Software Release 9.1
Software Release 9.1 (SR 9.1) provides significant improvements in the operations
and maintenance of the iDEN system. SR 9.1 is supplied for equipment under
warranty and is offered as part of the Software Maintenance Program (SMP) that is
available as a subscription. The changes are summarized in Table 1-1.

(operations)
Requires Redundant Site Controller None
This allows site controller software to be loaded without taking the
cell out of service (in the background). An EBTS must have a
redundant controller to allow software is loads to the redundant
(standby) controller while the active controller processes traffic.
Controllers may then be switched and loaded.
Fast Site
Initialization
Not fully supported on VME ACG None
If a EBTS is not moved, but is re-initialized, this enhancement
bypasses the GPS synchronization of the initialization process
because Latitude and Longitude are remembered. This reduces
initialization time where line of site to the GPS satellites may be
blocked (buildings, similar obstructions). VME sites may track 6
GPS satellites, iSC sites may track 8 GPS satellites. If a site is
relocated, perform the GPS synchronization prior to service.
GPS Fault
Reporting
(additional stats
to OMC)
Not fully supported on VME ACG None
This improves commonality of hardware indicators and software
alarms and messages, GPS related reporting, and diagnostics for
coordination of information between the OMC and the field
technicians. Hardware is not changed.
RF uplink
Channel Quality
Statistics
None None
New statistics help Radio Link quality reporting:
1) The number of time below optimum SQE (20 dB)
2) The number of SQE per all calls
3) Average interference on idle channels
4) The carrier cabinet position
This identifies radios and sites with substandard radio link
performance
EBTS
ACG Enhanced
Redundancy
Requires Redundant Site Controller None
Provides greater recognition and automation of EBTS ACG
critical faults and cutover to the standby ACG in sites with
redundant ACGs. The EBTS site must be provisioned as;
redundant equipped or unequipped. Any background software load
is interrupted and superseded (cutover has priority of loads)
