.
robust reliability through
— fault detection and recovery
— built-in self-test and diagnostics
— auto identify, auto-configure and auto-test
capability for 10 times capacity of SN70EM
Shared-Memory
Parallel-Processing Machine
Independent scalable subsystems
Reduced cost of ownership.
Scalable capacity.
Software compatibility with both cross-threaded and non-cross-threaded
call processing architectures.
Hardware compatibility with Series I, Series II and Series III peripherals.
Order of magnitude improvement in core reliability, exceeding GR-512
requirements.
Compatibility with the full line of DMS-100 family products and all
existing software architectures.
Simplified "plug-and-play" provisioning of processor elements,
input/output processors and memory, allow this processor to enable
the large enterprise to make incremental capacity adjustments easily
and cost-effectively.
The life-cycle of XA-Core components is significantly extended over the
current single processor architecture. Instead of completing an upgrade
by replacement of the entire processor set, new XA-Core components
can be simply added along side existing investments.
With the XA-Core, spare processors can be used to share the
call-processing load, as well as for "hot" backup. Instead of remaining
in standby mode, these spares actively participate in the switch's
processing to broaden reliability and supplement capacity during
short-term overload situations.
Auto provisioning of processor elements, enhanced fault detection and
isolation, simpler extraction of failed cards and LED activity indicators
are some of XA-Core's enhancements to Operations, Administration,
Maintenance and Provisioning (OAMP). These enhancements can
contribute to significant savings in technician time spent on maintenance
activities.
