Interoperability - Driving RequirementInteroperability - Driving Requirement
InteroperableJoint and Service C4
systems must possess the interoperabilitynecessary to ensure success in joint and
combined operations. Interoperability is thecondition achieved among C4 systems or
items of C4 equipment when information orservices can be exchanged directly and
satisfactorily between them and their users.To ensure C4 systems’ interoperability, allaspects of achieving it must be addressedthroughout the life cycle of a system.
• Additional principles furtheringinteroperability include:
CommonalityCompatibility
Standardization

CDL Links and HistoryCDL Links and History
• In the Late 1970s, CDL Was a Point to Point Link for Transmitting ISR Data
• In the Mid-1990 Time Frame, CDL Started Evolving to an IP Enabled Net-Centric Architecture
• The CDL Specification is IP Enabled and Supports Interoperability of Networked Data Links
• Common Waveforms Provide Product Interoperability Both Forward and Backward

“CDL remains the Department standard for ISR wideband links for manned and unmanned platforms to promote Service interoperability. As such, all ISR wideband terminal variants, including tactical CDLs (TCDLs), shall comply with the “Waveform Specification for the Standard Common Data Link (Rev F),” and its appendices, which address the Physical and Data Link OSI layers”*
* This policy was last reinforced by ASD C3I Dec 30, 2005
* ASD (C3I) Memorandum, Common Data Link (CDL) Policy, 18 October 1994.
