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

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)

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)
