuration has two distinct IP addresses:
one for the active SPS and one for the inactive SPS. By configuring the
primary and alternate SPS addresses in the mobile device, the MCC 3100
for Windows Mobile can switch from one SPS to the other in the event that
one SPS stops working.
