2. Background • CIWG Report was Published 9/30/96 • CIWG was a Government-Funded IPT • Identified ATS Mass Termination Interface as a “Critical” Interface in Need of a Solution • Indication an Open-Architecture, Multi-Vendor, Standards Based Interface was Needed • See SCC-20/HIWG Web Site: http://grouper.ieee.org/groups/scc20/hiwg/ • IEEE Standards Coordinating Committee 20 and TC5 of the IEEE IMS Co-Sponsored the Receiver-Fixture Interface (RFI) Effort • Has Become a Family of Standards Efforts

3. USAF NAVY Challenge AF ATS CASS • Interoperability • Low Cost COTS Availability • Performance Repeatability • Minimum Maint/Support • Standardized Packaging • Spiral Development • Commercial and Military Applicability 1990’s 1980’s - TETS IFTE ARMY USMC General Purpose, Large, Dedicated ATE DoD Challenge to Define: Common Test Interface

11. IEEE-P1505.1 CTI Information Shown Subject to Change Until Standard is Balloted

12. IEEE-P1505.1 CTI • Need • Transportability/Rehost Capability of Test Program Sets • Requires a Standard Pin Map of Signals/Capability • Specific Implementation of: • Connector Modules Types per Slot • Segmentation • Scalability • Physical Mating Compatibility • Keying

13. IEEE-P1505.1 CTI - Overview • Transportability of TPSs Between ATE Systems • “New” ATE That are Legacy Upgrades • Desires for New ATE to be Able to Test Legacy Weapons Systems PLUS the New Systems • Factory to Field Test Compatibility • Required Study of Existing “Legacy” ATE Systems • CASS • TETS • IFTE • Etc., Etc., Etc. • Total of 3860 Signals are Mapped in Latest Version

14. CTI Segmentation/Scalability

15. P1505.1 CTI Functional Type Map

16. P1505.1 CTI Pin Map Overview

17. P1505.1 CTI Connector Blocks • CTI Does not Utilize all the Connector Types Defined in the IEEE-Std-1505 RFI Standard • Signal pins for 3 Amp service up to 750 MHz • Coax Pins for 3 or 5 GHz performance (In either 59 single-wide and 152 Pin, double-wide Module Blocks) • Power Pins 23 Amp service or Pins (In either 59 single-wide or 152 Pin, double-wide Module Blocks)

18. P1505.1 Levels of Compliance • Standard Allows Levels of Compliance • Mechanical – Each Slot has a Compliant (Correct) Connector Module • Full – For Populated Slots, Signals Match the Pin Map • Categories are Defined for Scalability and Compliance • Category 1 = Slots 6 thru 9 • Category 2 = Slots 1 thru 9 • Category 3 = Slots 6 thru 24 • Category 4 = Slots 1 thru 24 • Category 5 = Slots 1 thru 29 (All/Full Compliance)

19. P1505.1 Compliant Keying • Categories That are Fully Compliant MUST Implement the Keying Shown Below • Non-Compliant Systems MUST Implement a DIFFERENT Keying

20. P1505.1 Status • Some Systems Have Implemented Draft Standard • Very Near Initiating Ballot • Latest Information From SCC-20 HIWG Meeting Held 9/15 & 9/16 is: . . . . .

21. IEEE-P1505.2 Two-Tier CTI

22. IEEE-P1505.2 Two-Tier Interface • Not all Identified Requirements Included in P1505.1 • Multi-Tier Support • B-1B • F-15 • C-17 • IAIS • LMStar • Around 1000 Unassigned Pins From 1505.1 Effort • More Research Known to be Required Two Tier Electro-Mechanical RFI

23. Two-Tier P1505.2 Demonstrates Vertical as Well as Horizontal Scalability Horizontal Scalability Vertical Scalability

24. Summary • Hardware Interfaces Working Group Is Creating A Series Of Standards To Provide The Following Benefits • Standards-based, Open-architecture Interface Providing Multi-vendor Availability For Lowest-cost To The User • Improved TPS Rehost/Transportability Though A Defined Pin-map And Segmentation Scheme • Scalability For A Range Of ATE/ATS Capability And Sizes • Standards Group is Continuing Effort to Provide Benefits to the System Integrator and the User • Everyone is Invited to Join the Group by Attending Meetings and Completing a “Bluesheet” at: http://grouper.ieee.org/groups/scc20/bluesheet.html • Learn More at the SCC-20 Web Site: http://grouper.ieee.org/groups/scc20/
