APZ 212 40 some changed behavior
The normal behaviour is that the CP becomes separated after changes to PS or RS, for instance, after PCORL and SAAII. All these changes shall however be followed by a SYBUP which automatically brings back the CP to normal state.
B side could be EX just as well as the A-side.
APZ’s built around standard commercial servers makes it harder to perform HW fault simulation in the old traditional way. Major re-design of the MAintenance Subsystem was required to achieve the same look and feel as in the recent APZ’s.In the first releases the diagnostics was not fully implemented to match earlier standards.

Architecture concepts in commonfor APZ 212 40 and APZ 212 50
APZ 212 40 was a large architectural step APZ 212 50 is a further but smaller next step
Several concept are inherited Run-time compilation Warm Standby & “Hot on demand” Handling of HW faults APZ 212 40/50 Software structure

Run-time compilation
Run-time compilation to ensure that market adaptations & other ASA corrections can be reused in APZ 212 40/50.
The ASA compiler use a ‘just in time’ principle, compiling ASA code when necessary and saving the result for later reuse. The compiler produce code according to two modes:
– BASIC mode: used for most blocks or when the test system is used. This code has full register coherency compared to earlier APZ’s, full JAM
– OPTIMIZED mode: used for function blocks that are heavily used in the system (~10% of the function blocks). These function blocks stand for around 90% of the code execution. This code is highly optimized and has less register coherency, limited JAM.

Warm Standby & “Hot on demand”
The standby side is fully loaded and running diagnostics In case of a controlled side switch, data is copied from the
executing side and traffic is moved without disturbance In case of a sudden, debilitating, hardware fault, there is a
system reload (with reload time 0, because software is already loaded) followed by a large system restart.
Restart and reload times will be favoured by the higher processor capacity.
Less hardware fewer hardware faults One repair in CP EX about every 5 years

Handling of HW faults HW fault detection implemented both in HW and SW Fault detection and replacement or board level Many fault types are fully recoverable, e.g. with no traffic
disturbance– Examples: RP errors, Match error on RPHB, One bit faults in
ECC supervised memories….– Recovery action depends on fault case, e.g. log event and
Soft Side Switch
Fatal HW fault in EX Restart, rank Reload– Transient data continuously from EX to SB– Error data is preserved in EX – Standby side fully loaded Reload time 0– Fast Large Restart– Load the command log, manually

APZ 212 50 Software structure
There are more levels of SW compared to APZ 212 3x– PLEX (as before)– PLEX engine (PES) – APZ-VM, ASA compiler– CPHW – OS, FW and drivers
Changes to PLEX engine and CPHW – Simple and transparent
Remote Upgrade of Firmware (RUF)– Possible to change FW on HW boards

APZ 212 50 load behaviour
Non-linear load– The non-linear load behaviour means that the CP at low load
seems to be less efficient than expected. – There are two main reasons why there is a non-linear relation
between offered traffic and CP load: The cache memory The automatic mode shift of the embedded compiler
The Gradual Change of Execution Efficiency– Immediately after a switch over from APZ 212 3x or APZ 212
40 to APZ 212 50 the call related code has not yet been generated by the ASAC.
– After normal traffic execution has resumed there are two processes ongoing that have some impact on the load per call
Compilation of code for new execution patterns Optimization of already compiled code

APZ 212 50 is very similar to APZ 212 40 from an operational view
Documentation differences between APZ 212 40 and APZ 212 50 available (2/1551-APZ 212 50 Uen)

APZ 212 50 combines the Intel Itanium and HP Carrier Grade Server running on Linux, integrated with the Ericsson Telecom Grade functionality giving a future proof platform for further system evolution.
– Real time performance: ~2 times APZ 212 40 – Memory up to 24 GW (PS, RS, DS, OS):
~3 times APZ 212 40– Safeguarding existing investments in AXE by backwards
compatibility– A switch to open sourced based APZ’s still provides same
good ISP figures in AXE, 5 nines

Questions and Answers
1) Does 1Gb Ethernet connection support "FastEthernet" ?? Yes. For example the system can handle both C/2 and C/4 APGs -
100 Mbit and 1 Gbit. Auto negotiation mechanism to set the speed 2)As the 212 50 supports either/both Serial AND ethernet OR both..how
does the customer ensure that they receive the correct number of each. O2 currently have (nor will have in near future) nodes with serial and
ethernet, however command DPRBP will probably give you what is needed.
3)Can the Base Packages be configured with a choice of 2GW DIMMs/ 1GW Dimms in order to ensure that all future expansions are catered for.
The three configurations from the presentation ( 8 GW(1 GW DIMM), 16 GW(2), and 24 GW(2) ) are the only ones provided, tested and supported.
If you like a 8 GW(2 GW DIMM), then it should be brought forward as a requirement. (It might not be technically possible though, due to maybe a minimum of occupied slots in configuration.)

Questions and Answers
4)Has Ericsson carried out a CANDI report on HLR fitted with 212 50?
Yes 5)Where is the document which describes the Delta between 212
40 V 212 50 capacity Capacity for APZ 212 50 is 2 times APZ 212 40. Is it an
estimate or is it measured? It has been measured in MSS and it is almost exactly 2 times. In HLR the capacity increase is bigger, but there are no figure for it.
6)Is the Blade solution available in R13 or R14? development work ongoing and so is not industrialised as yet
hence no target R-release defined for commercial sales.

Questions and Answers
7) Does the 212 50 require more Cooling or Power than the 212 40?
APZ 212 50 power consumption is 1500 W. How much for the APZ 212 40? The APZ 212 40 figure is 935 W. More capacity per W!
8) Can O2 have a statement saying 212 50 is compliant with EU Environmental regulations.
Statement of compliance is available
